Since the car was new it seems unlikely that it could be the piston rings. The original owner never modified the filters either. It seems the problem must be caused by something else.

George and Mike found something else. Is it possible this could happen at the factory during assembly? The picture shows a vent valve? George said that one of them was in backwards?

What do you think? Is it possible? I know the engine at one point had the valve seats replaced and it might have happened then but the dipstick blow out happened prior to that.
