SOURCE: 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.

Ok when you're looking at your engine look at the valve cover with a black rubber hose with a funny plastic piece which fits into a rubber grommet in the valve cover. This is the pcv positive crankcase ventilation valve. Remove the pcv from hose after you've obtained a replacement throw it away insert it into the hose then the valve cover and you're good to go

Should be a little plug bunged into the top of one of the valve covers. It'll be attached to a hose that leads back to an air intake plenum.

Hi there!

The only hoses that should go from engine through the firewall, are the Heater and Air con hoses.

If the hose has been replaced, the heating settings may have been mis-set. The PCV valve is nothing to do with them - it regulates the oil sump pressure and engine emissions.

If this hits the spot - Please spare a moment to rate as Fixya! Thanks.
