LOOKING IF SOMEONE KNOWS WHERE THE IMCR VALVE IS LOACATED ON A 2000 F-150 V6 4.2 LITERS. THE CHECK ENGINE LIGHT IS ON AND THE CODE IS 1518 AND I HAVE RESEARCH THAT THE IMCR VALVE IS PROBABLY STICKING FROM CARBON BUILD UP.

 

sorry, cant help you, my IMRC was fixed under warranty. i looked in the Haynes manual to try to find it- useless. try a Ford manual from the dealer.

 

It's near the center of the intake on the back side.

 

Had code 1518 on mine. Found that the nylon busching had come off of the linkage rod that runs between the module and the front bank butterfly valve. Looks like an old fashioned carb linkage.

It Cost less than $4 for a pack of the buschings and less than 10 minutes to fix (once the engine cooled down).

 

There are (1) on the back of each head! I fixed mind with a plastic dry wall anchor,small type,cut it off to about 1/4 " pressed itinto place then pushed the rod into it,still working and if it falls out then I go to the auto parts help section.

To illustrate, from my 2001 4.2L V6 after I removed both halves of the plastic intake manifold plenum:

2 of the 4 bushings and portions of both linkage rods can be seen. However, getting to them with your hands (unless you have tentacles instead) is quite difficult.

 

Glad you posted the picture. It was sort of a bear to get to. I used needle nosed pliers. Since the original post, I've had to do the same repair on my wife's 2001 Windstar 3.8L. It, too, was a bear to get to but really an easy fix. I used the buschings that were from the same pack that I bought for the truck.
