Where is the PCV located on a 2001 Lincoln Town Car?

The PCV valve on a 2001 Lincoln Town Car (assuming it has the 4.6L engine, which is most common) is located on the valve cover. It's a small, usually black, plastic valve. It's usually near the back of the valve cover, towards the passenger side (right side) of the engine.

However, the exact location might vary slightly depending on the specific engine configuration. It's best to consult a repair manual specific to your vehicle's year and engine (4.6L or other) for a precise diagram.
