Valve stem seals?

"I noticed one thing, when i replaced my exhaust manifold gasket and turbo gaskets i saw oil sitting in those little journals inbetween the exhaust ports on the head. Now do my exhaust valve guides poke throught there at all?"

Nope. Those are just hollow areas cast into the head. I had the SAME exact thing happen to me when replacing my exhaust manifold gasket 2 years ago, those holes were filled with oil and I was like WTF? In my case, it was coming from my leaking Cam Position Sensor O-ring. My engine did the same thing, little smoke coming from the exhaust manifold while running and at full operating temp. I'm willing to bet money that your CPS O-ring is leaking. It's only a $2 part from the dealer and takes 10 minutes to change.

That much oil in your engine will not ruin your rings or your valve guides. What it WILL ruin is your rear main seal, front main seal, oil pump driveshaft seal and oil pan seal.
