I am trying to determine the operation of the PCV in these cars.
Can you turn on the car, and on idle remove the oil cap and let me know if the air is being sucked in or blown out of the hole ?

I was told that the baseline (at least from non turbo cars) is vaccume, and that shows correct action.
But I have seen new cars with 0 miles with a blow-out as well and that was normal..

Response from T3 or T4 owners would ve appreciated. Preferably T3
Thanks !
