PCV to oil catch can= vacuum leak.

Literally replaced PCV with open vented oil catch can. Used a very snug fitting rubber cover for intake inlet cover. No leak there. The issue is not understanding the system fully, I guess. At idle, there is a vacuum applied to the open air side of the catch can.
I remember something about the 3 crankcase vents interconnecting and meeting up with another vacuumed set of hoses. I'm guessing my vacuum is there.
Should I reattach the open air side to the intake? I don't want to do that, as it will introduce some vacuum to the crankcase, when boosting.
Solutions?

Check valve. My head's killing me today, but I still would likely have missed the opportunity. Thx again.

Y-pipe hole is covered. The can is hidden well. It's a very tidy install, but I did not know that there is a vacuum applied somewhere on the engine side of PCV.

catch can --- hose to PCV from engine
The PCV has one end on Y pipe, other has hose from engine. Covered Y pipe hole, put catch inlet on the engine hose using barb.
The catch will be refitted with a one way valve on the outlet side. This will permit air exiting but not entering.
