How much does it cost to replace PCV valve on 2001 Ford Expedition?

Answer 1

PCV stands for Positive Crankcase Ventilation. All car engines have a PCV valve and it is located on top of the motor's valve cover. There is a vacuum line attached to it. It pulls out of the valve cover and if you shake it, you should hear a marble knocking inside it. If you shake it and don't hear anything, it's bad. It costs less than 5 bucks to replace. * 4.0L is located in the valve cover near the brake booster * 5.0L is located behind the intake manifold (engine rear)
