Re: Fuel/air mixture adjustments

There is a remarkably good tool that came with the car for measuring this exact thing. The Oxygen sensor. If all is well, once warmed up just a little bit, it will show an output, measured while in line and connected, of about a half a volt, bouncing up and down constantly. Technically an average of...

Re: Diffs again....

You would lose a bit off the line, and at all speeds actually, and drop the revs 150 RPM or so at 100k. With a 4 speed I would want a 3.45, with the 5 speed I'd leave the 3.64 in place. Your speedo will also be off by 5.5%.

Re: Suspension Trouble Shooting

If replacing with Bilstein B6, which have internal bump stops, do you think there any additional benefit to including the aux spring? Here's a link with pictures showing the internals of a Bilstein strut cartridge and the internal bump stops. https://legacygt.com/forums/showthread.php/blistein-hd-b...

In your comment above you say " aux spring" . Same thing as bump stop? I haven't heard the term aux spring before.
Yeah, I've seen it referred to as a variety of things. I've seen the aux spring description in some manuals and I think it's BMWs nomenclature.

Re: Suspension Trouble Shooting

And don't forget all tires of a given size are neither the same size nor the same shape. Some will be more of an oval cross section, some more of a rectangle. Don't forget the aux spring goes on the front too, if you're borderline that could make the difference. https://c1552172.ssl.cf0.rackcdn.com/...

Re: Suspension Trouble Shooting

I'm guessing you're rubbing in back, and guessing you have big 17s on there too, like maybe E39 size? 235/45-17? That's a big tire to try to squeeze in there without any modifications. I've got 225/50-16s on mine, 8" wheels in the back even and only rub under the most severe conditions, like literal...

I was wondering about the remaining 3 litres - thats in the torque converter - how is that flushed out/replaced -
That's the point, it can't really be flushed out except by repeated changes. First change it's about 50% new stuff. Second change it's about 75%. Third change it's up around 90%.

Re: L jet info - running rich

I did that by accident when I put L jet off an E12 onto a Bavaria. It wasn't rich, it was pig rich, black smoke rich. It ran, but not well. Didn't take too long to figure it out going over the schematic.

Re: ZDDP and Oil

ZDDP is still a big deal on Mye28 and other places. I've never thought it was that big a deal personally, although my M30s haven't seen many miles in the past decade either, although my E28 did until '09 and no visible wear on the cam. 10-40 is a bit then, but I guess with your location you don't ex...

Re: zf 3hp 22 transmission oil change.

Yep, they like fluid changes. No need for synthetic, although it shouldn't hurt. I would suggest the next engine oil change or two to change the fluid again. Remember, the system holds much more than 2 L so you really only changed a small part of it. Next time though just pull the drain plug, don't ...

Re: Strange Stall/ No Start - Overheated coil?

There's been some threads about repairing them in the past, IIRC it was bad solder joints or something. So you might find something in a search. Never had any troubles with one so I've never been inside one myself.

I swear it's more expensive than when I looked 2 weeks ago, I'm not seeing anything cheaper than what you've found.

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.
