Why R2 Engines Burn Oil
Production Years: 2003 - 2010
Engine: EN07E / EN07D / EN07X
Typical failure window
Piston ring wear and valve stem seal degradation allow oil to enter combustion chambers, causing blue exhaust smoke and frequent top-ups.
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Minor - Valve Stem Seal Replacement Minor | £450 - £750 | £295 - £495 | Replace valve stem seals via top-end service, no engine removal | Temporary fix, may reduce smoke but ring wear remains |
Intermediate - Piston Ring Service Intermediate | £1,200 - £1,800 | £795 - £1,250 | Remove cylinder head, replace piston rings and seals, reassemble | Addresses root cause but labour-intensive on tight kei engine bay |
Full Replacement - Rebuilt EN07 Engine Best Value | £1,495 - £3,250 | £895 - £2,150 | Supply & fit rebuilt EN07 with upgraded rings, new timing belt, 12-month warranty | Best long-term value, eliminates oil consumption and includes warranty |
On a Subaru R2 worth £1,500-£4,000, a rebuilt EN07 engine with upgraded rings offers better value than repeated top-end repairs. Our specialists include oil consumption fixes as standard on all rebuilt units.
The R2's compact EN07 engines are reliable when maintained, but oil consumption, timing belt risks and supercharger wear can lead to costly repairs. EngineMarket makes it simple to compare prices from trusted UK R2 specialists who understand JDM kei cars. Every rebuilt engine includes upgraded components to address known weaknesses, plus a minimum 12-month unlimited mileage warranty and nationwide delivery.

This section covers all major engine changes across the R2's production timeline, organised so owners can quickly identify their engine and compare rebuilt engine prices from UK specialists.
Subaru R2 engine replacement costs typically range from £895 for a used EN07E to £3,250 for a rebuilt EN07X STi engine, depending on engine code, condition and warranty coverage.
The Subaru R2 exclusively uses EN07 series inline-4 engines: EN07E (46ps SOHC), EN07D (54ps DOHC), EN07X (64ps supercharged STi) and EN07V (46ps variant).
No - Subaru R2 uses the unique EN07 inline-4 engine, not Subaru's boxer architecture. Impreza/Legacy boxer engines are physically incompatible with R2 chassis and mounting points.
A properly reconditioned EN07 engine with upgraded components can last 60,000-100,000+ miles with regular maintenance, matching or exceeding original engine lifespan.
Yes - all engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty, with extended 24-month options available for performance EN07X STi engines.
Engine supply typically takes 1-3 working days for UK stock EN07 units; professional fitting requires 1-2 days at a specialist garage familiar with R2 chassis and EN07 layout.
Used EN07 engines are second-hand units with minimal refurbishment; reconditioned engines are fully stripped and rebuilt with new wear items; rebuilt engines include performance upgrades and extended testing.
We strongly advise against driving an R2 with major engine faults - oil consumption, timing belt issues or supercharger failure can cause catastrophic damage en route. Arrange recovery or collection.
For well-maintained R2s valued over £1,500, engine replacement is often economical versus vehicle replacement - especially with budget EN07 options starting under £900.
The most common EN07 failure causes are oil consumption from piston ring wear, timing belt neglect on interference engines, and supercharger bearing failure on STi models.
