On certain school buses equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly molded rubber adapter to detach from the breather. This could allow engine oil to come in contact with hot surfaces, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will install clamps at both ends of the adapter of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.
