Well i am one of those guilty people that can not keep his finger out of things and i have turned up diesels with bigger pump settings bigger turbos and may be just lucky that i never dropped a valve or put a rod out the side or broke a crank , but have seen stock engines that for no reason drop a valve or a head of a valve come off . Man made the engine and there for it will break . The last truck that i was driving started life as a 475 3406 cat but was uprateable to 550 well that was done then it was uped angain with a new after market chip that took it over 700 hp and it ran fine for me but it did not run as well as and old 350 small cam cummins that i worked over as it was faster on the same hills with the same weight as the cat . So why the cat ate a valve is anybodys guess it fall under the heading THAT SHUTT HAPPENS . IT's broke now so ya got to fix it. valves are not made from one pice of steel the heads are welded on so it may just have been a bad weld or a spring broke can't say with out seeing all the pices and parts.
