Re: e28 power seats?

The e34 seat foam is molded to humans, unlike the virtually flat e12 so that was a surprising difference. Pity they don't fit directly into my '79 chassis, but apparently the 80+. The E34 comfort seat was shared with the E32 and also had heating available. Once you crack into the E32 option list, y...

Re: 1980 528i “Lucky Find” Project

Your car is missing foam sound insulation which would prevent metal-to-metal contact. I'm not sure it's normal for there to be contact, though, even without the insulation. It could be that the mounting bracket is bent causing the rubbing edge of the airbox to ride too high. When you take it all apa...

Re: 1980 528i “Lucky Find” Project

How long since this has been started? Here are some pointers from Dr. Siegal. https://www.hagerty.com/media/maintenance-and-tech/dont-cold-start-a-long-dead-car/ In your second photo, think the snorkel just came off the airbox and the ignition wires spread into the gap. I can't quite make out what's...

Re: Valve clearance gap?

I use a ZDDP additive and Valvoline VR1, which is high in zinc and phosphorous. The VR1 product sheet specifically says it's not for use in cars with catalytic converters. But the story is a little more complicated than that. Cats have been on US cars since 1975, and before the early 2000's, all oil...

Re: C-pillar Vent Rehab

For posterity - unfortunately the adhesive pinstripe method didn't stand the test of time. The extreme bends required at the ends of the vanes were a problem for the metallic stripe, which crumpled and admitted water behind it, leading to a loss of adhesion. I resorted to using a dense foam roller a...

Mike, did the car use the E28 e-brake console, or was the switch block mounted somewhere else?

Re: e28 power seats?

This thread might be helpful. If you can find an E28 wiring diagram, that will show you the basic layout. From there it's just plumbing, but using OEM harnesses will certainly make life a little easier. I think that the E28 e-brake console where the switches live will physically fit in an E12, but I...

Re: Aux Fan Bearing Lube

All of the external wiring of the aux fan checked out okay. Fan was drawing under 22 amps. But removing the wire from the underside of the number 17 fuse showed how toasty things got below deck: https://i.ibb.co/VBYR7CP/Melty.jpg I was surprised that both of the red/green wires heading to the Stage ...

Re: 1976 BMW 530i "Eleanor" rebuild project

Nice to hear from you Mike. I suspect the next update will report that the new garage is built, complete with geothermal climate control and a new hand-built two-post lift made from parts sourced from Craigslist, office liquidators and Harbor Freight. Hope you're settling in well.

Re: alternator bushing

I haven't tried this to re-seat the AC belt, but once again citing to the ever-resourceful Lock, he said he used a 1=1/2" C-clamp on the AC pulley to hold the AC belt in the groove to start it, and then rotated the engine to thread it into place. My solutions were far less elegant, relying on a pair...

I didn't know that, as I replaced my water pump at the same time as the flange and the fan/clutch. I'm glad I did now.

Re: viscous fan - how it works + options

Gary - You're probably asking the exact wrong guy, because I'm so OCD about stuff like this, I would remedy it just because it would irk me. As I'm talking to a guy that spent upwards of 10 hours on his back steam cleaning the underside of his E12, we may have something in common in this regard. :D ...

Re: viscous fan - how it works + options

Hi Gary - yes, the water pump pulley bolt pattern is different for the spin-on fan clutch flange. You want the flange (p/n 11511277387) and the matching pulley (p/n 11511271423): https://www.realoem.com/bmw/enUS/showparts?id=3995-USA-04-1981-E12-BMW-528i&diagId=11_3057#11511271423 I got mine from Fa...

Re: No start...looks like no power to fuel pump?

As Robert Bondi pointed out on another thread, the '77 did not have an in-tank lifting pump. This correction posted for posterity.

Re: Aux Fan Bearing Lube

That's a good idea, Mike. I assumed that if the fuse wasn't popping the draw was under the fuse rating. I'm thinking I'll measure at the connector, but I'll need an ammeter with a higher rating than 10A. I have made sure the prong has plenty of tension. I have not taken the fuse box apart to peer in...
