Tristan, I'd run them to a can. My Lightning truck also has a problem of putting oil into the intake, blower, and intercooler and over the years it causes a decrease in performance. One solution, as you've mentioned, is an oil separator in the PVC system.

However, this is a race car and the PVC system is purely an emissions device. You are allowed to remove it. Plug the intake side of the PVC system and run the crankcase/valve cover lines over to a can. You won't have an intake leak that way and you'll be running the same system that pretty much every other IT car does.

FWIW the 260Z had a PVC system but no longer. Intake holes plugged and lines run from the crankcase/valve cover to the catch can.
