What is the symptoms of a bad PCV valve?
Generally speaking the symptom of a bad PCV valve is a buildup of pressure inside the crankcase. If it is bad enough it can cause the engine oil to come out through the dip stick tube. If you pull the dipstick out and hear a release of pressure that is probably an indication of a bad PCV valve. The common way to check the PCV valve is to take it out and shake it. If it has a rattle then it is supposed to be good, no rattle it is assumed to be plugged up and no longer working. I am not certain if that is still a valid check.
How can you tell if your PCV valve is bad?
A bad PCV can cause the engine to be pressurized internally, thus forcing oil out of important seals. This can cause a white/blue smoke from your tailpipe when the oil is then burned. A clogged PCV will also cause the engine to loop while idling, and possibly hesitate under acceleration.
