    Looking at purchasing a diesel k5 here in Arizona, and man! Not so easy to find really. I'll keep an eye out for the next coming months, but does anyone have any tips? I check craiglist.com, autotrader, and classifieds. Any sites/sources I am missing?

    Thanks

    tried auctions??

    I have only seen about 6 diesel K5's since I have been into GM trucks--only 3 or 4 of them for sale in the "Want ADvertiser" magazine..even diesel pickups are fairly rare here--not many of either were sold here with diesel engines evidently..and unfortunately the few that were are either highly prized by their owners,and they wont sell them,or want top dollar if they do!--and many of them that non diesel oriented people owned were junked after they failed to start on a cold winter morning more than once..or were beaten to death by a contractor or they towed horses and other heavy duty use..

    The biggest source of diesel powered K5's and pickups in the 73-87 year range was the US Military...here in my area we have GSA (Government Services Administration) auctions that sell off surplus military vehicles and equipment...thats the place to start looking first..(but I'd shy away from any 24 Volt models...they are a LOT different than the "civilian" models with a normal 12V system).....other than that,all I can say is keep looking on E-bay,all the "Want Ads" and dont forget to look behind barns,in feilds,andother hiding places where a "dead" or unused diesel might be hiding..

    Another route is to buy a nice gas powered K5 with motor or tranny problems,and swap in the diesel from a donor or junkyard truck...one friend of mine scored a nice 88 K5 with a 305 that had bad head gaskets or heads,and the guy ran it until it nearly seized up--bought it for 500 bucks!--and he found a school bus in a local boneyard with a 6.2 and a TH400 for 350 bucks!--now he has a sweet K5 with a recently rebuilt 6.2(bus had a reman engine 10,000 miles before it was scrapped after an accident!)...he loves it--gets 20+ mpg,and tows his boat like nothing!... :crazy:

    Ya

    I live in northern phoenix.. old horse raising area, so I guess i'll be farm crawling for a while, maybe I can get lucky somehow. Only way I'd buy a blazer with now a day's gas prices is if it was a diesel..

    Also I think the idea that i could always make it run B100 if I had to is a comforting thought with the whole oil deal now a days.

    Oh well, i'll keep looking for dead blazers/old 6.2l vehicles. How hard is the swap by the way? Besides the fuel system, anything wierd?

    not hard..

    Putting a diesel in place of a gas motor is a bit more work than installing another gas engine,but not too bad..

    Its best to get a tranny WITH the diesel motor--a gas tranny has a different stall speed in the torque converter--though it WILL bolt up and work!--some guys I know who used their original tranny from the gas V8's said they did not notice any difference at all!.--

    Other than that there is a minimum of things to change...the motor mounts are the same as any other chevy motor,you'll need the diesel radiator,mostly for its huge cooling capacity AND the fact it has a tranny and engine oil cooler built into it...you could get away with a big block gas radiator and external oil coolers instead if desired..

    The wiring other than glow plugs is the same as a gas motored truck,and a few things like the throttle cable and other minor things are different...its best to have a diesel equipped parts truck to do th swap,or at least know where there is a junkyard one to pirate the small parts off before attempting the swap--.

    tRusty K5 has done the gas to diesel swap in his K5--he can probably give you a lot more detailed breackdown of all the things you need to get and do if you go that route!..of course,the easiest way is to buy one that already IS a diesel,and fix all the bugs in it!..they ARE out there--they just seem harder to find than your usual rusty 305 powered K5... :crazy:

    Hard... more like time consuming(sp).

    When I got mine, I'd been looking for about three months. I finally had setteled on two. One was in Ogden, UT. The other was on Ebay in NJ. I went for the one in UT as I am in Denver and it was a tad closer.

    The best source is the classified adds of newspapers that post on the internet. You can pic how far you want to go to get one and just start looking.

    Good luck in your looking!

    Great advice everyone, thanks! IT should really help speed up my process, only thing that is sad now, is once I get it.. i'll only drive it for a week before I start lifting it and adding body armor.. *sigh* :D

    Oh wow

    I missed the two posts about the ones for sale.. that one in glendale on autotrader said it had a 5.7l diesel, which scares me a bit. Seems made up or something, and the one for sale does look mighty intresting.. now I gotta try and free up some funds. I wasn't expecting to buy in the next week or two, was just trying to find a decent source to look for them, as auto trader only had like 8 in the whole country. :) Thanks everyone.

    No 5.7 olds diesels came in the K5's. Most people know so little about these motors they just take a guess at what it is, and im willing to bet thats what they did there.

    dont buy a 5.7 diesel...

    :eek1: --The 5.7 old diesel might have never came factory in a K5,but many pickups did!--and anyone can swap one in!--but the only way I'd buy one with that motor would be :

    A: VERY CHEAP!
    B: Planned on installing new motor right away!

    That motor was a complete embarrassment to GM,and is responsible for the poor reputation of GM light truck diesel motors...unfortunately it carried over to the 6.2's--they aren't bulletproof either,but dont deserve to be confused with the 5.7 olds diesel,which was just a gas 350 made into a diesel.

    GM learned pretty quickly that the olds 350 gas motor,while a sturdy dependable engine,was not up to the task of handling the 22:1 compression ratio required to be a diesel!..they did not last long,in most cases all the trucks that had them had engine failure within a few years,and it was a nightmare for GM...

    I'm suprised to see a few are still running--I see a few trucks with the olds diesel for sale once in a while..but I've seen a LOT more in the junkyards than anywhere else!... :crazy:

    I got mine from e-bay under other vehicles, military. If it doesn't have to be pretty definetly look at www.govliquidation.com they have a lot of cool stuff there. Mine is a cucv (government issue) and I got it with only 40,000 mi. So far I really like the 24v system because it starts like a charm and especially in the winter the batteries have a lot of power to cycle the glow plugs and still have power to turn over the engine.

    Took these sometime ago here in town at the Army National Guard base. Pretty bad pics but I think you get the idea. There were 5 rows of atleast 15-20 in each row.
