Question about 2002 Mercury Mountaineer
You didn't say whether your engine is a 4.0L v6 or a 4.6L v8 but if you have an excessive amount of air blowing back into air box and vehicle is running good otherwise you may have a stuck open PCV valve causing it to pull to much vapors from engine crankcase.
If it is a 4.6L it will be located in the valve cover itself.
If it is the 4.0L locate the hose coming off of the back of the upper intake and it will be at the end of this hose. This one you twist CC to remove.
