Two weeks ago I was going to take my car out for a drive, but at start-up it smoked the whole neigborhood. At first I thought it was the turbo, but when I pulled it off oil was dripping out of the rear exhaust port. So out came the engine, tore it down. Could not find anything wrong. The oil control rings and o-rings were new 10k miles ago. The rotors were cut to use 3mm apex seals. So how can so much oil get into the combustion chamber?

were the oil control ring springs put in the right way? ive taken a bunch of rebuilt engines apprt with those nto being in the right way. that will cause premature smoking.

That is what I thought before I took the engine apart. But the springs were in the right way when I took the rings out. The o-rings still looked new.

was that rotor oily? the oil control rings are pretty much always to blame for the oil in the rotor. were the o-rings installed well? not jammed?

Well found out what was wrong. The apel seal grove is cracked. The rotor is junk now, anyone have one you can sell me? It is for a S5 turbo.
