Nothing is gonna give in this area if a decent repair is done. Total force exerted from the oil in that small break area is in the range of 5-10 lbs max in the effected area and the bearing will be well supported by the remaining material. And the above does not count the cost of machine work that may have gone into the block at this point; those $$ would be thrown away. Plus the time to dig out a new one and re-work it fresh.... not every one lives near to a boneyard. I'd fix it for sure..... and have done so with more damage in blocks, as I knew the rest of the block was a known, good item and was in hand, ready to go.
