I’d think you’d want to use that for crankcase venting rather than the intake so you’re never pushing positive pressure into the crankcase.

It's not a vacuum source until the air filter becomes the most restrictive element in the system. Compared the factory PCV system, it would be the fresh fitered air source to feed the crankcase.

Fair enough, I guess I should say it's not a positive pressure source. Idk if I want to vent my valve cover back into the turbo.

Putting my PCV into the front of my D1 blower made for an oily mess in my intercooler. You'd be smart to not send your PCV to the turbo inlet, IMO.
