Fix for cracked block on 6.2l diesel

I have a 1986 M1009 Blazer that has just developed a coolant leak from
the engine block. I can see coolant oozing out of the cast iron block
about 3 inches above the freeze-out plug right behind where the oil
dipstick tube runs down along the block. There is not visible crack but
nevertheless the block must be cracked. Is this a known problem with
the 6.2 l GM diesel, and can anyone offer any suggestions on how I can
remedy this problem (other than the obvious solution which is to get a
new engine).

Any help would be appreciated.
