Pcv Valve Question

pics please

There's one with the pre-heater element, if your car doesn't have that one in already you live in a fairly warm climate and don't need it. There's also the chance that you aren't looking at the PCV, is the one you're replacing hollow? If so (and I did the same thing) then check the other valve cover

Model year?

Might be handy to know the car's year. The PCV system was redesigned in 2001. The PCV valve itself has a larger tube and a different attachment to the valve cover.

Yeah autozone sucks balls. They carry the pcv valve for a 5.0 liter and list is as the part for 99-04 as well. The pcv valve you have has two plastic ports on it and the one we use only has one. Take it back for a refund, they don't carry the one we need. Go to your local stealership and get one.

I would suggest teamfordparts or rockauto dot coms for small OEM type purchases in the future. Their online catalogue is pretty good at selecting the appropriate parts and usually show the comparable Motorcraft part number next to the knockoff if they don't have the OEM in stock.

Most generic auto part store PCV valves come with two ports, it also comes with a plug to plug off the unused port. The only way to get OEM is go to the dealer. I just bought one for my 96' from Advanced Auto Parts. If I'm not mistaken, it will also fit the 5.0L too.

Get a copy of the FRPP catalog while you are at the parts counter OP.

Just stop by a dealer and get the correct OEM valve. It's cheap. I think I paid $7 for the valve on my '02.

It's not that big a deal. Just plug off the unused port - there should've been a plug in the package just for that purpose. If it bugs you that it doesn't look original then go to the dealer and grab one. The Autozone one will work fine though.

Yeah I do not think the AutoZone one will be as good. But I agree there should be a plug you could just plug it. But expect to replace it sooner.

i honestly had more trouble withe the ford one, the autozone one would use less oil then the oem ford one.....

A Little More Info for Future Readers & Those Watching This Thread

---The new style PCV valve works for a broad range of vehicles, including the 2.9L i6 IIRC. The P/N is assigned by the amount of vacuum needed to move the pintle and not simply the OD of the barbed fitting, grommet end, threaded end, etc., per application. Since the grommet end is the same size on most, and vacuum required for operation is the same, rather than make 4 or 5 different packages, train people to work the line differently, change laser jet for printing cases of parts, etc., one PCV Valve is made & it's up to you to make it match your old one.

---In between the 3/8" and 5/16" nipples there is a plug. Twist the plug off and insert it in the 5/16" nipple if the 5/16" nipple is unneeded.

---The plastic Tee and steel PCV Valve are separate. You can pull the Tee off the PCV Valve for use on the 5.0. BTDT.

---PCV Valves very rarely go bad and unless the valve's casing itself is plastic (like most cheap-o frams), there would be no need to replace it regularly. Cap off one end with a thumb, spray carb cleaner or similar solvent inside it, filling it half way, cover the other end with finger and shake "watch yourself" (eye protection). Some PCV Valves carry the same P/N they did 30 years ago and some 30 year old PCV Valves are still in use.

---The wire mesh filled "looks like a PCV Valve", if the 4.6 has such an animal, is as much not a PCV Valve as it was on my IHs from the 70s. PCV Valve's main job is to stop vacuum to prevent ignition of crank case gasses when under load and backfire occurs. That would be a breather element, and if a hose is hooked to it, running to/around the cold air intake, that would be a flame arrestor (see marine parts) of sorts. It is, simply put, the other end of the Crankcase Pressure System. The wire mesh can be cleaned with the same solvents as the PCV Valve, in the same way.
