12 Ounce! I just took the upper plenum off again (did it 3 weeks ago) and I once again found lots of oil. A large amount of oil has accumulated again and this after installing a "catch can". This much oil and oil vapor being drawn into the engine intake can't be good. I am starting to line up with you on a possible issue with the PCV system.

How long do you think I can drive it with the line from the PCV valve to the throttle bottle disconnected and plugged up? I know the engine needs to breathe, but I wanted to see if the bucking condition cleared up.

The lower sections of the intake manifold are covered with dark brown crud and goo, but the EGR ports are still open.

BTW: DPFE is working. I saw a voltage change with engine speed change. I got vacuum from the heater line.

Hey, would you believe I got the upper plenum off without taking off the cowling?
