The PCV valve should be in the right end of the front valve cover in a rubber grommet
The fuel filter is located in the fuel line underneath the car on the driver's side, infront of the rear wheel.

Location of pcv valve 95 nissan KA 24 engine hardbody


Follow the breather hose(s) to where they meet the engine and that is where the pcv valve is usually to be found if your engine has one; valve cover, crankcase or inlet manifold are the likely locations.

Not all engines use a pcv valve. Many engines just have a tiny hole into the inlet manifold which typically soon blocks and needs cleaning.

Ford was one of the manufacturers who in the early days of a pcv system being required, used an oil filler cap to attach the breather system to and the tiny hole was inside the cap along with the flame trap and oil mist filter.
That like many of the plastic pcv valves was intended to be a throw-away item.

I hope I have helped you a little.

2003 chevy impala makes clicking noise/smoking thru exhaust


the clicking noise could be eiter a valve or piston. the smoke out of the exhaust means different things depending on the color and how much smoke. Check your air filter and make sure oil is not backing up into it. Also, it may be a good ideal to go ahead and change the oil even though you arent at 3000 miles, unless you just changed it. Change the PCV valve also, if itis clogged it will give you problems. Has the check engine light come on?

2003 ford taurus idle problems had trouble codes


A code P0174 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure

I want to replace the fuel and PCV valves but I am unsure where they are in the engine compartment. Is there anywhere I can find a layout of the engine compartment that is accurate?


The PCV valve is a small plastic right-angle pipe located in the rear (firewall side) valve cover, on the passenger side end of the cover.
It can be removed by hand.

The fuel filter is located underneath the air filter box, it is a black metal cylinder, mounted vertically, about 6 inches tall and 3 inches wide with pipes mounted to the top and bottom. The lower is a 14mm flare nut, the top is a 17mm banjo bolt.

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.

    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.

    PCV valve location


    if i know what you are asking, look at where you put your oil in. on the valve cover to the top right should be a plug with a tubeing runs to your air clear tube where the air mass sensor and carb is located. i think that is what you are looking for.

    PCV Location


    Thank you for your follow up. I fixed my problem by finding a hard working mechanic, not a dealership. When I got 3 estimates on replacing the PCV and the Fuel Filter on my 2003 Nissan, there was a $59 difference between the high and low bid. Obviously took the low. Thanks again! Postit2
