2000 Ford Taurus Replace PCV Valve
The PCV, or positive crankcase ventilation valve, on the 3.0-liter engine in your Ford Taurus requires attention from time to time. As the valve gets old, it will allow oil and vapors from inside the engine to leak out. The PCV system removes excess pressure and unburned gases from inside the engine, recirculating the gases through the engine to be burned and expelled out of the exhaust. This decreases the emissions from the tailpipe and allows your car to run cleaner.

 Replace PCV Valve
- Open the hood of your Taurus and locate the PCV valve on the top of the valve cover. The PCV valve looks like an L-shaped fitting plugged into the top of the valve cover and has a large hose attached to it.
- Grasp the PCV valve and pull it straight out of the valve cover grommet. Grasp the hose on the end of the valve and separate it from the valve. Lay the hose aside for now.
- Discard the old PCV valve, then insert the end of the new valve into the end of the rubber vacuum hose that you removed from the old valve. You may need to twist it a little to get it to slide in place.
- Push the new PCV valve into the grommet on the top of the valve cover. Make sure it seats completely in the grommet so oil does not blow past it. Close the hood.
