M62tu engine work

[Pinepig]

I made a thread about that (subframe removal) on bfc , ZERO usable info.

What do you expect out of BFC, I bet if you asked how to slam your car and what offfset wheels you need to run tiny tires that tuck up just right the topic would be on the first page for MONTHS.

Replaced both vanos solenoids today, the rear part on the old ones had a bunch of play/movement.



damn things aren't cheap either



removal with special tool



wanted to get a picture of the rear part



new vs old



installed upper pan/gasket and some of the accessories/brackets. lower pan, other engine mount/oil filter housing tomorrow and then i'll hang it on the same scales I used before with m10/m30 swap





New pressure plate bolts are on, new clutch kit waiting to be installed along with engine/tranny mounts. Fuel injectors in the mail, sent them off for rebuild.

[Jean]

Clutch installed, new plugs installed. Each spark plug boot cleaned and checked for 1.8k resistance.

AS IS w/o a/c compressor and starter but with the 38lbs flywheel + clutch kit mounted this tips the scales at 450lbs.

My m30b35 with single mass flywheel/g260/6 and starter was just under 540lbs on the same scale.

So, a good chance that m60/m62 with lighter flywheel w/o ac compressor will not add any weight to my car.

I'll weight the m62tu + tranny next weekend with starter, and will eventually do the same with the v8 for my e30.




stock heavy flywheel + new clutch kit

I guess we can dispel the talk of these motors being fat!

[Jean]

Items left -

New o-ring for the alternator
New bolts for the lower oil pan
New exhaust manifold studs

Engine oil filter
Engine oil
Tranny oil
Clutch/Brake fluid
Install rebuilt fuel injectors
Install fuel rail and wiring.

Grab the short shifter kit

Stuff it all in the car hopefully next weekend

Yup, I'm glad you weighed it Jean! Given the fact I had moved several different motors around at different points in time, albeit without weighing them, I knew the M60/62 was not heavier than an M30, maybe not heavier than an M20. Plus, it's shorter in length. With a lightweight flywheel and no AC compressor, the 460lb figure that has been thrown around seems pretty accurate. Should be perfect in our E30s!:D:D:D

Np! I'll do the m60 one in more detail....bare long block first, then complete , then with tranny. I'll get the weight of the car after the swap as well to compare with the previous weight too.

[BruceBe]

I have it written down somewhere, but I believe the weight difference between the departing S52US and M60 going into our e30 was about 30 lbs in favor of the S52 (S52 was lighter). Don't drop one of these starters on your foot. I've been thinking about developing a compatible mini-starter for these engines. The vehicle could probably lose 15lbs in starter alone.

[Jean]

Bruce, what flywheels were used on the s52 and m60? The one on m62tu is almost 40lb before clutch kit is added!

Also, how did you install the m60 in your e30, from the top with or w/o the transmission/manifolds? I was hoping to do it from the bottom, but learned it won't clear the chassis that way.

[BruceBe]

The S52 had a JB Racing flywheel and Clutchmasters organic kit. Donor M60 had an auto transmission flex plate when weighed.

I R&R the engine without the trans, and without manifolds, from the top. The upper bell-housing bolts are the biggest PITA. I solved that problem with a Snap-On internal torx box-end wrench.

That is the bonus of this motor in the E30 chassis... the flatter firewall allows access to these bolts from the top... Gearwrench makes an internal set as well, that's what I have. It's a good solution, though, no matter what the brand...

Garey

[Jean]

Alright, engine is in. Goes in from the top w/o manifolds, then you raise it up 25mm or so and do the manifolds (pita, but doable).

Waiting to get in the car



Did not want to deal with dropping the subframe on this, too many things to deal with vs. e30 subframe.



down it goes



in



exhaust manifolds added



yay

[Jean]

Left to do:

Install new short shifter/hardware - done
Install radiator/hoses - done
Install/mount the a/c compressor - done

Replace tranny fluid
Install the 6 tranny and new slave cyl.
Repair or replace res to ps pump power steering fluid line
Install engine harness and rebuilt fuel injectors.
Add oil/coolant/ps/brake fluids.

Much easier with both manifolds off ;) I usually throw them on though before i finally set it down though..

Got a 4.4 setting on the bench at work for my e34 touring. It'll be sleeve and have m60 timing chain set up, obdI. Only want the motor apart once... While you got this apart you should do the bosch design III 19lb injector upgrade :)

Its a shame the m62b44 is kinda a shitty motor, due to the timing chains guides...

I couldn't believe what I was looking at when he popped the front timing cover off, WTF were they thinking when they pulled that big U shaped guide out of their ass.
Stupidest piece of German engineering I've ever seen.
