The 2 hoses I have going from the valve covers to the intake manifold have oil in them, a lot of oil in them. Dealer replaced both pcv valves over a month ago in their quest to find my smoking problem. Does this happen with scored cylinders? I put a scope in cylinders 1 and 3 and the scratches I would call very very light, like a ball point pen drew on them. And I found out that a "new engine" is only the bottom half. That's gross for $20000.
