Replace the PVC valve, it's probably clogged.

SOURCE: 3.8engine using oil 1 qt week

Your pcv system is designed to handle normal amounts of internal crankcase pressures. If your rings are a bit worn, you will have higher internal pressure that can and will drive oil out through pcv or sometimes even the dipstick tube. This wear can be detected by doing a cylinder leakdown test (air is blown into each cylinder and the amount of pressure drop is measured) . If leakdown is greater than normal, you will then need to decide if it is worth it to do a ring replacement (major job), drive it as is and perhaps use a heavier oil, or sell it. If your engine uses any other venting for the crankcase, make sure that is not plugged up (I don't remember seeing anything lkie that on your engine though)

SOURCE: on a 2004 Impala what is that pipe/hose called

I beleive it's simply called the PCV hose. If you go to the auto parts store, the hose may come pre-formed or they will be able to supply you with the correct diameter hose. I would take the old hose with you for a match up.

97 expedition 5.4 doesnt idle very good

Surging idle is usually caused by vacuum leaks. Ford 5.4L engines are notorious for the PCV hose elbow leaking back behind the throttle body.

The PCV tube goes from the right (passenger) side valve cover and loops around behind the valve body. Inspect this hose on BOTH ends.

I have a 97 mazda mpv and need to find the pvc valve on the engine?

PVC Valves do not need to be replaced
Never have

99% of them, have been on the valve cover
for at least 40 years

Unless you have a pcv vacuum hose leak
they do nothing, as far a your engine goes

They are there to regulate crankcase fume

Need to start studying & stop listening
to all the hype,including repair shops that
sell these things for no reason.

Oil leak at the rear of the valve cover on the right side does not appear to be the valve cover gasket. another issue is the check engine light and the code is 743 and the o/d off light is blinking.

This isn't a solution, but I have a similar oil leak. I can see clearly with the help of a telescopic mirror that the leak is emanating from the port where the PCV valve hose goes into the cylinder head.

Where is the Pvc valve on a 1997 nissan xe pickup?

1997 Nissan pickup its just above the oil filter, lower right of engine, access through right front wheelwell after removing wheel, it's a screw to be removed. -------------------- The pcv valve on the 2.4 l engine is located behind the alternator and the engine oil filter. The best way to change it is to go thru the wheel well. Take off the passenger front wheel, lift or remove the rubber splash curtain, remove the oil filter, disconnect the rubber vacuum hose, then use a 19 mm wrench to remove the pcv valve. ----------

Thanks. keep updated for any more can rate this solution and show your appreciation.

Where can i find pcv valve of 2.5 engine mazda mpv,where is it mounted in the engine

PCV Valves are located on top of the valve cover and allow gas to escape from the blow by of piston gases.
Look for a black plasltic piece that is inserted into the top of the valve cover near the front of the engine with a rubber hose connected to it.

Where is the pcv valve located on a 2003 ford ranger

  • The PCV valve can be located in several places. The most common location is in a rubber grommet in the valve cover. It can be installed in the middle of the hose connections, as well as installed directly in the intake manifold.
  • Once the PCV valve is located, make sure all the PCV system hoses are properly connected and that they have no breaks or cracks.
  • Remove the air cleaner and inspect the air and crankcase filters. Crankcase blowby can clog these with oil. Clean or replace such filters.
  • Oil in the air cleaner assembly indicates that the PCV valve or hoses are plugged.
  • Make sure you check these and replace the valve and clean the hoses and air cleaner assembly.
  • When the PCV valve and hose are in satisfactory condition and there is oil in the air cleaner assembly, perform a cylinder compression test to check for worn cylinders and piston rings.

    Nissan pickup 1994

    the pcv valve is behind the alternator between the alternator and oil filter. when you remove the oil filter you can see the pcv in the intake manifold. best way to get to it is through the pass side fender under the rubber mud flap thats between the wheel and engine.
