Uls Fuel / Premature Injector Wear Concider This A Warning!

[Gus's 03]

so, i know the big oil companys said they did tests and removig the sulfer didnt cause any accelerated wear..... i call bs!







ive been seeing ALOT more nozels/injectors coming in that are fubar.







I HIGHLY RECOMEND USEING A FUEL LUBE ADDITIVE!











You'll note that in the folowing pics the seat area where the neadle seats is pounded out, and has actualy moved down int the spray hole area. . i have seen nozels come thru where the neadle is recessed . 035" !!!







pardon the camera phone pic quality, but i think this is definetly where a pic is worth 1000 words!

So do you think that if I keep running the Stanadyne PF it will help my injectors last?

 

[2broke2smoke]

good post ...



were they on a stock truck?

 

[Gus's 03]

some stock, some modded, ive seen ALOT of them seeing it on mostly cr trucks, but seen some on vp's etc

Fuel additive did not prevent my injector from failing... I ran it every tank.

A little correlation between hours\miles and the failures may tell a different story. You simply could be seeing more failures due to the age and mileage rather than any fuel related issues.



Pretty large jump to blame the fuel only with no other info or data to back it up.

Another consideration, with high fuel prices more and more "other" fuels are likely ending up in the fuel tank and contributing to the situation.

what failed? theres alot of things that comonly go wrong that lube wouldnt have any thing to do with

lol... . trust me . . . its been hundreds over about the last year, not just a handfull..... we have looked verry hard at it for a while before making any sort of post. and some have been less than 50k miles on stock trucks.



take it how you want... ... but im just posting it up because theres only a few shops in the country with the rescoures we have and feel the wear is avoidable.

OUCH... ... I like to add a couple of gallons of B100 (from a certified source) to a tankful... . It probably winds up at about 1%, but more lube than the previous "low sulfur" (500ppm) fuel.



Now we get ULSD at 15ppm, and the bureaucrats figure that there won't be any difference in the lube factor??



MAN... I'd like to rule the world for just one week. I'd straighten things out in a big hurry... .



By the way... I know there were quite a few VP44s taking a crap with the 500ppm fuel, but did anyone notice the really large number of failures that coincided with the introduction of 15ppm ULSD?? Three friends and three 98. 5 CTDs at work all took a crap in the same month.



4psi AND 15ppm were just too much for some pumps... .

It's the nature of the beast. High pressure is pounding unwelcome intruders into the injectors like never before. A 2-micron fuel filter after the stock filter may be the best medicine available. Of course, a little extra lube from 'something' could'nt hurt. Just my . 02.

 

[steved]

The seats were beat to death... all six were in very bad shape.



I also never idled my truck more than a few minutes... and had 1 micron filtration for over half those miles... and ran additive in EVERY tank.



I don't think there is a correlation between injector failure an a SINGLE cause... I believe there are many cases for injector failure, and fuel is only one of them. The injectors being a POS is the main issue.

So hundreds of injectors from where? Locally? Regionally? Nationally?



What are the usage scenarios on these broken parts? High idle times? Grocery getters? Haulers?



How many had contaminated fuel? How many did not get regular maintenance? How many with additives used and not used?



How about the many trucks with 100k, 200k, 300k etc, with no injector issues? I know, I have one and can find 10 more people the same or higher mileage that have/had no issues.



How many things like this thru the years that have come out "If you don't do this..... " or "Save $$$ by... ... ", etc, etc, etc? Pardon my sketicism but the gal trying to sell me 2 mason jars that supposedly create a flammable gas to stuck under the hood of $40k truck really tends to jade the senses. :-laf



Do I believe the crap we have for fuel contributes? Yessir, you betcha!!



Do I think anyone can point at the fuel and say definitvely, yes its the problem? Convince me with some hard data and you got my attention.

I'm down to half a quart of 30w nondetergent oil per fillup. Whenever I forget to use it, I hear louder clatter. It seems like half quart is the smallest amount that makes a difference, and it won't smoke, and costs only pennies. I occasionally run MMO or PowerService.

 

[DPKetchum]

New injectors are said to be a updated part number with a hardened ball and seat. May also just be a design issue. Thats would be my bet on the issue. Poor design.

I don't have the technical background as some of you, but I have to agree with the above statement. My injector problems with my '04. 5 were all early in the trucks life (like at 10,000 miles), well before ULSD came along. From anything I have seen over the years there were many more injector problems with the early CTD 600's ('04. 5 - '05) than what has been seen in more recent models, and these were before ULSD hit the pumps. I think it is far too speculative to blame the injector issues on a single cause (other than perhaps design flaw), just as Steve (I believe) said in a separate post.



I haven't had a single injector problem the last 3 years, much of which using ULSD.

I was told excess noise does not necessarily mean excess wear.

I tend to agree... when was the part updated? I was thinking it was an early 04 update??

 

[DPKetchum]

What I read is if they were used in production at all it was at the end of the 07 model run(5. 9) if used at all other then replacements. Whom ever is one of the big gurus on rebuilding and turning out performance injectors I think is where the new part number,hardened ball/seat info came from. Not sure which forum I read such info. Probably need to inquire with Bosch or Cummins

Along with quality control problems on the manufacturing end, that is the most probable cause. Bosch engineered them to the specs that were provided when the systems were sourced and I don't believe they had anywhere near enough data on the fuel and conditions the trucks get used in here in the USA. Like anything else, real world usage over a period of time generally sorts out the design flaws, material and maufacturing issues.
