Heres an easy one. Where is the PCV valve on my 94 f150 6 cyl. Thanks.

 

pop open your air box lift up the air filter and walah! there it will be, and on the outside of the air box is a small tube where the air runs through

 

The PCV Valve is located at the back of the valve cover . The PCV Filter is located in the air filter housing , under the air filter .

 

I just went through that--took me a while. It is practically hidden under a hose that runs across the back of the valve cover. If you kneel on the cross member above the radiator and then reach down just behind the intake plenum, you will find it. But why does the valve have two hose fittings and you have to plug one, when I see single hose PCV valves all over the rack?
