This filing is one of 15 Isuzu notifications from 2003 in this archive.

Defect
In the engine fuel injection system, the O-rings around the injectors have insufficient heat resistance. Age-related deterioration degrades their sealing performance, allowing fuel to mix into the engine oil and causing the oil pan level to rise abnormally. Continued use allows the fuel-contaminated oil to enter the intake manifold through the blow-by hose, causing engine speed to increase uncontrollably.
Corrective action
On all vehicles, replace the affected O-rings with the corrected parts.

状況
原動機の燃料噴射装置において、インジェクタ回りのオーリングの耐熱性が不十分なた め、経時劣化によりシール性能が低下して、燃料がエンジンオイルに混入しオイルパン油 量が増大するものがあり、そのままの状態で使用を続けるとブローバイホースを通して吸 気管に燃料の混入したオイルが入り、原動機の回転が上昇するおそれがある。
改善措置
全車両、当該オーリングを対策品に交換する。
