markpwhit Posted March 13, 2017 Share Posted March 13, 2017 Looking at an 09 Granite tri-axle dump and it has a 415 HP MP8 motor. Looking on feedback on how reliable/problem free these motors are. Mileage is listed at around 150K. Any experiences/feedback would be greatly appreciated. Just trying to avoid buying something that will full of headaches.

bulldog52 Posted March 13, 2017 Share Posted March 13, 2017 We have 3 trucks with MP7 405s in them and bought a 2013 with an MP8 415 that we're actually scared to use because of our experience with the MP7. Engines seem to have decent power when they run and return ok fuel economy for the kind of work we do. All 3 MP7s have had multiple problems. Constantly dealing with sensor failures, oil wicking in the harnesses, one fuel injection harness, 1 complete turbo, 2 turbo actuators, 2 camshafts, 1 engine fan, belt tensioners, 2 transmissions, 1 egr cooler, and most recently a fuel filter base followed by a fuel hose from the crossover to the ECM cooling plate.
