They are junk first, and underpowered 2nd, 3rd, and 4th. Better keep a lift pump and an injection pump in the toolbox at all times. Never tailgate one, you never knoiw when they are going to quit on you.
They are a very reliable engine/trany combo for light duty towing. They did have issues with inj pumps, but they have been fixed.
These engines run very well and for a long time.

We had a heavy equipment mechanic from a huge Cat dealership transfer over to our shop and when I found out he owned one I kidded him about it a time or two knowing about their unreliability. He said he'd never had any major engine trouble. Some months later on the way home I saw his truck pulled over on the highway and his #13 boot soles sticking out from under it. Truth be told, he finally admitted as I gave him a ride home, his engine had just grenaded for the 2nd time. 3rd time was on a trip across the nation, thankfully the cops said he could leave it overnite on the road shoulder, a drunk totalled it during the nite, he came back from vacation with a new Dodge diesel and lived happily ever after.

ha the 6.5 is pure scrap...My boss had one and the crank went out ...we were were at a stop light and he got on it...all the sudden the motor sounded like tow skeletons ****ing on a tin roof....I would stay away from them. but if you get a good one you cold get alot of miles out of the.
***Aren't the 6.5's still used in the Hummers the military uses?***
as far as I know they use the duramax...I know civilian hummers have the duramax.

330k miles and a straigh exhaust. Sold and missed dearly.
the 6.5 liter diesel engine is garbage. but there are a few companies that offer upgraded parts to solve the known problems. the only way to get an allison-duramax package in an h-1 is if u get the alpha dog upgrade and it is freaking expecive. FYI i spent 3 years at a chevy dealer working on nothing but 6.5 and 6.2 liter diesels so i do know i big of a peice they are but i have seen a few with the upgraded fixs on them and the werent to bad.

I owned a 93 6.5 crewcab - bought it off the lot - it was the first year of the truck, and I was excited because of the 6.2's reliability reputation. My truck ran for 80 K troublefree miles, and I wrecked it twice! Sold the truck to a mason who STILL owns it today, like 300K miles with incidentals like injectors and such - although he can't keep the front left tire in good shape for long ( refer to : wrecked)
Now I have an 83 GMC 3500 crew 4X4 dually with 4" of suspension lift and a 6.2 diesel in it. I also have acquired a good turbo from a 6.5 and the manifolds. I just need to know how to hook up the oil lines, but I am having a hard time finding pics or diagrams of how the original motor was plumbed. ANYONE?
PS - I now am the proud owner of a 2005 E-350 ford van with a 6.0 diesel which won't run for more than a week in a row. I have paid it off ($35k) AND have poured money into it ( $15K more) , only to continue having problems with it.
I hear the new 6.4 diesel ford is getting like 8 MPG - way to go FORD - hurry up and get it out there - forget the testing, just have the most HP. ( BY the way, did ford fix the flame-shooting-out-of-the-exhaust-pipe problem???)
05' E-350 Ext. van w/ 6.0 diesel.

Hey guys I'm looking at buying a 94 with the 6.5 that's been really well taken care of and I was wanting to do some reading up before I cut the deal. All of your input is great. What I really wanted to know is how much is a rebuild on one and are there crate motors out there for them. Just as in an oh sh*t case. I doubt that this one needs any work truthfully
Just bought a 97 Ext cab 3500 3.5L turbo diesel other than the rust at the corner ext cab and some dings and scratches it all seems well. Done a carfax on it and its been serviced and it all looks good drives good. Better for towing power rather than speed I think. I just bought it for local use not over the road. I going to keep fixing it up and sell it later down the road.
