Oil in my throttle body?

I never said an oil soaked THROTTLE BODY was normal. What I said was oil residue in the intake manifold and plenum is normal. Any wet oily mess in the throttlebody and plastics is NOT NORMAL. You should have a coating in the intakes similiar to the pictures provided by the poster and that is normal oil residue. Just wanted to make sure that was clear.

I recommended that the poster do the leaky gaskets as well as the induction cleaning since there is a problem with EXCESSIVE deposits. The pcv should have been changed since the gaskets were replaced. This would have been documented on the tech sheets at the dealer. I would then check for a similiar problem prior to the next OCI.

If you look at the pictures of the intake there is no wet oil outside the chamber which would happen at removal since the intake is pulled off face down and flipped on its side. Of course we don't know if these surfaces were cleaned prior to the pictures taken.

The oil actually was settling back into the air induction when the mechanic put it on it's back and when he was putting a new gasket for the air induction he had to wipe away a lot of oil to get a nice clean surface. The mechanic wasn't happy the I was watching him do this, but oh we'll
 
Can you take a picture of the inside of the throttle body? Just hold open the butterfly and snap a shot down through the throttle body into the chamber.
 
I block off the intake side of the PCV system on my cars. Works great as the crankcase develops a slight vacuum that will help seal the rings. This too slows down the blow by formation.

When the engine has a vacuum in the crankcase there still is ventilation and the lighter more volatile compounds are more easily vaporized.

On my '97 SHO I have a condensation can that is between the oil seperator and the PCV valve. This is self draining with a check valve that seals up under vacuum and opens when there is no vacuum.
