Wierd ? About Oil On Plugs... Ok here is the wierd issue. For some reason, under WOT when the car is at operating temperature, the car will ocassionally have a light blue smoke. His car is a 99 SS. All he has is full exhaust and a lid. All four plugs on the driver side when you pull them have clear evidence of oil on them. This is the driver side only while the passenger side plugs remain bone dry! We have performed a full compression test on ALL 8 cylinders and the results came up with 170+psi on ALL 8. I understand that rings are a possibility but seriously on ALL 2,4,6 AND 8! This is very unlikely. Good maintainence has been done to the car. We are thinking it may be a PCV issue or possibly and intake gasket issue on the side of the manifold. If I remember correctly though I didn't think oil flowed near our intakes on Ls1 cars...We seem to be able to blow through the actual PCV valve but we haven't actually blown through the hoses to see if maybe they were clogged. Here is an option we were considering to test the valves operation. Just running the entire system without the actual valve to see whether or not it was causing a problem. We believe that it is PCV related since both valve covers breath independently and that seems to be on of the only ways that ALL 4 plugs could have oil on them rather than the unlikely even that ALL 4 piston rings are failing on one side! Thanks for all help and please toss us some advice!

BTW the car has gone 12.7 @112mph in the quarter and runs great with no SES issues.
