Good to hear your back rolling again. Just hate the bad luck. Does the new motor have any more/less power than before?

I can understand some of what you're going through. My 7.3 has developed a problem that was diagnosed as #8 injector is bad. It won't take fuel as long as it is cold, shakes, rattles but no roll!! If I let it warm up to operating temp. it is fine and gives no trouble the rest of the day. It doesn't do this if I plug in the block heater overnight. It looks like I'm facing some big buck repairs also. It just seems like somebody always has their hand out!! LOL :xyxthumbs:

Apparently International has a service announcement addressing this very issue. Applied by them only to their I-6 engines. The Powerstroke uses the same type of injectors. This is what happens. Low fuel pressure, air in the fuel line (from any source) or one more cause that I can't remember since I closed the messege. This will cause the injector to not completly fill with fuel. When the hydraulic piston inside the injector fires it will slam the plunger inside violently to the tip and cause it to crack and/or break off. The plunger normally has a cushion of fuel to stop this from happening. With the fuel starvation, even once, the cushion is gone and its metal to metal. The announcement also stated that since it was not a defect in material or workmanship it is not covered by the warranty. He is replacing the fuel pump with a higher capacity and putting a pressure regulator on it to keep it from happening again. Sincerley hope this does the trick. I should get the truck back some time early next week. In the meantime, I've been driving the Bronco. I like the way heads turn to watch it go by.

Yea id say that bronco would turn a few LOOKS AWSOME by the way. I was watching ULTIMATE OFFROAD ADVENTURES the other week and they were doin a deisel challenge and one of the trucks (forgot the make) had the same thing happen to him he went to take off the line and alot of grey smoke rolled out and he shut it down they said it was an injector failed/broke he could not finish the challenge. Must be a common problem

Do you happen to know the specs on the fuel pump he's installing? Sounds like it may be a good upgrade if a chip is installed.

Hopefully you will never see this problem again.I had a '99 F-350 stroker for about 100k miles as well as several company trucks that we abused terribly.I was working in cell tower construction at the time and these trucks were treated like trash.The only consistant problem that I ever noticed was on the 95-97's there was an issue with the flywheel(they were always straight-drives)and on the '99-up the slave cylinder/clutch master cylinder assembly would take a shit at around 90-100k.My clutch fork came apart in mine at 110k and destroyed all kinds of expensive stuff.But as far as the engine I really don't think you can beat that 7.3.If finances ever allow I will own another one.Good luck with it.:xyxthumbs:

I'll get all the info I can. Like I said earlier my mechanic had never seen this happen. He did a lot of research on the internet and through his trainers/teachers/dealers to get up on this. Its not actually the injector thats a problem but the fuel delivery ahead of it. I'll see what I can find out about the pump when I get it back. He was nervous about letting it go without knowing what caused it.
