The PCV valve is usually pressed into valve cover on 4cyl.or one of the valve covers on 6 & 8 cylinder engines. A rubber hose goes from PCV valve to carburetor or throttle body. Good Luck Friend.

SOURCE: Changing PCV valve

you pcv valve should be located on the top or around the intake on top of the engine. It is covered by a little pcv valve rubber is easy to identify because it is similar to a radiator hose but a lot where near the size of a radiator hose...but when located, the pcv valve just pulls out and to check for it being bad, shake it and it should sound like something loose inside the pcv valve (thats a good pcv valve) but what they look like, they should be a silver looking color with a small little neck on it

P0171 OBD II Trouble Code This site may help locate the problem. Unfortunately these trouble codes do not necessarily pin-point a problem. They merely direct you to the general location of a problem i.e. a faulty system or circuit. So I advise you go down the list of possible causes, and check the PCV valve, and vacuum lines, etc. I hope this helps! Good Luck....

The pcv valve stands for positive crankcase ventilation. It is located on the top one of the valve covers with a rubber tube leading to it, I believe.

I have a 1989 buick lesabre 3.8 and want to change

Remove PCV valve from rocker cover. Run engine at i
dle. Place thumb over open end of PCV valve to
check for vacuum. If there is no vacuum at valve, c
heck for obstruction in manifold port, hoses or PCV
valve. Repair or replace as necessary.

Turn engine off. Remove PCV valve. Shake valve and
listen for rattle of check valve inside. If a clear
rattle is not heard, replace PCV valve.

Visually inspect valve for varnish or deposits whic
h may make PCV valve operation sticky, restricted o
cause incomplete seating of valve. Replace if neces
sary. An engine must be sealed for the PCV system t
function as designed. If leakage, sludging or dilut
ion of oil is noted AND the PCV system is functioni
properly, check engine for cause and repair as requ
ired to insure PCV system will continue to function
properly. An engine operating without any crankcase
ventilation can be damaged so it is important to
replace PCV valve and air cleaner breather at regul
ar intervals (at least every 30,000 miles). Check a
ll hoses
and clamps for failure or deterioration.
