99 Powerstroke ticky-tick

[sparkchaser]

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.

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:
