I have a 2005 cummins with 135,000. I have an edge hot juice which I run on 3 , a bully dog crazy Larry downloaded which I run on 3 and an industrial injection 62/12 turbo. I lost my #1 injector a month ago now I just lost another one. Is this due to my module and downloaded or normal wear and tear. I called scheid diesel today and they said a normal common rail injector is good for 100,000 to 125,000 miles. Any advice

 

It sounds like normal injector wear and tear.

 

If you are not running extra filtration then it is normal.

Average lifetime should be around 200-225k with good fuel and good filtration. Lacking that there is no telling when they will go bad and the programmers won't help the life expectancy.

 

03-04 can last a lot longer as they have about a 25% lower duty cycle since they do not have the post injection event.

05-07 we see problems typically between 80-120k , but occasionally will see higher 160k or so. 03-04 we see 160-220k and sometimes higher.

FYI we will test injectors for $10 each.

Starting with a quality injector is key... then protect it with good fuel and good filtration. Pressure boxes will cause greater wear.

 

Thank you Jkidd. I brought to a shop by me. They recommended I replace the other 5 injectors, put a better fuel filter in my canister and they ordered a after market fuel filter to add when it comes in. I guess 130,000 isn't so bad but its a big expense.

 

I just hit 133,000 and had to do mine, I replaced the #4 at 107,000. I just replaced all 6 2 weeks ago and went with +100s.
