1990 525i (M20) 5spd w/184,000 miles.
I plan on doing a full (Bentley in hand) Service II including replacement of the timing belt/water pump and all other belts & fluids and O2 for the first time. In addition to asking for advice for a first timer I'd like to ask if anyone knows what pully bearings up front are prone to going bad. My car has a pulley noise up front that I can't locate for sure. It's not a belt slipping or a vacuum leak, but that constant whine you usually hear coming from a Ford POS. I'd really like to fix the wheezing sound while I have everything torn down up front.
Also, what is the best oil for the manual trans?
Thanks for your help!
