Just got the engine all finished up, replaced that cracked supply line with the one that Brian (Wrench) was kind enough to offer me.

Bled it all out, filled it with coolant, started right up. Drove it up to the front of the house to top the rad off with a gallon or so of water, and noticed a major fuel leak off the side of the injection pump where the throttle shaft runs through the IP. Also spot two coolant leaks, one off one of the rear crossover plates, and one off the upper rad hose thermostat side.

Figure I'll park the truck inside now that the engine is in and running, so I can fix up those leaks and replace the front differential. Leave it idling just outside the shop while I run inside to move the other truck out of the shop so I can put the 86 in. During the time that it took me to start the other truck and pull it out of the shop the 86 had stopped running. Figured that was weird, cause it was high idling smoothly with a very healthy rattle, but thought it might have come off high idle and stalled out due to the screw being set too low or something.

Hop in to start it up, and the truck cranks very slowly while making a squeaking sound :doah::doah::doah::doah: Starts back up, but immediately dies. Try again, and the engine won't even turn over. I tried turning it over by hand, and I can't move the crank :mad: Seized solid.

So, the $1000 bucks I just dropped on buying the engine and replacing the timing chain, putting a main girdle in, new glow plugs, injectors and other crap for the thing was totally thrown down the toilet. Not to mention 3 weeks of labour outside in - friggin' 40 weather for absolutely nothing.

I am NOT happy.
 
wow man. Im sorry. That flat out sucks. I have been in the same type of situation before and it is not cool. Very depressing and hard to keep making it worth it.

It could be that the coolant leak was bad enough to get the engine warm and something in this engine seized from swelling from the heat.
I have had engines seize on me before and I waited for them to cool down, fixed whatever the external problems were and then turned it backwards to release whatever the problem was.
One time I had a headgasket go on a mercedes engine and coolant got in the oil and a bearing caught on the crank and spun, I just flushed it, put new oil, put some radiator seal in the radiator, and then I turned the crank backwards which released it and then I fired it up, it ran for another year before having problems.
Your's I am guessing is a new rebuild so tolerances might be tight, and a little heat expansion could have been the problem.
On the other hand if it was a bad rebuild, or a bad oiling system, then you are SOL
 
It wasn't a rebuilt engine, just one I recently picked up and freshened up.

I'm parting the truck out now, gonna use my 80 K25 as the new wheeling rig... If anyone is needing any 6.2L parts, lemme know.
 
I figure I spent around a grand on the engine, including buying it.

I'm keeping some parts as spares for my 80, but much of it I've listed for sale. I'm hanging onto the girdle for later, as I'm sure there will be another 6.2L in my life sooner than later, lol

why don't you just put a new set of bearings in and change the crank? i have a crank here

I agree, especially after seing the for sale thread, oh my god you spent too much money already, you are almost there now.
I too have a crank here but obviously one in Canada will be cheaper for you. :D
 
Well, Iceman talked some sense(?) into me, I do have a crapload of money invested in this, and giving it all away at a fraction of what I paid for it all isn't worth it. I'm going to replace the engine yet again, I have almost all the materials on hand between the two engines. The only requirement is that that old engine has to have a problem with the head causing low compression, or I'll be looking for yet another new engine....
 
Oh darn, I was gonna buy all my parts back at half price,, lol

pull the seized engine ane drop the pan. chances are nothing broke dieing at an idle. if rods look good, new crank bearings and pump. chances are, it had a bad bearing for a while, but you couldn't hear the knock in time with the clacking of the diesel
