PCV location and removal help - 03 ZTW 2.0l zetec :(

I am going crazy this morning trying to figure out how to check my PCV thingy - for bad idle problem I am having.

I have searched forums and watched videos and consulted my repair manual...

Seem fairly obvious from these sources that the PCV valve goes into the motor at the end of the hose that goes from the air filter box... ok. So the little tube that the hose is on, according to the videos I watched, is supposed to rotate a little and slip out and that is the valve I am supposed to shake and see if I hear a noise to tell if it is good. Right?

That thing will not budge and it looks to me after scrubbing around the area that it is attached to the case and not a separate piece at all. I don't know what to do!

Could someone take pity on me and help me find a link to a video or even an image that shows this thing? I looked at the how to change pcv hose here on the forum already - that is not my same engine but...

I just can't think any more - please help! I am going to cry or throw up or bash something with a sledgehammer any minute. LOL It does not seem like it should be this hard to check this thing - I must be doing something wrong.

The pcv valve on these zetec engine is done next the the head, not in the valve cover, it is really common for the rubber elbow from the valve to the metal tube to rot, and for the hose from the other end of that tube to the underside of the intake to rot as well

The PCV valve for the zetec is located about 10" below the oil fill just to the right of the exhaust manifold.

Be aware that the other end of the PCV hose is a very common failure point. As the hose turns to go into the intake manifold (this is just below the throttle body), it often splits open or will collapse there. This can cause the engine to idle poorly or die.

That's it, but I find it much easier to get at from the top...no need to jack up car.

I just noticed that you live by Boggy Creek. Cool.

I have a pair of very long curved needle nose pliers that worked well to remove the valve.

^^^ Yeah, maybe he can get a local Sasquatch to come jerk that thing out for him. :-)

The rear PCV hose goes from a metal tube that runs under the coil pack to the intake below the throttle body. Very hard to get to the end below the throttle body...and don't break off the plastic intake fitting when you take off the factory clamp. Look at the clamp here PCV hose
