Don't worry about replacing your injectors until they go bad. I just replaced mine at 207K miles, and that was just because they were needing new o-rings, so I went ahead and put in reman single shots instead of having to go thru and have them cleaned and tested and find out a few might be weak or bad.

BS! I have 177,XXX on mine and they are still going strong. Run a good additive in your tank like FPPF, XPD, or 2% Bio and you will get them to last you a long time. I prefer FPPF because of its water dispersing qualities, the others are ezually as good.
Here is a nice little link to inform you which additive actually works.

the reason why i asked is because i picked up a very noticable ticking sound at idle, my PSD has 113k on the clock and was wondering if one of my injectors was making the noise.

Sorry to butt in, I got a noticeable ticking noise at idle too! Just started not to long ago. don't remember hearing it sound like that before. I got 100,000 miles do for an oil change soon. I was wondering the same thing, what could cause this..

What is the difference here in the injectors? What is an "AB" and what is an "LL"?
STILL learning. Nice pic. I have never had the valve covers off. And won't till I have to.
Thanks,
Donnie

These engines have injectors named by IH with either an A code or a B code as the first letter. Here's a sticky off of PSN.-
An AE injector actually displaces a wee bit more fuel, due to the fact that it's in position 8, and cylinder 6 fires directly before 8, which puts a pressure drop in the fuel and oil rail pressure, so the injector actually is dificient, thus needing to inject more fuel to keep its load. Once you do a regulated return system the need for this injector goes away, and then you can replace it with a regular A code.
A and AA injectors came in the '94-'97 non-california trucks. They are all 90cc injectors and are single shots.
AB injectors came in the '97 cali, and all early '99 trucks. They are split shot injectors meaning they fire a small pilot shot before the main shot. These injectors flow 130-135cc of fuel.
AC injectors are found in the high torque version of the T444E and do not come in any Powerstrokes. They have the same internals as the AB injectors with the exception of the single shot plunger and barrel. However due to them being single shot injectors they flow 160cc. This is due to the way the split shots work. They have a small passage that opens, much like a port in a two stroke engine, that are uncovered that bypass the injection pressure out the side of the barrel instead of out the end through the nozzle. Because of this pause a portion of the travel of the plunger does nothing for injecting fuel so a split shot injects less fuel for the same amount of travel as a single shot.
AD injectors are also split shot but flow 135-140cc of fuel due to a slightly longer plunger stroke. These are found in all late '99-'03 Powerstrokes and T444Es.
AE and AF injectors are essentially the same as AD injectors but were called a long lead injector that was used as an attempt to cure a "cackle" issue many people complained about.
BA, BB, and BC injectors are essentiall all the same and are the same as AC injectors but are found in some DT466s.
BD injectors are the only B codes with the larger 7.1mm plunger and barrel that are single shot injectors. These are the injectors people are usually talking about when they are talking about putting I530E injectors in their Powerstrokes.
BE injectors are essentially the same as the AD injectors but found in some '97-'99 DT466s.
EF, BG, BI, BJ, BN and BP injectors all have basicly the same capacity and are split shots. However the nozzles vary on them depending on application. They can be found in many DT466s and I530Es.
