Aston Martin One-77 Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Aston Martin One-77's exclusive Cosworth-developed AM11 7.3L V12 is engineered for hypercar performance, but like all high-revving naturally aspirated units, it has documented failure points that drive replacement enquiries. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure...

Failure mileage range
8,000-15,000 miles on track-focused examples
Typical failure window
Root cause
Front-mid engine layout combined with extreme lateral G-forces can cause momentary oil pickup starvation in the dry-sump system under sustained cornering.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Oil System Upgrade | £8,000 - £15,000 | £5,000 - £10,000 | Enhanced scavenge pump inspection, oil baffle upgrade, system flush with Cosworth-approved fluids | Suitable for road use; reduces surge risk but does not eliminate under extreme track conditions |
| Full Replacement - Rebuilt / Reconditioned AM11 Engine | £75,000 - £120,000 | £45,000 - £85,000 | Complete engine rebuild with upgraded oil control components, bench testing, Cosworth-certified calibration, 12-month warranty | Recommended for appreciating assets; addresses root cause and preserves collector value with provenance documentation |
Our recommendation
On a One-77 valued at £1.2m-£2m+, preventative oil system upgrades offer strong value for road-focused owners. For track enthusiasts or collectors preserving investment-grade provenance, a Cosworth-certified rebuilt engine with enhanced oil control is the definitive solution.
