Default How the heck to change PCV

Ive been searching this site and the internet for a while now and just cant figure this out. I know the PCV is on the right valve cover but I cant figure out how to get it out. Also, there is a plug on the end of it that Ive never seen on any other car.

Any suggestions?

It is an electrically heated valve, which mounts into the cam cover with a bayonet style 1/4-turn twist-lock. Disconnect the electrical connector and turn it anti-clockwise to remove it.

That was too easy... Thanks again for the help. It seemed to be fine so I didnt need to replace it. FYI dont buy a PCV valve from autozone for this car. Its not the same one.

I have not seen the heated one at any FLAPS. Rock Auto has the Motorcraft valve (p/n 2C5Z6A666AA) for $25:



I find no mention of the PCM's monitoring the PCV valve heater so it is likely possible that you could run the unheated valve and just leave the electrical connection up-plugged.

That said however it has been my experience that the heated valves do not get anywhere near as gunked up as do the unheated units, so as was rodvandam experience I have not yet seen one that needed replacing, even at 180k miles!

Yea, Im returning the autozone valve and will let it go. The PCV valve is in good shape. I usually replace them when I tune up the car anyway, just for the sake of feeling more accomplished and the fact that they are usually cheap. lol.

Thats great information though. Thanks!
