Common Problems
Rolls Royce Phantom Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Rolls Royce Phantom's V12 engines-N73B68 naturally aspirated and N74B66/N74B68 twin-turbo-are engineered for refinement but face specific failure patterns driving replacement enquiries. Timing chain guide wear on N73 units and turbo wastegate fatigue on N74 engines dominate UK search volume. Every rebuilt engine supplied through EngineMarket includes...

Most affected vehicles
Rolls Royce Phantom VII Standard/Extended WheelbaseDrophead Coupé
Rolls Royce Phantom VII Standard/Extended Wheelbase, Drophead Coupé, Coupé (2003-2017, N73B68, N73B68A, N73B68B)
Failure mileage range
70,000-100,000 miles
Typical failure window
Root cause
Plastic timing chain guides degrade from heat cycling and oil contamination, causing chain slack, rattle, and eventual jump.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Guide Replacement - Replace guides/tensioner before failure | £8,500 - £12,000 | £5,200 - £7,800 | Remove front cover, replace plastic guides and hydraulic tensioner with updated parts | Viable only if caught early; prevents catastrophic valve damage but labour-intensive |
| Full Replacement - Rebuilt N73B68 Engine - Supply & fit rebuilt unit with upgraded components | £28,000 - £35,000 | £18,500 - £24,000 | Remove failed engine, install rebuilt N73B68 with metal-reinforced guides, bench-tested, 12-month warranty | Recommended once rattle is audible; addresses root cause and restores factory refinement |
Our recommendation
On a Phantom VII worth £80,000-£150,000, preventative timing chain service at 60k miles offers better value than waiting for failure. If rattle is present, replacement with a rebuilt engine including upgraded guides is the only reliable long-term solution.
