ok im installing my turbo kit and i was wondering if its ok to keep the pcv valve attached to my intake manifold. im pretty sure it is but i wanna double check. will it blow it out or keep it from opening? tia
 
My car is a 92 TSI, 5 speed. I have a brand new PCV, and when i put my air compressor on it and blow it with anything over 12 psi, air blows through. If I'm running 20 psi of boost, won't this create a huge boost leak? This seems like a big problem, I just want to cap the PCV off altogether.

Yes, it will. Often times new PCV valves are faulty.
