PCV system / Oiling Intake!!
I am having some problems with my C5Z06 oiling my Fast 92 intake. And it seems the catch can is doing nothing!! I was wondering if i could put a breather on the top 90* Elbow (Circled in Blue) where the line would normally run from the catch can to the nipple on the side of the intake (about 3 inches behind the Throttle Body). And ditch the line that runs to the intake completely and cap the nipple on the intake as well!! The line Circled in RED goes to the drivers side valve cover with a pcv valve installed in the rear of the cover. The 2nd Elbow on the back of the passenger side valve cover is capped, (to your left in the picture, just out of view from the camera).
I would also like to eventually put a breather on the oil fill cap as well.
Would this system work without damaging main seals etc. and still keep oil out of the intake??
FYI, I have no idea the model of the catch can as I purchased the car with all of this on it.

Put a small breather on the passenger valve cover, take the top inlet on the catch can and connect it to your valley cover, then route the catch cans side inlet to the fast. This is how my c5 z is setup and I get no intake oil, I think your issue is having the valve cover and valley cover routed into the same catch can. I doubt the valve cover is getting the "fresh" air it needs.

no need for breathers
Be prepared to have oil on the OUTSIDE of your engine, then.
Really, a good catch can plumbed correctly is all you need. Blowby gasses should enter the inlet side of the catch can and the intake hose (vacuum source) should be connected to the opposite side.
