Land Rover's rugged engineering is celebrated off-road, but specific engine families dominate the UK replacement market due to predictable design weaknesses. The TDV6 V6 diesel, 5.0L V8 petrol, and 2.0L/2.2L TD4 units account for the highest volume of specialist enquiries we handle.

Crankshaft & Bearing Failure
Most affected vehicles
Land Rover Range Rover Sport L320/L494, Discovery 4, Defender L663 (2009-2018, 2.7L & 3.0L TDV6/SDV6)
Failure mileage range
60,000-100,000 miles
Typical failure window
Root cause
The original main bearings lack sufficient clearance under sustained high-load off-road driving, leading to premature wear and oil starvation. This causes crankshaft flex, spun bearings, and often catastrophic block damage without clear warning.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Diagnostic only - oil system flush & inspection | £600 - £900 | £350 - £550 | Engine oil and filter change, oil pressure sensor testing, sump removal and metallic debris inspection. | Only viable at the very first rattle; does not stop progression once bearing damage starts. |
| Intermediate - crankshaft reground & uprated bearings | £4,500 - £6,800 | £2,400 - £3,800 | Engine strip-down, crankshaft machining, oversized or uprated bearings, and oil pump replacement. | Higher recurrence risk if crankshaft flex has already caused micro-fractures. |
| Full replacement - rebuilt TDV6 with forged crankshaft | £7,500 - £10,500 | £3,900 - £5,200 | Supply and fit complete rebuilt engine with reinforced crankshaft, uprated oil pump, upgraded bearings, and bench testing. | Most reliable long-term route and the one that removes the core design weakness. |
Our recommendation
On a TDV6 Land Rover, once you hear the characteristic deep knocking from the sump, the crankshaft has already compromised. A minor flush or standard reground rarely survives more than 10k-15k miles. We strongly recommend a fully rebuilt unit with a reinforced crankshaft and uprated oil pump to prevent repeat failure and protect the vehicle's resale value.

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