I wouldn’t try to save corroded pistons. BMW shows rebuild kits including the pistons as available but check with your dealer to be sure. Or you could save yourself lots of time and contact Ireland Engineering and ask if they still offer rebuild services. I believe the issue with splitting the ...

I don’t think you can go wrong with a small amount of Curil-t, it’s known to work well.

The regrinding was $265 plus shipping which was about $80 but I’m on the east coast. The machine shop cost to vacuum/pressure test and deck the head plus a valve job is looking like $2k. Plus another $1k in parts like new rockers, eccentrics, seals, head bolts, etc. My how have things changed since ...

Dry and follow torque specs. Never had a leak there, but always a small leak around the rubber o ring housing gasket.

I replaced the Redline 75/90 synthetic with LiquiMoly 85/90 hypoid gear oil, added Redline limited slip friction modifier which seems to have resolved the chatter in tight turns without reducing the limited slip effect. I still have a bit of on-throttle whine but it's now at much higher speeds. I'll ...

The fan blades are interchangeable with e23/24/28’s and are still available new from BMW although I believe the blades are now black. The clutch is unique to early and late water pump versions and the blades fit either version.

Thank you @ John in the Glade. So I referenced what I should have in the first place- the factory repair manual. It says to use a name brand SAE 90 hypoid gear oil and nothing about additives for limited slip. My next step will be to try that without an additive, then with an additive if it still ...

Oh wait, that's The Vintage. I did have my car at the PVGP in 2024 but was invited to the BringaTrailer display so was not in the BMWCCA car corral.

Yes, that was my car.

It really comes down to do you want that badass look with +2 staggered wheel set up or do you want the ride and handling from how the car was engineered? I used the CoupeKing staggered set up with the sizes you describe for a few years and the found it was harsh, noisy and the front tires rubbed the ...

Following Mike Miller's (RIP) lifetime maintenance schedule I'm using Redline 75W-90 synthetic gear oil in my sideloader limited slip diff. I've noticed a bit of binding in sharp turns and would like to hear if anyone uses a different gear oil that could prevent this. I believe it's an older ...

Mike- Bill Arnold had a shop do mine but that was 10 years ago. Good point on the copper/brass, I imagine it’s a bit pricey these days.

As long as the tanks are solid, I’d have it re-cored to prevent future pinhole leaks.

Does the driveshaft look aligned and are the guibo and center support coupling in good condition? Could something be causing the driveshaft to bind in reverse under load? Any transmission or differential noises?

You said the new collar is silver but your picture shows both both collars. Does the yellow zinc plated collar not fit? I know that Koni struts used a different collar but the diameter of the threaded area is the same.
