Historical MOT pass rates and DVLA records for 1998 model year cars.
- Plastic Secondary Timing Chain Tensioner FailureSerious
Early 4.0-litre AJ26 and AJ27 V8 engines utilized first- and second-generation plastic-bodied secondary timing chain tensioners. Over repeated heat cycles and exposure to acidic engine oil, the plastic body develops stress fractures and the plastic shoe breaks off. This allows the secondary timing chain to slacken and skip teeth on the camshaft sprockets, causing piston-to-valve collision that results in bent valves and catastrophic engine destruction.
- Nikasil Cylinder Bore Lining Degradation & Compression LossSerious
Engines produced prior to August 2000 (engine numbers before 0008181043) used nickel-silicon carbide (Nikasil) electro-plated directly onto the aluminium cylinder bores. High sulphur levels in 1990s UK petrol reacted chemically with moisture to form sulphuric acid, eroding the microscopic Nikasil layer. This caused rapid ring wear, severe blow-by, bore wash, and terminal loss of cylinder compression when cold.
- Rear Suspension Subframe and Chassis Sill CorrosionSerious
The X100 chassis traps road mud, wet salt spray, and moisture behind the full-length plastic sill covers, inside the rear wheel arches, and across the fabricated rear subframe mounting points. Structural steel inner sills and front footwell floor outriggers corrode from the inside out. By the time bubbling paint appears externally, extensive structural welding is required to meet UK MOT requirements.
