Well, i was going to replace my valve stem seals today to hopefully cure my smoking at idle/takeoff issue and found something interesting. Upon removing my intake manifold, i found that it had oil laying in the bottom of it. I know a little bit is normal, but this seemed a little excessive. Looking at the cylinder head intake ports, #4&8 both have oil around the ports, just sitting from where the head/intake overlap and create a small flat. the hole drilled in the head to align the intake gasket was also full of oil on #8.
Upon inspecting my PCV system, I found that the opening in the pass side valve cover for the pcv valve is directly above a cam lobe and a hole from the lifter to spray oil. It's basically a staight shot from the lobe/lifter to the valve.
It has to be sucking up oil. My question, do the 4.6's have a PCV valve screen?? If so, mine does not.
Anybody ever looked down below their PCV??
