Our Recommendation
Our Recommendation
If your Discovery has a flawless, documented service history with 5,000-mile oil changes, a targeted repair may be viable. However, if there is any cold-start knocking, metal in the oil, or a history of extended service intervals, a full reconditioned replacement with upgraded bearings is the only reliable long-term solution to protect your investment.

Land Rover Discovery TDV6 / SDV6 Engine ReplacementFrequently Asked Questions
Question 1How much does a Land Rover Discovery TDV6 / SDV6 engine replacement cost-
A reconditioned or rebuilt Land Rover Discovery TDV6 / SDV6 engine typically costs between £6,500 and £11,000 for the supply-only unit, depending on the specific engine code (276DT or 306DT) and rebuild specification.
- Rebuilt units include upgraded bearing shells to prevent recurrence.
- Supply and fit packages are available through our premium specialist network.
Question 2What are the signs of crankshaft bearing failure in a Land Rover Discovery TDV6 / SDV6-
Early detection is critical to preventing catastrophic damage to your Land Rover Discovery TDV6 / SDV6 engine.
- Listen for a distinct rhythmic knocking or rumbling noise from the bottom of the engine, especially at cold start.
- Look for low oil pressure warnings, metal flakes in the oil filter, or a sudden loss of power.
Question 3Is it worth replacing the engine in a Land Rover Discovery 4 TDV6 / SDV6-
It depends on the overall condition and specification of the vehicle.
- A typical Discovery 4 is valued between £6,000 and £18,000, meaning a £7,500+ rebuild is a significant investment.
- However, for high-spec SDV6 HSE models in excellent cosmetic condition, a rebuilt engine with a 12-month warranty is often the most cost-effective way to retain a capable, desirable 4x4.
Question 4Can I upgrade my 2.7 TDV6 to a 3.0 SDV6 engine-
While both are V6 diesels, a direct swap is not straightforward.
- The 3.0L 306DT requires different ECU mapping, wiring harnesses, and often upgraded cooling and drivetrain components to handle the increased torque.
- We strongly recommend sticking to a like-for-like replacement to ensure guaranteed compatibility, MOT compliance, and warranty coverage.
Question 5How long does a Land Rover Discovery TDV6 / SDV6 engine supply and fit take-
A straightforward supply and fit replacement for a Land Rover Discovery TDV6 / SDV6 typically takes 3 to 5 days at a premium specialist workshop.
- This allows time for the engine to be delivered, mounted, and thoroughly calibrated and tested.
- Complex cases requiring additional cooling system or drivetrain upgrades may take slightly longer.
