Oil behind the TB Plates and in the Intake Manifold.. how? NOT PCV Ok first, my title is obvious so let me tell you what I have done:
1) Holley 58mm TB, PCV on the passenger VC with the line going into the top of the TB. NO OIL in the Line or the TB.
2) New PCV on Intake Manifold, Oil Catch Can in between the PCV and bottom port under the TB on the Intake Manifold. There is no oil in the Catch can to talk about but a little residue in the Line from the Intake Manifold however there is none going to the line to the PCV. Its dry.
Now the ONLY place I find oil is in the Intake Manifold and on the back of the TB and the TB Fins/Plates. I am not leaking any oil out the back of the Intake Manifold I checked... so it has to be under the Intake Manifold... This is an LT4 Intake Manifold...
Any Idea's where I should start looking now?
