IP's and injectors
Can anyone point out to me where Ford or International recommends changing the ip and or the injectors at 100,000 miles.
I keep seeing this pointed out everytime someone has any problem at all.
I have seen ip's fail at 50,000 and seen them make 200,000.and still be performing well..
I have seen much more complicated electronic injectors in big trucks go well over a million miles, and then only the failed one replaced.
I would like to see where the manufacturer recommend a change interval. as I think the interval is directly linked to the fuel you burn and and how well the fuel system is cared for.

thats a good question.
in Mel we trust.
These parts, generally speaking, are medium wear items, and typically last about 100,000 miles. The main factor determining the lifespan of these parts is the quality of the fuel being used in the vehicle, and any additives that are being used. Due to the high tolerances inside the injection pump, a supplemental lubricity fuel additive is always recommended for longest life. Since the engine is rated for 300,000 miles, this group of parts typically requires replacement several times over the lifespan of the engine.
since the parts are so dang cheap (compared to newer diesels) and fuel is so expensive.i see no need to worry about it.
you know how long it takes most of us to drive 100k? quite a while.
i do about 15k-20k per yr.
so even at 20k that's still only an idi tune up every 5 yrs.i'll be lucky to perform an idi tuneup two more times before my truck rots out sadly..........but i'll fight it til the end! (front fenders on their way! and getting paint job quotes now.
)
i know my 15+ yr old stock '93 E codes were nothing to brag about lol.changed those out,and instead of 5-6 second starts and lots of white,i have instant starts,no more stalling on descend,and very light white on cold start.
so these were bad @ 50k with plowing hours and age.

I don't put that many miles on my personal vehicles any more, but for years averaged 40,000 plus. This was the case when these pickups were new, and we generally changed the components when they caused trouble. I have had ip's give hard start symtoms, and I have had them just completely quit with no warning. I personally have never had one quit while running, but have changed a few that have.

My dually still has the original IP and injectors, it has about 350K kms, or somewhere over 200K miles on it, the other trucks I'm not sure about. One I believe is all original, it looks like the original return lines still. That one I just had the lift pump die in while it sat this summer, I may break down and change it tomorrow.

The engine I rebuilt for my truck had 75,000 on it, but it had been pulled and put in a barn by the PO. It had bad injectors and a FI pump that was locked-up. I don't know if that was the reason the PO had pulled it and switched to a gasser, but I thought it was stranger for them to be bad at that low of miles. The engine that was in my truck had 225,000 on the original FI pump and injectors. True, they were weak, but still functioning until the head gaskets went out.
On an additional note, I needed my pump rebuilt. I went to the local Stanadyne dealer. They initially quoted me 500 dollars to rebuild it. I told them I could get a rebuilt one from Pensacola for around 375, and they agreed to match the price. With the economy the way it is, I wanted my money to stay local to my community, and I like to be able to take it back to a local dealer in case of trouble, instead of the impersonality of the internet.

They said the extra oil (transmission fluid, motor oil, or a mix of some stuff I use) added enough extra lube to the diesel fuel to replace the lubrication that has been lost over the years due to new emission regulations, therefore, the internal parts were in good shape and within specs.
