Clear information first, then the right engine and specialist for your exact vehicle.

Variant History

Range Rover TD6 Engine History & Specs at a Glance

Common failure points and repair options

Crankshaft Bearing & Oil Pump Failure

Affected: Range Rover TD6 (306DT, 2015-2021)
Typical failure mileage: 80,000-140,000 miles

Root cause

The tin-aluminium coating on the crankshaft bearings can fatigue under high load or poor oil maintenance, while the oil pump can suffer from premature wear, leading to catastrophic bottom-end failure.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative (Oil pump replacement + bearing inspection)	£2,500-£4,000	£1,500-£2,500
Full Replacement - rebuilt/reconditioned engine	£11,000-£15,000	£7,500-£11,000 [EM-QUOTE]

Our recommendation

If the issue is strictly early-stage oil pressure fluctuation, a specialist oil pump replacement and thorough inspection is the most cost-effective fix. However, if there is accompanying engine knock, loss of compression, or internal damage, a fully rebuilt unit with all known vulnerabilities addressed is the safest long-term choice for a vehicle of this caliber.
