Still original at 190K.

 

154,000 and working fine. Power Service in the white bottle at least every other fill up.

 

I can offer the following from my fleet:
05 Excursion - two went at 145k, replaced all eight. Bought the truck at 109k. Truck had oil change history going back to new every 4-6k from the dealer.
06 F250 - one went at 109k, upgraded all eight to Holder's 205/30's coupled with a regulated return, a KC Stage 2R turbo, an ODawg's ported air intake, a FASS fuel system, among other things (it helps that we rep for all of these companies, lol). Bought the truck at 99k. Injectors had been original. Truck had oil change history going back to new every 4-6k with MobilOne.
06 E350 - one went at 130k, changed the one. Another went at 132k, changed the one. Didn't have service history outside of what was in the Oasis report.
04 F350 - still going strong at 185k on original injectors
06 F250 - one went at 242k, replaced all eight. Purchased at 235k. Don't have service history outside of what was in the Oasis report.
06 F350 - one went at 250k, replaced all eight. Injectors had been original.

No HFCM's have yet failed on any of these trucks. We recommend taking the HFCM off of the frame and taking it apart to clean it every 100,000 miles. Ford's gasket kit is quite reasonable and available from us as well.

We offer cleaned, flow-bench tested injectors with new seals beginning at $100 apiece. The top line OE-sized injector we carry comes with a 3 three year warranty and has everything new with the exception of the canister holding the fuel and even that is re-honed. It runs $225. Of course, every option in the middle and even larger injector options are available. We rep for the OEM, Full Force, Warren, Holders, Alliant/Pure Power, Dynomite Diesel, Bostech, International, a few others that I am forgetting and can compare and contrast the differences in what your money is buying. We won't be beaten on price, either.

When doing injectors, we ask people to consider using an injector bore brush, to consider replacing their dummy plugs and standpipes (as applicable), and to consider replacing their injector cup nipples and the associated orings (or at least use the injector cup nipple socket that forces the injector cup to be at 90° to the oil rail to minimize the chance of nicking the top injector oring during the reinstallation of the oil rail. We also recommend the removal of the FICM's relay during initial cranking while waiting to build the necessary 500psi of oil pressure to prevent any blips of inadequate supply-side voltage from hitting the FICM during this cranking. While we 'know a guy' that can rebuilt a dead FICM for pretty reasonable money, a headache avoided is always better.

5 of mine are original and have 220,000 on them. Stiction noticeable at 20 below so I just added some Archoil and we’ll see if it helps. 0 and above they start up fine.

 

Do you happen to recall at what mileage you replaced the other 3? Thanks!

 

Thanks for the info, and for the HFCM info, too!

 

Thanks WokfCreek540 and MrCrafty!

 

Rebuild them yourself (FULL) and you'll get 150K - 200K every day (min) -- once you master removing / replacing that top C Clip, it's a piece of cake. Keep an old head around on the bench as your "workbench" (holder) and you'll be able to knock a full set out in one hour.

 

It would also be interesting to know whether the injectors were operated with oil and/or fuel additives.

 

Mine has been operated with Lucas fuel additive it's whole life.

 

Previous owner replaced FICM, turbo and 2 injectors at around 60k he said. No idea why. I replaced 1 just because I was having head work done and there was a hole in the screen on one. There weren’t any signs of trouble with it except the visual which I don’t know what would have been the cause.

 

What screen on an injector???

 

There is a tiny screen n what I believe is the inlet to screen out any last particles that may have gotten through the filters or originated after the filters.

 

Cool. Learn something new. I just replaced an injector. Maybe I should have looked a little deeper. Thanks.

 

They have 3 screens around the perimeter that keep debris that may have made it past the secondary filter and it eventually gets returned to the fuel tank and hopefully caught by the filters. If you saw how tiny the injector nozzle ports are you’d see how they could get restricted easily.
