Hunting season is winding down and no grass to mow, so I finally have time to dedicate to this project. Started disassembly of the low mileage 7.3 that had the cylinder head with rust hole. Pulled both heads and the cylinder walls look great.

Judging by the cross hatch in the three cylinder that show, it looks like it's barley been ran after the cylinders were honed.

I know the fella who bought this truck new, I bought it from him as a parts truck. It had around 130,000 miles on it. He used rotella oil and changed regularly. It looks great on the inside and terrible on the outside. Plow truck with tons of salt exposure. I had to drop two wrench sizes on the head bolts that were not under the value covers. And over course don't forget the cylinder head had a hole rusted through it.

I still find that crazy. I'm not doubting it at all, but I just can't imagine that. It's completely beyond my experience.

Salt and salt brine they put on our roads are very corrosive. I hose down underside of our vehicles with diesel and motor oil mix. Also squirt regular motor oil inside the doors till it comes out of the weep holes.

Finally got the engine cleaned up and torqued the heads down. New o-rings on the injectors next.

Replaced all of the o-rings on each injector and installed. Also installed rocker assembly and push rods. Last photo, this was on two of the injectors. This engine was never disassembled from new so not sure what it is???

Where were they on the injectors? Looks kind of like an oring was sheared during install and the sheared part was squished by the body for years

Makes sense. Both were on the "stem" / "shaft" (not sure what the proper name is) between the bottom o-ring and the one in the middle. One injector on each side of the engine.

More cleaning, does it ever end! Valve covers, dog box, and lower rad fitting bead blasted and acid washed. Next they get painted with high temp POR 15. Also swapped out the hard fuel lines to new flexible. Getting close to dropping this thing in....

Clutch comparison. Top center is what I bought to install. Lower left is South bend from the crewcab (note it has one broken spring and one missing). Lower right is factory original from the parts / plow truck. Comparing all note the different designs, specifically size and number of springs as well as the width of the contact area on each disc.

I’m sure you already know this, but Southbend can rebuild that clutch. It looks like the one you bought is pretty heavy, but you can’t have too many spares.

Thanks, I was not aware they are serviceable. Just about have the engine ready to drop in. Replaced a ton of parts. I'll take a few photos before it goes in. It has been plenty cold here so lots of guilt free garage time.
