Keeping in mind it's an M5, I have written up everything so far on M5Board as referenced a few pages ago, but will collect everything when it's done and put something together. I'm sure it's not that different on the E9x, but can't speak from experience.
The problem is, I have such a hard time blocking off time to work on the car (joys of a 200 year old house) that once it comes apart I want to go after all sort things I find. Scope creep is killing me as now I'm into replacing the VANOS high pressure pump, front and rear main seals, the clutch and slave cylinder, VANOS solenoids, and VANOS high pressure lines. Yet all of that is costing me in parts less than I would pay to have bearing done at an indy.
This level of engine work is completely foreign to me. I installed the ESS VT1 kit on my E46 M3 and swapped diffs and coils, but this is new to me. Going by the info I've found on the boards from guys who have done it before and following along with TIS, it's really not that hard. Yes, it can in fact be done on jackstands with a transmission jack to help out.
Notice on the cylinder 8 picture, there's a small circle on the upper shell and a square imprint on the lower. These I suspect are from the one attempt I made to start the engine after the injector failed open and it turned over twice before hydro-locking. There is a nice hole on the rod journal that (oil passage) that fits that circle perfectly. The square? No clue...
However, I don't for one second believe that the hydro-lock had anything to do with the wear on the other bearings. It's perfectly consistent with every other S85 bearing set we've seen.
