If you check out the operation of the B18 pcv hose oil cap setup I was referring to. The direction of the gases at idle are to suck the fresh air into the engine from the pcv oil fill cap. However, at higher rpms above idle the fumes reverse direction and are pumped out through the cap into the air filter to be sucked into the engine.

The direction reversal of the gases is also used by Volvo with the stock B230F pcv setup.
