How do i replace the pcv valve on a 2000 explorer xlt v6 sohc?

On the passenger side of the intake manifold, coming off the bottom about the center of the engine front to back, you'll feel a hose that comes off a nipple. That hose makes a 90 degree bend and goes around to the rear of the motor. Where that hose meets the Y-connector from the other side of the intake you'll find the PCV valve. It's almost impossible to see it with the hood installed, and even tougher to reach it.

A good source of information for Ford Explorers can be found here

The correct location of the PCV for the 2000 Ford 4.0 Explorer SOHC v6 engine is the rear of the engine on the passenger side. You can pin point it by following 2 hoses, one on each side, that go from the middle of the air intake manifold to the same point..the PCV valve. The driver side hose is routed from the PCV around the back and comes up by the coil pack and toward the middle of the manifold (the connector faces rearward). The passenger side hose not as long and also connects to the plastic intake manifold.The hoses converge on the PCV with a plastic T. The arms of the T are connected to the 2 hoses and the bottom of the T fits over the PCV. There are no fasteners for the hoses or T, but will be difficult to remove either the tubes or the PCV from the T. Pull straight up and be cautious of the PCV nipple because it cracks real easy, the T is made up of hard plastic but take care to grab both sides of the T when pulling up. Once you have freed the PC V of the hoses (T) you will need a light to see the fastener that holds not only the rubber tube that holds the PCV but traps the PCV valve also so you can't just separate it from the tube. The fastener that wraps and holds the tube and PCV valve is a ratcheting type connector. Towards the firewall side of the fastener, you will feel a loose piece of the fastener on the outer part of the connector. Pull this towards the passenger side (towards you) and with a small screwdriver or pick, unlock the teeth that are meshed together. You can either do this on the end where the loose plastic piece stops or on the other side of the clip. You are just separating the ratcheting strip from each other. Once you successfully removed this clip (congratulations), you can begin to try to remove the PCV from the tube. I tried twisting and rolling the plastic down the valve with no luck. What I did find that worked was forcing (massaging) the PCV valve out from the bottom of the valve while it was in the tube and pulling from the top at the same time. Now one thing to note, this part has been discontinued and the replacement is metal, about a dollar, but you will have to modify the replacement by grinding any steps in the valve connector. The hard plastic T does not expand to fit a barbed end and that's what the replacements have. You might be able to replace the T with a more suitable rubber one but I haven't done that...yet. Now to see if the modified PCV valve will fit on the T.Hopes this helps. Hit helpful if you would so I get notified. Thanks, Bill
