The recent 59AB block I did had a rot hole in the lower portion of the water jacket. Hole was the size of the pencil eraser
We did not find it until it was baked and blasted. It was caused by a ton of crap that settled in the water jackets and left in there and eventually ate through the cast iron. We epoxied the inside and out using Belzona 1212 epoxy.
