Intake system


I already wrote about the painting of the valve cover, but the story with the intake manifold was even more complicated... It was also, before me, painted with powder paint, in an equally "racing" yellow color! :) But in 24 years, the paint also began to peel off in places...


The experience of sandblasting the valve cover showed that it is very difficult to remove the powder paint even on a flat surface, not to mention all the "tricks" on the collector. Therefore, sandblasting is not an option. Peeling by hand is especially not an option. I already wanted to buy another collector, not painted. But then I was advised to try a paint wash - just like the one in the photo. Tried it - there is an effect!


Brushed the entire collector with that wash, and after about 15-20 minutes I got this picture - it's just cancer of the collector! :)


The paint was removed like a film - the result is quite good!


The remaining paint was processed again and removed manually with a metal brush. Also cleaned with a brush and washed the collector inside.


done


Now sandblast and the collector looks like new!


You can not paint. But the surface is porous and over time it will get dirty with dust and dirt. Therefore, I still decided to paint it with powder paint in silver color.






Part #1 - intake manifold (11 61 1 289 210). In fact, the number is slightly different (11 61 1 289 211), which is not in ETK - another mystery..

Part #2 - sealing gasket (11 61 1 726 012) - 1 pc. I use VICTOR REINZ 712703810 spacers
Part No. 3 - sealing gasket (11 61 1 726 010) - 4 pcs. I use VICTOR REINZ 712703710 spacers

Part No. 4 - sealing gasket (11 61 1 717 286) - 1 pc. I did not really like the price of the original gasket, and I did not find any analogues. That's why I cut it myself.
Part No. 5 - cover (11 61 1 708 858).
Part No. 6 - bolt M6X25 (07 11 9 919 926) - 3 pcs. Why is the quantity 1 pc indicated in ETK? - I do not understand.

Part No. 7...No. 10 is not used. These are parts for Jetronic.
Part No. 11 - spacer washer 6.4 (07 11 9 936 425) - 2 pcs.
Part No. 12 - bolt M6X16 (07 12 9 905 536) - 2 pcs.
Part No. 13 - elastic washer B8 (07 11 9 932 095) - 12 pcs.
Part No. 14 - M8 nut (11 61 1 713 432) - 12 pcs.

Part No. 15 - pin M6X35 (07 12 9 908 103) - 4 pcs. Throttle mounting.

Part #17 - not used.
Part No. 16 - bracket (11 61 1 277 431). Fastening the accelerator cable.
Part No. 18 - bolt M6X16 (07 11 9 904 357) - 3 pcs.

Part #19, #20 - not used.
Part No. 21 - pin M6X30 (07 12 9 908 102) - 2 pcs. Fastening of the wiring bracket.
Part No. 22 - pin M8X28 (07 12 9 908 147) - 1 pc. Fastening of the bracket of the diagnostic connector.
Part No. 23 - bracket (11 61 1 708 838). Additional mounting of the collector.
Part No. 24 - cap D=5.0MM (11 61 1 437 694) - 1 pc. It is put as a plug on earlier #5 covers for an additional outlet. I have a cover without an additional tap, so it is not used in my case.

Screw the bracket (#23) to the valve cover. We install the manifold gaskets.


To install the collector on the pins, and at the same time insert the crankcase ventilation tube with a spring into it, you need either an assistant or a third hand! :) I didn't have either, so I had to use materials at hand - a thin wire for a spring tie. So you can fully insert the tube, put rubber rings on it, and put the collector on it.


Then we pull out the wire and the tube is supported by a spring.


We screw the bracket (#16)


On the other hand, install the cover (No. 5) through the gasket (No. 4), and fix the collector to the bracket (No. 23)


I did not tighten these bolts, as it will be necessary to remove the cover to adjust the valves.

The collector is installed - now it is already something like an M20! :)

Collection_142. ETK_11_Engine. Cylinder head cover. Crankcase ventilation system

Cylinder head cover


My valve cover was previously powder coated red. But the paint peeled off in places, so I tried to remove it completely, but it turned out to be not easy... There was no time then, so I just painted the surface with ordinary black paint. It didn't turn out very well, but that's how it drove all the time. The paint peeled off again and the lid looked something like this.


But inside it was quite clean.


Especially compared to the Jetronic cover I bought a long time ago.


It temporarily covered the head of the cylinder block - also red, "racing"! :)


I also had another cover for Motronic, not painted - I decided to install it. But it was also very dirty inside. Therefore, I decided to remove the plate riveted from the factory. And it's not for nothing - there's just horror under it!


I don't know what to put in the motor on which she was standing, but there is a lot of dirt and soot and it was very difficult to wash it...


Looking at this, I decided to remove that plate on my lid as well. It was much cleaner there, but still a lot of soot.


It was not easy to wash the lids - I washed them with a solvent, brushes, several times. Then sand it. It was very difficult to get the powder paint residue off my lid. But as a result, I did get two completely clean lids.


Now you need to install the plates. At the factory, the plates were not riveted with rivets, but simply riveted pins cast together with the cover. That's why there are no holes there. So, I drilled the holes and cut the M3 thread into them. Used M3 stainless steel washers, spring washers and screws. This is important because the contact of aluminum with ordinary steel causes chemical corrosion.
Just in case, for additional fixation of the screws, I used a thread lock.


done


I hope that these cogs do not unscrew and do not fall into the engine! :)


In terms of color, I had options - silver, black and blue;) Or not to paint at all, but aluminum oxidizes and dirt stains remain on it. That's why I decided to paint. I powder coated one cover silver and will later paint the other cover black with silver stripes and BMW lettering. And the third one for Jetronic, maybe for an experiment, I will paint it in the color of the body ;)
And for now - a classic!


