On my 2000 Ford Explorer Sport 5-speed manual transmission 4.0L V6 OHV, the PVC valve is located as follows: Standing in the front of the vehicle looking at the right side of the engine on the top of the valve cover.

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 top of the front-left engine valve cover will be a grommet and hose assembly. In between the grommet and hose, and attached to the valve cover is the PCV valve.
That is a PCV valve, and it should be on the intake manifold. there would be either a rubber hose or a metal pipe leading from it to the air cleaner.
