In your opinion, is this a problem that can be foreseen prior to starting a job like this? If not, is it something that is customarily brought up as a potential risk?

After the engine was disassembled and the bottom end exposed, could anything have been done to assess the cylinders with the block in situ and alert the mechanic to a potential problem before the engine was reassembled?
