Mazda 6 2.0-2.5 Petrol Engine Replacement (GG/GH) Compare Prices & Get Quotes

A Mazda 6 petrol (LF17, L5-VE) engine replacement typically costs between £750 and £2,200 for the engine supply alone, depending on whether you choose used, reconditioned, or rebuilt. Supply and fit adds approximately £390-£520 in specialist labour. Dealer pricing can add 30-50% to these figures.

• Used engine: £300-£700 supply only
• Reconditioned: £900-£1,600 supply only
• Rebuilt: £1,500-£2,200 supply only with 12-month warranty
• Typical labour: 6-8 hours at £65/hr indie rates

MZR petrol engines (LF17, L5-VE) are generally reliable but have three well-documented issues. Coil pack failure causes hesitation and misfires. VVT actuator wear causes cold-start rattle. Timing chain stretch on high-mileage units can occur if VVT issues are ignored .

• Coil pack failure is the most common issue
• VVT actuator rattle at cold start should be investigated
• Timing chain inspection recommended at high mileage

This depends on the vehicle's value and condition. A typical older Mazda 6 petrol is worth £1,000-£4,000. A rebuilt engine at £1,500-£2,200 may represent a significant portion of the vehicle's value. If the car is in good condition, well-maintained, and you intend to keep it for 2+ years, replacement is often worthwhile. If vehicle value is under £1,500, evaluate scrap value first.

• Vehicle under £1,500: scrap threshold - consider replacement only if car is otherwise perfect
• Vehicle £1,500-£3,000: evaluate both; used engine may be better value
• Vehicle £3,000+: replacement usually cost-effective
