Just bought this 89 cherokee knowing this might be here but never expected to see it this bad.



About 8" from water pump back on DS

 

Is it running?

 

Actually ran quite well id say, only around the block a few times. Temp light came on and I parked it to investigate.

 

Nice.

 

Reminds me of different engines i seen crack from running straight water and it froze in the winter time.

 

If engine still runs why not weld it up with a stick welder, with the right rods, just clean up the crack a little and then just fix it.
Over the years I have done it a few times with different engines with frozen engine blocks, one engine in a forklift truck ran for 15+ years with a welded crack and it was used every day for loading and unloading trucks.

 

I am thinking about trying it with my TIG Ive become decent at welding cast aluminum, but haven't tried steel yet. I have been told to get nickle rod, but this crack is more than a crack its started pulling apart so where will it stress crack next??????? I am still replacing it for one less thing to worry about.

 

The block is way too thin there. Been there, tried that, got the t-shirt.

 

Don't you have all the t-shirts by now?

 

Pretty much. And, I never wear t-shirts!!!!

 

To thin to weld? Not suprising new table base!!!!!

 

try using silican bronze rod if you are going to tig it, I think that's would work, maybe grind just a very small v in it very small and let the silican brone fill it
