Short term it would let the blow-by out and you could see if the system was allowing oil into the engine. Just know that the engine is calibrated for the amount of air that flows through the PCV valve, and that that "controlled air leak" won't be present. And the inside of the engine would eventually coke up from the vapors that don't get drawn off. Another feature of the PCV system is that any moisture that is a by product of combustion when the engine is warming up will also not be drawn out of the crankcase. Maybe a good short-term solution would be to run a longer hose on the PCV that goes up and over the air cleaner snorkel. The engine (I think) shouldn't be able to pull raw oil that high. Some people also use a catch-can between the PCV valve and the carburetor, to collect the oil.
