How do you replace the PCV valve on a 4 cylinder Ford Escape?
PCV valve is located in the valve cover. start engine, allow to idle. disconnect pcv valve from valve cover and feel for vaccum. If you feel vaccum good, if not trouble shoot system. Pcv valve dirty, hose clogged or cracked, etc. check the rubber grommet in valve cover for deteriation, replace if necessary. if the old pcv valve is clogged the the hose may be as well, clean w/ solvent. install new valve and reconnect.
How can you tell if your PCV valve is bad?
A bad PCV can cause the engine to be pressurized internally, thus forcing oil out of important seals. This can cause a white/blue smoke from your tailpipe when the oil is then burned. A clogged PCV will also cause the engine to loop while idling, and possibly hesitate under acceleration.
If the PCV valve is clogged will the engine rev up?
The engine will have difficulty in performing correctly!!

Where is the pcv valve located on a 1990 Ford F-150 351 5.8L 4wd?
Probably the same place that the pcv valve is located on my 1990 Lincoln town car with 302V8 and fuel injection(Rear middle of lower intake manifold.....can't see it because of upper plennum). If there is a metal screen under the pcv valve, you better remove it before it becomes clogged.......it WILL become clogged eventually!
Why is oil coming out of your motorcycle exhaust?
This could be caused by a clogged PCV valve, worn internal seals, or worn valve guides. A clogged PCV valve will pressurize the engine internally, which force oil past important seals into the exhaust stream. Likewise with worn seals, oil simply leaks out. Worn valve guides makes it possible for oil to seep down the exhaust valve into the exhaust stream.
Can a drity PCV valve cause misfire?
No, the only thing a dirty PCV valve will cause is a build-up of gas pressure inside the engine which make seals and gaskets fail.
Will a defective PCV valve cause as engine to not run?
If the vacuum hose connected to the PCV valve was disconnected, it would idle poorly if at all, otherwise, no.
