Tell me what you know about the ol' Duramax's

[DamnYankee]

I'm undecided whether I'm getting a Duramax or an HD2500 with a 6.0l.

Any info you guys have about pros and cons would be greatly appreciated.

I've been told some of the Duramax's hd some years with bad injectors...possibly some other problems...?

I think it comes down to towing whether to get the gasser or the diesel. If your not going to be doign that much then just get the 6.0

[DamnYankee]

Don't diesels typically outlast gas engines? That's kind of why I was considering them.

Think its the 01' and unders that had injector issues but if you find one of that year model, the problems most likely have been fixed by the owners... or should have been anyway. I'm in the market for one myself and haven't resorted to selling my baby yet

I am planning on buying one. You want an 06 with an lbz motor. Strongest and best made duramax. The new ones are LMMs but they have a diesel particulate filter that restricts them somewhat.
Talk to Mic and 01slowz71/ Cody. I think midnightrider just got one also. The 06 also has the 6 speed allison trans. I drove an 06 the other day and would have it but it was red. The lbz engine has a higher red line also.

You will still have an ls engine in the TBSS so you are still good to go.

A lot of you guys dont know cold. As good as the Durtymaxs are in the cold (for a diseasel) still not as a reliable as a gasser for those real cold mornings, plugged in or not. Moze I cant really see you needing one, unless you plan on massive trailers. They're a hell of a lot more expensive in every way too. I dunno the only experience I have with them is all the failures that come through work. At least 2:1 over the 6.0s. So I am kinda biased. Hell that one behind my truck in my sig pic not even touching 150000 miles yet, and it's in for a complete top end. Plus you dont seem like one of those tools that buy one just to have a diseasel, because there the hot ticket right now.

Expensive as heck to work on too.

[DamnYankee]

Well that helps answer my question...I'll stick with a 6.0l. Thanks guys.

stick with what you know and are comfortable working on. dmax's are great if your towing something, but if not, just a waste of money

p.s. if you want lots of towing power, cummins is where it's at.

'01 was the first year of the Duramax dufus.

The LB7, which was the first DirtyMax (01-04) are known over the other variants to have injector issues. And the labor costs are high cause you have to remove the heads to switch out the injectors. There were also complaints of overheating issues. BUT I have heard of the other ones having the issues as well. The injectors come with a 100,000 mile warranty.

The LLY was the next one...some 04s had them--but continued into 06. They had the revised head design which allowed for the injectors to be replaced without removing the heads. The LLY is definitely better than the LB7.

The LBZ (early 06-07 Classic) was the one matched up to the 6 speed Allison. The LBZ was the best Duramax of the NBS trucks. This is the one to get if possible, but the LLY is good as well.

The LMM is in the NNBS trucks, and is pretty much the same as the LLY, but it has the DPF choking it back.

Moze, diesels are great, don't get me wrong. They are for an intended purpose, and require good routine maintenance. They are also a little more expensive to run, but they make better power and have better mpgs than their gas counterparts.

Good point. The 6.0L will be more than enough for what you wanna do, as a typical DD. But you know what a tune and minor bolt ons can do to the performance and mpgs!

p.s. if you want lots of towing power, cummins is where it's at.

If you want a diesel, get a Cummins. Conversation over.
