In a 1994 Chevy Cavalier, the PCV (Positive Crankcase Ventilation) valve is located on the valve cover. It typically sits on the driver's side and is connected to a rubber hose that leads to the intake manifold. To access it, you may need to remove any engine cover or components that obstruct the view. It's a small component, often cylindrical in shape, and can be pulled out for inspection or replacement.
