Production Years: 1999 - 2011
Engine: EJ251 / EJ252 / EJ253 / EJ254
Typical failure window
The original multi-layer steel (MLS) head gasket design on early EJ25 engines was prone to external coolant leaks due to uneven cylinder head clamping pressure and thermal cycling. Over time, coolant seeps into the combustion chamber or oil galleries, leading to overheating or oil contamination.
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
| Minor - Preventative Gasket Refresh Minor | £1,800 - £2,800 | £950 - £1,600 | | Replace both head gaskets with upgraded MLS units, resurface cylinder heads, replace timing components and coolant system parts. | Only viable if caught early with no overheating damage. Adds 40,000-60,000 miles if cooling system is maintained. | |
| Intermediate - Short Block Repair Intermediate | £3,200 - £4,800 | £1,900 - £3,100 | | Replace damaged pistons/rings if coolant entered cylinders, machine heads, install upgraded gaskets, full fluid flush. | Appropriate when minor hydrolock occurred but block is undamaged. | Not suitable if crank or bearings are scored. |
| Full Replacement - Rebuilt EJ25 Engine Best Value | £5,500 - £8,200 | £2,800 - £4,500 | | Supply & fit of reconditioned EJ25 with upgraded head gaskets, pistons, and bearings; bench-tested; 12-month unlimited mileage warranty. | Best value for high-mileage vehicles or when block damage is confirmed. Restores reliability with modern component upgrades. |
If your EJ25 is showing early coolant seepage but hasn't overheated, a specialist preventative gasket refresh offers the best value. However, once overheating has occurred or oil is contaminated, the risk of hidden damage makes a full rebuilt engine the more reliable long-term investment - especially on Foresters and Outbacks still worth £3,000-£7,000.
Every problem group above shares a common truth: Subaru engines are repairable, but the right solution depends on catching the issue early and choosing a specialist who understands Boxer engineering. EngineMarket makes it simple to compare prices from trusted UK Subaru specialists - all offering supply & fit, upgraded components that address the original failure point, and a minimum 12-month unlimited mileage warranty. With nationwide delivery and transparent quotes, you can get back on the road without paying the main dealer premium.

Subaru's only diesel offering for the UK market, the 2.0L EE20 boxer diesel powered Forester, Outback, Legacy and XV models from 2008-2016. While offering strong torque and AWD capability, this engine family is defined by a critical weakness: crankshaft failure under sustained load, which is terminal and drives the majority of replacement demand for Subaru diesel owners

Hybrid and electric vehicles may require specialist safety training. Always ensure the quote includes labour and safety checks.
High-output models command a premium due to specialist components, lower supply volumes and more complex fitting.
Diesel can suit motorway mileage, petrol often suits shorter trips, and hybrid or electric value depends on charging habits.

Subaru's diesel engine range in the UK is limited to the EE20 2.0-litre boxer diesel, fitted to the Outback, Legacy, and Forester from 2008 to 2015\. While offering good fuel economy and Subaru's trademark all-wheel drive, these engines have proven problematic with DPF, EGR, and turbocharger failures.

This section maps every major engine change across the Subaru model range - from the EJ20 and EJ25 Boxer era of the Impreza, Forester and Legacy through the FA20DIT turbo of the WRX, the FB-series naturally aspirated replacements, the e-Boxer hybrid, and the Solterra's all-electric drivetrain - so owners can identify the exact engine fitted to their Subaru by year and compare rebuilt engine prices from UK specialists.
A reconditioned Subaru engine typically costs £2,200-£4,800 depending on code (EJ25, FB25, FA20), with performance rebuilds (EJ257, FA20F) ranging £3,800-£7,500. Supply-only fitting adds £600-£1,500 labour, while main dealers charge 40-60% more. For budget options, used engines start around £800 but carry higher risk. *Always compare three quotes before committing - prices vary significantly by supplier and engine condition.*
Compare Subaru engine replacement prices nowFour key factors drive pricing: engine code (EJ25 vs EJ257), condition (used vs reconditioned vs rebuilt), vehicle complexity (STI or H6 models cost more), and supply-only vs supply-and-fit. Location matters too - London and Southeast labour rates run 20-30% higher. Our comparison tool shows transparent, itemised quotes so you see exactly what you're paying for.
Get quotes from UK Subaru engine specialistsIn most cases, yes - especially if the chassis, gearbox and AWD system are solid. A rebuilt Subaru engine with upgraded components (e.g., MLS head gaskets on EJ25, uprated crank on EE20) often outlasts the original. If your Forester or Outback holds £3,000-£8,000 value, replacement is almost always more economical than buying another vehicle.
Find reconditioned Subaru engines with comprehensive warranty coverSupply-and-fit covers sourcing your exact engine code, removing the old unit, installing the replacement with new fluids/filters, workmanship warranty, safe disposal of the old engine, and a post-fit test-drive. Labour typically adds £600-£1,500 depending on model complexity. *Always confirm whether VAT, delivery and ECU reset are included in your quote.*
Compare Subaru engine supply and fit dealsCommon models like Forester or Impreza with EJ25/FB25 engines typically take 3-5 working days for a like-for-like swap. Complex builds (STI EJ257, H6 EZ36, e-BOXER hybrids) may require 5-7 days. The biggest variable is engine availability - our network stocks commonly replaced codes to minimise wait times. *Ask suppliers about current lead times before booking.*
Use our free comparison tool to see whether a rebuilt or used Subaru engine makes financial senseYes - every reconditioned Subaru engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty. Extended 24-month coverage is often available on fully rebuilt or remanufactured units. Warranty covers major internals: crankshaft, pistons, timing components, oil pump and cylinder heads. *Always confirm exact terms directly with your chosen supplier before purchase.*
Find Subaru engines with 12-month unlimited warrantyUsed engines (£800-£2,500) offer lower upfront cost and suit temporary fixes or imminent resale. Reconditioned units (£2,200-£4,800) include new gaskets, bearings and seals, plus warranty protection and should deliver another 100k+ miles. For failure-prone engines like EJ25 (head gasket) or EE20 (crankshaft), a reconditioned unit with upgraded components is strongly recommended for long-term reliability.
Compare used vs reconditioned Subaru engine pricesEngineMarket connects you with a UK-wide network of vetted Subaru specialists, including recognised hubs in the Midlands, Northwest and Southeast. Our registration lookup instantly matches you with nearby suppliers who stock your specific engine code and offer fitting. Nationwide delivery is available if no local specialist holds your required unit.
Find Subaru engine specialists near me with live stockThe four most catastrophic failures driving replacement are: EJ25 head gasket failure (1999-2011 NA 2.5L Forester/Outback), EE20 boxer diesel crankshaft fracture (2008-2016), EJ257 piston ringland/rod bearing failure (STI turbo), and FA20 valve spring recall/timing tensioner wear (BRZ/WRX). Early detection rarely prevents these from becoming terminal - replacement is usually the most reliable solution.
Get quotes for engines addressing these common Subaru failuresCompare multiple quotes - prices for the same EJ25 or FB25 code can vary by £1,000+ across suppliers. Consider used for tight budgets, but choose reconditioned with upgraded parts for long-term ownership. Ask about supply-only if you have a trusted garage, and always verify whether fitting, delivery and VAT are included. *Our free comparison tool does the legwork so you don't miss hidden savings.*
