Explorer Air Filter And PCV
Q. Hi Vince, I read your article on "How to change your Air Filter", but am still having trouble locating it in my car. I have a 1994 Ford Explorer Sport. Can you direct me to an site that has a diagram of my motor? Or do you by any chance know where it is? Do I need to get to it from underneath? And, will I find the PVC valve in that same location?
Thanks for your help...
A. It is the large box on the right side of the engine. There is a large hose going from the box to the front of the engine itself. Here are specific instructions for your vehicle.

Cleaning of the positive crankcase ventilation valve is not recommended. The positive crankcase ventilation valve should be replaced if needed. Shake the PCV valve and carefully inspect for splits or cracks. If the PCV valve does not rattle or is damaged, replace it.
