Does a 1998 Chevy Cavalier 2.2 have a PCV valve?
Yes, all cavaliers from any year have Positive Crankcase Ventilation (PCV) valves.
Yes. The PCV valve is attached to the intake by a hose and is located in the valve cover and held by a plastic retainer. Use a pair of pliers to loosen the PCV valve retainer. Unthread the retainer from the valve cover to expose the PCV valve. Pull the PCV valve from the valve cover grommet and remove the valve from the hose.
