I was overhearing a Service advisor telling a owner operator with 454k’ You most likely have a Blown valve because compression is coming up thru the valve cover and mechanic recommends Overhaul , He was pissed’ How can it be that and engine can’t last 500k before and overhaul’ screw that I’m going out off business’ this is ridiculous ..
I feel for these guys’

Another one of My friends had better luck ‘ 2018 Kenworth X15 performance with 550 hpr just had total out frame by Cummins White Bear Lake, Mn $45,890.00
Camshaft Lobes were the original problem but He let it go kept running and it tore the rest of the engine up..

That is the results when you abuse and neglect your equipment... then blame the equipment. The repair shops .. especially the OEM stealers$its ... are no better any more these days either.
