Common Failure
Known for injector seal leaks leading to oil dilution and blocked oil pickup strainers, triggering error code P06DE and low oil pressure warnings . Timing chain stretch and DPF regeneration issues are also widely reported .
The Mazda 6 2.2 Skyactiv-D (S8) is a capable twin-turbo diesel, but it has well-documented weak points that can drive replacement decisions: injector seal leaks causing oil dilution, timing chain stretch, DPF blockage, and turbocharger failure. Rebuilt engines through EnginesMarket include upgraded components addressing these failure points, plus a minimum 12-month unlimited-mileage warranty.
Why the Mazda 6 2.2 Skyactiv-D Fails
Affected Vehicles
Mazda 6 2.2 Skyactiv-D (S8, S8-DPTA, SHY1, 2012-2024)
Typical Failure Mileage
60,000-130,000 miles
Root Cause
The 2.2 Skyactiv-D can suffer from leaking injector seals due to combustion gas ingress and incorrect torque on early models. Early vehicles used copper injector sealing washers which were later revised to tinned copper with a specific 14Nm tightening procedure . Leaking seals allow combustion gases to enter the injector shaft, mixing with engine oil and forming carbonaceous residue. This residue blocks the oil pickup strainer, causing oil starvation and the P06DE "death code" - often leading to complete engine seizure .

Vehicle Value Check
A typical 2016-2018 Mazda 6 2.2 Skyactiv-D with 60k-100k miles is worth approximately £7,000-£14,000 [INDUSTRY ESTIMATE]. - Vehicle worth under ~£5,000: injector seal replacement is usually the best option - Vehicle worth ~£5,000-£8,000: evaluate both; repair is viable if no bottom-end damage - Vehicle worth ~£8,000-£12,000: reconditioned/rebuilt usually justifies the premium via warranty - Vehicle worth £12,000+: replacement cost is typically small relative to vehicle value
Our Recommendation
Our Recommendation
If your Mazda 6 2.2 Skyactiv-D displays the "Low Oil Pressure" warning or error code P06DE, have a specialist inspect the injector seals and oil pickup strainer immediately . Continuing to drive with this fault can lead to complete engine seizure. The revised tinned copper injector seals are a permanent fix when installed with the correct 14Nm torque procedure .
Don't Let Engine Failure Write Off Your Mazda 6 2.2 Skyactiv-D
The Mazda 6 2.2 Skyactiv-D is a capable, economical diesel saloon, but its injector seal, DPF, and timing chain systems require careful attention. A full rebuilt engine from EnginesMarket includes upgraded components addressing these failure points, backed by a minimum 12-month unlimited-mileage warranty. Compare quotes across used, reconditioned and rebuilt options - and get the work done by specialists, not main dealers.

Mazda 6 2.2 Skyactiv-D Engine ReplacementFrequently Asked Questions
Question 1How much does a Mazda 6 2.2 Skyactiv-D engine replacement cost-
A used Mazda 6 2.2 Skyactiv-D engine (S8/S8-DPTA) costs £400-£1,200 supply-only, while a reconditioned unit is £1,200-£2,200 and a full rebuilt engine £2,000-£3,800 [ESTIMATED]. Fitted costs add £520-£650 labour at a specialist. Compare quotes through EnginesMarket to find the best deal for your exact year and mileage.
- Used: £400-£1,200 supply-only
- Reconditioned: £1,200-£2,200 supply-only
- Rebuilt: £2,000-£3,800 supply-only
Question 2What are the signs of injector seal failure in a Mazda 6 2.2 Skyactiv-D-
Symptoms include the "Low Oil Pressure" warning on the dashboard, error code P06DE, poor acceleration, limp mode, and rising oil level on the dipstick . Continuing to drive with this fault can lead to complete engine seizure due to oil starvation caused by blocked oil pickup strainers. If you notice these symptoms, have a specialist inspect the injector seals immediately. A Mazda recall (2013-2018) addressed injector seal torque issues but many vehicles remain affected .
- "Low Oil Pressure" warning light
- Error code P06DE
- Rising oil level (fuel contamination)
- Poor acceleration or limp mode
Question 3Is it worth replacing the engine in a Mazda 6 2.2 Skyactiv-D-
A full rebuilt S8 engine costs around £2,000-£3,800 supply-only [ESTIMATED]. For a 2016-2018 Mazda 6 2.2 Skyactiv-D worth £7,000-£14,000, replacement is typically financially sensible - especially with a 12-month warranty. However, if injector seal failure is caught early, a repair kit and oil pickup clean can be far cheaper. Some owners have had engines replaced under Mazda Australia warranty even on out-of-warranty vehicles with full service history .
- 2016-2018 values £7,000-£14,000: replacement viable
- Catch injector seal issues early for cheaper repair
- Mazda warranty replacements are possible with full service history
Question 4How long does a Mazda 6 2.2 Skyactiv-D engine replacement take-
A specialist workshop typically completes a full S8 engine swap in 10-14 hours. With parts sourcing and delivery factored in, allow 2-4 days from quote to car back on the road. Supply & fit options through EnginesMarket streamline the process by pairing you with a specialist who has the engine in stock.
- 10-14 hours specialist labour
- 2-4 days typical turnaround
- Supply & fit options available
Question 5What's the difference between the Mazda 6 2.2 Skyactiv-D and the 2.0/2.5 petrol engines-
The 2.2 Skyactiv-D produces 150-184hp and 380-450Nm, while the 2.0 petrol produces 160-165hp and the 2.5 petrol 194hp. The diesel is significantly more economical (4.5-5.6 L/100km vs 6.0-7.2 L/100km for petrol) but has known failure issues including injector seal leaks, DPF problems and turbo failure . Petrol engines are considered far more reliable with fewer standard issues - the Mazda 6 2.2 Skyactiv-D has been described by some owners as "the worst engine Mazda has ever designed" .
- 2.2 Diesel: 150-184hp, 380-450Nm, 4.5-5.6 L/100km
- 2.0 Petrol: 160-165hp, 6.0-7.2 L/100km
- 2.5 Petrol: 194hp, 6.4-7.2 L/100km
Question 6Does the Mazda 6 2.2 Skyactiv-D have a timing belt or chain-
The Mazda 6 2.2 Skyactiv-D uses a timing chain, not a belt . This is confirmed by Mazda's workshop manuals and parts catalogues - the chain is described as maintenance-free under normal operation . The chain does not have a routine replacement interval, but can stretch on higher-mileage examples - particularly if oil changes are neglected or fuel contamination occurs . Rattle on cold start or fault codes for cam/crank correlation are early warning signs.
- Timing chain, not belt
- No routine replacement interval
- Regular oil changes essential for chain life
Question 7What engine codes fit my Mazda 6 2.2 Skyactiv-D-
The 2.2 Skyactiv-D was fitted with several engine codes across Mazda 6 generations: S8 (150hp, GJ generation), S8-DPTA (175hp, GJ generation), SHY1 (GJ/GL generation) and SHY2 . Always verify your engine code on the engine block or V5C before ordering - GJ and GL generation components may not be directly interchangeable without adaptation. The Mazda 6 (GJ, GL) 2.2 D chassis codes include GJ2FP, GJ1021, GJ1022, GL1021 .
- S8: GJ generation, 150hp
- S8-DPTA: GJ generation, 175hp
- SHY1: GJ/GL generation
- SHY2: GL generation
