Yep, on my 2006 it's on the very rear of the drivers side valve cover. It points straight rearward and has a coolant line wrapped around it.
btw, Its cam locked in. Meaning you have to turn it to remove it. Kinda like a oil fill cap.
btw2, It's a real pain in the rear to remove. Just take your time and it'll com out w/o damage.

The EPA made a rule that says the manufacturers either have to put a positive retention device on the PCV valve or they have to monitor the PCV flow rate with OBDII. The screw-in PCV valve with the clip is easier/cheaper. I agree that the location on the 4.0 makes servicing the PCV valve just that much worse.

Is this considered a $5 yearly replacement item like on older motors?
You don't have to undo the coolant line and get coolant everywhere do you? I'm guessing the valve slides out of the white coolant line?
and FYI. On the Ford 2.3L Duratec (at least Focus 03-07 - not sure about Ranger or 2.0L Duratec) The intake manifold needs to come off to replace the $12 PCV valve. So this one is the new "easy".

The Ford service interval for the PCV valve in cars and light trucks is 100,000 miles. I haven't replaced one in years. We have several cars in my family ranging from 28,000 to 116,000 miles and they all have the same PCV valve in them that they came with.

the reason i had to know where the PCV valve is on a 2007 4.0l is so i can figure out how to install one of these: http://cgi.ebay.com/ebaymotors/Excel...spagenameZWDVW
i noticed the vacuum line comming off it is plastic. how can i modify it to make this work?

I think the money would be better spent if it went toward regular maintenance. Besides, I wouldn't give $30 for a device that is probably nothing more than an off-the-shelf $8 airline water trap.

Yes, you do have to undo the coolant line. If you do it when the engine is cold, there is very little loss of coolant. The coolant line that wraps around the PCV vavle is not removable, at least not easily, and it comes with the new PCV valve (not cheap).

Tell ya what I've done for many years now. Every 10k to 15k miles I take it off and spray the inside with carb cleaner. Just do that til clear fluid comes out. In the last 20 years I've bought only 2 pcv valves. One was jammed shut and the other was for a new motor.
btw, you don't have to remove the water lines to clean a ranger. Just hold it away from the valve cover a little and spray it out with carb cleaner.
