Mitsubishi Eclipse Engine ReplacementRebuilt & Performance Options Available

Rebuilt Mitsubishi Eclipse engine prices range from £900 for early 1.8L units to £4,500 for 4G63T turbo or Eclipse Cross PHEV systems, depending on code, variant and condition type.

• 4G63T turbo rebuilds typically £1,800-£4,500 supply only
• Standard petrol engines (4G64/4G69) £1,200-£2,800 rebuilt
• Eclipse Cross 4B40/4N15 units £1,500-£4,200 depending on fuel type
• Supply & fit labour adds £450-£1,200 to engine price
• All EngineMarket quotes include minimum 12-month warranty

The 4G63T is robust when maintained but suffers crank walk bearing failure on 2G blocks (1995-1999) above 80k miles if oil changes are neglected or boost is excessive.

• Crank walk caused by thin factory thrust bearings wearing under load
• Regular synthetic oil changes every 3-5k miles critical for longevity
• Rebuilt units with upgraded bearings eliminate repeat failure risk
• Turbo components require separate inspection during replacement
• Strong aftermarket support aids maintenance and upgrades

Early 2018-2019 Eclipse Cross 4B40 engines suffer piston ring design flaws allowing oil into the combustion chamber; revised rings on post-2020 builds largely resolve the issue.

• Faulty rings permit excessive oil passage causing burning and carbon buildup
• Symptoms include blue exhaust smoke, frequent top-ups, fouled spark plugs
• Ring replacement possible but labour-intensive; rebuilt engine often better value
• Mitsubishi issued technical service bulletins but no formal recall in UK
• Use full synthetic 0W-20 oil and monitor levels closely on affected models

If the 6G72 timing belt snapped causing valve damage, replacement with a rebuilt unit is almost always more economical than attempting cylinder head repairs on this interference engine.

• 6G72 is interference design; belt snap bends valves and can damage pistons
• Head repair plus valve job often exceeds £2,500 with no warranty
• Rebuilt 6G72 engines £1,400-£3,200 with 12-month warranty included
• Factor in labour savings when choosing supply & fit rebuilt option
• Preventative belt replacement every 60k miles avoids catastrophic failure

Used engines can be cost-effective for project cars or low-value Eclipses, but always request compression test results and mileage verification before purchase.

• Used 4G63/4G64 units often £600-£1,800 vs £1,200+ for rebuilt
• Risk of hidden wear or imminent failure not visible on inspection
• Warranty typically limited to 1-3 months vs 12 months on rebuilt
• Ideal for short-term fixes, track builds, or cars valued under £2,000
• Always verify engine code matches your vehicle's DVLA record

Supply-only engines typically dispatch in 3-7 days; supply & fit installations require 1-2 additional days at a specialist garage, depending on parts availability and workshop schedule.

• Rebuilt engines often built to order; allow 5-10 days lead time
• Used engines may be available for next-day dispatch if in stock
• Supply & fit labour adds 1-2 days for removal, fitting and run-in
• Complex variants (GSX AWD, PHEV) may require longer specialist scheduling
• EngineMarket suppliers provide realistic timelines when quoting

Yes-every engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty covering parts and labour for manufacturing defects.

• Warranty valid UK-wide at any participating specialist garage
• Covers internal components, gaskets, seals and machining defects
• Excludes damage from misuse, incorrect installation or lack of maintenance
• Keep service records and use recommended oil to maintain coverage
• Confirm exact terms with your chosen supplier before ordering

Engine swaps are possible but require significant modification to wiring, ECU and mounts; for most owners, replacing with the original code offers the most reliable, warranty-backed solution.

• 4G63T into non-turbo Eclipse requires turbo plumbing, ECU and fuel upgrades
• Eclipse Cross engines not compatible with older coupe platforms
• DVLA may require notification and potential re-testing for major changes
• Specialist knowledge essential; DIY swaps risk reliability and insurance validity
• EngineMarket specialists can advise on feasible swap options if requested

The 4G69 2.4L MIVEC (2006-2012) and revised post-2020 4B40 1.5T offer the best balance of modern efficiency and proven reliability when maintained properly.

• 4G69 benefits from MIVEC efficiency and late-production refinements
• Post-2020 4B40 units feature revised piston rings addressing oil consumption
• Avoid early 2G 4G63T blocks (1995-1999) unless rebuilt with upgraded bearings
• Regular oil changes with quality synthetic are critical for any Eclipse engine
• Service history matters more than mileage for long-term reliability

Enter your registration number above for instant DVLA verification, or locate the engine code stamped on the block near the oil filter housing or on the vehicle's VIN plate.

• DVLA lookup via EngineMarket instantly confirms code, fuel type and variant
• Physical codes: 4G63/4G64 near oil filter; 6G72 on timing cover; 4B40 on valve cover
• Owner's manual and service records often list the factory-fitted code
• Eclipse Cross codes: 4B40 (petrol), 4N15 (diesel), 4B40+EM (PHEV)
• Matching the exact code ensures compatibility and warranty validity
