IC Bus Cesb Engine problems by year

Exhaust system failure,terible exhaust leaks AT EXHAUST MANIFOLDS. Pipes wrapped in insulation and metal causing high temps which are distoring pipe shapes and colapsing systems. Also a fire hazard if any fluids leak on them. These units are 2021's thru 2023's We have been in touch with International Dealer with no avail or help. They give all kinds of why's but no answers.

Engine exhaust head pipes before the catalytic converter melts down from excessive engine heat, creating a large exhaust hole. This is a school bus

THis is a school bus- Exhaust downpipes leading into the catalytic converters melted down and created large holes in the exhaust pipe itself. Extreme heat developed by engine.

This is a school bus. Exhaust down pipe from exhaust manifold melted down and created a large hole for fumes and potential fire from excessive heat/fuel issue in engine.

School Bus- Engine exhaust pipe from the exhaust manifold has melted from excessive heat in the system creating large hole for fumes and potential fire to escape. Exhaust is inadequate for the heat levels from the engine or engine performance is misprogrammed to create excessive heat/fuel. Widespread issue with many school buses in our fleet with the same powertrain.

School buses. We have a fleet of these and the condition is happening repeatedly and to almost every bus with this PSI brand 8.8L gasoline engine. The engine exhaust downpipes melt from excessive heat and/or fuel. The pipes then crack and produce an exhaust leak near the body firewall. Potential for exhaust and flame to escape from the pipe.
