I recently purchased a 96 Z28 Camaro with the LT1 Engine as a
fix-r-uper. The car has high milage and was running rough when I
bought it. Upon inspection, it became apparent that something ugly was
happening with the air intake system, and having taken off the throttle
body, I found out what it was.... Oil!
It appears that oil has been coming through the vent hose (the one
coming from the passenger side valve cover) into the top part of the
throttle body and then down into the intake manifold.
I am hoping that someone can explain this to me. The oil doesn't
appear to be coming from the PCV valve but, instead, from the hose out
of the passenger side valve cover. What could cause this?
I noticed this afternoon that the oil level on the vehicle is about an
inch higher than the "maximum" indicated level on the dip-stick. Could
this account for the trouble? Is this engine rebuilt time or are there
any other alternative explainations? Any thoughts/advice/suggestions
would be greatly appreciated.
