Hello all, I just paid to have the rear main seal replaced. When they had it apart and the exhaust manifold off they said that they noticed oil in the rear exhaust port on the driver's side. They said it was probably the valve guide. Question: This appears to be a minor amount and it doesn't seem to affect performance. My question is: How vital is it that it be fixed at this point. What's the worse case? Oil fouling on the spark plugs? It seem strange that only one port shows evidence of a problem
