1985 Chevrolet C 10 5.7L Petrol · B750 ODL

A clear pattern of chronic suspension bush wear and minor fluid seepage has emerged across both recorded DVSA tests for this 1985 Chevrolet C10, with the 2024 examination expanding the concern to include corrosion on the rear brake pipes. The most recent test on 26 July 2024 produced a Pass, but the advisory list was longer than the prior year's, signalling that the underlying mechanical condition is not stable but is gradually accruing new defects. Both nearside and offside front suspension arm pins or bushes have been flagged at consecutive tests, indicating ongoing wear to the front linkage rather than a one-off observation. The newly flagged rear brake pipe corrosion on both sides is a particular point of note, as this represents a safety-critical system component that warrants close physical inspection before purchase. The persistent oil leak, although classed as not excessive, has now appeared twice and merits monitoring for any worsening rate between tests. With only 6,158 miles recorded over approximately 41 years, this vehicle has averaged around 150 miles annually, an exceptionally low figure that points strongly towards extended periods of standing rather than regular road use. While low accumulation can preserve major drivetrain components from wear, it typically accelerates deterioration of rubber elements, seals, brake hydraulic systems, and exposed underbody metalwork through lack of use. The five-year gap between the 2024 test and the prior 2023 examination is the only recorded testing history supplied, so it is difficult to confirm whether the vehicle has been continuously road-registered or has spent considerable time off the road between MOT cycles. Buyers should treat the low recorded mileage with caution, as standing vehicles commonly suffer from perished hoses, dried-out brake fluid, seized calipers, corroded brake lines, and degraded suspension bushes precisely because these components require periodic operation to remain serviceable. On a physical inspection, particular attention should be directed at the front suspension arm pins and bushes, which have been advisory at both tests. With the vehicle on a ramp, check for any free play or rotational movement at the pivot pins, and listen for knocking or clonking noises from the front end when traversing speed bumps or uneven surfaces at low speed. The rear brake pipes, now flagged for corrosion on both sides, should be examined closely for surface rust, pitting, or any thinning of the metal, particularly along their length and at the threaded unions where they meet flexible hoses, as heavily corroded pipes will eventually fail and require replacement. Given the persistent oil leak advisory, a thorough underbody examination is warranted to identify the source, whether from the engine sump, valve cover gasket, or rear main seal, and to confirm that no oil is reaching the exhaust system where it would produce visible smoke on start-up or under load. During the test drive, the brake pedal should feel firm and progressive without excessive travel, sponginess, or any pulling to one side under braking, as corroded rear brake pipes can compromise hydraulic integrity and uneven caliper function may become apparent after periods of disuse. Steering response should be checked for any vagueness, clunks, or wandering, which would suggest that the worn front bushes have progressed beyond advisory level. The engine should be observed both from cold start and at operating temperature for any signs of worsening oil leakage, excessive smoke, or rough running, as a long-standing leak combined with minimal use can indicate degraded gaskets and seals. Finally, given the chronic advisory pattern, budgeting for replacement of the front suspension bushes and rear brake pipe sections in the near term would be a prudent step before committing to purchase.
