I just cut a quarter down to do the 50cent mod and the quarter would only go about half way down and as I looked closer there is a little plastic chip at the bottom of the connection on the harness. Is this clip the international repair clip ??? Does anyone have a photo of what this clip looks like. I can't post up a photo myself.
Now should I just leave these little wedges in or do the 50cent mod ? Or do both and cut the other side of quarter ??

If you had the shim in place, you would be able to remove it and the quarter wouldn't even begin to slide into place.

There is an updated harness that is available that is supposed to do the same thing as the clip or quarter. The quarter with the top trimmed down doesn't fit in the updated harness. Search for a post by Kwikkordead about how he modified a quarter to fit in the new updated harness.

I also found that the injectors were all loose but like you said earlier about the o rings makes sense. Rockers too needed alittle torque about a 1/4 turn.
I would have sent reps for this tread but I got the "Must pass them around" I hit you up when thI am out of rep jail. Thanks for your input

One of the known issues with our trucks is a loose UVCH (Under Valve Cover Harness) connector. If this connector comes unplugged a little, it looks like this.
Since that plug connects the wires going to the fuel injectors, when the plug becomes loose, the injectors on that side stop working and your nice powerful V-8 Powerstroke becomes a 4 cylinder.
International (who made our motor) realized this was an issue and developed a plastic shim that slides under the locking tab to keep the tab engaged and prevent the connector from becoming loose.
Turns out a US Quarter is the correct thickness and width to act as a shim for this connector. The top of the quarter has to be ground down so the valve cover fits back on, but add a quarter to each side like this
And you've just invested 50 cents to keep your truck running well. Hence the 50 cent mod.
Also, if you pull the valve covers, then you should also re-torque your rocker arm pedestal bolts, circled in red, to 20 ft-lbs
and your lower injector hold down bolts, circled in blue, to 120 in-lbs, note that's INCH - lbs. They tend to work a little loose over time and the engine sounds much better after you tighten things up (unless you've got a tuner).
