Ok the PCV valve opens (not sure when) and vent's to the intake manifold, right? And the breather hose vents to the intake hose after the MAF. What discerns what goes through the PCV valve and what goes through the breather hose when the PCV valve is open? I'm buring a lot of oil and have siginifacnt turbo lag (due to I think some boost leaks). I know a bad PCV valve will cause extra oil to be blown out the oil cap/dipstick and breather hose, but is that also considered a boost leak?
I talked to a couple of techs here and they said that (at least on most German cars) the breather hose is sourced from a specific location via channels in the VC.
