Need help asap

[sixftseven]

I've just got my car back from a full engine rebuild from a very very reputable shop that builds 100's of GN engines. My engine is fully built: 109 block, Gn1 ported fully ported heads and intake, Weisco forged pistons, billet caps, te45a turbo. It made over 600 rwhp but the problem Im having is excessive oil is coming through my valve cover breather. Its all over my headers, block, oil pan, transmission pan, cross member (dripping). It occurs while under boost and it doesnt matter if in 16,19,22 lbs. I have check my pcv and have adding a check valve and no change. It only seem to be coming from the drivers side valve cover breather. Any help would be greatly appreciated

Do you have breathers on both valve covers? What style? RJCRacing. Performance Products for Turbo Buicks has some nice ones that wont drip as they are designed taller & angled.

Catch can time 'till you get it figured out.

Pull the breather off while idling and see if you hear exhaust. May have blown a head gasket into the valley pan. I seiously hope you didn't as that would suck. Just a suggestion.