Part #1 - sealing gasket (11 12 1 730 271). I use the Elring 774693 gasket.
Part #2 - cylinder head cover (11 12 1 713 116). As I wrote above, they differ for Jetronic and for Motronic by the mounting of the intake manifold brackets. Although, all M20B25 engines are Motronic, but the cover is also Jetronic, only without the manifold bracket.
Part No. 3 - oil filler cap (11 12 1 716 993). I have two covers and both are not quite for the E30. One round metal from older "sharks" E21, E23, E28. The second square plastic one from newer E32, E34, E36. I don't really like the original cover for the E30 because it reminds me of a gas stove handle. :) Therefore, most likely, I will leave the square plastic one.

Part #4 - nut with washer M6 (07 14 9 156 628) - 8 pcs.
Part No. 5 - elastic washer B6 (07 11 9 932 099) - 8 pcs.

I didn't screw the cap on because the valves will still need to be adjusted before starting the engine.



Crankcase ventilation system




Part #1 - pipeline (11 42 1 265 376). It was not filmed.

Part #2 - clamp L16-30 (64 21 8 367 179) - 1 pc.
Part #3 - hose (11 15 1 708 801). I recently replaced it with a new Febi 12554.
Part #4 - clamp L18-24 (07 12 9 952 109) - 1 pc.

I will install the hose after installing the intake manifold and throttle.




Next, about the intake manifold.

Collection_141. ETK_11_Engine. Damper of torsional vibrations V-belt drive. Fan drive clutch fan

V-belt drive torsional vibration damper




Part #1 - damper of torsional vibrations (11 23 1 708 852). A rubber band is glued around the damper, which has a label that duplicates the label on the crankshaft.

Part #2 - belt pulley D=116MM (11 23 1 280 958). It is used only in the presence of power steering and / or air conditioning.
Part No. 3 - elastic washer B8 (07 11 9 932 095) - 6 pcs.
Part #4 - bolt M8X16 (07 11 9 913 612) - 6 pcs.
Part No. 6...No. 11 - bolt and crankshaft gear. It was not filmed. I just cleaned them and painted them on the spot.
Part No. 12 - V-belt 9.5X965 (11 51 1 711 091). I already wrote about it in the section about the generator - I bought all the belts from the manufacturer Continental. AVX10X960 generator belt.

So, we screw the damper and the pulley to the crankshaft flange. There is a special hole on the damper, through which it is put on the pin - that is, it is impossible to put it incorrectly. I used a threaded lock on the bolts just in case.


The duplicate mark on the damper matches the duplicate mark on the lower cover.


The damper is installed.

Fan drive clutch fan




Part #1 - fan 11-blade D=410MM (11 52 1 723 363). Since my entire cooling system is restyled, the fan is also for restyled cars. Before restyling, a 9-blade fan D=420MM (11 52 1 273 086) was installed.
Part #2 - BEHR fan clutch (11 52 1 740 962).
Part No. 3 - elastic washer B6 (07 11 9 932 099) - 8 pcs.
Part No. 4 - bolt M6X16 (07 12 9 905 536) - 4 pcs.
Part No. 5 - bolt M6X10 (07 11 9 913 426) - 4 pcs.
Part #6 - belt pulley D=129MM B=9.7 (11 51 1 271 424).
Part No. 7 - flange (11 51 1 277 387). It is an integral part of the water pump.
Part #8 - clutch nut. It is an integral part of the clutch.

Screw the coupling to the fan. I used a threaded lock on the bolts just in case.


It is interesting that the blades on the fan are not located symmetrically, with a different step between them.


We screw the pulley to the water pump. I used a threaded lock on the bolts just in case.
We put on and tighten the pump and generator belt.


Since I haven't bought a new power steering pump yet, and I haven't restored the air conditioner compressor yet, accordingly, there is nowhere to put their belts either. Therefore, their pulley remains empty for now.
I immediately screwed on the metal tube of the cooling system, because it will be a bit inconvenient to do it on the car. I will write about it later, in the appropriate section. The tube is attached with two bolts. One to the top cover.


Second to the special "ear" on the water pump.


Now screw the coupling with the fan. Please note that there is a left-hand thread!


Next, about the intake manifold and valve cover.

Assembly_140. ETK_11_Engine. Oil sump, oil measuring device

[URL='http://ru.bmwfans.info/parts-catalog/E30-4-doors/Europe/325i-M20/L-M/1985/browse/engine/oil_pan_oil_level_indicator/']Oil pan, oil gauge[/URL ]


I did not analyze anything here, so there is nothing to write about. But there is a nuance. :)



Part No. 1 - oil sump (11 13 1 720 754). I already boasted that after many years of driving on a low static suspension, my engine pan remained intact! :) I just cleaned and washed it. He did not paint. After all, it was not painted from the factory, so I left it like that.

Part #2 - sealing gasket (11 13 1 730 234) - was not removed.
Part #3 - bolt M6X20 (07 11 9 915 031) - was not removed.
Part #4 - rubber sleeve (12 61 1 276 240). Here is the same nuance! I bought it, but it turned out that it is not used on the E30.

I couldn't understand exactly where it goes... There are no holes for it anywhere.

And as it turned out, it is placed in part No. 5, which is used only on M30 engines.
Part No. 5 - protective shield (12 52 1 276 200). Not used.

The top hole is for this insert.

