see FSM?
open hood
touch valve cover. with finger,
now see 2 hoses. on VC. about 1inch OD.
one is PCV fresh air.
and one is PCV valve hose. that hose. the one with the PCV check valve device on the end.

first thing check make sure oil pan drain plug tight. check make sure oil filter tight. try tighten oil filter by hand see if turn tighten oil filter clockwise direcction if all is good. how many miles on vechicle.could have oil leaks park vechicle in spot that clean.move vechicle see if you see oil spots on ground if yes.your front timing cover seal leaking oil or rear main oil seal ;eaking.or valve cover gaskets leaking.if find no oil leaks more likely engine burning oil.replace pcv valve.check air filter if you see oil in air filter housing either have bad pcv valve or pcv not getting vacuum make sure pcv valve getting vacuum when engine running vacuum should be felt at pcv if not pcv valve bad or pcv hose disconnected broken or plugged.if pcv valve okay engine has worn piston rings.worn valve seals or guides or oil return holes stopped up thats all possible reasons for engine burning oil.if spark plugs oil fouled engine burning oil.

shake the pcv valve up and down if the valve makes a noise its good if it doesnt repace it

sound like idle speed control problems, if you see check engine flashing code scan for faulty idle air control valve or faulty egr valve which sticking open, if all is good check see if you vacuum leak at pcv valve or pcv valve hose check see if pcv getting vacuum and see if pcv valve rattle if shaken if not pcv valve faulty.

The PCV valve (3) is mounted into the top/right side of the intake manifold (2).


1.The PCV valve (1) is sealed to the intake manifold with two O-rings (2).
2.Remove PCV valve by rotating counter-clockwise 90 degrees until locating tabs (3) have been freed. After tabs have cleared, pull valve straight up from intake manifold.3.After valve is removed, check condition of two valve O-rings (2). __________________

Not sure on your engine so heres both types. :-) Hope it helps. Cobra
Positive Crankcase Ventilation (PCV) Valve — 3.0L (2V) Removal and Installation

1. Disconnect the positive crankcase ventilation (PCV) valve tube quick-connect from the PCV valve.

CAUTION: A new PCV valve must be installed if removed from the cam cover. Damage will occur to the locking mechanism on the PCV valve.
Remove the PCV valve.

• Disconnect the PCV valve electrical connector.

• Rotate to release and remove the PCV valve.

Positive Crankcase Ventilation (PCV) Valve — 3.0L (4V) Removal and Installation

1. Disconnect the positive crankcase ventilation (PCV) valve tube from the PCV valve

CAUTION: A new PCV valve must be installed if removed from the cam cover. Damage will occur to the locking mechanism on the PCV valve.
Rotate to release and remove the PCV valve.

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
r
cause incomplete seating of valve. Replace if neces
sary. An engine must be sealed for the PCV system t
o
function as designed. If leakage, sludging or dilut
ion of oil is noted AND the PCV system is functioni
ng
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.

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 hose...it is easy to identify because it is similar to a radiator hose but a lot smaller...no 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

 rough-idling engine can signal a number of positive crankcase ventilation (PCV) valve problems, such as a clogged valve or a plugged hose. But before beginning the functional checks, double check the PCV valve part number to make certain the correct valve is installed. If the correct valve is being used, continue by disconnecting the PCV valve from the valve cover, intake manifold, or hose. Start the engine and let it run at idle. If the PCV valve is not clogged, a hissing is heard as air passes through the valve. Place a finger over the end of the valve to check for vacuum.



With the engine at idle, vacuum should be felt at the PCV valve.
