oil in the engine

[StarDiamond]

Ok here is the problem. I have a 99 GST and my car has a really weird idel at times it feels like it is going to die an other times it surges really bad. Also when i take off the plug cover i always find oil up on the valve cover. Do u guys think that possible the PCV valve could cause the crankcase to pressurise and put the oil up there or is it something else internal. It looks like the oil is coming out of the oil cap.

Thanks Jason

About $1 from Mitsu for the Oil Cap gasket - You may be ready for a Valve cover & Spark Plug Hole Gasket set on your '99 - & If you had the Valve cover off it's a great time to pop in a new PCV.

Idle related? - Only if you were missing a clamp on a Vac / PCV hose or something...
