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.

    to prevent tube from crumbling insert a small pin in tube before clamping with vise grip will make things a little easier

    Agree with everything mrmalba said, especially the 'patience' part. I had a strong pair of electrical pliers that gave me a firm grip and leverage. I used the same 'horizontal' position described and 'rolled' the pliers against the top of the valve cover. The PCV valve came out easily, but with only 1/2 of the rubber bushing. Maybe a 'back & forth' motion would have been better. The busshing had almost plasticized and half was left in the vavle cover. I couldn't get anything in there to pry out the bottom half. I used an 8mm deep socket & some 3" 1/4 drive extensions to loosen the head cover bolts. I was worried the bolts would fall in the back of engine if I didn't hold onto them as I removed them, but they are designed to stay in place and won't fall out(thank God). Slightly pried up on valve cover from right side front/back(best angles) and the gasket gave way. Carefully removed valve cover and was careful to not drop lots of **** on exposed valves. Then, using a small jewelers flat blade screwdriver, pried bottom have of bushing out. In hind sight, I shoudl have tried this w/o removing valve cover, but could not see it(oh well). Pushed new PCV valve in place with 5/8" deep socket. Carefully put cover back in place and tightened cover down. BTW - did not have to remove wiper assembly, and didn't have too tough of a time with it. Took about 1 hour total.

You must remove the valve cover so you can remove and install the pcv valve. Sounds crazy I know, but that was the only way we could get old pcv valve out and the new pcv valve inserted in. After trying to remove the pcv valve while the valve cover was still in place, we finally gave up after a few hours. A deep socket 8mm, a long extension and a swivel ratchet will get the cover off. Then we had to put valve cover on workbench and pry and pull on pcv valve to get it out. Then we finally got the new pcv valve inserted in the valve cover correctly. Then we re-installed the valve cover.....we never dreamed it would be so involved. Good luck!

What Poster #1 and #2 said were correct. I had to remove the whole wiper assembly because I couldn't get enough leverage on the valve to pry it out.
Honestly, I don't think it's worth the bother. Wait until you need to change plugs, remove the wiper assembly then change plugs wires and PCV valve. Be sure to google "I can't get my wiper arms off" because they'll surely be stuck as mine were. Good luck.

Location of pcv on 3.3 dodge caravan


Look for a large rubber tube attached to the manifold port located on the top left side (passenger) rising up and and then curving down to the rear valve cover pcv port. It is a squeeze, but work the hose off the pcv port, and "voila" the pcv valve is INSIDE the port. Pull it out with its attached grommet. Do not attempt to clean. Replace, only, and save the receipt for the engine warranty. This engine can burn oil if it is a valve seal or manifold plenum problem.

Pcv valve


I am assuming that you have a V-6 engine.

The pcv valve is located behind the intake about in the middle of the rear valve cover. Remove the hose that goes from the intake to the rear valve cover. The valve pulls out of the valve cover. Sometimes it is difficult to remove.