The sensor on the M30 is placed in the tray from below, so it is covered with a protective metal shield (No. 11 on the M30 diagram) so as not to cling to lying policemen. It is in that shield at the exit of the wire that there is a hole for this insert (#14 on the M30 diagram). Sensor and shield in M30 on 3 bolts.
On the M20, the sensor is on 2 bolts, so that shield together with this insert will not fit on the M20 in any way. Although, according to ETK, it also goes to M20 - this is a mistake.
Part No. 6 - M6 nut (07 11 9 905 543) - 2 pcs. There is an error in the quantity in ETK again.
Item No. 7 is not used.
Part No. 8 - pin M6X25 (07 12 9 908 100) - 2 pcs. There is an error in the quantity in ETK again.
Part #9 - oil level sensor (12 61 1 277 240). Before restyling with a round connector, after restyling with a square one.
Part No. 10 - ring of round section (12 61 1 277 602) - 1 pc. I bought it just in case, but I didn't change it. I don't see the point in this.
Part No. 11 is a plug instead of a sensor. Only for machines without a control system. In my case it is not used.
Part No. 12 - sealing ring A12X17-CU (07 11 9 963 151) - 1 pc. Copper.
Part #13 - threaded plug M12X1.5 (11 13 1 273 0930 - 1 pc. Plug for draining lubricant.
I haven't drained the old oil yet, so the plug is still in place.


The M8 bolt with washer is still visible in the photo. For some reason, it is not specified in the ETK - it is a bolt that is used to fasten the "ground" wire from the body to the engine.

P.S.
The intake manifold and valve cover are painted - now I can fully complete the engine assembly.


P.P.S
I am proud of the gift from my friends-teammates for my birthday! :)




The test drive was successful! :)


Then about pulleys and belts.

So, the generator bracket and the power steering pump are installed. My old pump is beyond repair, so I will be ordering a new one. But that will be later.
Almost the same with the compressor of the air conditioner - apparently it needs to be completely restored. Therefore, I also postponed it for later. For now, I will write about the compressor mounting bracket.
Let's go to the ETK section

The generator support bracket is also a bracket for the power steering pump. Although, there is also a separate bracket - only for the generator. This is exactly the bracket I had installed earlier, but I replaced it when installing the hydraulic booster. Therefore, I will immediately write here about the fastening of the power steering pump.
Power steering pump. support bracket




In the photo, there was a strange reflection on the plates - as if they were rusty) In fact, they are shiny and beautiful)

Part #1 - support bracket (32 41 1 264 642). The same bracket #1 as for the generator.
Part No. 2 (No. 11) - bolt M8X60 (07 11 9 901 797) - 1 pc. Bolt #4 for the generator.
Part No. 3 - elastic washer (07 11 9 932 095) - 6 pcs. Washer No. 3 for the generator.

Part No. 15 - self-locking nut (07 12 9 946 400) - 1 pc.

So, we assemble the bracket for the generator and the pump. Plates #8 and #9 will be installed later, together with the pump.


We fasten the bracket to the engine block with two bolts from the side and one bolt from the front end.




Next, about the details of the generator.
V-belt




Part #1 - V-belt 9.5X965 (11 51 1 706 710). I bought all the belts from the manufacturer Continental. AVX10X960 generator belt.

Part #2 - insulating part 8/5MM (12 31 1 286 664) - 1 pc. Plastic cover on the terminals of the generator. Plastic washers for generator terminals and nuts with washers for wiring terminals are not specified in ETK.
Part No. 3 - BOSCH generator capacitor (12 31 1 356 564) - 1 pc. According to the Bosch number (0290800036), it is much cheaper.

Part No. 4 - elastic washer B6 (07 11 9 932 099) - 1 pc.
Part No. 5 - bolt M6X8 (07 11 9 913 420) - 1 pc.
Part No. 6 - generator ground wire L=170MM (12 52 1 312 124) - 1 pc. In the original, it is red for some reason - strange. I made it myself from a brown wire, like all "ground" wires in BMW.


I had no complaints about the operation of the generator, but it did not look very beautiful, so of course I also completely disassembled and restored it. Replaced both bearings, brushes, contact rings of brushes, rubber sealing ring, rubber bushings, capacitor. Everything else is cleaned, painted and galvanized.


Several types of generators were installed on the E30. In my case, it is an 80A generator - Bosch Type N 0 120 469 619.
Alternator parts for 80A




Part No. 1 - nut M14X1.5 (07 11 9 901 309) - 1 pc.
Part #2 - spring ring B14 (07 11 9 933 148) - 1 pc.
Part #3 - pulley D=66MM (12 31 1 288 238) - 1 pc. It consists of five parts - two pulley "plates" and three washers.

Part No. 4 - impeller (12 31 1 735 306) - 1 pc.
Part No. 5 - key 4X5 (07 11 9 951 453) - 1 pc.
Part No. 6 - drive support (12 31 1 288 458) - 1 pc. Front cover.
Part No. 7 - retaining ring (12 31 1 276 226) - 2 pcs.
Part No. 8 - spacer washer (12 31 1 268 420) - 4 pcs.
Part #9 - bushing 75 SHORE LANG (12 31 1 268 433) - 4 pcs. I used the 01612 Febi analogue.
Part No. 10 - sleeve (12 31 1 276 227) - 2 pcs. Metal guide sleeve for the bolt.

Part No. 11 - bearing 47X17X14 (12 31 1 722 979) - 1 pc.
Part No. 12 - mounting plate (12 31 1 727 7400 - 1 pc.
Part No. 13 - rotor (12 31 1 288 423) - 1 pc.
Part No. 14 - bearing 28X12X12 (12 31 1 714 521) - 1 pc.
Part No. 15 - generator winding (12 31 1 727 758) - 1 pc.

Part No. 20 - bolt (12 31 1 747 251) - 2 pcs.
Part No. 21 - bolt (12 31 1 727 760) - 3 pcs.
Part No. 22 - bolt (12 31 1 738 099) - 1 pc. Long screw for the ground wire.
Part No. 23 - generator "brushes" (12 31 1 727 756) - 1 pc. Set of "brushes" Bosch (1127014022).

