Broken

[maxfli]

I have a 1993 k2500 4X4, that has experienced what I believe to be a catastrophic failure. My first impression is a broken crank. I'm currently attempting to get the oil pan off to see the damage, but am having a hell of a time with it. If I unbolt the front axle and transfer case, can I get this thing off? If I got to remove the motor mounts I might as well pull it. I'm trying to assess the damage to evaluate weather its worth fixing or scrap it. It's a really nice truck, with lots of new parts and work, but at the end of the day it's still a 93. can't put 5K in it.
Any advice?

Welcome aboard!

Dropping the differential will allow the pan to be removed.

You don't have to remove the pan to determine a broken crank. If there's any deflection between the flex plate or flywheel and the balancer, the crank is broken. Just index or lock the ring gear, put a breaker bar on the balancer bolt, and rock it.

Either way he pan has to come off. There are holes in it, and it was beaten pretty bad from the inside. Both sides up high and forward of the well. Had to beat it back in to get to some of the pan bolts. It's a mess.

Um, not really, unless you're just curious. Otherwise, it sounds pointless at this time, if you're not throwing your wallet into it.

In my opinion, being a 93 doesn't mean it it isn't worth fixing. If it's in great shape otherwise, dollar value is only relevant if/when you sell it. They're great trucks, if not beat up or rusted out. Read through these pages and you'll find a lot of folks throwing a lot more cash at less than what you have. It's an illness. Feed it or cure it.

I was pricing a long block from SSDiesel. It's about 5.5K, but it should be top notch. I've already got their injector pump on it. Has less than 5K miles on it. I just hate putting that much in a truck that's only worth 4K tops. Otherwise I could sell it on here to some of you enthusiasts and get some of my money back out of it. I bought it 2 yr ago for 4500 for my son, and he abandoned it. so I took it back. It is a good truck. I like it a lot, I'm just getting to the point I'm tired of working on stuff by myself, and to hire it done is definitely out of my budget.

What happened when it let go ????

I would not bother dropping the pan.

Yank the engine out and then dissect it and see whats salvageable.

Scare up a good block and piece together a decent engine.

I have pieced together several of these beasts over the years.

If you can salvage things like heads and and such you are on your way to making a runner cheap.

I have built some decent engines like this for less than $1000

ebay for stuff like rings, bearings, gaskets...
