As engines age carbonsoot and contaminants that contribute to smog and hydrocarbon emissions.
If the click sounds or feels mushy replace the valve. The PCV positive crankcase ventilation valve is a one-way valve that recycles crankcase gases back into the engine to burn. A plugged PCV valve can result in a rough idle and poor mileage.
Worse it can cause costly oil leaks.

A PCV valve thats supposed to regulate the flow of these gases is the heart of most PCV systems some newer vehicles dont have a PCV valve. The PCV valve routes air and fuel from the crankcase back through the intake manifold to the cylinders rather than allowing them to escape into the atmosphere. There are two 4 cylinders available in the 98 Cavalier a 22L and a 24L.
