I just realized something the above posts say the PCV valve is on the right side behind the air cover which would make it to the left of the spark plug distribution cap. Sparkies picture shows it on the passengers side to the right of the EEC-V control module.
Which side is it on the driver side or passengers side? Lots of those hose configurations look the same back there??
Right left, left right! The pictures are correct. Its on the right side or "your" left when facing toward the rear of the engine. Just remember passenger side...driverside when trying to orient yourself as to where components are located,
I think this why so many folks have a hard time finding that little do hickey. I assume the hose layouts are different from year to year and then vary in SOHC and OHV engines. Hell it might just be what day of the week, time of year or the plant the EX was assembled! I also noticed the location of the IAC valve is also different for some of us. There are many threads about cleaning it and removing the black cap to stop rough idling and the whining noise, most pictures and diagrams ive seen show it on the driverside of the intake manifold. On the 99XLT 4.0 SOHC it's dead center on the top toward the rear, and the black cap isnt removeable. Manuals arent much help either, they usually have generic diagrams of where components are or should be, they arent revised to the design changes the manufactures make while the vehicles are in production, I guess that makes sense from the publishers point of view, imagine having to revise and print whole manuals for everytime the manufactuer makes changes which could be hundreds for every model!
Sparky and Diddy are both correct, on all 1998/2001 SOHC V6 engines, the PCV Valve is located PASS side rear of valve cover.
Vertually all modern day ford engines have the PCV valve mounted on a valve cover.
In 2002 ford came up with a new water cooled EGR system in turn (so they say)
lowering temp of gases going thru the PCV valve and entering the plenum just after the TB, is said that it lowers emissions and may increase performance.
Thats when the PCV valve was moved to the DRIVERS side rear of the valve cover.
So if you can locate your valve covers, with a little looking, feeling etc, you can find the PCV valve, in some cases they are a PITA to remove (like spark plugs on the EX).
But they are a servicable item, meant to be removable.
Why ford in there infinate wisdom made them a PITA to service, is a whole diff, debate.
Just my two cents
Most likely it's because the automakers figure the average driving citizen isnt mechanically inclined or doesnt have the time or paitience to do simple to moderate maintainance and repairs. They would prefer us to get serviced at their dealership service centers and buy their parts! $2 part @ autozone or any parts chain. $45 dealer service dept! :fire:
Thanks again for the advice. I can finaly put this thing to rest once and for all.
Wouldn't it be great if someone came up with a car that was user serviceable. You could easily and quickly get to all the serviceable parts and fix them.
I have been seriously working on my Sport for about a year and a half after the dealer screwed me one to many times. It is very evident that Ford and other dealers make it very hard for someone to service there own vehicle i.e making parts that break off easily, neglecting to inform people in manuals that removing something with the slightest bit of incorectness will destroy it, locating bolts and screws in the oddest places, putting safety torx and loctite on parts for no good reason. All BS- and even when you ask the dealer for parts they frown and get pissed because they know your doing the job yourself.
Oh boy I screwed this up. I fished around with my hands and pulled the T- connector out of the holder that the PCV valve went in trouble is I can't get it back in to that rubber hose. Is it in fact supposed to go back into the small rubber hose sticking up??
At the present time I have the T connector connected to the PCV valve but the valve is not connected to the rubber tube, I have been driving it like this with no problems. Though I do believe it will have to be re-connected come inspection time.
I used to own a Toyota MR2 Turbo and one of the performance upgrades was to plug the inlet hole for the PCV tube that went back into the intake tube and put a breather filter in the crankcase vent end. This increased performance by not letting uncombustable oil and vapors back into the engine. Maybe it will be effective on the explorer as well. I know it is not emissions legal....
Anyone with information as to if the PCV valve needs to be connected or how to connect, would be greatly appreciated.
The MAF will not read properly if the PCV breather is allowed to take in outside air. i.e. the air that comes through the breather will not be seen by the MAF.
Probably need to warm it up and make the rubber pliable again.
I have been looking for 2 days on my 97 5.0. Can anyone give me some direction? I have tried feeling around with no luck. It is behind the intake manifold right?
I noticed there seems to be a plastic zip tie type thing around the rubber tube that the PCV valve mounts in. Should this be taken off and replaced as it seems that it is there to hold the old one in place. It seems to be constricting the tube a bit making it much harder to push the new PCV valve in.
After the new valve is in do I need to intsall a new plastic type zip tie to hold it in place?
I am halfway through this job and could really use some advice from someone who knows...Please Help
Come on guys, I am in the middle of this replacement and need to finish the job. If anybody knows anything about a zip tie that is around the rubber tube the PCV goes into I would love to hear from you.
It seems logical that the plastic zip tie would hold the valve in place but I am not sure. Can I just cut it off and use another zip tie? Is it even part of the PVC mount?

Well once I found it after diggin in every nook and cranny in the engine compartment, under the engine, the wheel wells, the glove compartment etc. I finally found it, and after all the blood sweat and tears to get it out, I replaced the valve and left it as is. Its also much easier to access that way. If you must I guess you can use something to secure it back down there.
I of course was joking, but hook up the hoses to the valve before you put it back down there into engine oblivion where many components mysteriously live. We cant see them but we know they are there!
Diddy did you remember cutting that plastic zip tie thing off? Maybe it isn't even for the Valve but to hold wires in place. I can't see that good into that area.

Much obliged, I basically just pulled it out of whatever had it held down. I might have broken it to get leverage during the epic battle to get the hoses off, by then I didnt care anymore. I was pissed about cracking the T connector trying to get the PCV valve back in place. So far I havent had any problems with my "improvised" hose connection or just having it "hang loose"
Dont want to get off topic, i'm assuming your front sway bars are similar to the 99 xlt, what size poly bushing did you get? Local parts store started carrying energy suspension products but I couldnt get a straight answer about which size would fit, apparently there are differences in sway bar diameters on different Ex models. I should stop being lazy and get down there and measure but its been cold and nasty. Its alot easier to type!
Sure its 34mm, but don't get just the swaybar bushings do the end links as well- you have to take the Sway Bar off completely anyhow. You can get the kit for about $25, I got the red ones
