I'm a Duramax man.180,000 miles and replaced nothing but three idler pulleys(only one went bad,didn't trust the other two) and the belt.It snapped when the pulley seized.hard to drive thru town with no power steering and 35s.
.Runs quiet enough I can still whisper in my girl's ear without hollering,too.My dad has a rattle-trap Ford with a 6.0.Loudloudloud.Swears he's buying a Chevy next.Dang 6.0 wants to run at 3000 rpm's all the time.No bottom-end in my opinion.BUT,my momma's Dodge is STOUT.If you can keep it in the road.Like driving with one front tire flat all the time.CHEVY all the way(even if it really is an Isuzu
ops: )!!!Of course my girl friend loves her 6.0,but what do women know......
