| MLIT filing number | 1214790 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | March 19, 2008 |
| Manufacturer(s) | Isuzu |
| Component | Fuel Injection System |
| Production period | March 16, 1998 — October 30, 2001 |
| Vehicles affected | 9,757 units |
Defect
The fuel injectors in the engine fuel injection system were designed with incorrect dimensional specifications. On some units, the clearance between the plunger and barrel is excessive, causing the O-ring to deform and sustain damage, which compromises the seal. As a result, diesel fuel may contaminate the engine oil. Continued operation allows the oil pan volume to increase. The diesel-contaminated oil is then drawn through the intake pipe via the blow-by hose, which may cause engine speed to rise uncontrollably.
Corrective action
On all vehicles, verify the injector serial numbers. On affected units, replace the injectors on all cylinders with corrected parts.

状況
原動機の燃料噴射装置において、インジェクタ（燃料噴射弁）の設計寸法が不適切なため、プランジャとバレルの隙間が大きいものがあり、オーリングが変形、損傷して気密性が損われ、燃料の軽油がエンジンオイルに混入するものがある。そのため、そのままの状態で使用を続けると、オイルパンの油量が増大し、ブローバイホースを経由して吸気管に軽油の混入したオイルが吸入され、原動機の回転が上昇するおそれがある。
改善措置
全車両、インジェクタのシリアル番号を確認し、対象となるものは全気筒のインジェクタを対策品と交換する。
