PVC or Piston rings

Blow by is caused by leaky piston rings. Not much you can do about it other then running a catchcan or rebuilding the motor.

A PVC valve is generally used to equalize pressure in the crank case, not to limit how much flows through it. A symptom of a bad PVC valve could be a leaking oil cap, valve cover gasket, main seals, etc, not oil getting through it.

If it's letting a lot of oil through, it's doing its job perfectly well, and the problem is more likely to be in the piston rings. A catchcan is the cheapest "fix," and will keep the majority of that gunk from getting back into the cylinders.
