Did water collect in the jacket and crack the block?

tractor was drained but there could have been some in the bottom

I have seen a few 620 and 630 with cracks on the block bottoms for no apparent reason. They are really thin there too I think.

This is a very tiny crack. Can't see it until it oozes. JB has stopped it so we will see what happens after I fire it up. Thanks for the response

Have seen 730D crack across the bottom.
Stress not frozen.
