I recently purchased a C5 with this setup and there is a film of oil all over the intake and passenger head. Does this appear hooked up correctly? Any tips? **Also is it fine that the Evap? line is open on that drivers side?
What in the jerry rig is going on here, kind of hard to see what you have going on. Pictures dont explain well.
Well this gives me hope that I can correct the problem lol I would have been let down if you said it all looked right.
It appears the rear PCV on the driver side is just pinched shut, the Evap line is left open as the intake isnt factory. On the passenger side the front and rear valvecover ports are tied together going to the top of the can, and there is one going to the intake behind TB with a check valve. Then of course that filtered vent lol
The drivers side pinched vent doesn't look good. You can replace that valve cover with the Dorman fixed orafice valve cover 264-949(Amazon) and plumb that back into the intake. That would probably help.
This is what I would do.
On an NA setup like yours, I’d run a closed system instead of a "vented catch can".
I would run it like this driver side valve cover → catch can inlet
Catch can outlet → intake manifold (vacuum port behind throttle body)
Passenger side valve cover → intake tube before the throttle body
Right now you’ve got both covers tied together, one side pinched, and a vented can, so there’s no proper vacuum pulling vapors out. Probably why you have oil everywhere. Also id just cap off the evap line and anything else not being used, I warn you idk how your car is tuned so it may need adjustments once fixed.
