Aston Martin Engine Replacement -Get Quotes from UK Specialists

A rebuilt Aston Martin engine typically costs between £5,500 and £9,500 for the 4.3L or 4.7L V8, rising to £7,500–£12,500 for a reconditioned 5.9L V12 (AM04/AM08). A used, lower‑mileage unit can start from £3,000–£5,000 but carries higher risk. Supply‑and‑fit adds £1,200–£2,000 depending on model complexity. Main dealer pricing for a new V12 engine can exceed £25,000 — which is why most owners choose a specialist‑rebuilt unit.

Four main factors: engine size (V12 costs significantly more than V8), condition grade (rebuilt with upgraded internals vs used as‑is), vehicle age (DB9 and Vantage are straightforward; later DB11 electronics add labour), and supply‑only vs supply‑and‑fit (fitting typically adds £1,200–£2,000). Location also matters — London workshops can charge 20–30% more than Midlands specialists. Our free comparison tool shows transparent, all‑in quotes from vetted Aston Martin engine specialists across the UK.

In most cases, yes — especially if the chassis, gearbox, and bodywork are sound. A specialist‑rebuilt Aston Martin engine with upgraded timing components, brass core plugs, and a new oil pump can outlast the original unit by 50,000+ miles. The alternative — selling the car with a failed engine — often means accepting 50–70% of market value. If your DB9 or V8 Vantage is otherwise well‑maintained and worth £20,000+, replacement makes strong financial sense.

A full supply‑and‑fit package includes: sourcing the correct rebuilt or reconditioned engine (by engine code), removal of the failed unit, installation of the replacement, all new gaskets, seals, fluids and filters, a workmanship warranty (typically 12 months), disposal of the old engine, and a post‑installation road test. Fitting labour usually adds £1,200–£2,000. Always ask whether the quote includes delivery of the replacement engine to the workshop.

For common models like the DB9 or V8 Vantage, a like‑for‑like engine swap typically takes 3–5 working days. More complex models (DB11, DBS Superleggera with twin‑turbo V12) can take 5–7 days due to additional ancillaries and electronic calibration. The biggest variable is engine availability — our network of specialist suppliers stocks commonly replaced codes (AM04, AM08, AJ33, AJ41, M177) for rapid dispatch.

Yes — every reconditioned or rebuilt Aston Martin engine supplied through EngineMarket carries a minimum 12‑month unlimited mileage warranty. Many specialists offer extended 24‑month coverage on rebuilt units with upgraded internal components. Standard warranty covers major internals: cylinder block, crankshaft, pistons, connecting rods, timing chain, oil pump, and cylinder head. Always confirm exact terms — some warranties exclude fitting labour or require an approved workshop for installation.

Used engines are cheaper upfront (£3,000–£5,000) and suit a temporary fix or if you plan to sell the car within 12–18 months. However, you inherit the original failure risks (timing chain wear, core plug corrosion). Reconditioned engines (£5,500–£12,500) include new bearings, piston rings, seals, and upgraded components that address the original design flaws. For a long‑term keeper, reconditioned with a 12‑month+ warranty is almost always better value.

EngineMarket connects you with a UK‑wide network of independent Aston Martin engine specialists — no need to search locally. Known specialist hubs include the Midlands (Cheshire, Derby), London, and Manchester, but we also cover Scotland, Wales, and the South West. Enter your registration or select your model and engine code, and we'll match you with vetted suppliers who stock your specific engine and can offer supply‑only or supply‑and‑fit. Nationwide delivery and collection are available.

The four most common failures that drive replacement demand: timing chain guide embrittlement on AM08 5.9L V12 (DB9, DBS, V12 Vantage — 70k–110k miles), core plug corrosion on AJ‑V8 4.3L and 4.7L engines (V8 Vantage — 60k–90k miles), crankshaft bearing seizure on early AM04 V12s (2004–2008 DB9 — 50k–80k miles), and water pump/turbo coolant line failures on M177 4.0L twin‑turbo V8 (modern Vantage, DB11 V8). Each of these can lead to catastrophic engine failure requiring full replacement rather than repair.

Compare at least three quotes — prices for the same engine code can vary by £1,500+ between suppliers. For tight budgets, a used engine with a short warranty (30–90 days) keeps costs down. For long‑term ownership, invest in a reconditioned unit with upgraded components (brass core plugs, uprated oil pump, revised timing guides). Ask each supplier whether fitting, delivery, and VAT are included in the quoted price. Supply‑only can save £500–£1,000 if you have a trusted independent garage for installation.
