This is the 3rd common rail I have built recently with this Cummins error. This is a late 2007 5.9 backed by a 6 speed manual. Notice the rod orientation upon dis-assembly. The rods are backwards. This engine only had 190k miles and had not been opened up on the bottom end since new. Engine failed due to broken rings on cylinders 1 and 4 caused by failed injectors. Truck is a 1 owner since new that knows complete history. I've also attached service instructions direct from Cummins Quickserve. Figured I would post for the Common Rail folks.
