    244,000 miles on my beast, a '96 GMC K2500 only thing changed out on motor was injectors at 240,000 miles first time, oil pressure switch and obviously a PMD. I also changed the turbo to larger freer flowing one cause the gm turbos are junk and most likely would have killed my motor by now cause of high drive pressure. Im basically running an all original motor.

    For piece of mind im soon gonna swap out the harmonic damper and crank pulley and possible timing set

    She started her life out hauling freight from the West Coast to the East Coast doing weekly rounders.
    Today she is my daily driver (usually), still well taken care of (probably better than the wife- could be why I am divorced too).

    1,330,000 km's and still going strong
    If it fit in the bed, the wife would sleep in the garage :P

    My rig turned 300K this morning:





    No real major problems at all. Just normal stuff like several FSD's, one injection pump, alternator, A/C compressor, couple of starters, etc. Never touched the engine internals or even had to replace a glow plug yet.

    I've owned the rig since 174K were on the clock. I think it had one injection pump during that time as well.
