Mitsubishi Pajero Sport Timing Chain Malaysia — 4N15
4N15 uses a timing chain — no scheduled replacement. However, diesel soot contamination from missed oil changes causes chain tensioner wear and chain elongation. Change oil every 10,000 km with diesel-spec oil. Cold start rattle on a diesel typically indicates a worn chain or tensioner. On a diesel, chain replacement is a more significant job than on a petrol — preventive oil changes are the most cost-effective approach.
Pajero Sport Timing Chain
The 4N16 in the Pajero Sport uses a timing chain. Use correct low-SAPS diesel oil; do not use standard petrol engine oil or high-SAPS diesel oil as it accelerates chain wear and clogs the DPF. At 100,000 km, a visual inspection of chain slack is worthwhile during major service.
