Re: PCV valve

Positive Crankcase Ventilation. It releases the gases built up in the engine. it is in the valve cover on the drivers side. it just plugs into the valve cover and then a hose plugs in to it....very easy to find and replace.

Re: PCV valve

Yip, on the 1998 the PCV valve is in the driver's side valve cover.

It is a good thing to replace and cheap too.
