I run an exhaust scavenging setup for under boost conditions and the PCV for idle periods. I have two -10 male fittings welded to my VC and the factory PCV system.

Yeah I really want to keep the crankcase under VAC as much as possible. That metal plug is pressed in there not theaded, it not coming out without a lot of work.
Maybe I can just run 2 lines and conjoin them with another T fitting it to the catch can with one line.
I am also looking for 3 port catch cans but there are not many to be found. Was think of just running 2 lines off the valve cover T to catch can, then back to the turbo intake. Just to retain vac.
Im not sure I understand your setup too well.
