Common Problems
MG Metro Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The MG Metro's A-Series and A-Plus petrol engines are generally robust but prone to classic failure patterns like head gasket degradation and timing chain wear. Every rebuilt engine supplied through EngineMarket includes upgraded MLS gaskets and cooling system inspection to address original weak points - plus a minimum 12-month unlimited mileage warranty.

Failure mileage range
60,000-90,000 miles
Typical failure window
Root cause
Thermal cycling causes standard composite gasket to degrade; classic cooling system layout exacerbates hot spots under modern traffic conditions.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Gasket Upgrade | £650 - £950 | £425 - £675 | MLS gasket replacement + cooling system flush + thermostat check | Viable only if caught early before overheating damage; adds 20-30k miles reliability |
| Full Replacement - Rebuilt A-Plus Engine | £2,800 - £3,600 | £1,245 - £2,100 | Complete rebuilt engine with upgraded MLS gasket, cooling inspection, bench testing, 12-month warranty | Best value for high-mileage Metros; addresses root cause and restores reliability |
Our recommendation
On a classic MG Metro worth £3,000-£8,000, a preventative gasket upgrade makes sense if the engine is otherwise sound. If overheating has already occurred or mileage exceeds 80k, a rebuilt A-Plus engine with warranty offers better long-term value and peace of mind.
