Where is pcv valve 1998 buick lesabre


Remove the sight shield from the fuel rail. (it's the large plastic shield that dresses up the engine) As you stand in front of the car the alternator is located on rear left side. In front of it is an electrical connector to the MAP sensor. Remove it. Press the PCV valve cover down and rotate it 1/4 turn counterclockwise. It is actully on the intake manifold. Lift the cover, the upper O-ring and the spring from the housing. Remove the pcv valve and the lower O-ring from the intake manifold.

PCV location on a 2000 buick lesabre


Open hood, top left side between the 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 valve.

PVC valve


On the passenger side of the upper plenum you will find the map sensor clipped into a cap that rotates off. The pcv valve is under this cap and is spring loaded, they come apart and go back together kinda hard. Let me know if I can help you further.

Location of the pvc valve and the maf sensor Can't find the PCV valve to change it.


The PCV valve is part of the front valve cover and in order to replace it you have to replace the valve cover.

The MAF sensor is in the air filter housing. The connector is on the top of the housing.
