This is fu*k up

I did not realize he was not pressurizing the intake manifold at first... I think viciousgsx is right, that would be the only way for the air to get into the crankcase... Like the slight leakage past the rings in the engine, a little air leak is probably ok, if you can't even build pressure its probably not.

1 flaw to boost leak testing without pressurizing the intake manifold is most BOV's are driven off the intake manifold and actually use the boost pressure to help them stay closed, so they will start leaking at a lower pressure than if the whole system was under pressure.
