It is necessary, in short. If you remove it and plug the orifice, you'll
soon have oil squirting out of all sorts of places on the engine. If the
engine is running rough, it could be a PCV stuck in the open position,
but is more likely, based on general history and evidence, some ignition
problem. To check the valve, briefly close the connection to the valve
cover. If the problem disappears immediately, you need another PCV
valve. If not, it's something else, or something in combination with a
marginal PCV valve.
