I've been doing alot of searching on this subject and I need some clarification. To start off I have a 355 LT1 with a Procharger and in the LT1 section I see alot of people saying to leave everything alone because adding a breather will just create a vacuum leak, but when I got my procharger the instructions say to cap off the line that comes from the pass. valve cover to the throttle body and also the line coming from the pcv on the driver side intake and re-route both these lines to the intake before the throttle body, and then put a breather in place of the oil fill cap.
Now when I get on it oil comes out my breather and gets on my header making it smoke . Do I have something this setup wrong? I would like some feedback and especially some LT1 specific info.

 

Have you searched for PCV stuff? There have been several good threads about this. Turbo or SC its pretty much the same except SCs dont suffer from oil return problems w/ crankcase pressure.

 

I tried that too but i'm just wondering what the other LT1 guys are doing...

 

lt1 vs ls1 doesn't really matter, crankcase pressure is crankcase pressure and its a problem for all boosted cars.
