Re: 1976 BMW 530i "Eleanor" rebuild project

Parts look great.

Is that a case of Drumstick Sundae Cones I see back there?

Re: 1975 BMW 530i - Clunking Noise from Front Right

You've probably done this, but because you mention that the struts were replaced, check that the mounting studs are tightened to spec at the shock tower and the self-locking nut on the strut insert piston rod under the dust cap is tightened to spec.

Re: 1975 BMW 530i - Clunking Noise from Front Right

My strut mounts were replaced while replacing the strut inserts, so the springs were compressed. Recently while having some rust repair done on the wheel house, my body man unbolted the strut mount bolts from the strut tower while the car was on a lift and the strut lowered enough to clear the strut...

Re: 1975 BMW 530i - Clunking Noise from Front Right

Just a note that if you need to replace your strut mounts, the E12 front strut mount (part no. 31331101663) is identical to Part 31331106060 for the 2.5CS-3.0 CSL (04/1971 — 11/1975) and the 2500-3.3Li (08/1968 — 02/1977) with the exception of the length of the locator bolts. The 6060 part is much c...

Thanks Mike, very kind words. Here's the accumulator and thermostat housing in place.

Re: Vapor Blasting

Here are the E21 runners mounted. https://i.ibb.co/ZKMZPGQ/826-D188-E-196-B-4-E16-8-F79-A11507-DBF974-1-105-c.jpg The fuel rail was painted with Master Series urethane-based coating. The color is a close match to the vapor-blasted aluminum. There is a black topcoat available as well, which I've move...

Re: Intermittent no-start with 635 Motronic 1.0

That's interesting, and a good question - I don't think I've had the no-start on a fully charged battery. But I have had a case where it wouldn't start, I was troubleshooting for awhile (not doing anything to the battery), and then tried again and it started right up. So it's inconsistent. It takes...

Re: Intermittent no-start with 635 Motronic 1.0

Sorry, Dan I should have read your post more carefully. I think you've properly narrowed in on the spark as the culprit. I did have a strong-crank no-start situation that was due to a partially discharged battery. Once charged, it started right up. So I think Karl might be on the right track. Have y...

Re: Intermittent no-start with 635 Motronic 1.0

Have you eliminated the injectors as a source of the problem? A spark tester will allow you to verify is spark is the problem or not.

Re: Valvar 30A Relays // 1 364 986

I found them in the Haynes US-spec 528 schematics labelled as "Stage I" and "Stage II" relays. They control the A/C compressor and the aux fan via the various temp switches.

Valvar 30A Relays // 1 364 986

I've tried to armchair sleuth this out, but I'm finding the answer elusive. I have two relays sitting side-by-side on top of my battery. They are these: https://i.ibb.co/Q8pyZ6p/relay.jpg 12V, 30A, Valvar type 230006, marked with part number 1 364 986. This is referenced on E28 boards as a "relief r...

Re: 1976 BMW 530i "Eleanor" rebuild project

Ditto to Robert's experience with glass-bead or vapor blasting. My log and thermostat housing are on their way to a shop now, after having the valve cover and runners vapor blasted last year. An alleged benefit is that many of the small surface irregularities of the sand castings are peened closed, ...

Electrolysis á la Keenh

So, this is not an informative post, but rather one expressing amazement and appreciation. I wish I had taken "before" pictures of these AC Condenser brackets. They were crusty with rust, one of the washers had rust-welded itself to the bracket -- they were utterly irredeemable and I was sizing up o...

Re: e12 temperature question

Any performance problems that you've noticed? It might be your gauge is bad, but if this were me I'd replace the thermostat next. Another cheap part and easier to do than opening the dash even though still a pain. Temp gauges don't fail that often, but it has been known to happen. If you didn't do a...
