Right now i have an 06 LBZ Duramax and after reading about pistons cracking im thinking of buying a cummins because replaceing pistons is something im not looking into doing. Im just wanting to know what the best year for the common rail is to buy and any problems with those years. Whether its injectors cracking pistons head gaskets bottom end failuar cracking blocks like the old 53 block or anything you can think of id like to know. Also with that year any problems with the body like the front end. Thanks guys

 

My mechanic friend does a lot of ball joints on the 03+ front ends.

That's all I know about the trucks. I'm interested in this as well. In a few months I'm hoping to be able to buy me a decent newer rig and a Cummins is my second choice.

I would also like to know this. I'm about to sell my 1st gen and am looking at replacing it with a common rail. Hope someone chimes in!

 

04 is the best from the research I've seen best intercooler I've always heard 04 was the best

Everyone around heres been getting rid of there cummins for these 6.4s and 6.7 psd

 

04 has plastic end tanks on the intercooler......worst design ever.

If anything get an 06-0 5.9. Efi live is available. Injectors are about the only real issues. Good filtration will take care of them.

 

I appolagize 06 is the best 03-05 had plastic end caps

 

Other than the intercooler what are the differences in the 03-07? Such as mechanical differences. I've heard about the injector issue but almost every truck I've looked at buying has an upgraded filtration system.

 

I'd the 06-07.5 5.9 cummins is the way to go. The interior had a face lift as well as head lights, also the trans was flashed with tow haul as well as overdrive off that the prior models didn't have.

 

2004.5 325hp 600lbft available with nv5600 manual and metal cac tanks. Maybe some early 05's had the 5600 too. After that you get the 610 engine with injectors that have the ability to melt down pistons with little to no warning or at the very least fill your crankcase full of diesel. Also for the guys wanting a manual youre stuck with the g56 that is very common to fail. You can get efi live for the 06 up and the interior and front end is somewhat nicer looking and the 06 ups don't seem to be as vounerable to dropping valves/seats but, the 04.5 and some 05's are the way to go.

 

Thanks millerboyzdiesel, that answered a lot if my questions. Are there any major problems with the 03's? When I do get one its going to be 6 speed
