In that lovely pic you added both lines from A & B go to the catch can.
That means where your black hose goes from is blocked (the turbo inlet pipe) and the one way valve is removed and the hole in the plenum is blocked and both the cam cover vents go to the catch can, no fumes are sucked out by the engine.
Does you air/oil separator have a open top (filter) or is it sealed??
If it is sealed you have half of the job done, you also need to take the other cam cover vent (by the plenum) and put that into the separator too.
