Also saw that the inside of the plenum has oily residue coating all of the inside. The large black housing that sits inbetween the valve covers. On top of the valley pan and below the airbox. What the throttle body is bolted to. Basically a bunch of oil behind the throttle body all over the inside of the plenum. Is this normal? And if not, what could be causing it?
