Reading some threads on here how one motor can take a beating and the next seems to puke out gaskets, cranks, pistons etc, got me thinking On the new sisu engines that agco is using each engine has the name of the final engine assembler/inspector engraved on the side plate. Each connecting rod is weighted and stamped with a marking to correspond with that weight. I had one of the guys who works at a rather large dealership tell me that when Agco switched from the cummings to Sisu their engine warranty claims went down significantly. Maybe this is something more companies should do so that the quality control would maybe improve.
