On a 2001 Ford F-150 with a 4.2L engine, the Positive Crankcase Ventilation (PCV) valve is located on the valve cover. Specifically, it is usually found on the driver's side, near the rear of the engine. To access it, you may need to remove any components obstructing the area, such as the air intake duct.
