Ok, ideally no boost. However, if the bypass valve is partially opened letting compressed air from the blower and uncompressed air from the throttle into the engine, doesn't that also allow boosted pressure back to the PCV? If so, then a check valve in line with the PCV would get us the ideal no boost config at the PCV.
Here's another question: if there is blow by pressurizing the crankcase, and it blows out through the PCV into the blower, isn't that unmetered air getting back into the intake after the MAF? If so, a vent to air path for the PCV would solve the problem (like others have reported), right? Would routing the PCV to the same CCV port on the air box also work?
