Midway Through Plenum Repair
yup thats it, ... and intact... if the gasket were the source of the leak the oilstain would show ere it was leaking and coming in.... being that the whole maniold was covered as well as the plate it looks to be a spray pulled in from the pvc.... just my thoughts on it though... the gasket does look like it was shifted in a couple spots but not enough of a gap to cause that I think...
Probably an air pocket just under the stat....... typical.
I would think that if the PCV system were the primary culprit here, you would see most of the oil opposite where the fitting for the inlet line is, which isn't the case here.... nice uniform covering at the front, and MUCH heavier at the rear.
Also, just because the gasket is 'intact', does NOT mean it wasn't leaking. My valve cover gaskets are intact, but, they still leak....... (yeah, I know, I really need to change those......)

What i did, was run the engine at like 1500 RPM, to "pack" the coolant into the engine. Yeah, it has a pretty high 'pucker factor', but, so long as you don't get into the 'red' on the temp gauge, should be ok.
