1996 Mitsubishi Delica 2.8L Diesel · P978 YAE

A clear pattern of corrosion-related advisories and front-end wear defines the mechanical story of this thirty-year-old Mitsubishi, with the most recent test on 4 December 2023 returning a pass alongside several items that warrant close scrutiny. Recurring advisories over the 2021 to 2023 testing window paint a consistent picture: brake pipe corrosion, subframe mounting corrosion, exhaust leakage, and nearside front tyre edge wear have all been flagged multiple times. The October 2023 failure was remedied quickly within the same testing cycle, suggesting the defects were relatively minor at that stage, though the identical advisories appearing on the subsequent December 2023 pass indicate that none of these wear points were fully resolved and remain ongoing concerns. The persistence of subframe corrosion advisories on both nearside and offside fronts is particularly noteworthy, as these structural mounting points are common failure zones on older chassis and can deteriorate further between tests if untreated. Against the vehicle's thirty-year lifespan, the recorded 125,820 miles equates to an average of around 4,194 miles per year, which is markedly low for a commercial-derived vehicle of this age. The MOT records themselves show testing gaps between 2021 and 2022 and again before the 2023 entries, but no multi-year absence from testing is evident, suggesting the vehicle has remained in use rather than being laid up for extended periods. That said, a low annual mileage figure on a chassis of this vintage almost certainly reflects prolonged stationary intervals, which tend to accelerate corrosion on underbody components, brake lines, and exhaust systems due to moisture retention and lack of regular protective wear on moving parts. The clustering of corrosion advisories on the subframe, footstep frames, brake pipes, and exhaust supports this interpretation, as these are precisely the components that suffer when a vehicle sees light, intermittent use rather than consistent mileage accumulation. For a prospective buyer, the priority inspection areas are clearly defined by the advisory history and warrant careful physical examination rather than a cursory visual once-over. The nearside front subframe mounting should be probed with a screwdriver or wire brush to confirm that surface corrosion has not advanced into the structural prescribed area, as corrosion advisories can rapidly progress to failure between MOTs if left untreated. The brake pipes, particularly the offside front line previously flagged with corrosion, should be inspected along their full length for pitting, flaking, and any weeping of brake fluid, with a focus on unions and brackets where rust tends to form first. On the test drive, listen for any knocking or clonking from the front suspension over uneven surfaces, which could indicate advanced wear on the offside front shock absorber bush or the nearside rear upper suspension arm previously flagged for corrosion, and pay particular attention to any steering vagueness or noise that might suggest progression of the offside front wheel bearing play noted in earlier tests. The tyre condition also deserves focused attention, as nearside front edge wear has been flagged repeatedly and is symptomatic of either alignment geometry drift, worn suspension components, or a combination of both. A thorough alignment check should be requested, ideally accompanied by an inspection of the front strut top mounts, track rod ends, and lower ball joints for any free play. The oil leak previously noted, while classed as not excessive, should be traced to its origin, as ageing gaskets and seals on a low-mileage vehicle can weep more noticeably once the engine is returned to regular service after long idle periods. Finally, the exhaust system should be examined on a cold start for any audible gas escape, and the footstep frames checked for structural integrity, as corrosion in these areas will eventually compromise their load-bearing function and could lead to future MOT failure if not addressed promptly.
