I think 01 and 02 7.3l have a special coating on cylinders that drags down power so if your going for a powestroke 99 and 2000 are best.

 

What a joke.. do you know what you are talking about???
I dont think so..

to all the cummins guys do you all get 23-24 miles per gallen all the time on the hwy??
and 16-17 towing 17,000-25,000????

 

In 2002 they put a coating on the pistons. Its no joke...

 

You could avoid these problems by picking up a Duramax with an Allison, no engine or trans troubles unless you tune it to high hell and beat on on. Front end on the GM's are notoriously weak, nothing that cant be fixed with some elbow grease and a $1000......I think im about to anger the Ford guys

08 GMC LMM, DPF Delete, Cat Delete, EGR Blocked, PCV Reroute, PPE Stage V trans, Edge...etc

 

I really like my 2010

 

I have friends with the Dmax.. From what they tell me and from what i see.. I would Never buy a chevy with a Dmax in it.. When comes down to it they are not much more reliable then the 6.0L Powerstroke.. In fact a lot of 6.0L have less trouble then the 6.6L Dmax..
They seem to have lots of injector problems and wireing problems..Just to name a couple..

 

Must have friends with bad luck, I've beat my lmm(2007.5-2010) on desert trails, the highway and through the mountains over the last 87,000 miles. Never heard of injectors going on the lmm's, unless you start running used motor oil as a mix with your fuel (yes we all know that genius....) Biggest problem I've had with mine is the fuel gauge reading lower than it was. New set of tie rods and the Dmax is good to go.

 

Bad luck?? I dont think so!! I know 4 Guys that have had injector problems with the Dmax any where from 2001 years to 2006 or 2007 years. they all have had to have the injectors replaced in and out of warrenty.. one Guy is on his 3 set of injectors with only 120,000 miles on it it!!! To me that is not just a out of the norm.

 

Ya, I'm going to call bs on that one too.. My boss went through a couple motors and tranny's before he finally got a solid set up.

Saying Dmax is the answer to all the problems is crap... Every truck has its issues that need attention...

 

Incorrect. The pistons in a 96 7.3 are the very same pistons in a 2003 7.3... no differance what so ever.

Now they did change to Powdered Metal Rods in 2001, which are "slightly" weaker then the earlier Forged rods, but unless your looking to go over 400hp its not an issue.
