Common Failure
Timing chain tensioner wear, particularly on higher-mileage examples. The MIVEC system can also experience solenoid failure affecting variable valve timing. Timing chain inspection recommended at 60k miles.
The Mitsubishi Outlander PHEV's 4B11 and 4B12 petrol engines are generally reliable but have known weak points. The 4B11 timing chain tensioner and the 4B12 oil consumption issues are the most common reasons owners seek replacement engines through our network. Rebuilt engines from EnginesMarket specialists include upgraded components addressing the original failure point, plus a minimum 12-month unlimited-mileage warranty.

Root Cause
The 4B11's timing chain tensioner can lose hydraulic pressure, leading to chain slack and eventual failure if not addressed. Cold-start rattle is the classic warning sign.

Vehicle Value Check
Vehicle Value Check
A typical Mitsubishi Outlander PHEV (2013-2018) currently values at £6,000-£14,000 depending on mileage, battery health, and specification. For vehicles under ~£8,000, a timing chain repair is almost always the better financial decision over a full replacement. For vehicles £8,000+, a reconditioned or rebuilt 4B11 engine with warranty usually justifies the premium - especially if the vehicle has good battery health and you plan to keep it 2+ years. Replacement cost is typically 20-40% of vehicle value in the mid-range.
Our Recommendation
Our Recommendation
If you catch the timing chain rattle early, replace the chain and tensioner - it's far cheaper than a full engine. If the chain has already snapped or caused damage, a rebuilt or reconditioned engine with warranty is the sensible choice for any Outlander PHEV worth over £6,000. For very high-mileage examples with poor battery health, consider the scrap value first.
Don't Let Engine Failure Write Off Your Mitsubishi Outlander PHEV
The 4B11 and 4B12 engines are fundamentally robust units. With proper preventative maintenance and early intervention at the first signs of chain rattle or oil consumption, most Outlander PHEVs can run well past 150,000 miles. But if the worst happens, EnginesMarket connects you with UK specialists who supply reconditioned and rebuilt units with upgraded components addressing the original failure points, backed by a minimum 12-month warranty - and all at a fraction of main dealer prices.

Mitsubishi Outlander PHEV Engine ReplacementFrequently Asked Questions
Question 1How much does a Mitsubishi Outlander PHEV engine replacement cost in the UK-
A reconditioned Mitsubishi Outlander PHEV engine typically costs £1,200-£4,500 supply-only, depending on whether you have the 4B11 (2.0L), 4B12 (2.4L), or 4N14 diesel. Fitted prices add £500-£1,100 for labour.
- Used engines: £600-£1,800
- Reconditioned: £1,200-£3,800
- Rebuilt with warranty: £1,800-£5,500
Question 2What are the signs of timing chain failure in a Mitsubishi Outlander PHEV 4B11-
The first and most common warning sign is a metallic rattle or clatter from the engine on cold start, lasting a few seconds before oil pressure builds. If ignored, you may hear a constant rattle, experience loss of power, and eventually the engine warning light will illuminate. Catastrophic failure results in the engine cutting out completely and potential valve/piston damage.
- Listen for cold-start rattle as the primary warning
- Check for metallic debris in the oil
- Don't ignore the warning - chain failure is engine-destroying
Question 3Is it worth replacing the engine in a Mitsubishi Outlander PHEV-
Yes, if the vehicle's value and condition justify the investment. A Mitsubishi Outlander PHEV with good battery health, low to medium mileage, and no other major issues is well worth replacing. For 2013-2018 models valued over £6,000, a rebuilt 4B11 engine (£1,800-£3,500 supply-only) is a sound investment. For 2018+ models with the 4B12 engine and values over £10,000, replacement is almost always financially sensible.
- Check your Outlander PHEV's current market value
- Consider battery health - if the battery is also failing, replacement may not be cost-effective
- A rebuilt engine with 12-month warranty can add 30,000-50,000 miles of reliable service
Question 4How long does a Mitsubishi Outlander PHEV engine replacement take-
A Mitsubishi Outlander PHEV engine replacement typically takes 8-12 hours for a specialist, so allow 1-2 working days for the job. Your vehicle will be off the road for this period.
- Most specialists can complete the job within 2 working days
- Some offer a collection and delivery service for convenience
- Supply-only engines are dispatched within 1-3 working days
Question 5What's the difference between the Mitsubishi Outlander PHEV 2.0L and 2.4L engines-
The key difference is displacement and power: the 4B11 (2013-2018) produces 118hp from 2.0L, while the 4B12 (2018-present) produces 135hp from 2.4L. The 4B12 is generally more robust and less prone to timing chain issues, but can suffer oil consumption from piston ring wear on higher-mileage units.
- 4B11: 118hp, older design, timing chain tensioner can fail
- 4B12: 135hp, more refined, oil consumption risk on high-mileage units
- Both are MIVEC petrol engines with very similar architecture
Question 6What warranty comes with a rebuilt Mitsubishi Outlander PHEV engine-
Every rebuilt and reconditioned engine supplied through EnginesMarket's UK network carries a minimum 12-month unlimited mileage warranty. Terms vary by specialist - some offer 24-month or 36-month warranties on premium rebuilds.
- 12-month unlimited mileage is the minimum standard
- Extended warranties available on some specialist rebuilds
- Always confirm exact warranty terms before ordering
