There should be a sticker with a diagram showing the location. The sticker is at the front of the car where the latch for the hood is (above the rad basically). However, even with that sticker it isn't simple to find. From the passenger side of the engine you will find the alternator right at the top. Behind the alternator and about 6inches to the rear of the car is where you will find the valve. It is buried under some cables but it is there. it in a twist off compartment and it spring loaded with o rings so be carefull mine flew apart when I did mine. as stated above but with a step by step: 1. remove plastic engine cover (note some have "pcv" in raised letters directly above where the pcv is located 2. remove 3 10mm bolts carefully 3. remove spring 4. pcv will pull right out 5. reverse 1-4 to reassemble

The PCV valve for a 2001 Buick LeSabre is located in the top of one of the valve covers. It is a plug in unit and is easily changed.

The PCV valve should be on top of the valve cover at the back. The valve just plugs in, and slides out of the rubber hose.

Do you mean the PCV (Positive Crankcase Ventilation) valve? The PCV valve should be on the top of the motor, either in one of the valve covers or in the coverplate on top of the block.

Standing in front of the car locate the alternator and power steering gear. The PCV is just to the right between them. The cover should have PCV stamped on it.

Top of engine, passenger side To be more specific, PCV valve is clearly marked on the plastic/metal shield around top of motor that has the motor size inscribed on it/3800 and to the left of that are the letters "PCV". The valve is contained within a small cover and spring. I just changed mine, I have a 92 Lesabre,"its a piece of cake",bye

The PCV valve is hidden on top of the intake manifold down in a little enclosure. There are two small bolts holding the PCV cover. Often there is a fairly large vacuum line coming into the enclosure. Remove the cover and pull the PCV valve that sits down into a gasket. Simple

3800 engine. It's hard to see. It's on the passenger side under the wiring harness for the injectors. you have to pull them out of the way to get to it.

All new cars are Vacuum sensitive. The Oil cap and PCV valve are part of the vaccum system. If you have a vacuum leak this could cause the car to stall out.

open hood, top left side between valve covers. there is a "funky" plastic housing that turns counter-clockwise (less than 1 inch of travel). then pull straight up to reveal the "missing" pcv vavle. I own a 98 and that's where mine is. by SAR

No, on the 3S-FE there is no PCV valve or grommet. This is the 4cylinder model. The camry V6 of the same year on the other hand, does utilize a PCV valve in its crankcase ventilation system.
