Re: Strange Stall/ No Start - Overheated coil?

BMW did some transitional things on early 635s, but since you said L jet it should have a conventional distributor, correct? In that case the ECU only gets a signal from the dist to fire the injectors, it has no role in spark. However there is a control unit for the ignition which has been know to f...

Re: Strange Stall/ No Start - Overheated coil?

Check the ballast resistors and wiring to them. If it's getting a full 12V when it should only be getting 6V (or whatever, I don't know the spec) it could lead to an overheated coil. Not on BMWs, but I've heard of that happening on other cars.

Re: now it's the starter....

Its easy peas to get the starter out if you ask me. Go check the tool box in the trunk, the bent wrench you are after is in there. Its two nuts on the starter to get it out, that wrench will reach both. sure its tight, and you can only get maybe a 1/4 turn each time, but once the nuts are started o...

Re: starts - won't run unless key held

You need to host the pic somewhere else like https://imgur.com/ Sounds like you need a new ignition switch though. It comes out, you might think it doesn't, but it does, just a tight fit. Originally there was a little tiny slotted screw with paint on it that held it in place. Somewhere between cheap...

Re: I know of an 86 M car that was raced and parked years ago

What engine is it? A ///M out of an M5 or M6? It should fit then but the motor mount bolts might not be in the right place. When I put an '80 engine in my E28 I had to fab new motor mount brackets, it had holes in different places. Took me longer than I thought it would, mostly in design which was o...

Re: E28 drive shaft compatibility

Yep, different part numbers can be the same, close enough or completely different. On driveshafts in particular the 3HP22 shaft being close enough to work in a 265/6 application.

Re: ANOTHER injector leaking

You're lucky it's leaking there and not at the body itself, I've run into many of those. But yes, you can emphatically put a hose clamp on it. The fuel line today, even BMW line, isn't what it was way back then. I'm not sure it was any better or longer lasting, but the old stuff was incredibly tough...

Re: Electronic Control Unit (ECU) harness compatibility

79 used a different ECU than 80-81 but they're fully interchangeable. IIRC the difference is there is a different trigger when it transitions from open loop to closed loop in the warm up phase. 79 E24s however are different, both harness and ECU, they didn't go to an O2 sensor until 80, unlike E12s ...

Re: E28 drive shaft compatibility

I've only had one dealing with Mesa Performance but it was good, Jim seemed like a good and knowledgeable guy. I should know the answer but I don't. I do know according to Realoem an 85 G265 shaft should be 1522MM, however I don't know how and where they measure them from. I've got a couple of drive...

Re: Lube AC Blower Motor?

A zoom spout oiler might be the best way to try to do it. With the extendable tube you might be able to get some oil in there to the bearings. Look for it at a hardware store or good auto parts store.

Trip ODO repairs

Nothing here is meant as a slight to Jeff or odometergears.com, he's a good guy and from all I hear produces an excellent product. But sometimes you just want to repair what's there and can. I first did this on my first E21 when it didn't work with a mere 197K on it. I repaired the gear and last I s...

Re: HELP with Blower Fan Dial

Ironically I just dug into mine today. To me the PITA is getting to it, pretty much removing the console to do it. Doing it over a dishpan or something isn't a bad idea, but I didn't really have too many problems, the grease was so sticky everything stayed in place. There is only one ball bearing an...

Re: Driver's floor pan rust and carpet dyeing

You might also check the availability of carpet for the E28. Seems like I recall reading some posts where E28 carpet was swapped into the E12. Mid sections of the two cars are very similar. True, I've got an 85 E28 carpet in my 80 528i. Not perfect, but it does indeed fit. 79 and earlier cars would...

Re: Driver's floor pan rust and carpet dyeing

There are aerosol coatings that might work where dyes don't. I have no experience with them but a company called SEM makes one. SEM products are generally very good. I haven't done it on carpet that gets used regularly, but I have used it on the package shelf which I believe is the same carpeting, ...
