The issue

On certain buses equipped with a Cummins ISC/ISL engine, improper installation of a boss plug during engine assembly could create stresses in the cylinder block casting. These stresses could eventually create open cracks in the cylinder block or result in less than adequate clamping pressure around the plug. When the plug loses it's clamping pressure, it will loosen from the cavity, causing an oil leak. This leakage of oil near the exhaust manifold and turbocharger has the potential to ignite and cause a fire in the engine compartment. Correction: Cummins will contact owner and to install a steel cup plug boss cap which is attached over the boss/cup plug location with an industrial sealant.

Description (français)

Sur certains autobus équipés d'un moteur Cummins ISC/ISL, un bouchon de bossage mal installé pendant le montage du moteur pourrait causer des contraintes dans le bloc moteur. Celles ci pourraient éventuellement provoquer des fissures ouvertes dans le bloc cylindres ou faire diminuer la pression de serrage autour du bouchon à un seuil inférieur au niveau adéquat. Lorsque le bouchon perd sa pression de serrage, il se dévisse, ce qui provoque une fuite d'huile. Cette huile, près du collecteur d'échappement et du turbocompresseur, pourrait s'enflammer et provoquer un incendie dans le compartiment moteur. Correction : La compagnie Cummins devra contacter les propriétaires et poser un bouchon de bossage en acier sur lequel on aura appliqué du scellant industriel.
