For some reason, I think my truck's 4.0L intake tube is missing something. The reason: It's a hole in the tube on the engine side with what looks like a mounting surface. Also, it's bringing in unfiltered air, so it has suction. The truck seems to run smoother when I plug the hole, runs kinda rough when the hole is open....WHAT IS IT???? And what does ya'lls look like??

Thanks in advance,

Shane

Here's the pic:

 

Does you truck run funny...

 

air temp. sensor, should be..should plug right in

 

Here's some pic of mine intake tude

 

better plug that tube right in, it's essential.

 

ha thats crankcase ventilation... yea u need to find that hose and reinstall it... if u dont have it, im sure i have a few lying around

 

So...

got any updates

 

That would be your Positive Crankcase Ventilation (PCV) Tube that should plug into the hole in the intake. Your crankcase is venting oily residue into the engine compartment, while the intake is sucking unmetered air. Plug the intake hole, and get a new tube from Ford. It's not a good thing.

 

was that directed towards me?

 

haha thats probably not good

 

I know that spot on mine is filled by the air temp sensor - check around that area for it.

 

The SOHC's had a vent coming off the RS valve cover going to that...

 

 

lol
okay

 

did you get that fixed yet?

 

He offline...

 

Hi ya'll, for some reason i could n't find this thread....

I bought the truck Nov. last year, put on over 12k sincethen and have no pic of this thing being on the truck. Never has been on since I've owned the truck. Now since I have the weekend off, I'll dig around the right side and hopefully find this thing. I'll let you guys know.

Yes, the truck has never run really smooth, I've had the usual '01-02 timing tick/ching, Slave cylinder going out, and for some reason in the morning I have the problem of needing to push on the gas before it dies, almost like I need to worm it up like my chevy. I'll explain more later, g2g.

 

your running problems will be fixed if you put that pipe back on!!!!!!!!!!!!

 

I looked all over my engine...found nothing. Including the rubber 90 degree off the valve cover. Does ford have them?? Or does anyone here have one I can buy off ya??

THANKS everyone.

Here's where there should be something better pic.

 

this is sorta what your looking at. instead of buying a tube, try a piece of hose u got laying around if you can

 

Don't offroad in the mud without it. Where the PCV breather goes into the cover on my 3.0, it's coated in mud much of the time. With that off, you could have all kinds of crud in your engine. Also, water will be getting in there when it rains. Not at all good.

Junkyard is another possibility.

 

I think i have a couple of these if you cant fit a hose over it... Just email me

 

Alright ya'll....if i am able to get out of the house tomarrow(snow/ice storm), I'll pick up some hose and try it out. If I have problems, Nick I'll be taking to you.

 

no prob...

 

I managed to get it at the "new-car junkyard"....My friends dad works there, He picked it off one of the disassembled engines and I paid him a couple burgers. Now I've got the part...thanks guys for all the help. Time for wheelin'.
