The Mitsubishi Raider's PowerTech petrol engines (3.7L V6, 4.7L V8) are generally robust but suffer from timing chain tensioner wear, oil sludge buildup, and coolant system leaks at higher mileage. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure point - plus a minimum 12-month...
Mitsubishi Raider Timing Chain Failure
Most affected vehicles
Mitsubishi Raider LS, SLT, R/T (2005-2009, PowerTech 3.7 & 4.7)
Failure mileage range
60,000-90,000 miles
Typical failure window
Root cause
Factory timing chain tensioners lose pressure over time, allowing chain slack that causes rattling, jumped timing, and catastrophic valve damage in this interference engine design.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Tensioner Replacement | £1,800 - £2,600 | £1,200 - £1,800 | Replace timing chain tensioners, guides, and seals before catastrophic failure | Adds 30k-50k miles if caught early; not viable after rattling starts |
| Full Replacement - Rebuilt PowerTech Engine | £4,500 - £6,500 | £2,200 - £3,400 | Supply & fit rebuilt engine with upgraded tensioners, water pump, bench tested, 12-month warranty | Restores like-new reliability; best value for high-mileage grey imports |
Our recommendation
If your Raider is under 70k miles and you hear early chain rattle, preventative tensioner replacement may be cost-effective. However, once timing has jumped or valves are damaged, full engine replacement is the only viable option - and rebuilt units with upgraded components offer better long-term value than repeated repairs on a 15+ year old grey import.
