So I have taken apart my 7.3 idi that was rebuild 50,000 miles ago or so the guy I bought it from says. I believe him as the bearings all are in excellent condition. the problem is one of the pistons has a crack on the face of it. Seen in the image below. Other than that engine seems in great health. Wondering if that is a problem. The block is bored 30 over and if this is a problem and requires new pistons I will probably be sleeving the block. If you have any input it would be greatly appreciated. Thanks
