my procharged ls1 last night blew a valve cover gasket, replaced it, test drove it and then it blew the PCV valve, replaced that and it continued to blow the PCV hose off the valve, zip-tied the valve to the hose and then it blew the new gasket, its blown twice now around #5 and #7 cylinders.......whats causing this? oil pressure is around 20-40 depending on RPM, and it wants to die when at idle, this is over my head. Any thoughts?

 

Sounds like you have boost going through the PCV system. I think a lot of people with a blower ditch the PCV system and just run a breather.

If you keep the PCV with boost I think you need one way check valves so vacuum can pull air but boost is blocked.

 

Blown ringlands.

 

What he said. Excessive crankcase pressure seems to be causing your symptoms, the root cause is likely piston failure.
