I have a 2001 Expedition 4.6L 2V N/A. I have been dealing with driveability problems (see my other posts) that are from a lean condition. I am just getting back to work on this problem and have been shooting the parts cannon on hoses on the manifold vacuum due to age. I just replaced the PCV Valve with an OEM assembly XL3E-6C24-HA (with EV-233 PCV valve). As all know it is a PITA getting the rubber boot on the manifold. Thankfully my wife has small hands and she got it on in two tries.
So after I had removed the old assembly I noticed that in blowing through it from the manifold end (backfire mode) that the old valve sealed up quite tightly, while the new one allowed a lot of air to pass. I assumed the old valve had worn in and the pintle seated fully, blocking the inlet. This was not a very scientific test, just me blowing into the hoses and comparing. The old and new valves rattle. I doubt the original had ever been replaced since I bought it with less than 24K miles. I cannot read the markings on the original valve. The assembly is F85Z-6758A (or so it appears).
Did I buy the correct valve? Is the valve OK with leakage in the "backfire mode"? I see a lot of people discussing this on line with other vehicles. I would hate to have to remove and replace this again. My wife won't be happy certainly.
EDIT. I have a VIN "W" (Romeo Engine). According to fordpartsgiant I bought the correct PCV assembly/valve EV-233. However the part factory installed seems to be for an earlier model, maybe Windsor engine?
