There's been some good discussion on PCV modification, but at the end of the day we just want to know what works for the high HP/boost race cars.

Have you:

Fed both sides of the valve cover into a catch can and capped off the intake?

Enlarged both holes on the valve cover for said catch can?

Retained the vacuum via the PCV valve & intake manifold?

Please enlighten.

Cheers

Also read a few people have blocked off the PCV valve side of the valve cover and fitted a -10 fitting to the other side.

Blocked off intake manifold port, ran both valve cover vents to a filter. Been that way for a year and vent hoses are still dry.

There is no reason to run PCV on our turbo cars unless you love the environment at idle.

You're not seriously suggesting removing the PCV valve in-line with the valve cover to the intake manifold on a turbo car are you? (and leaving the two connected without said PCV valve)

No, block IM+VC and have a vent on the hot side only to a catch can.

Believe it or not, I've still got the PCV on my 1.6 and I'm guessing, when running at 20#, that's adding to my smoke puffing when going into sudden vaccum - if it's puking oil mist out my DIY-FAIL catch can, it's doing the same into my intake (when lifting off throttle). I never really gave it any thought and thats why it's still there. After getting a CC that works, will do what you said Spooky.

Oil in intake = det. I proved this on my own car.

It does not take much oil to cause detonation.

I did the 323GTX PVC fix on my car, but I'm only running 8 psi. I was having oil coming out from under the timing belt cover (cam seals?), valve cover and oil pan under high boost, consistent with the crankcase getting pressurized. Not a huge amount but enough to get 4-5 good sized drips on the ground after coming in from a track session. And, I wasn't getting smoke because my IC was doing a good job of being a catch can.

I'm still getting a little oil hitting the belly pan. On my todo list is putting in a real catch can, then pulling the IC and cleaning it out (that sounds like fun).

No need to pull IC and clean it out. Good ol boost will do it in time.
