    5k is on the cheap side, are they spraying the jambs or taping them. Engine bay?

      Spraying jambs and engine bay. Keep in mind that price is if I do all the engine removal, etc and deliver to them as a rolling shell. Tack on $3000 if I drove over and tossed them the keys.

        Saturday update. On the list:

        Top off coolant and replace spark plugs (stayed with Bosch because i had trouble finding terminal caps for the NGKs I got). Took 5 mins. MUCH easier than in my 335

        Diagnose low voltage issue. My wipers had been very slow, as had my sun roof. My radio would light up but not turn on, and my horn sounded really weak. It seemed like low voltage everywhere...

        Car off...


        Car on... There's the problem


        Car on, AC maxed


        The grounds all looked good, so I pulled the alternator





        The tall brush is about 8mm, short one is about 6. Seems like a good candidate for low voltage. I ordered another voltage regulator from BMA Parts for $30 (part 704 54004 101). Not sure if it will fit but they had it listed under the E30 M3 and it is a Bosch part. Better than the $120 ECS had on theirs.

        Also checked out what used to be the alt bushings.

        Old vs new



        Replaced exhaust hanger





        Pulled the old power steering and AC belt, both are showing cracks. Going to clean up a bit tomorrow before reinstalling belts.

          New M3 Owner...How'd I do?



          Replaced the voltage regulator but I'm still getting 11v when running (at the battery and off the alt under the hood). Looking like a new alternator is in order. Anyone have a recommendation?

            How's the alt ground? Did you make sure to accelerate the engine to "excite" the alternator so it can begin charging?

              Barry is right - if you don't rev the engine after starting to turn off the charging lights on the dashboard it won't charge at proper voltage...
              Below the radar...

                Alt ground looked good. Good advice on revving. I'll try it soon. Working on wheel bearing #2 now. Amazing what some experience, the right tools, and a good workbench can do for efficiency. This took an hour tonight vs 10 days last time.

                  Weekend Update...

                  So I tried revving before and during reading the alternator (from the alt, not battery). I got 13v immediately after the rev but it then fell to 12.75 and 12.5. During rev it gets over 13 but I didn't see 14. Thinking it needs to be replaced.

                  Also, I nearly finished the other wheel bearing. The job is so much easier the second time with the right tools. My best advice is make sure you have the right tools. Get a bearing puller set on loan from an auto store or buy from Harbor Freight or another store. Don't screw around with the YouTube methods of big washers, PVC pipes, etc. Also a slide hammer works wonders for removing the hub.

                  While I had the shocks disconnected, I thought I would take a shot at those squeaky shock tower mounts

                  Take em out







                  New v. old



                  someone hypothesized they were blown out...they were correct



                  In the process of getting these things off, I seem to have flattened the threads on the shocks themselves...



                  They were probably blown out anyways







                  So current status:

                  - Need suggestions for shocks. Thinking about staying stock, any thoughts?

                  - Alternator is on the grocery list

                  - going to do diff fluid change while I'm at it

                      I've read a few places where people said Billys were too stiff. I think I'll stay with the stock springs because I dont think i want to drop the car because I'm scared of cracking the oil pan.

                        Decided to stay stock for the sake of originality and to keep myself from diving down the rabbit tunnel that is suspension modification. I figure there's enough to do on the car that the money would be better used elsewhere. So, 2 Sachs shocks and 1 alternator are in the mail!

                        While waiting, I decided to pull that awful radio out of the car. It was an eyesore, time to go. As I suspected, the install by a previous owner (our favorite zip tie aficionado) was a total hack job. Electrical tape and lots of it




                        And underneath the tape, professional level wire splicing...









                        Banished



                        This hole looks so much better than that radio

                            New M3 Owner...How'd I do?

                            I'm on vacation this week so finally have some time to post an update!

                            Time to get rid of those busted old shock tower mounts!







                            And new rear shocks






















                            Remanufactured alternator



                            Bingo




                            Working on removing the cosmoline from the engine bay. 50/50 mix of boiled linseed oil and mineral sprits + patience an elbow grease











                            ^ this is also the pic that shows the pool noodle in my engine bay. I would love to meet the owner who did this (i imagine its our zip tie fan).

                            I don't have a pic but I also discovered that time and heat had gifted my car a supplemental air intake in the form of a 3 inch tear in the intake elbow. Glad I discovered it before a leaf, bug, or other foreign object did. The new elbow has arrived and the pool noodle replacement gasket is on the way.

                            Now a question, several of the lines behind the engine are zip tied to each other, and two of the fuel lines are zip tied to hang from the brake line. Why in the world would anyone do this??? Any ideas? I'm inclined to just cut the zip ties off. Is it missing a bracket that the hoses are supposed to run through?





                            Up next...

                            Radio upgrade from this...


                            To this...


                            Throttle zip tie lattice delete...





                            And to replace the dry rotted wire wrapping with some fresh oem tape



                            No shortage of projects here! Should be fun.

                              I hope that linseed/paint thinner combo worked. I didnt intend for it to remove cosmoline but its possible with patience like you said.

                              Plan to use the stock amp?

                                It worked well. Still a lot of areas to cover. It will be easier to clean parts as I disassemble areas for various repairs.

                                Yes planning to use the stock amp, wiring, speakers, etc. I'm a total novice at car audio so I'll doubtless be researching and asking questions on here. I'll document thoroughly so that other stereo noobs like me can do the rmt200 install without any trouble. After a lot of looking I think its the best looks/function combo out there. Bluetooth streaming in an 80s car is going to be awesome.
