Its on the very back side of the lower intake manifold.
Easiest to just take off upper intake to get to it.

Replace everything.......... grommet, screen filter and use Motorcraft PCV valve.
you could probably get away with re-using the grommet.

If you don't want to take off your upper intake, just look around the driver's side of the intake, underneath. You should see two hoses running from a fitting on the bottom of the upper intake--one hose goes to the front of the intake, and the other goes to the rear. The one going to the rear of the intake is attached to your pcv valve.

how often do you guys think the pcv valve should be checked/replaced??? what are the symtoms of it needing to be serviced?

I would go with the interval recommended by your manual--regardless of whether the valve still rattles or not. As the spring weakens, the flow rate changes.

Here you go......



Suggested PCV replacement cycle every 60k miles, filter element every 30k miles....I usually do both every 30k miles anyway.
