Engine/Transmission (1998.5 - 2002) local shop Installed wrong injectors?

[Grizly]

Looking for advise on what damage could have been caused by ADS certified shop installing wrong Injectors in my truck: truck never been done nothing to it til I had them install was to be 100 HP injectors / Now after much other stuff done to compesate for the black smoke and drive for 24000 mile with them in I then decided to change to lower hp injectors Jammer 2 80hp well here is where it gets bad the injectors that was installed prior was 12 valve 300 - 330 hp tips on 24valve body: smoke is gone and even seems like more power sounds different at motor but How much damage to the pistons?/? smoke now coming from blow by tube and my oil used to stay clean for at min 1000 mile before now I never see clean oil maybe that will clear up but what thoughts you guys have on this... should I persue to get 1st local shop to pay for damage or worry none about this??/ O and most of driving is done with Trailor on back say 85% of time...

I believe that the 12v injectors have a different spray pattern as the piston bowl is different. It may have caused damage to the pistons, did the tech scope the injector hole to check out the piston crown for damage?

 

[Grizly]

No they did not, they was done with truck and I wanted to Know what the tips were since I was keeping them and they then found out by part # what Injectors was: Now I am here looking for advise of what to do with... Yes that will be on my list for them to do that you stated :scope the injector hole to check out the piston crown for damage? Thanks

i don't even think a 12 nozzle can fit on a 24v core, they are totally different.

I've seen some of the Cummins locations with a scope that will fit into the bore of the injector and will display on a Computer a digital image... the bore scope is a camera... . its very flexible and looks like a flex sig (sp) that a doc would use to look into your stomach or run into your heart for a look at a valve... .



One way or another I personally wouldn't drive it much until I had it looked at... . if you can't find this quality of scope in your home town I'd ask them to pay for at least one head to be pulled and visual made of the top of the pistons... .



One thought here. . way too much fuel might not cause a problem because it floods the combustion chamber... . however too much fuel can wash the rings off and than excessive wear sets in... . and you burn oil... and it sounds like this has happened... .



Good luck... . keep us posted... .

our trucks only have one head. but I too am curious as to what you find out.

Well, thanks guys still looking for some one local that has scope to do this thinking might have to pull head and look... strange thing is I did not have much steam or what ever coming out of blow tube before putting corect 24 valve tips on: This is tips that was installed 330 hp injectors :Germany Part # DSLA 155 P 276 / 77017 / (060) some one please check this and maybe I am wrong. .

 

[JCyrbok]

If I read ur post correctly, you have driven 24,000 miles on the suspect injectors?



I am no diesel mechanic but would think that if there was major damage that it would have reared its ugly head over the last 24k miles. But for piece of mind I would still have it checked out further.



just my 2 cents

major exhaust black smoke , I would only have to let clutch pedal out no throttle and black smoke was at rear of truck and lack of power expected. .

Thats kind of what I was thinking, I've sat both side by side and they are distinctly different. However I did not try to install them on the opposite bodies to see if they would work. If your spray angle doesn't match the piston bowl as I'm pretty sure it wouldn't That would make sense for some of the black smoke and relatively low power. It is my understanding that the fuel that combusts in the bowl is going to give you most of your power, correct me if I'm wrong though.



I would highly recommend getting it looked at like all the others have suggested. What kind of EGT's were you registering?

If EGT's were monitored and in check I highly doubt there was any damage done. Perhaps some accelerated ring wear if in fact it was washing down the cylinder that bad. I have run injectors so big the truck blows white smoke at idle and not seen this though. If you are not getting excessive blow by out of the vent tube, i would run it and be done. I dont think an incorrect spray pattern could damage a piston, unless due to excessive egt's, but i could be wrong. The original shop is most likely going to tell you to take a long walk off a short pier anyway. I would put it out of your mind and run it.

My similar experience. In early 02 I was looking to gain a few HP for towing. My local guy went looking for genuine Cummins, and found a set of what were purported to be "275 specials" from a Cummins dealer. After install, I smoked every speed above idle. Power seemd the same to me. At 1400 miles after install, #6 developed a hole right at the lip of the bowl on the left side. The other 5 were obviously corroded in the same general area. The culprit turned out to be the wrong tips on a set of RV275's. We were told that 275's were very scarce at the time, and these were sourced from a supplier in Germany. The dealer paid for my repairs, and new ceramic coated pistons. I had to pay 1/2 the labor. If this were mine, I would have it scoped ASAP. If you find damage later, there is no way to relate it to the previous injector.

 

[Grizly]

I monitored egt very well and was getting high quick but never let get over 1250 for too long mostly ran at 900 - 1000 on hwy @ 70 mph , I was thinking too much comming from blow by tube but had noticed new shop install forgot to hook up main vac line which for some reason helped blow by tube after hooked up again? each day goes by seems it runs better I am thinking its o. k. but I asked shop how much to change pistons out if damaged and they stated around $5,000. 00 cause of pulling motor to do & lots of time spent labor = down time which would only cost me more $$$ as I use my truck for Work. . Can't find any one with bore scope in north west Alabama to help me with this...

Whereabouts you at Grizly? I'm just east of B'ham and would like to know what shop did it. You can try Diesel Unlimited in Pelham/Alabaster, but Id take the trip to Atlanta and let Garmon look at it if it were me.

 

[Grizly]

City Diesel is who put new injectors in and Found part # for 12 valve tips that was put in at Tuscumbia, Al. shop / City Diesel stated they did not have scope to look at pistons and did not know who does have??
