I don't know how the CVV works but is it possible that the CVV is gunked up and routing oil to the intake and burning it in combustion instead of returning it to the crankcase?

Not likely. If it is clogged enough to not vent then it will pressurize the crankcase and push a gasket out, usually the valve cover gasket
If it is frozen it can freeze open and then siphon oil from the crankcase. That usually draws enough to make large clouds of smoke, it isn't metered to just a small amount
