Trying to locate PCV on 98 Taurus w/3.0 and not having much luck. Any assistance appreciated.

The head/valve cover closest to the firewall is considered bank #1, on that valve cover closest to the firewall, on that valve cover at the front of the engine is your P.C.V. valve, if look at your stut tower and go straight the valve cover closest to it (on the same side as your coolant bottle) you will see it.
