Question about 2003 Ford Explorer

1 Answer

I have 2003 Explorer with 4.0L V6 engine. PCV valve is really loose and won't stay inside the hole in valve cover. As a result oil is sipping through. When I checked using mirror and flashlight, the hole in the valve cover doesn't have any thread and I think it should for PCV valve retention. Did I lose some sort of insert that goes inside the hole? Please help

Yes - It should have a plastic grommet type thingy to sit in. Just push in, no threads.
Try to find one in junk yard or order from dealer.. How much could they cost?
You could try an actual grommet.. but must be oil resistant.

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.

2002 chevy tracker pcv valve location

It mostly depends on engine size...however all (PCV) Positive Crankcase Ventalation Valves are plugged inside one of the valve covers with a small clip to hold it and a breather hose is connected to it..You can go get the part to see what it looks like then you will know...also ask sales clerk and he will be glad to tell you...Some are near the valve cover.(The valve cover is normally where the oil fill cap is located ).Yours (Pending engine) should have a green ring around it if it has never been replaced..Look near the spark plug at the back of the engine and you will see it...Before you attempt to change it be sure engine has cooled down and car is in park with park brake is engaged..disconnect ground cable from battery for safety and to reset computer to clear all trouble codes if any were present.clean around area to remove any contaminants that might fall in placement hole..Remove hose,use small plyers and lightly pull on placement clip..(Don't drop the clip)...Twist valve back and forth while pulling and it should pop out..clean the hole area,use a flashlight to look inside and look for oil cake build up or trash..lightly lube around installation end of new PCV Valve...twist and push to install..install clip/hose..connect battery...Complete...Hope this helps...Brooks/Metalpoet....

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

Hose on left side of engine on top is coming lose and shows oil residue

our hose I believe is the pcv valve. Pull one end out of the valve cover and there will be a 1" ck valve. If that is where its loose, It is the grommet that needs replacing. The rubbring in the hole.

Where is the pcv valve located on a 1999 ford explorer? Is there a picture?

PCV BasicsPCV stands for Positive Crankcase Ventilation.
All car engines have a PCV valve and it is located on top of the motor's valve cover. There is a vacuum line attached to it. It pulls out of the valve cover and if you shake it, you should hear a marble knocking inside it. If you shake it and don't hear anything, it's bad. It costs less than 5 bucks to replace.

  • 4.0L is located in the valve cover near the brake booster

  • 5.0L is located behind the intake manifold (engine rear)

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.

    1998 Ford Explorer sport 4.0L 4x2 PCV Valve Location

    the pcv is located on the rear(firewall) of the drivers side valve cover.turn counterclockwise and pull to remove be careful there are 2 small tabs inside the pcv hole in the valve cover(can feel with small finger) this is to hold valve in place so it wont leak.if you have a oil leak at the pcv a quick fix is to put a small amount of silicone around the pcv o-ring and install.wait hours for silicone to set up.