Part No. 24 - rotor repair kit (12 31 1 727 762).

We install rubber bushings in the front cover and metal guides, fix them with washers and a retaining ring. If you look carefully at the ETK scheme, the upper and lower guides are installed from different sides. This is not accidental, and it is important! Previously, I did not pay attention to this and put bushings on one side. At the same time, the generator becomes a little oblique, and probably that is why the upper rubber sleeve was constantly wearing out and the belt began to squeak. The bushings protrude at different distances and this compensates for the difference in the plane of the lower attachment and the tension bar. In later generators, these bushings were completely removed, and different protrusions were simply made on the front cover from above and below.


Install the rubber ring in the generator housing.


We fasten the diode panel with the winding with six screws.


We install the capacitor and terminals.


We insert the rotor with bearings, screw the front cover, pulley and impeller.
Finished result:

Generator




Part #1 - generator (12 31 1 288 409).

Now the generator has a much better look and condition.








Here, the difference in the size of the protrusion of the upper and lower bushings is clearly visible:


We install the lower bracket on the bracket, and the upper - on the tension bar. The tension bar is screwed to the cover pin.






The generator is installed. I will install and tighten the belt after installing all the pulleys.

Engine crankcase block


Again, I did not completely disassemble the engine block, so the photo shows only those parts that were removed.


Part #1 - cylinder block with pistons (11 11 1278 921). There is no such number in ETK for some reason... strange.

Part #2 - bolt M10X75 (11 11 1 735 525). It was not filmed.
Part No. 3 - oil pressure sensor (12 61 1 710 509). I had a sensor installed under the restyling wiring connector, so I left it.

Part No. 5 - threaded fitting (11 11 2 140 435). On my unit, there is no place for its installation, just like the fitting itself. Maybe it depends on the year of release...
Part No. 6 - centering sleeve D=12.5MM (11 11 1 280 594) - 2 pcs. It was not filmed.
Part No. 7 - threaded plug AM14X1.5 (07 11 9 919 228) - 1 pc. Plug for draining antifreeze from the engine block.

Part No. 38 - a set of gaskets. It was not filmed.

The bearing cap (#25) is simply pulled up, using a screwdriver or a flat blade. I had it with an old sealing ring. I bought a 42x3 mm ring, but I guess I need to take a little smaller, somewhere 41x3, or maybe even 40x3, so that it fits more tightly on the lid. We put the ring on the cover with the bearing.


We insert the cover and tightly drive it into the engine block until it stops. We fix it from above with a bracket with a bolt.


We put the tube (#11) with washer, spring and rubber rings. I have not put the spring yet, because it is pressed by the intake manifold.
Screw the fitting (No. 28) with an aluminum ring (No. 14).
Install the shield (No. 17) on the bushings (No. 19).
We fasten with bolts (No. 32, No. 33) the stiffness insert through the rubber gasket (No. 29).





We twist the threaded plug (No. 7) through the aluminum ring (No. 8) for draining the antifreeze from the engine block.
We screw the oil pressure sensor (No. 3) through the aluminum ring (No. 14).


That's all for the block.
I skip all other sections on the piston system, since everything necessary there was replaced earlier.












Next, probably a little about attachments...

Collection_136. ETK_11_Engine. Lubricating system oil filter. Oil dipstick

BMW E30 cars with the M20B25 engine were equipped with an oil cooler as standard. To install its hoses on the engine block, a special oil filter adapter with a built-in thermostat is installed.

Lubrication system oil filter




Part #1 - oil filter (11 42 1 707 779). I always use the Mann-Filter (W71915).
Part No. 2 - ring of round section 65X3 (11 42 1 265 670) - 1 pc. Rubber ring.
Part #3 - PUROLATOR oil filter adapter (11 42 1 711 070). Comes complete with built-in thermostat and spring.

Part No. 4 - ring of round section 20.0X3 (11 42 1 714 764) - 1 pc. Rubber ring installed on the bolt (#6). But it is not round, but flat, and flush with the surface of the bolt. At the same time, the bolt goes in quite tightly. And with a round ring, it may not fit at all... Therefore, although I bought such a similar ring, I decided to leave the old original one. If someone changed it, write what it is in the original.
Part No. 5 - sealing ring A27X32-AL (07 11 9 963 441) - 1 pc. Aluminum.
Part No. 5 - sealing ring A24X29-AL (07 11 9 963 384) - 1 pc. Aluminum. It is not clear what this ring is for. Its size does not fit anywhere and it was not installed there. Perhaps this is another error in ETK. If anyone knows for sure, please write.
Part No. 6 - PUROLATOR hollow bolt (11 42 1 711 071) - 1 pc.

Part No. 7 - set of gaskets (11 42 9 059 338) - 1 pc. The set consists of a rubber sealing ring 24.5x3 mm, an aluminum plug, and a metal retaining ring. I don't understand why it is not possible to order the original rubber ring separately, but only together with the plug and retaining ring? Why change the plug? Therefore, I bought a similar rubber ring 24x3 mm separately, although the old one was normal.


Assembly is simple - insert the thermostat and spring into the adapter.


We put the rubber ring on the plug, insert the plug, compress the spring with it and put the locking ring in the groove. Then we put an aluminum sealing ring on the bolt and insert it into the adapter. We insert a large rubber ring into the groove of the adapter. The adapter is assembled.


We bolt the adapter to the engine block in place of the oil filter in this position. Screw the oil filter to the adapter.


After installing the motor, we screw the hoses of the already installed oil cooler to the adapter.

ETK has another type of oil filter:
Environmental oil filter


I have never met him on an E30. If someone has such a filter, I would be grateful for a photo. I wonder what he looks like. Probably something similar to the filter on the M50 engines...

