So i looked up from the maf location and saw oil, in the groves, theres enough to fill up two or three groves down towards the maf and a coating from where the blow bye tube comes in, to the throttle body, is this normal or do i have a problem here?

 

Ours was oily there too on the 1998 engine with 524K miles but bone dry on the 1998 engine with 119K miles so I guess it could be an wear related issue. I do not know the kind of air flow comes out of the right valve cover back into the intake manifold.

 

Yea this motor only has 90k on it, and always been well maintained so, i dont know maybe a pvc issue, but i dont know
