Can anyone tell me exactly what is needed for the 7M GTE PCV system to work correctly when after market turbo and Intercooler pipes are being used? The "3000" pipe no longer has a port for some line and just want to make sure I have this system hooked up correctly. I am also using a catch can, which seems to vent any collected oil straight to the ground. Should there be some check valve on this to prevent a vacuum leak? A diagram of what must be used would be great.
