Re: Want to buy - for an earlier engine

I've found it best to search the part numbers on eBay. Most sellers involved with BMWs will provide these. You can then save your searches and have eBay email you when someone posts something that matches your search. Otherwise, the search results can be very noisy, as you're experiencing. eBay is a...

Re: Valvar 30A Relays // 1 364 986

I checked the fuse box and that's when I saw the green fuse. Wait a minute ... green? The aux fan is wired to the 25A fuse at position 17 ... 25A fuses are blue. At least new ones are. Decades-old ones turn green. And get all kinds of crap caked on them. And get loose. And turn 12.8V at 25A into 11....

Re: Valvar 30A Relays // 1 364 986

Lock, terminal 30 is actually 11.4 Volts, which isn't right. The battery is 12.8 V. If I shunt the black wire from the Stage 1 relay connector to the battery (+) the fan comes to life with authority. There's something happening, I suspect you're right and will trace the red/green wire. It looks to h...

Re: Automatic Transmissions?

I have no experience, but Andrew Everett's book on 5- and 6-series restoration says the Borg Warner 65 is "crude but super-reliable" and not expensive to rebuild. The 3HP22 is considered by him to be a better unit, and he recommends upgrading to it if you have a troubled BW 65 or older 3HP20 (used i...

Re: Valvar 30A Relays // 1 364 986

OK, I have a strange problem that I've isolated to the Stage I relay connector block. The relay tests good. If I use a voltmeter probe I pick up 12 volts between terminal 30 and ground, but if I plug in a jumper (or the relay) the voltage won't turn the fan. The aux fan runs on 12 volts supplied to ...

Jon, it's like you're reading my mind. I just came in from the garage utterly fed up with my light situation.

Re: 1976 BMW 530i "Eleanor" rebuild project

Mike, I've got block envy. It looks incredibly sweet - really nice work. But, seriously, how the hell are you going to move Eleanor when she's not even TKD-level disassembled? Are you a logistical genius, or have a photographic memory or something? I can't remember which screw goes where on a fully ...

Re: difficult or PITA bolts etc - for amusement!

Gary, that's a good one from the Land of Oz. It's about the same to get to the lower bolts on the #6 intake runner at the lower plenum on a LHD car for us Yanks. The brake booster makes it cozy, but a long extension and a u-joint are your friends there, too.

Re: difficult or PITA bolts etc - for amusement!

For anyone without the spin-on fan ... the fan. Need to access the front of the engine? Drain your rad and pull it out so you can take the fan off the flange. PITA, but any sane person will suffer this exactly once before upgrading. The hood is also a pretty major PITA to remount once off. Anyone as...

... getting a clear plastic container to contain fuel. Measure the flow at idle and under throttle.
If you do this, make sure it's a big container, as the pump delivery rate at spec is about 16 oz. per minute.

Re: Decreasing Fuel pressure/stall

I might start by jumping the fuel pump and seeing if that changes anything. There are two pins on the AFM connector that you can bridge to turn the pump always-on. If the symptom is resolved, then you can eliminate a restriction as the cause and focus on electrics. Besides the connections to the pum...

Re: Squeak in Rear Suspension

No, the diff mount is still original. It occurred to me that it might be on the table if I was unable to replace the subframe mounts without dropping the whole axle.

Re: Squeak in Rear Suspension

I replaced the shock mounts two weeks ago, which did not resolve the problem. That was vexing. Today I replaced the subframe mounts (hat tip Lock for spotting the issue) with Ireland Engineering urethane mounts. It really quieted things down and definitely improved the rear end. It was always a bit ...
