Thanks for the info. No oil leak to speak of. I will look into the PCV system. My motor is stock, but I do have a catch can. I noticed that mine had a little filter on it and the filter was cloged with oil. To be honest, my engine seems to have a lot of vacuum everywhere, including the catch-can. Is this a bad thing? What does it mean?
Is it possible that when my catch can got cloged, it created an intake leak from the intake manifold to the valve cover somehow?
