I'm looking into a Dodge or a Chevy. i hear about people changinh out chevy injectors all the time. Would i ever have to change out injectors on a cummins?
 
Yes... Over Pressurize or bad fuel ,otherwise 300k is high 200K is average. I have seen and heard 400k,but thats the exception not the norm.
 
On the Common Rails the Electronic Injectors can stick open anytime.

Some TDR Writer's say change them at 100,000. Their is also new Stainlless steel injector bodies out there now that hold up better.
 
If you keep it stock and use good filters you will most likely will get lots of good miles out of your truck == Good luck

The injectors and fuel system between the 2 trucks is almost the same, they can both have issues.



Better and more filtration on either one is going to improve the failure rates. With the Dmax you will need to add a lift pump to get better power and use more filters, the Dodge can push thru a 2 micron and still supply the needed fuel if you keep it stock.
 
Most of the d-max injector issues are on the LB7 series engine. This engine series (LB7)is no longer a current production engine. The newer D-max... LLY and LBZ have much improved fuel systems over the LB7, and are getting almost as reliable as the Cummins... Well, until the 2010 emissions changes... I guess we will see how durable their 2011 engine is.
 
I have coffee with a gent who's had 2 sets of injectors in his Chev and he got rid of it before it was out of warranty as he didn't want that expense.....

I've owned several fords which all had injector problems... . as well as wiring problems in the valve covers.....

I know currently own 4 of these trucks... 04, 04. 5, 05, 08 all of them have over 100K and the 04 is close to 300K... . mine are all stock. . we've not had a problem...

All we did when the trucks were new was install a 10 micron primary, and a 2 micron secondary filter on the frame rail. . We've done the same to a couple of CAT engines we own as well.....

We don't get fuel in stations but only commercial card locks where we can see a filter on the pump...
 
Yesterday Customer shows up with needed service, I should have taken a picture of all the steel debris on My magnet taken form stock filter housing (Bottom). Needless to say he going to put the truck up for sale. If you keep the fuel uncontaminated you should reach 200k before replacing in most cases.
 
Replaced one injector at 98K or thereabouts. It was under the extended warranty. You'll know what the problem is if it's hard to start but runs fine otherwise.
 
I sold a 2001 Duramax LB7 after 3 years and 65,000 miles. The injector issues were so common I figured I was buying time. I did not want it past warranty. I sold it in 2004 and have had my current Dodge since. This is the longest I have ever owned a new vehicle. Six years and running. 95,000 miles. To be honest with you I have been driving diesel pickups since 1993 and have never had an injector fail. I do use Primrose 405 diesel fuel additive in this truck and also the Dmax. I don't know if it's a contributor to the good life but I'm not gonna stop using it that's for sure.
 
I would suggest that you not run crude oil as fuel in your truck as many folks around here do. I don't and have not heard of any negative affects, but there is just too much risk for the savings. One of our contractors burns straight Pennsylvania Crude Oil in his JD backhoe and trackhoe in the summertime with no problems. Not sure if he has additional filters or not.
