how does it drains back to PCV? the car when driving in vacuum, will PULL air through PCV , sourcing it through the CCV side which take atmosphere pressure air from intake side pre throttle pre forced induction. Air will end up into intake manifold post throttle, possibly cleaned by the AOS

Then when in Boost, ideally the PCV closes and any excess in the crankcase should be getting into CCV side so into intake side pre throttle pre forced induction

Is this AOS relying on a weak oem PCV that leaks under boost and so hoping the vapours will end back back into crankcase and stay there?

Also, are the 2 collecting chambers inside the AOS somehow connected to each other so that all the oil collected by both PCV side when in vacuum, and ccv side when in boost, is going to router back together into crankcase through the PCV as said here in this thread?
if yes i see many criticality in this

something isn t right to me
