2003 Isuzu Trooper 3.0L Diesel · ST52 HOJ

Recurring issues with brake pipe corrosion and engine oil seepage define the mechanical profile of this vehicle, alongside a recent emergence of exhaust gas leakage. While the most recent test on 08 January 2026 resulted in a pass, the record shows a persistent pattern of advisories regarding non-excessive engine oil leaks dating back to 2021. The structural integrity of the braking system has been a specific point of failure, with a major defect recorded in December 2024 due to excessive corrosion on both the nearside and offside brake pipes. Although these were addressed to achieve the latest pass, the presence of a new advisory for a minor central exhaust leak suggests that while the braking system has been rectified, other peripheral components are beginning to show signs of degradation. The vehicle has covered 45,842 miles over its 23-year lifespan, representing an average annual accumulation of approximately 1,993 miles. This exceptionally low mileage suggests the vehicle has spent significant periods stationary or has been used only for very infrequent short-distance trips. From a mechanical standpoint, such a usage pattern can lead to the degradation of rubber components and the accumulation of corrosion on metal surfaces that are not regularly cleaned by road spray and airflow. The MOT history reflects this, with recurring advisories for worn tyres and corroded brake lines which are common in vehicles that undergo long periods of inactivity or limited seasonal use. Prospective buyers should pay close attention to the braking system and the engine bay during a physical inspection. Given the history of major failures regarding brake pipe corrosion, it is essential to inspect the entire length of the hydraulic lines for any signs of surface rust, scaling, or weeping fluid. On a test drive, pay close attention to the brake pedal feel; any sponginess, a soft pedal, or a pulsating sensation under braking could indicate air in the system or uneven disc wear. The recent advisory for a minor exhaust leak should also be investigated; listen for any rhythmic ticking or increased engine noise while the vehicle is idling or under acceleration, which may indicate a failing gasket or a split in the exhaust manifold or central pipe. The repeated advisories for oil leaks and the split nearside front outer drive shaft CV boot in 2021 necessitate a thorough check of the drivetrain and engine seals. Inspect the engine bay for fresh oil misting or active drips around the sump, rocker cover, or timing cover. During the test drive, listen for clicking or popping sounds when turning the steering wheel at low speeds, which could indicate that the CV joint or boot has not been sufficiently addressed or is failing again. Additionally, the recurring advisories for rear tyres being worn close to the legal limit or worn on the edges suggest a need to inspect the rear suspension bushes and alignment, as uneven tyre wear can often be a symptom of worn suspension components or incorrect camber settings.
