Mitsubishi L100 4G63 Timing Chain Tensioner Failure
Most affected vehicles
Mitsubishi L100 2.0 Van, Pickup, Panel Van (1996-2007, 4G63)
Failure mileage range
100,000-140,000 miles
Typical failure window
Root cause
Original tensioner (MB062044) loses hydraulic pressure, allowing chain slack that damages guides and sprockets.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Tensioner Replacement | £800 - £1,200 | £500 - £800 | Replace tensioner, chain, guides before catastrophic failure | Viable only if caught early; prevents engine damage |
| Full Replacement - Rebuilt 4G63 Engine | £3,500 - £4,200 | £2,400 - £2,800 | Supply & fit rebuilt long block with upgraded tensioner, bench tested, 12-month warranty | Best value for engines over 120k miles or with damage |
Our recommendation
On a Mitsubishi L100 worth £3,000-£6,000, preventative tensioner replacement makes sense if caught before rattling starts. Once noise appears, replacement is usually more economical than repair.
