I'd like to point out that excessive crankcase vacuum generally won't cause excessive oil consumption, although it will accelerate wear in certain areas of the engine (such as cylinder walls) because it pulls the oil back into the crankcase.

It sounds like what you're experiencing is excessive pressure, likely from blowby.

The PCV valve fix should reduce oil consumption if anything.
