The International dt 466 school bus engine suddenly experienced extreme performance degradation without any warning while driving. The engine started a popping noise and severely lacked power. We purchased 75 school buses in 2008, and 26 percent of them had roller tappet guides fail by February 2013. In every case, this failure mode resulted in major damage to engine valve train components. Two engines out of 26 total failures to date were not repairable and required replacement. The current failure has now grown to 34 percent. It is a safety hazard to school children and other vehicles when a school bus engine suddenly experiences severe engine degradation on the road.
