So forgive me if this is a dumb question but wouldn't closing off the PCV lead to essentially the same thing happening via some other channel?

You have a vent on the other valve cover that allows air to be sucked in. If you chose to dispense with your PCV entirely, you would still vent the engine. Most of us, but not all of us by any means, choose to run a PCV on the street as it keeps your engine a little cleaner on the inside. One old fashioned trick to monitoring crankcase pressure is to see if your dipstick is getting pushed up out of the tube (which is another vent, kinda). Plugging your PCV tube should tip you off pretty quickly as to whether that's the problem.