I skip the other sections on the lubrication system, as they relate to the "innards" of the engine.




As I have already said, during its repair there, everything that was necessary was already replaced.

The next section of ETK
Oil dipstick




Part #1 - oil dipstick L=533.5MM (11 43 1 718 863).
Part #2 - guide pipe (11 11 1 705 786).
Part #3 - bracket (11 43 1 720 566).
Part No. 4 - bolt M6X12 (07 11 9 905 524) - 1 pc.
Part No. 5 - clamp (11 43 1 258 342).
Part No. 6 - M6 nut (07 11 9 905 543) - 2 pcs.


It is important to use the dipstick that matches the motor, as they have different lengths and oil level markings.
The tube is tightly inserted into the engine block. A collar is put on the tube from above, to which the bracket is screwed with a bolt and a nut. The bracket is fixed with a nut and washer to the stud on the intake manifold. Since the collector is not yet installed, I did not install the tube bracket either. So far, I just tried it on in approximately this position.


Next, about the details of the engine block.

[The_Glory]

Collection_135. ETK_11_Engine. Timing belt. Housing of the timing unit

Timing belt




As I said earlier, the motor will not be disassembled, as it was recently repaired, so now only the belt and roller are replaced. And that - more for prevention and beauty.
Part #1 - toothed belt Z=127 (11 31 1 713 361). There are two types - with 127 and 128 teeth. In my case, it is a Continental CT520 belt with 127 teeth.

Parts No. 2...No. 15 - gears of the gas distribution mechanism. I simply cleaned and painted them without removing them.
Part No. 16 - tension roller (11 31 1 711 154). There are two types - for a belt with 127 and 128 teeth. In my case, this is the INA 531000110 roller for a 127 tooth belt.

It is important that the roller corresponds to the number of teeth of the belt! The number of teeth is indicated on it.

Part No. 17 - screw (11 31 1 272 433) - 1 pc. Pin for fixing the roller.
Part No. 18 - spring (11 31 1 267 746) - 1 pc. Belt tensioning mechanism.
Part No. 19 - pin (11 31 1 280 960) - 1 pc. Belt tensioning mechanism.
Part No. 20 - bolt M8X20 (07 11 9 915 093) - 1 pc. Belt tensioning mechanism.
Part No. 21 - timing belt replacement sticker (11 31 1 739 073) - 1 pc. I will glue all the factory stickers after the assembly is completed. For now, I will stick the sticker that came with the belt.

We screw the roller to the block with a pin, but do not tighten it. We insert a pin with a spring and compress it as much as possible. In this position, we fix the roller with a bolt.


When installing the toothed belt, it is very important to correctly set the gears of the crankshaft and camshaft according to the factory marks!
The lower mark - the line on the crankshaft flange must coincide with the notch on the lower cover.


The upper mark - the arrow on the camshaft gear must coincide with the line on the cylinder head.


We set both labels and in this position put the belt on the gear. Then we release the bolt of the roller so that it tightens the belt. We make two complete revolutions of the crankshaft, and check whether the marks have not gone astray.






If the marks are in place, tighten the bolt and roller pin. The belt is installed. Pistons with valves do not meet! :)


The Continental sticker is a great size for this pad. Then I will write the departure date in it ;)


Next, we install the belt covers.
Timing unit housing lower




I did not remove this cover, I just cleaned and painted it.
Part #1 - cover (11 14 1 272 390)
Part #2 - centering sleeve D=10.5MM (11 12 1 726 238) - 2 pcs. I bought these bushings, but they did not help.
Part No. 3 - elastic washer B8 (07 11 9 932 095) - 2 pcs.
Part #4 - bolt M8X22 (07 11 9 913 652) - 2 pcs.
Parts No. 5...No. 9 - oil seals and gaskets were changed during engine repair.

Cylinder block / additional elements

The oil seal and gasket of the rear cover were changed during engine repair.

Timing block housing upper




Part No. 1 - shield upper part (11 14 1 714 863) - 1 pc. There are several types, depending on the year of production. But it has the same number. It is distinguished by the presence of a fastener for a plastic wiring shield and a fastener for a metal tube of the cooling system.
Part #2 - shield lower part (11 14 1 271 862) - 1 pc. There are several types, depending on the year of production. It is distinguished by the presence of a fastener for a crankshaft position sensor. In my case, it is earlier, so the mount for the sensor is not used on it.
Part #3 - bolt M6X22 (07 11 9 904 505) - 1 pc.
Part No. 4 - elastic washer B6 (07 11 9 932 099) - 2 pcs.
Part No. 5 - bolt M6X55 - 1 pc. Here in EKT there is some error. No. 5 is not specified, and instead, No. 6 (07 11 9 912 351) M6X60 is specified. I don't know why, but it turned out to be long for me and did not twist all the way. So I shortened it to 55mm.
Part No. 6 - bolt M8X25 (07 11 9 913 653) - 3 pcs.
Part No. 7 - elastic washer B8 (07 11 9 932 095) - 2 pcs.
Part No. 8 - rubber gasket (11 14 1 269 557) - 1 pc. Rubber protective shield.
Part #9 - not used.
Part No. 10 - hook (11 14 1 706 959) - 1 pc.

Part No. 11 - crankshaft position sensor (12 52 1 279 695) - 1pc. I will write about it later separately in the appropriate section.
Part No. 12 - bracket (11 14 1 713 173) - 1 pc. Crankshaft position sensor bracket.
Item No. 13 is not used.
Part No. 14 - bracket (11 14 1 716 134) - 2 pcs. Plastic shield bracket for sensor wiring.

