Common Problems
Mitsubishi Eclipse Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Mitsubishi Eclipse spans iconic turbo petrols and modern efficient units, but key failure patterns drive replacement demand. The 4G63 turbo's crank walk, 6G72 V6 timing belt risks, and Eclipse Cross 4B40 oil consumption dominate UK enquiries. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the...

Failure mileage range
80,000-120,000 miles
Typical failure window
Root cause
Thin factory thrust bearings wear under high load, allowing crankshaft end-play that destroys the block.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Bearing Inspection | £400 - £800 | £250 - £500 | Oil pan drop, bearing clearance check, oil pump screen clean | Only viable before knock appears; catches early wear |
| Full Replacement - Rebuilt 4G63T Engine | £4,500 - £7,000 | £1,800 - £4,500 | Supply & fit rebuilt engine with upgraded thrust bearings, bench tested, 12-month warranty | Permanent solution; upgraded components prevent repeat failure |
Our recommendation
On a 2G Eclipse valued under £3,000, replacement with a rebuilt 4G63T featuring upgraded bearings offers better long-term value than chasing a preventative fix on a worn block. We recommend replacement once any knock is detected.
