My buddy is looking at a nice '85 3/4 ton suburban. It has a good running and sounding 6.2 Diesel. Are these decent engines? I have heard they are tough and long lasting, just shy on the "power" side of things. Thanks
I also heard of a crank shaft breaking problem, but I believe that was on the 6.5, not the 6.2
The 6.2L GM V8 diesel came before the 6.5L. They are horrible motors in my opinion, and I have had the displeasure of using quite a few of them in HMMV's. This is the craptastic reworked gas big block that GM turned into a diesel. They suck, have no power, and inf used to any degree of hard work tend to break.

I thought the 6.2 was a detroit diesel spin off?
I have always heard (no personal experience with the 6.2) that apart from being slow... they were alright.
My dad installed a 6.5 turbo in his Nissan Patrol Cab Chassis - apart from 2 injection pumps, was a good motor.
I own a couple of those..They made a lot of noise.. There were dependable but the motor was the only thing dependable on those..Tranys did not hold up at all...

To the O.P.: Run away. Far far away.
Why are you still sitting here reading this. RUN
Wrong, wrong, wrong.
The only part right is that the 6.2 was in the HMMWV, which bye the way is really, really heavy and not built for speed at all.
The 6.2 was a detroit diesel and like another person posted, did what it was supposed to. Last forever, move things, be reliable, and run on diesel. They were a little slow, but that's because they were naturally asperated. If you put a Banks turbo system on the 6.2, it makes more power than the stock 6.5 that replaced it.
Oh the the 5.7 was totally built as a diesel engine. The problems it had are very similar to the problems of the 6.0. Not enough head bolts, using torque to yield head bolts, rushing to production, not having adequately trained mechanics and a problem that it doesn't share with the 6.0 is the lack of a water separator.
Supposedly after these things were worked out the 5.7 was a decent engine, but the damage was already done.

A friend of mine has one and it is constantly broke down. He has been trying to sell it without luck and it is in a very nice truck ton dually. He has several much rougher trucks in his business but they are dependable.

6.2's are decent motors but as everyone said they are low on power. With the price of diesel though I'd like to have my 83 6.2 back since it got 20mpg in town. Mine ran awsome for 250k miles, got rid of the truck about 5 years ago.... I had more probs with the OD transmission than the engine!
A good friend of mine had a 6.2 in a 3/4 ton Chevy in high school and it was a GOOD ENGINE. It made ample power (I thought) and got WAY better mileage than I did w/ my Ford I6. However on the flip side I have a cousin who put 3 different 6.2's in a 1 ton Chevy in a matter of 8 or 9 years. So its a toss up I guess, the big factor would be if they know where the vehicle has been and how well it has been treated.

A well treated 6.2L will last forever. I worked for a lady who owns a Suburban with a 6.2L in it and it's nearing 400,000 problem-free miles. Just now acquired a minor fuel leak but an easy fix from what I can see. It's ugly and noisy but it will get from A to B.
