    A while??? If it’s bad it’s highly likely going to keep destroying other components probably leading to an overhaul

    1 bad injector, 1 almost failing injector
    1 messed up piston

    seems like we need an inframe

    Depending on the condition of the rest of the engine you could just do one cylinder
    I would put in a good word for pai brand for aftermarket parts for cummins engines of that vintage.

    We are cleaning everything up so we can get an idea … hoping its only that piston, thats bad..

    injectors had some rust in them , as well as one head … someone had a heating problem that did not disclose to us it seems..

    I can get cummins brand around the same price as pai down here , some places cheaper .. fp and mcbee around the same , so might go with who ever has it in hand and gives me a 30 days store credit so we can get it back to work and recover that money

    thanks
     
    CellNet and W923 Thank this.

    Pretty sure pai has a year more warranty
    But I wouldn’t let that stop me from buying whatever of those brands I could put my hands on
