The passenger side valve cover on my 98 Expedition 5.4 has the PCV valve. The driver's side valve cover has a soft elbow with hard tube that goes into the throttle body plenum.
Here is a picture.
What is the function of this?
When I removed my intake plenum, there was oil in it. I replaced my passenger side PCV valve, since that was presented as a potential problem, but now that I see this. Is this another PCV valve? Is this another potential place where oil could enter the intake system?
When I removed the hose, it had oil on the outside of this piece.
