Where is the PCV valve on a 2004 cavalier?

On a 2004 Chevrolet Cavalier, the PCV (Positive Crankcase Ventilation) valve is typically located on the valve cover. It's often found on the driver's side, near the back of the engine. You may need to remove the engine cover or other components for easier access. Always consult the vehicle's service manual for specific details related to your engine type.