Part No. 15 - shield (11 14 1 716 133) - 1 pc. Shield for sensor wiring.
Part No. 17 - centering sleeve D=10.5MM (11 12 1 726 238) - 1 pc.
Part No. 18 - centering sleeve D=8.5X13MM (11 12 1 726 244) - 1 pc.

For some reason, I didn't have bushing No. 17 - a hook is attached to it for lifting the motor, so for safety, of course, these bushings should be there. Installed


Now the hook will hold more securely on the bushings.


First screw the lower cover, then the upper one. By the way, the M8 nut that fixes both covers is not specified in the ETK. It is not necessary to tighten it - later, a light bar of the generator will be attached there.


We insert the plastic brackets of the shield into the upper cover, and snap the shield into them, laying the sensor wire under it. The sensor is installed on a bracket screwed to the engine block.


A protective plastic spiral is put on the sensor wire so that it is not damaged by the pulley, but I will write about it in the appropriate section.


A protective rubber shield is placed on the back of the cover. The sensor wire is clamped on the shield.




All protective timing covers are installed.


Next, the oil filter adapter.

[The_Glory]

Collection_134. ETK_11_Engine. Water pump of the cooling system. Thermostat housing

So, we start the assembly with the water pump.
Cooling system water pump




My E30 had the entire cooling system installed from the E34. In my opinion, a radiator with a built-in expansion tank looks more aesthetically pleasing under the hood than a separate remote tank with its additional hoses. The early E30 tank, in general, looks somewhat archaic, and I have nowhere to install the late tank, because there is no bracket for its attachment on the body. Yes, there will be another tank there, but I will write about it in turn. So, I leave everything as it was. But there is one caveat - the pump was installed from before the restyling E30 (11 51 9 071 561), so there was no attachment for the metal tube of the cooling system. Therefore, I bought a new pump - already for the E30 restyling (11 51 9 070 758), so that everything was as it should be.

Part #1 - water pump (11 51 9 070 758). I bought an analogue from the manufacturer INA 538016310. The kit included a paper gasket.


Part No. 6 - sealing gasket (11 51 1 722 677). For some reason, I did not like the paper gasket, so I bought a higher quality gasket ELRING 774634
Part No. 10 - bolt M8X20 (07 11 9 903 039) - 3 pcs.
Part No. 11 - elastic washer B8 (07 11 9 932 095) - 3 pcs.
All other individual parts of the pump are no longer available.

For comparison: on the left - the pump before restyling, on the right - after restyling.




The only difference is the presence of a branch for the expansion tank, which I had previously blocked. Now, instead of it, there will be an "ear" for attaching the metal tube of the cooling system.
We wipe the surface of the block, and screw the pump through the gasket with three bolts.


The pump is installed.


Next, we install the thermostat housing with temperature sensors.
Cooling system thermostat housing




Part #1 - thermostat housing (11 53 1 730 470). I once wrote that there are several types of thermostat housings that differ in the number of holes for sensors, but according to ETK they all have the same number. Amazingly. I replaced the housing, it has two additional holes that are closed with threaded plugs.
Part #2 - M8 nut (11 61 1 713 432) - 2 pcs.
Part No. 3 - elastic washer B8 (07 11 9 932 095) - 2 pcs.
Part No. 4 - sealing gasket (11 53 1 722 692) - 1 pc. The price of the original gasket, in my opinion, is too high, and I did not find any analogues, so I cut it myself.


Part No. 5 - thermostat 80CEL (11 53 1 710 953)
Part No. 6 - ring of round section 60X3.5 (11 53 1 265 084) - 1 pc.
Part No. 7 - cover (11 53 1 265 059)
Part No. 8 - screw for removing air (11 53 1 275 881) - 1 pc.
Part No. 9 - bolt M6X25 (07 11 9 913 589) - 3 pcs.
Part No. 10 - elastic washer B6 (07 11 9 932 099) - 3 pcs.


Part No. 11 - sealing ring A14X18-AL (07 11 9 963 200) - 3 pcs. Aluminum 14mm.
Part No. 12 - temperature sensor 1-POL (12 62 1 710 512) - 1 pc.
Part No. 13 - temperature sensor 2-POL M12X1.5 (13 62 1 709 966) - 1 pc.
Part No. 14 - sealing ring A12X15.5 AL (07 11 9 963 130) - 1 pc. Aluminum 12 mm.
Detail No. 15, No. 16 - not used. Instead of them, 14mm threaded plugs are installed.


We screw in the sensors and plugs, install the thermostat and rubber ring, and assemble the thermostat housing.




We install the thermostat housing on the engine through the gasket. Just in case, I lubricated the gasket with sealant. And here again because of the damned Muscovites, they turned off the light!... I was screwing in the dark.


The thermostat is installed.




Then the belt and tags.

[The_Glory]

I haven't written anything in a while - there was no time, but the assembly of the motor is progressing little by little.
All spare parts have arrived, all parts are painted, fasteners are galvanized. The same process is going on, albeit rather slowly. Also because of the russian shit, there is no light in the garage more time than it is - this also significantly delays it.

Collection_133. ETK_11_Engine. Power unit

So, I'm starting the next season of the series! :)
Engine

Shortly before taking the car apart for restoration, I completely overhauled the engine. It is in good condition, and there were no complaints about its work. That is why I am not going to completely disassemble it. Purely "cosmetic" work will be carried out - cleaning, washing, painting and assembly, according to the ETK catalog.
Power unit


Although the engine is in good condition, its appearance is not very beautiful. :)






First of all, I removed the manual transmission - there will be separate entries about this. Then washing, cleaning and painting. I decided to paint with heat-resistant paint - I hope that it will hold up better than the usual paint from the previous repair. I will also use aluminum and zinc paints.


After cleaning, all numbers and markings became clearly visible. Everything corresponds to the BMW 325i model.


