How to Replace a PCV Valve in a 2000 Taurus
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.

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.
2Grasp 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.
3Discard 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.
4Push 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.

How to Locate the PCV Valve on a 2000 Lumina
The standard layout for automotive PCV (positive crankcase ventilation) valves was developed when rear-wheel-drive vehicles were the only kind on the road. The PCV concept became common in all internal combustion engines, including those in front-wheel-drive cars. The 2000 Chevrolet Lumina is a front-wheel drive vehicle with a sideways ("transverse mounted") engine. The emissions control system in the Lumina engine is basically the same as in other cars, but the PCV valve is placed in a different location than on other vehicles. Locating the PCV valve on a 2000 Chevrolet Lumina takes just a few minutes and no tools.

Remove the engine cover, if one is present. Disconnect the oil filler tube by grasping it firmly and rotating it counterclockwise. The tube will lift out at that point, and the cover will pull right off.
2Disconnect the vacuum tubing from the PCV valve on the 3.1-liter engine. The PCV valve is positioned on the passengers side of the engine along the back firewall. You will notice the tubing connecting to the top rear corner of the valve cover. That is the vacuum tubing. The PCV valve pops out when pulled. Inspect the unit and replace as necessary.
3Disconnect the MAP sensor on the 3.8-liter engine to access the PCV valve. The sensor is positioned to the left of the spark plug wires just in front of the alternator as you look at the engine. The MAP sensor sits on top of the PCV cover. Unclip the sensor. Twist the cover about 1/8-turn and pull it free. The PCV valve sits in the housing and just pulls out. Remove and inspect the unit. Replace as necessary. Installation is the reverse of removal.
