I think you both have the wrong idea of what I've got. Not saying that "if this then that" that you're saying is wrong, only that your assumptions are wrong.
EDIT: I should also mention the two nipples on the intake runners normally connected to the PCV are also capped.
This picture sucks but you can kinda see:
Basically this diagram:
My VC is not pressurized and VC breather/venting is isolated from the intake and exhaust.
So again. I'm not saying this is the best way, I accept that positive vacuum is the preferred way. This is what I decided on and I've made my decision on oily pipes vs perfect setup. There are too many examples of various configurations that run fine to get too worked up over this.
