jterp Erster Beitrag: 26. September 2003 Letzter Beitrag: 29. September 2003 I've been talking to someone about buying a 99 m3... Sometime in the cars' life the driver missed a shift and over revved the motor. Engine didn't blow, but he bent the valves. The head was removed and all the valves/valve stem seals were replaced. The head was put back on and the vanos system was put back on as well.. From what he says though, it is not lined up correctly beacause only a bmw mechanic can put it on and line it up... He seems very trustworthy and a lot of people have vouched for him so i don't doubt that he did the work correctly... my question is this: Bmw told him that it is not nnecessary to have the vanos lined up perfectly-- that the car will run the same and it will not do any damage to the motor. Does this sound right to you guys?
