Where is the PCV valve on a 2002 Sport Trac

[acopel1]

I have looked everywhere and I can't seem to find the PCV valve? Can anyone help?

located at the back of the intake,about 4 inches from the top,just right of center.you might have to crawl up on the engine with a flash light.there is a retainer that holds it to the intake.

when you have it off, if it rattles thats good. if no rattle then you need a new one
