Message After a full bottom end engine rebuild (which also included Woody's PCV re-route up top) I am burning lots of oil, especially on boost which I figure is from blow-by. I can see oil pooling in the intake plenums. The intercoolers are clean so it's not blown turbo seals.

Anyway, I'm planning to cap-off the PCV valve inlets and run the previous PCV hoses to a catch can with either VTA breather or perhaps a return to the cold air intakes. My question is this: given this proposed setup, would you keep the OEM restrictors in the PCV hoses as they go to the catch cans, or ditch the restrictors?
