Considering the crank failure, I would think seriously about sending it to the manufacturer, or purchase a new harmonic damper. You do not want to go tto all the expense of a new crank, possibly some con rods, block machining and full rebuild and have it fail again down the road. It is not likely the cause was the damper, but just to have that peace in your heart.Aside from some marks as a result of interference with the water pump (assuming it occurred when the crankshaft became compromised and it wobbles) the damper looks fine to my eyes.
