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?

 

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.
