Have had really bad luck with International engines (2004 & 2007) and looking at buying a couple of used Mack dump trucks, 2006-2016. Are these MP8-455 good solid engines? We've had some older Mack trucks with Mack engines in the past, and we had good luck with them. They weren't new, by any means, when we got them. Those were 1979 (300 plus) & 1984 (350). Are the newer Mack emissions dependable or are they having trouble with them?
