So I've been reading about Z06 Catch Can

[XfireZ51]

I installed an oil/air separator last year on the ZR. One thing I have noticed was how much cleaner my exhaust tip are now. They don't have a sooty film over them, and they clean sooo much easier now. However, I have been reading about the C7Z06 and the catch can being used there. It utilizes 3 inputs/outputs.
They also utilize a check valve flowing away from the catch can to the vacuum source. Of course, the Z06 is boosted and so I don't know how that changes things relative to our NA motor.
There's a post here that discusses the install of the Z06 can.

Wondering if the check valve is something I should consider. I am assuming th chck valve shuts off flow from the can to the plenum when going WOT.
Anybody lend any clarity to all of this?
