Defect
On light-duty trucks, the cylinder head cover is incorrectly shaped, allowing rainwater to pool around the injector oil seal. The accumulated water causes the seal to swell, degrading its sealing performance. Continued operation in this condition allows engine oil to leak and, in the worst case, may result in engine damage.
Corrective action
On all vehicles, replace the cylinder head cover assembly with a corrected part. Inspect the engine oil; if water intrusion is found, flush the engine interior. Additionally, review vehicle driving data and replace the engine on any vehicle that may have sustained damage.

状況
小型トラックのエンジンにおいて、シリンダヘッドカバーの形状が不適切なため、インジェクタオイルシール部に雨水が滞留するものがある。そのため、オイルシールが膨張してシール性が低下し、そのままの状態で使用を続けると、エンジンオイルが漏れ、最悪の場合、エンジンが損傷するおそれがある。
改善措置
全車両、シリンダヘッドカバー一式を対策品に交換する。また、エンジンオイルを点検し、水浸入が確認されたものはエンジン内部を洗浄する。なお、車両走行データを確認し、ダメージを受けているおそれのある車両はエンジンを交換する。
