DT466e, T444E, Cummins 5.9L or 8.3L, CAT 3126, all from 2003 or earlier are near-universally considered good, reliable engines. These engines from 2004 to 2006 are maybe alright (the CAT became the CAT 7 in this period), but opinions on that are more variable. 2007 or newer are when things start to get pretty dicey. MaxxForce, Ford 6.0L and VT365 are generally regarded as the worst of the worst.
