Looks like I must have missed it multiple times as looking back I don't see it. Metal water pump impellers can machine the block which would be visible in the block after the water pump is removed. I did not find that shot in the pictures provided. If the block was machined by a metal impeller, metal in the coolant passages could be expected. This could obstruct the coolant flow resulting in specific areas of the engine overheating. In any event to me, finding FOD in the coolant passages indicates a complete tear down to clean out the coolant galleys. That's a big deal, but allows building the engine up from the crank out. My engine had 120k on it, and the bearings were shot with dealer service intervals / Mobile 1 oil changes as recommended by Porsche. The timing chains off the IMS can also be changed if the block is split which is a benefit.
