I recently purchased a 05 S60 T5 Awd. Really nice car, but 100 miles past warranty It threw the timing belt and blew the top end of my motor, bent 16 valves and the whole nine yards. I forked over the wad of money to get it rebuilt and after the rebuild she runs great, but it has a massive oil leak from the exhaust cam shft on the timing belt side. The pcv system was replaced and it has negative pressure like it should but the seal is still getting pushed out. I replaced the cam shafts again and all of the seals? It does not have any crankcase pressure so the seal should sit right in fine and not pour oil out? Any body have any ideas? I'm stumped on this one.
