Common Problems
Rolls Royce Phantom VII Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Rolls Royce Phantom VII's N73B68 6.75L V12 is a sophisticated engine requiring specialist care. Double VANOS failure, timing chain stretch and Valvetronic issues dominate replacement enquiries. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure point - plus a minimum 12-month...

Double VANOS Failure
Most affected vehicles
Rolls Royce Phantom VII PhantomPhantom EWB
Rolls Royce Phantom VII Phantom, Phantom EWB, Drophead Coupe, Coupe (2003-2017, N73B68/A/B/C)
Failure mileage range
80,000-150,000 miles
Typical failure window
Root cause
Variable valve timing solenoids and actuators wear from oil contamination and heat cycling, causing camshaft timing errors.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - VANOS Solenoid Replacement | £2,500 - £4,000 | £1,200 - £2,200 | Replace faulty solenoids and seals, reset adaptation values | Viable if caught early before actuator damage; 20,000-40,000 mile extension |
| Intermediate - VANOS Actuator Rebuild | £6,000 - £9,500 | £3,500 - £5,500 | Remove cylinder heads, rebuild or replace VANOS units, update software | Addresses root cause; suitable for engines under 120,000 miles with good compression |
| Full Replacement - Rebuilt N73B68 Engine | £25,000 - £35,000 | £14,000 - £20,000 | Supply & fit fully reconditioned N73 with upgraded VANOS components, 12-month warranty | Best value for high-mileage engines or when bottom-end wear is present |
Our recommendation
On a Phantom VII valued at £35,000-£70,000, a £14,000-£20,000 rebuilt engine with warranty often represents better long-term value than repeated VANOS repairs, especially if the engine has exceeded 120,000 miles.
