Just noticed that something called the "crankcase emission air filter" should be replaced at 30K mile intervals. What is this and where is it located? Can't find a reference on my service CD nor the Haynes manual. Appears to be unique to the 5l engine.
You could check at the back of the intake manifold. I don't know if its there, but I seem to recall something is back there.
It's UNDER the PCV valve at rear of intake.
It's actually an oil separator and gets clogged, should be changed every 30k like they say.
Many advocate using large long sheet metal screw as a "grabber" to pull it out.

Thanks for the link. I'll pull the PCV and replace it. I wonder though, why ford calls a screen an "emission air filter".
it's defintely there. I used to own a 95gt. It's way behind the motor. You really have to lean in to see it. I think you need to pul a hose off of it first. It's easy to get out. A needle nose set of pliers will easily get it out.