Including the engine number. By the way, there was an interesting story with him when I bought this car. When completing the documents, the expert looked for the engine number for a very long time, cleaned something there, wiped it, looked... but never found it. And in the end, he made a note - "the engine number is destroyed by corrosion"! :) It's not surprising - because he was looking for it on the large upper platform, not below! ))) After cleaning the lower little area, I finally found out my engine number just now! :)


As you can see, the number is somewhat unusual. I found numbers in this format only in the photo of the American E30. Amazingly. On European cars, the engine number is usually indicated in the following format:
256E
25 - 2.5 liters
6 - 6 cylinders
E - injector

I have simply indicated - 325i, and some numbers. If anyone knows what these numbers mean, I would be grateful for the information.

I'll brag a little about the entire crankcase! :) This is after many years of driving on our "wonderful" roads on a rigid static suspension with -60...80 mm lowering and no additional crankcase protection! ;)


I decided not to paint the crankcase and cylinder head, but simply washed it well and cleaned it mechanically with a brush.

Mechanical cleaning of the engine block.


Treated several times with a rust converter. Solvent washing and degreasing.


Painting in two layers with black heat-resistant paint, with hot drying.


The color is interesting, but too matte - it looks like a primer. Therefore, on top there is a layer of heat-resistant transparent varnish, with hot drying.


Everything is the same on the other side.








The gears are also cleaned and painted with zinc paint, the aluminum cover - with aluminum paint. As I said, I don't see any point in taking them apart - all gaskets and oil seals were replaced when the engine was repaired.


The flywheel is mechanically cleaned with a brush.


And the valve cover has not been painted yet.


I haven't decided yet whether to leave it black, or paint it silver, or at all, put another cover, not painted. Can it be painted in body color? what do you think :) In any case, I will probably paint it with powder paint together with the intake manifold - then I will decide on the color.







Looks good to me. ;)






Most of the parts are also already ready for assembly. It remains to buy some small things - gaskets, rubber rings, washers.


Hinged units are also almost completely ready.
Next time I will write about assembly.

[The_Glory]

Collection_132. ETK_03_Upgrades, accessories. Made from valuable wood species.

An option was available for the E30, which is more common on the more "luxurious" 5 and 7 series - S435 Made of valuable wood. On the E30, this option is not so common. Mainly on machines from ALPINA. Although, sometimes "aftermarket" retrofit kits were also installed there. But now we are talking about the original retrofit kit. This is really real wood, not vinyl decals! ;)

This is the ETK section Retrofitting, accessories

Fine wood finish




Item No. 1 - a set of torpedo linings
Detail No. 2 - an overlay on the torpedo console
Detail No. 3 - a set of overlays on the front door panels
Detail No. 4 - a set of overlays for the instrument panel
Detail No. 5 - overlay on the central panel
Detail No. 6 - cover on the box for small things

So, the complete set consists of seven overlays. In the previous entries about the installation of the torpedo, I have already mentioned some of them. At the moment, I have only two of them - an overlay on the box for small things, and an overlay on the light switch. The overlays are no longer available to order, they are very rare, so it is quite difficult to assemble the whole set. It's good that they were available in only one color - it simplifies the search at least a little. At a minimum, I still want to install an overlay under the instrument panel, but not the front door panels. I don't really like the overlay on the center panel. And the overlay on the torpedo console, in general, looks like a cheap Chinese vinyl sticker. Especially, if there are six buttons for power windows. Therefore, I will not install it. If I still can't find these pads, I'll try to make them to order.

In addition to this kit, a wooden gear lever handle was available.

Gear shift knob retrofitting, wood




Part No. 1 - retrofitting with a gearbox handle, walnut root tree (82 11 9 413 231). Wooden handle without top insert.

After the restyling, another wooden handle of the gearbox lever was available - 25 11 1 434 497. With an upper insert. This is the handle installed in my car.


Well, and for the completeness of the "wooden picture" :) - wooden "aftermarket" MOMO steering wheel.
So, my entire tree set.


All elements need restoration, but I will deal with this when the whole set is assembled. And for now, "we have what we have." (with)
I just renewed the paint on the steering wheel.








By the way, I have had a rare BBS steering wheel with a "carbon" insert lying around for a long time. I plan to convert the insert into a "tree". In the original, there is something similar to "aquaprint", so I will try to do it that way. The original sound signal button is missing, so I will try to make it myself - I have already made the blanks.


For now, I'll install what I have.
Helm.


There is still nothing to install the gearbox lever handle on. :) But there are still plans to "upgrade" it with lighting.

Overlay on the light switch.


Overlay on the box for small things.


General appearance.








A complete restored kit will look much better. ;)

P.S.
As it turned out, for diesel cars, plastic linings in the box for small things also have additional original sound insulation. So for the full effect, I removed them and added similar noise insulation there.






P.P.S.
If someone looked carefully at the photo, they noticed that the left front speaker trim and the headlight adjustment knob are missing. That's because I haven't installed the magnetic alarm lock on the driver's door yet. I will install it after painting along with other parts. This completes the interior assembly.


And then - a new season of this long series! :) Preparation and assembly of the motor.
I pulled it out to the middle of the garage so that it would be convenient to clean and wash it from all sides. After all, I will definitely not put it in this form! ;)






Then about the motor.

Sharp, I love !!

Collection_131. ETK_52_Seats. BMW sports seat.

