The pcv valve appears non-removable do you just pull it out with pliers. it looks like its permanently mounted.it is metal.

Step 1: Identify PCV and remove connectors for space:
If you look at the back of the engine, there is a 5/8" tube running into the intake manifold. In picture #1, you'll see that this tube has a green sticker on it (red box #3). You can't see the PCV valve from this angle, but if you follow that tube down, you'll see a gray plastic piece. That is the PCV valve.



For step 1, we remove the 2 hoses and an electrical connectors (red boxes 1, 2, and 3). That will give us more clearance.

Step 2: Remove the tubes to get to the PCV valves.
Right, now you need to remove the 5/8" tube completely (the one with the green sticker). Picture #2 you can see that there are some hose-grips on that tubes, so using small pliers will help here.

After that, there is another adapter connected to that piece. Please see picture #3 and #4 for reference. That adapter must be remove because it spins freely. To remove, use your hand (no tools needed). Press the green adapter to release the grip and pull up.

Step 3: Remove PCV valve
You can see the full assembly in picture #3 and #4. Next is to remove the PCV valve. There is a shallow thread on that PCV valve, so you'll need to turn it to remove it. Use something to help you, like a clamp or pliers and rotate the PCV valve 1/4 turn counter-clockwise. This will be kind of difficult, but just keep working on it and it will loosen and pop out. A long reach nose-pliers can come in handy. In picture #5, you can see how tight it is down there.

Step 4: Replace and reconnect.
Replace the old PCV valve with the new one. Reconnect all the other hoses and connectors. Start engine and check for leaks. That's it.

hope this helps good luck!

Remove the plastic cover over the top of the engine. on the passenger side of the intake plenum there is a senor (MAP Sensor). That sensor mounts to the top of the PCV cover. Remove the MAP sensor. Remove the cover and the PCV valve will be underneath.

The PCV valve (3) is mounted into the top/right side of the intake manifold (2).


1.The PCV valve (1) is sealed to the intake manifold with two O-rings (2).
2.Remove PCV valve by rotating counter-clockwise 90 degrees until locating tabs (3) have been freed. After tabs have cleared, pull valve straight up from intake manifold.3.After valve is removed, check condition of two valve O-rings (2). __________________

The PCV valve is located under the map sensor in a plastic housing. If you stand on the passenger side of the vehicle and look under the hood, the map sensor is the sensor right in front of you.

It should have three wires going to it. If you look closely, the sensor is clipped into a type of cap. If you grab the cap the sensor is clipped into and twist it counterclockwise, it should come off and the pcv valve will be inside. You may need new orings to prevent oil consumption. You may also need a needlenose pliers to remove the sensor from the upper intake manifold.

Hope help.

The pcv valve is usually located on one of the valve covers look for the larger vacuum hose coming from the intake manifold and follow it you should find it that way. changing it is a matter of sometimes using a pair of pliers to remove a small clamp then rotate back and forth the pcv valve while holding the hose and pulling it away and off.

1. BUY THE NEW PCV VALVE FROM THE DEALER. part #4648973AC (I paid $9.95 in the Detroit area). 2. PCV valve is located on top of 'rear' valve cover. There is a black rubber pipe connecting the PCV to the upper intake manifold. The rubber pipe is like an inverted 'U' shape. 3. To remove the rubber pipe, you will need to squeeze the band clamps. Remove the upper end first. You will then be able to rotate the lower end clockwise, if necessary, to get enough clearance to use pliers to squeeze the band clamp. Remove the pipe. 4. You should be able to see the small chrome pipe on the end of the PCV valve. However, the PCV valve is completely surrounded by a plastic collar/shroud, part of the plastic valve cover. So, the only part of the PCV that is accessible is the small chrome pipe. 5. THIS IS WHY YOU NEED TO BY THE NEW PART FIRST. I needed to clamp onto the end of the PCV pipe with VISE-GRIPS. This will crush the end of the pipe. You will hold the vise grips in a horizontal fashion, towards your right, in your right hand. 6. Rocking the pipe, while carefully levering the vise grips on top of the plastic collar, you will walk the PCV valve up, and out. BE PATIENT. You do not want to crack the valve cover! 7. The rubber grommet should come out with the PCV metal valve. If not, you will need to pull it out (needle nose pliers?). 8. Install the new PCV valve. I used a film of white lithium spray to help the insertion. Note, there is a groove molded into the rubber grommet that must snap into place. I used a 5/8" deepwell socket as a 'pusher', to ease the PCV valve into place (just push, do not hammer). You should be able to feel it positively snap into place inside the plastic collar, otherwise it is not properly installed and will not seal. If properly installed, you will not be able to pull it out by hand. 9. Install the PCV rubber pipe. Slide the clamps towards the middle of the pipe, fit the pipe over PCVvalve. Be sure it is seated all the way to the bottom of the plastic collar. Squeeze the clamp and work down to the bottom of the pipe, then release. Repeat for the upper end of the pipe and spring clamp. 10. Have a cold one. You earned it.

The PCV valve is not removable from the valve rocker arm cover. The PCV valve and rocker arm cover must be replaced as an assembly.

please rate as fixed if this helps.

4 cylinder

SECTION 303-08: Engine Emission Control 2003 Escape Workshop Manual
REMOVAL AND INSTALLATION Positive Crankcase Ventilation (PCV) Valve —2.0L Zetec Removal and Installation

1. Remove the PCV valve.
   • Remove the crankcase ventilation hose from the PCV valve.
   • Remove the PCV valve from the grommet by turning the valve counter-clockwise

------------------------------

It may be that the rubber grommet that the PCV valve plugs in to is aged and brittle, preventing the collar on the PCV valve from coming through. You may need to remove both the valve and the grommet and purchase a replacement grommet that is more pliable and allows the valve to be mounted more easily.

The PCV valve on the KA24E 4-cylinder is located in front of the oil filter and above the alternator. It points to the rear of the engine.

You will need only two tools; a stubby 19mm open end wrench and a pair of pliers to remove the hose clamp. I did it without removing anything else. Just reach around to the right of the oil filter. It took about 15 minutes. Here is a pic:
