Detroit diesel education please

[TexasR.N.]

Howdy all,
Might have found a great deal on a 1984 Army diesel blazer. It has a 6.2L detroit diesel in it but is currently not running. I was told that it needs an injection pump, and that Ford makes one that fits the engine. The part is a DB-II or something along those lines.

Any thoughts on detroit diesels?

Ya, a DB2. should be able to get a pump for around $450, replace the injectors too.

Pretty pokey as far as power, if you turn it up, you'll blow the crank right out the block, lol. they get decent mileage. run pretty good, start like crap in cold, bout like a 6.0, lol. I never seen one that went much more than 100k miles, no turbo stinks, would help power, but it'll break.

Are they expensive to rebuld after 100K miles? Injectors show to run about 50.00.
Thanks for the reply.

I had a 6.2 1500 Suburban and it was a dog but man I got some great gas milage out of that thing. Rebuild when I looked at them wasnt to bad compairable to building a big block. There are turbo kits and updated part to add to help with the power. You can even use some of the 6.5 diesel parts on it as well. look at the 8th digit of the vin cause if it is J it is the Higher HP I think C was the other code.

yeah they were turds by today's standards,but I always wanted one of those blazers with the 6.2 to make into a woods truck.I used to work on the BIG diesels years ago and the 6.2 was kinda the butt of every small diesel joke, everyone referred to them as a boat anchor because that's all they were good for.
But to this day if I came across one of those blazers and had the extra money I would buy it.

Everything from back then was a "turd" by today's standards. I had an '85 GMC full size Jimmy (precursor to Yukon) with the 6.2. I went through one (or two) injector pumps and the front end was a little loose, but that truck hauled firewood; plowed snow, and pulled trailers up to about 4k lbs It did everything but race and it was a great engine. I only got rid of it for my (current) 1995 Yukon 6.5TD because the body was rotting off of it. It had over 175,000 miles on it and showed no signs of giving up. In fact, the dealer that took it in trade used it as their plow truck for several years. Nothing wrong with the 6.2 as far as I am concerned. People talk about breaking crankshafts etc, but since I don't tune or abuse vehicles (I just work them hard), I never experienced that kind of problem. That truck made me the fan of diesels I am today. I just hope this new Ford doesn't change my mind!
