Toasted 2003 LB7 in C4500
was getting the dreaded smoke at Idle for about 1 maybe 2 week was during the real cold weather, figured was injectors already had 2 set one at 67,000 second set at 132,000 now at 165,00 was driving to dealership Friday to set up appointment 4 miles before got there she let out a large cloud of back smoke and started shaking, pulled over pulled it my tech 2 (I'm a fleet tech) gave me code for #7 injector failure, so limped in to dealer ship parked it found oil dripping out the breather. left truck they called Monday no compression #7 pulled injector used bore scope chunk missing out of the piston trashed wall,
oil and fuel filter changed ever 7500 miles
so now new engine or new truck this is a C4500 with service truck body on it
I asked the dealer can we test the injector to see if it had a bad tip spray on one spot and did it lead to this failure there not sure of course.
has anyone else seen any do this or heard of this type failure thanks
