What they said ^^^^^^^^

Clean the area then drive it and see where it's coming from.

FYI... DO NOT throw out the old PCV valve until you take the elbow off the top.

Should I assume that the new PCV Valve will have a new seal? It looks like it just screws in with two screws. That is different than all the other V8's I have had. They just pop in and out.

The PCV and the retainer are two separate parts.

Great thanks! Should I just replace the PCV too? The car just turned 76k miles.

Can't hurt if you have never replaced it before. They usually run $10-12 I think, can pick one up at the local auto parts store or at Ford. The crankcase retainer is a dealer only part though.

I just flipped the o-ring over to sto the oil and its still holding up 10k miles

Any idea what the part number is for the PCV?

The valve itself? You can pick one up at any auto parts store. It's a wildly used part among several Ford models so it should be in stock. I picked mine up from Napa.

Ford p/n is 2X4Z6A666AA for the PCV valve.

I figured I might as well order the retainer gasket AND the PCV. But, after some Google searching, I could only come up with 2L3Z6A666AA. That says it fits Marauder, but, also C-Vic, Explorer, Town Car etc which leads me to believe that might be for only SOHC engines not DOHC (like it says). The part# you posted says all DOHC. That makes me feel better (plus its $2 cheaper, LOL).

Thanks for the info. It's happening to me also.
