Re: Where's the best place to buy.....

I used to frequent BMP, then BavAuto for common maintenance stuff. They're now both extinct. I agree with Mike on Autohaus AZ and RockAuto for common stuff. You might also check Pelican Parts (well liked by E28 guys I know) and ECS Tuning. ECS sort of paired up with BavAuto as BavAuto closed and wer...

Re: Swapping combo relay from a 76 530i to a 77 530i ?

I think it would work, but that's a guess. I suspect the black plastic case is more an indicator of much more recent manufacturing than a different part and possibly also a part number supercede to explain that difference too. I can tell you my 77 530i originally had a metal case combo relay too. It...

Re: No click or fuel pump hum when AFM flap is opened?

I also like to jump pins 36 and 39 on the AFM. That bypasses the AFM flap fuel cutoff and you can
test fuel pump operation without starting car. Pump will run with ignition in "ON" position before cranking. Combo relay is certainly a common culprit for your problem, as discussed.

Re: Strange Stall/ No Start - Overheated coil?

Hey, Tom. Yeah, that's the ICU box. It should have transistors inside - that and the ECU is about
as sophisticated as electronics were in the late 70s. I can take a look in my factory manual this weekend. I've also got a Haynes manual I need to fish out.

Re: Strange Stall/ No Start - Overheated coil?

I was about to suggest the ignition control unit (ICU) for the transistorized ignition as Mike W is describing. Having seen your car, I know you've got the old school distributor. Next question is whether your distributor has the inductive pickups or the points/condensor. If you have the inductive p...

Re: E28 drive shaft compatibility

When I put the Getrag 260/6 I found that the e28 driveshafts had a different profile to the e12, basically the e12 gets narrower before the center bearing where the e28 does not. So the e28 driveshaft might hit that area. You can kind of see it in my picture below, if the driveshaft keeps going for...

Re: E28 drive shaft compatibility

Thanks for the responses. I am aware there are a lot of parts that look identical, yet have different part numbers. There are a bunch of parts for the 528i that are the same, but lighter/thinner, than the 530i. Given how rare all these parts are getting, I'll just error on the side of grabbing the E...

Re: E28 drive shaft compatibility

An 85 e28 and a 80/81 e12 have different part numbers so likely not a direct fit. Driveshafts can be professionally shortened though. I would think there are plenty of used ones out there. You’ll need the correct bell housing for the analog speedo drive if you don’t already have it. Yeah, my though...

E28 drive shaft compatibility

If one obtains the Getrag 265/6 5-speed from an 85 535i, is that drive shaft compatible in the E12? I did some homework in the FAQs. Realoem seems to suggest the E24 of all years is a safer bet on the 5-speed driveshaft. The knowledge from owners of multiple BMWs is invaluable on interchange questio...

Re: Dexron II ATF

Your signature says 5-speed, so I assume you're just talking about power steering. I'm just running the current Dex/Merc as you mentioned for P/S fluid with no problems.

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.

Re: Windscreen washer tubing

I replaced all of mine about 4 years ago with translucent silicone tubing. It should remain flexible longer and not yellow. The braided stuff is a higher-pressure version of regular vinyl tubing, as I recall. This isn't a high pressure application, so lots of choices. Even the silicone stuff can be ...

I spent years working on making my 77 530i run cooler. I've conquered most of those demons and have done just about everything listed in the FAQ.

Re: Hesitating and Lurching

I think you got it. I had a bad gas experience last year from just a 4 gallon top off . It took 5 or so tanks of premium and a can of Berryman's B12 Chemtool on almost every one to apparently clear the problem. I had a drain plug present on the tank added years ago, but considering this occurred on ...
