On the 1998 Ford Explorer Sport with 4.6L V8 the positive crankcase ventilation (PCV) will be located on the driver's side of the vehicle.

On a 1998 Ford Explorer, the EGR valve is located on the intake manifold. It is behind the throttle body.

To replace the PCV valve on a 2002 Ford Explorer, first, locate the valve, which is usually found on the valve cover. Disconnect the hose attached to the PCV valve and carefully twist and pull it out of the cover. Install the new PCV valve by pushing it into the valve cover until secure, then reconnect the hose. Finally, start the engine to ensure proper operation and check for any leaks.
