My company had a engine failure due to casting or erosion damage to cylinder wall. Poked a hole inside cylinder about 1/4 of the way down. Engine is in a nodwell. 2012 6.7QSB cummins with some pump drive and what not on the back. I had my doubts we would find an engine around and Sunny got back to me with an engine and had it shipped before Cummins even replied to my email. Good and fast service.
