I had a problem with oil consumption ,approx. 1 qt per 1000 miles, sometimes more. I changed the pcv valve and it would go away until the valve stuck again. So the only real benefit for me was to stop the oil consumption problem. The problem is due to the lack of or poor design of the baffles in the valve cover.The baffles keep the intake from sucking in oil when the pcv valve is open. I will try to post a pic soon.

mbeach, I have not checked it but I wll and let you know. shawn
