Where is the PCV valve on 2000 2001 v6 DOHC 24 valve Taurus?

Answer 1

Ford Taurus PCV valve locationOn my 2001 Ford Taurus SEL, 24 valve, DOHC engine, the pcv valve is located not where you think it would be. The best way to tell you how to locate it is to follow one of the largest hoses (it's not big...probably 3/4 i.d.) coming out of the throttle body and follow that down to where it mates up to the pcv valve.

To help locate the hose, it will be underneath the throttle body and will have a grey hose clamp. The hose will also form an "L". It also turns to a plastic hose too, if that helps. So... rubber "L" hose to plastic hose back to rubber fitting, then the pcv valve.

Another description...The pcv valve is on the driver's side of the car, in the top-middle of the engine under a wiring harness and close to the fuel rail. Naturally, Ford put this next to a lower radiator hose entering the engine block too. In all, it's in the worst spot ever for a pcv valve, if you ask me.

To access this, you really need to remove the whole plastic intake and throttle body. Maybe a professional mechanic could do it without doing this, but I'd have to see it to believe it.

One more thing I forgot to add. The pcv valve for this is made by Motorcraft (part number EV-243 or part number EV-268) EV-268 has a metal hose wrapped around the part. I was told that on some Ford minivans, the metal tube is for coolant to run through.... I guess to keep the valve cool. Anyway, you won't need this for your Taurus. Simply bend it slightly and pull it off. The valve, you'll notice, has square-like sides. This is to allow you to put a pair of pliers on it to remove the old and insert the new. The part has to be turned about a quarter turn counter-clockwise to remove and the opposite to install. You'll also see that it has a rubber o-ring on it to seal it in the block. You won't be able to reach it well with just your fingers, unless you were to remove the wiring harness and fuel rail. So... simply use a pair of pliers to reach under the wiring harness and grasp the square-sides of the valve and twist it counter-clockwise to remove. I didn't need much pressure at all to remove it, although I read online where one guy's cracked when he did it. He claimed it was in there so long that the piece was seized in the opening. Mine simply twisted out and I twisted the new back in.

AnswerIt is below the egr valve close to the intake manifold below the intake air sensor, there is a tube running to it from the engine to recirculate exhaust air with fresh air, there is a clamp holding it to the air intake that you need pliers to remove, then you need to turn counter-clockwise 90 degrees to remove, do the reverse to install. to make it easier to access remove the upper intake. The pcv valve is not visible, however, you can identify it by the 3" inch long rubber hose that connects to the steel line running into the bottom of the intake. I have the part and am going to replace it soon, although Ford really makes it difficult to remove it - pcv valve is located just under the throttle body. remove air cleaner assembly from throttle body and you will see a u shaped hose running horizontally. Answer:My 2000 Mercury Sable with a 24V DOHC 3L Duratec tripped the diagnostic trouble codes P0171 and P0174 (system too lean banks 1 and 2). I pulled off the 2 rubber elbow boots on the vacuum lines leading to the air intake covers and they were deteriorated (ripped apart as I removed them). Although they were 90 degree angle boots, I replaced them with 45 degree boots I found on a Taurus at the junk yard. The "check engine light" came on again on the 3rd trip. Ran my finger under the barely visible rubber elbow on the vacuum hose under the housing containing the MAF sensor (I presume the hose leads to the PCV valve) and felt a split in the rubber. To avoid the hassle of taking off the air intake manifold, I wrapped that section of hose tightly with electrical tape. I erased the codes with my scanner and haven't had a problem since. My next steps would have been to check the EGR valve and sensor, DPFE sensor, PCV valve, and air intake manifold gasket.

under the air intake on the drivers side

follow the pcv valve tube from under the air intake manifold

down to the left

i found mine and removed it with a 22mm deep well socket

after removing the wiring loom plastic screw and the plastic shield about the throttle cable to gain hand access

the pcv valve turns 180 degrees cc wise and pulls out

good luck

2003 Taurus SES w/DOHC 3.0L V6I was doing a tune up and had to remove the upper intake manifold to access the coil and rear bank of plugs. Since I had the upper intake off, I changed the PCV valve. However, it may be possible to do it without taking the upper intake manifold off.

The PCV valve is located underneath the injector wiring harness and next to the coolant hose. All of this stuff is underneath the upper intake manifold/throttle body assembly. The PCV valve is mounted horizontally and sticks out toward the driver side front wheel. It has a straight rubber hose about 3" long that completely covers the PCV valve so that you cannot tell what it is. That 3" rubber hose connects to a black plastic tube that runs out of the gallery underneath the injector wiring harness and turns toward the throttle body. There, the black plastic tube connects to a molded rubber elbow that is clamped to the underside of the throttle body.

That molded elbow and black plastic tube are distinctive and will lead you straight to the PCV valve. The black plastic tube easily pulls out of the molded rubber elbow as it is not clamped. Follow the black plastic tube under the gallery and just pull the straight rubber tube that it attaches to. It will easily slide off the PCV valve as it is not clamped there either. At this point you will be holding the black plastic/straight rubber tube assembly in your hand and the PCV valve will be clearly visible (at least it was with the upper intake off).

The PCV valve is sufficiently tucked into the pocket formed by the injector wiring harness and coolant hose that you can't really get pliers in to turn it 1/4 turn CCW for removal. The injector wiring harness is fairly rigid and you cannot move it out of the way without removing the injectors. However, it is not as bad as it sounds. The PCV valve has a square flange on it that is a perfect fit for a 7/8" deep well socket. Put that socket on an extension and it makes a nifty PCV removal/install tool. You may need to use a ratchet handle to turn the old PCV valve out if yours is stuck, but mine came out easily. I stuck the new PCV valve into the socket and inserted it by hand into the recess and was able to give it a 1/4 turn CW with just my hand turning the extension. I slid the black tube/straight rubber hose assembly back on with no issue and finished my tune up.

If you attempt this without removing the upper intake, then I assume you will have more difficulty, but it may not be that bad. The 7/8" socket and extension work excellent as a PCV removal/install tool, so it may work well enough to allow the PCV to be replaced without removing the upper intake. It's at least worth a try.

AnswerIt is not external on the 8 cylinder SHO. If you have the "P" Vin engine (32 valve) then you will not find a positive crankcase ventilation valve on it. Ford does not recommend servicing it.

Answer 2

It is located underneath the throttle body.
