What function have the PCV Valve in Pontiac gran prix 97?
PCV means "Positive Crankcase Ventilation." The valve allows crankcase fumes to be routed to the intake system where they can be burned in the engine. Replace the valve if it doesn't rattle when you shake it. If it doesn't rattle that means it's gunked up and isn't letting those gases through.
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.
