4M40 Timing Chain Failure
Most affected vehicles
Mitsubishi Pajero 2.8 TD (1994-2006, 4M40 & 4M40-T)
Failure mileage range
60,000-100,000 miles
Typical failure window
Root cause
Hydraulic tensioner wear allows chain slack, causing rattling at 2,500rpm and eventual jump/skip.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Chain Kit | £1,800 - £2,400 | £1,200 - £1,600 | Replace chain, guides, tensioner before catastrophic jump | Viable only if caught early; does not fix pre-existing damage |
| Intermediate - Head Inspection | £2,200 - £3,000 | £1,500 - £2,100 | Strip top end, check for valve/piston contact after chain jump | Only if damage is superficial; risk of hidden cracks remains |
| Full Replacement - Rebuilt Engine | £4,500 - £6,000 | £2,600 - £3,000 | Supply & fit rebuilt 4M40 with upgraded tensioner, bench-tested, 12-month warranty | Best value when chain has jumped; eliminates repeat failure risk |
Our recommendation
If you hear the characteristic "chuff chuff" at 2,500rpm, act immediately. On a Pajero worth under £4,000, a preventative chain kit from a specialist offers the best balance of cost and reliability. If the chain has already jumped, replacement with a rebuilt unit is almost always more economical than extensive repairs.
