diesel rebuild?

i was wondering if anyone knows what is involved with rebuilding a diesel, or if it is worth it. i bought an 85 k20 with a 6.2 in it. i bought it for the axles, but then got to thinking i may want the engine out of it. im not sure of the condition, and it doesnt have a starter. so now the question becomes, is it worth putting the money into it to replace my tired 305? or should i just look for a 350? thanks for any help.

Re: diesel rebuild?

No. The 6.2L is the most abhored diesel around. They got better down the line but yours would be one of the first ones. They cost more than they're worth to rebuild and once they start needing diesel-specific replacement parts you could have had two rebuilt 350s.

If it was in good condition then it'd be worth fixing up. But the effor involved in sticking a diesel into a gas engine compartment definitely isn't worth it.

I'd put the money in the 305 before I put it in to a diesel that you'd swap.

Re: diesel rebuild?

The 6.2's and 6.5's are touchy motors, some years are okay, but others are junk. Unless you have a lot of money to spend I would stick with a small block. It wouldn't cost too much to swap either, unless you were going to go EFI. If you want a stump puller and have some moolah, check out peninsular diesel. They have some kick as$ diesel motors and upgrades. The early 6.5 TD's didn't have the computer controls like the later models did.

Re: diesel rebuild?

Well, if you maintain your motor then it isn't so bad. But call up some place and ask them how much new rings and bearings are for it and you'll see what I'm talking about.

I think I'd buy a Goodwrench 350 before I bought a diesel. Of course, if you're bent on sticking with a "Number 2 fuel" burner then I guess you're stuck between a rock and a hard place.

Re: diesel rebuild?

The 6.2's are good engines. Not huge power makers like a gas engine, but they deliver good torque down low (good for wheeling and pulling) and give you near 20mpg for daily driving. Before you dismiss it, talk to the guys over at some of the GM Diesel specific sites and the guys over at <a target="_blank" href=http://www.ColoradoK5.com>www.ColoradoK5.com</a>. They can be made to make some good power and torque, but it isn't a cheap thing. Still, the guys with the full on Banks turbo charger kits have 350 fuelie hp, Big Block torque, and get 20-24mpg. Not to mention diesel is usually cheaper than regular anyways.

When I get my K5 I'm going either 500 Caddy or turbo charged 6.2L diesel.

Re: diesel rebuild?

yeah, i got to thinking last night, my 6.2 in my 86 chevy isnt smoking near as bad as the one in the GMC, so i will prolly just swaping the one for the other, ill prolly never get a transmission for that Scottsdale anyway. or ill get a crate 6.2, i do a good amount of towing, and they do get good mileage, i drove my chevy the last year and i got better mileage then my S-10 is now. and 87 octane is 1.38 here, deisel is 1.28
