There are lots of people that have no clue what it takes to keep 6.5 diesels together. Not to say that GM didn't have bad castings in the earlier ones, cracked blocks right up through the bulkheads just like Pontiac does when you overstress the blocks. The harmonic balancers have a habit of coming apart, and if you don't catch them they break the crankshafts soon after the balancer goes south.
They also had a propensity to crack cylinder heads from overheating, and blow headgaskets. ARP studs and good headgaskets usually solve that problem, but mine still have the factory bolts in the heads, one in the 95 is bubbling in the radiator so it probably has either a cracked head or a headgasket starting to go, I just acquired that one within the last 30 days, we'll see what happens with it.
The 93 runs just fine, has only had a waterpump changed out since I bought it in 2011, and I had to change out the injection pump when it took a dump.
They can be bought pretty cheap, and because they are mostly not heavy on electronics, you can fix them cheaply. Same engine that the military Hummers used until AM General quit making them.........
I guess I lucked out with my two so far...........LOL