Seats

In the cabin, everything is ready for installing the front seats.
A little general information about them.
Three front seat options were available for the E30: standard seats, BMW sports seats (Sportsitze), and RECARO sports seats.
In the M3 EVO, RECARO SR3 sports seats were installed, which had integrated head restraints, additional lateral support and the possibility of installing 4-point seat belts.
I will write about the seat in more detail, in the form of an FAQ:
In 2-door and 4-door sedans and touring cars, the front seats differ structurally only in the handles and the mechanism for folding the backrest forward, but, in principle, they are interchangeable. The handles and mechanism for folding the backrest forward can be installed on any seat.
The guides of the standard and sports seats are the same, but the RECARO sports seats have a different longitudinal adjustment lever design. There are two types of guides - before 85 and after 85.
I'm not sure, but I read somewhere that the guides on convertibles are higher than on sedans.
Rear and front headrests are the same (except front RECARO).
Front seat heating is different for standard and sports seats, and for fabric or leather upholstery.
The upholstery fabric texture sets were different for the 4-cylinder and 6-cylinder cars.

Depending on the year of production, the engine, the type of trim and the configuration of the car, the seats have many ETK numbers. Therefore, it makes no sense to indicate them.

So, now about my specific seats. At first, completely different seats were installed - the right one is standard, and the left one is from E36. Therefore, almost immediately, I completely replaced them with BMW sports seats (Sportsitze) from a 1992 car (probably from a touring car). I sewed them in black and installed heating. The seats are in very good condition, so there was no point in taking them apart to take pictures and put them back together! :)
So, here I will not describe everything in detail - just general photos - BMW sports seat (Sportsitze).

As I said above, the handles and forward recline mechanism from the 2-door sedan seats can be installed on the 4-door sedan seats. If there is such a need.
The details of fastening the front head restraints are similar to the rear ones. The headrests are simply inserted into the holes. Can be adjusted in height and inclination. I already wrote about them in the section on the back seat.

Rear and front head restraints are the same for standard and sport seats (except front RECARO).

The back panel of the backrest is attached from above with staples, and from below with two self-tapping screws.

Cladding by the meter




As I said above, depending on the year of manufacture, engine, and configuration of the car, the seats have many upholstery options with different ETK numbers. Therefore, it makes no sense to indicate them.
Fabric, faux leather, and genuine leather upholstery were available. The main colors are black, blue, green, brown, beige, gray, red. Before restyling, and after restyling, these colors had different shades and textures. The upholstery fabric texture sets were different for the 4-cylinder and 6-cylinder cars. There were also special skins for exclusive and individual configurations - M-Technic, Edition and others. On all E30s, the skin has longitudinal seams, except for convertibles, where the seams are transverse.
According to the VIN code, my car had PINIENGRUEN green cloth upholstery (0149) - for cars with 4-cylinder engines (316). But I bought a car with a different interior. The door panels were 0211 ANTHRAZIT, and the seats were re-stitched in a similar fabric. After replacing all the seats, I looked around for the 0211 ANTHRAZIT fabric that was available from 85 for the 6 cylinder engine - just what I needed for my current kit! I still found it and bought it, thanks to a friend.


But in fact, the color was not black, but brown... alas...


At that time, I could not find a black "crow's foot", so I decided to sew the seats simply in black, with transverse seams, like on convertibles. It also turned out very well. But the idea of making the entire interior in black "houndstooth" doesn't leave me... :) Yes, such a fabric is now on sale... I already have a back rest and four headrests in the original 0211 ANTHRAZIT fabric. Someday, maybe, I will have the whole salon "crow's foot" 0211 ANTHRAZIT. Or blue "crow's foot" 0212 PACIFIC - door trims are also already available ;)

The photo shows M TECHNIC decorative overlays (52 10 1 927 000) on the back.

For the E30, front seats were only available for the M3. But I also installed them - the interior looks much better with them! ;)We pierce the skin with them, and bend their spokes inside. One nuance - although I ordered them new, the color of the stickers on the driver's seat quickly began to fade... Therefore, I "laminated" them with a transparent adhesive film.

So, although the seats are in good condition, I still did some minimal "maintenance" of them - I cleaned and lubricated all the adjustment mechanisms, renewed the paint on the guides a little, and cleaned the trim.

BMW sports seat guides


There are two types of guides - before 85 and after 85. Structurally, they differ significantly, but they are interchangeable when attached to the body. Guides up to 85 are attached to the body with three nuts and one bolt at the back near the gearbox tunnel. Guide rails after 85 are attached to the body with two nuts at the front and two bolts at the back. In ETK, simple washers are used in one case, spring washers in another, or they are not used at all - the logic is not clear. Therefore, I prepared both simple washers and spring washers, but in fact I used only spring washers. I have a body of 84, and the guides of 92 - therefore fastening with three nuts and one bolt.


Plastic decorative caps for nuts also come in two types. Both types are no longer available to order. Earlier (before 85) are high, and later (after 85) are low. High caps are not suitable for guides after 85 - they interfere with the longitudinal adjustment of the seat. I had to order low caps for 3D printing.


I cleaned the guides, repainted a little and lubricated all the mechanisms with Teflon grease.




The photo shows the heating connector, which is fixed in a special plastic bracket on the spring frame of the seat. The connector of the driver's seat belt lock is also fixed in the same bracket.

All mechanisms work well, so I did not disassemble them - I just cleaned and lubricated them.

After that, for "prevention" I cleaned the cladding with a "tornado"


All that remains is to fasten the seat belt locks.


The early locks fit the late guides without a problem. The bolt was closed with a decorative cap.


The seats are now completely ready for installation.
We connect the seat heating connector and the driver's lock, if there is one. It is better to immediately raise the seat to the maximum height on the guides. We install the seat on the body studs and fasten.


Fasten the seat belt, cover the bolt with a decorative cap.


We also close the fastening nuts with caps.


We adjust the position of the seats - installed.






Now it remains only to fasten the steering wheel! :)
By the way, next time there will be the last entry on the assembly of the interior - about a rare option for the E30 - S435 Made of valuable wood species
