If you only have 7K on the engine that must mean you had a rebuild recently, and if it's not the PCV system, Isn't there something about aligning the rings on the piston so that the gaps are offset? Haven't been into an engine that far, but I thought I read that somewhere in a magazine article?? Maybe someone with experience can comment further. Have you done a compression check?
