The car is idling correct? If so, that means your PVC valve is working correctly. The PVC removes crank case pressure via the intake manifold/intake pipe. When you boost, the pvc valve shuts to prevent pressure from entering the crank case and the intake then forms a vacuum sucking out the crank case pressure. So by saying that, your PVC is functioning correctly.

OK i just trying to figure out some thing .about 1 month ago i sent my 880cc injectors to tom to do a bench test and when i got my injectors back with injbatteryadj vaues from tom i put those figures in and they were off i had to add 350 more to the values to keep the car runing.so just before i had the injectors done i noticed the change in the way my pcv was working (it want from blowing air out at idle to all the sudden having a little suction at idle so i though that had something to do with it.and i have done a BLT and it is all sealed up
