you can eliminate the stock PCV all together, but its best to have a check valve to replace it. Or something that can open an release the pressure when needed. Its shouldnt be "open all hte time". this is why its called a POSITIVE CRANKCASE VENTILATION. ITs only designed to work when there is a positive pressure, not vacuum

there are millions of ways to run a PCV system, im just going from personal experience. Dave an i tried about 10 different theories on the dyno, an some ways produced more smoke then others, some ways lost power, some ways gained power.

the best way to do it IMHO is to run it the way i said earlier in the thread. Run a baffled catch can with 2 vents off the vavle cover. Run a hose from the PCV to the valve cover with a breather filter in between. that way its not fighting pressure it vents in between. then you run a hose fro mthe top of the catch can down to the slash cut in the exhaust.

BTW:90% of the catch can setups i see, are wrong, or improperly setup.
