Common Problems
Mitsubishi Colt Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Mitsubishi Colt's most common replacement enquiries centre on the 1.1L 3A91 timing chain, the 1.5 DI-D OM639 injectors, and head gasket issues on higher-mileage 1.3L 4A90 units. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure point - plus a minimum 12-month unlimited...

Failure mileage range
50,000-80,000 miles
Typical failure window
Root cause
Timing chain tensioner wear allows chain slack, causing rattle and potential jump, leading to valve timing loss.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Chain Kit | £650 - £950 | £425 - £695 | Chain, tensioner, guides replaced before catastrophic failure | Viable if caught early; 40k+ miles extension |
| Full Replacement - Rebuilt Engine | £1,450 - £2,100 | £395 - £895 | Complete rebuilt 3A91 unit with upgraded tensioner, bench-tested, warranty included | Best value for engines with existing damage; 12-month warranty |
Our recommendation
If your Colt 1.1 is rattling but still runs, a preventative chain kit from a specialist offers the best value. If the chain has jumped or valves are bent, a rebuilt engine at £395-£895 is far more economical than a dealer repair.
