    I’ve had a similar experience/problem with mine. It made it to 745k miles, but blew 3 cylinder sleeves about 2 weeks after DPF delete. Also, I’m being told that the Detroit DD15 motors are only lasting approximately 100k miles post rebuild. Apparently, Detroit is aware of this problem and unwilling to take responsibility for it. I’m told that following the rebuild of the motor, the lower rear bearings lock up. Has anyone else heard of this?

    I also had same thing happen 2 weeks after delete. A cylinder sleeve let go, was told later that the EGR shouldn’t have been disabled. The shop that did the delete just went into ECM and moved switches. Now looking at used engines, I got a 2012 Cascadia with DD15, does anyone know if a 2014 engine will swap with the 2012??

    thanks

    Never had my DPF deleted on my 2012 cascadia dd15. Bought a year ago with roughly 830k just at 923k and engine oil pressure buzzer went off then it shutdown immediately seizing up. Oil levels were fine and still are.
    Engine won’t turn. Do I need another engine?

    You don't have a clue what you are talking about. Walmart takes excellent care of their trucks. How's that old prime truck working out for you?

    Quite likely. Detroits seem to have issues with oil pickup tube at the oilpump. Your description sounds like this and it ran dry.

    That doesn't usually happen suddenly though. There will usually be a low oil pressure warning first.

    That's what he said.

    That's exactly what a colleague of mine experienced. Oil pressure warning, buzzer, engine gone within a few seconds before she even could pull over. 60 000 Loonies later, she was back on the road with a sparkling new DD15.
