    Yes, I understand what a PCV valve is...we are just not sure if there is one on my car and if there is one, where is it located. Also, why would the oil be pooling in the intake and how would it be getting there? Thanks for your help so far :)

WILL CHANGING THE PCV VALVE HELP SOME WITH MY OIL PRESSURE


PCV valve isn't likely to change your oil pressure at all. All it does is vent the crankcase to your intake.

I don't know your engine, but some have both a "sending switch" and a "sensor" for oil. One for the light, one for that gauge.

You could also have a bad wire from sensing switch to gauge.

DRIVES FINE FOR A BIT THEN STARTS ACTING LIKE ITS SPUTTERING ALSO HAVE A LOT OF BLOW BY IN MY AIR FILTER. WHAT WOULD CAUSE THAT


The PCV Valve is only a check valve that keeps
crankcase oil from entering the intake manifold

They can be cleaned every few years,they never have
needed replacement

Just another scam like a tune-up that doesn't exist

The cars computer has been tuning cars since 1981 with
Gm & Ford & Chrysler & all others since 1983,only spark
plugs exist from those days

People fail to educate themselves

You provided no vehicle,so google that question
about if you have a pcv
Some are part of the valve cover & as you say don't
come out

Where is the pvc valve on a 2.7 V6 Kia Optima


Pretty much all PCV Valves are on a valve cover

They regulate the amount of air evacuated from the crankcase,
& have to block off vacuum at times & prevent oil from getting into
intake,thus on a valve cover near oil

They NEVER NEED TO BE REPLACED
never have in 50 years
They can be sprayed clean, if you like,with brakleen etc

AGAIN -- a PCV unless it's vacuum hose leaks HAS NOTHING
WHAT SO EVER TO DO WITH HOW YOUR VEHILCE RUNS

2005 chevy trailblazer, rough start, stalls, gas smell, warms up idles fast, once it warms up ok. Acts like it is going to die. Sputters. Changed air filter. Changed sparked plugs, changed oil. Did...


With temperature related problems, check your intake manifold bolts for tightness. Our intakes are plastic and have a tendency to become loose, causing vacuum leaks. When it warms up, the plastic intake will expand sealing any leaks. But when it's cold, will contract, causing leaks. Easiest to check are cylinder #5 & 6 near the fire wall.

Also, clean your throttle body, a dirty throttle body will cause idle problems, especially in TB's because we don't have a true PCV valve, so gets dirty which causes sticking of the butterfly.

Where do I find the pcv valve and can I change it myself? If this is clogged or stuck does it cause oil to be all over under the hood and does it make the car use more oil?


Below is a diagram of your PCV valve. It's not a difficult repair to perform yourself as it's easily accessible. A clogged PCV wouldn't normally send oil throughout the hood. This is more likely a valve cover gasket. Look for pools of oil surrounding the valve cover. If you find seepage there, you've located the source of your oil consumption.
