What 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.

Is 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.

Can 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.

How 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.

3 Simple Steps to Finding the Right Replacement Engine

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

Variant History

Land Rover Discovery TDV6 / SDV6 Engine History & Specs at a Glance

The TDV6 and SDV6 badges represent the pinnacle of Land Rover's compact V6 diesel engineering in the Discovery lineup, evolving from the pioneering 2.7-litre unit in the Discovery 3 to the refined, high-torque 3.0-litre powerhouse in the Discovery 4 and 5.

2004
276DT (2720cc), 190hp, launched in the Discovery 3, introducing the compact 60-degree V6 diesel architecture co-developed with PSA.
2009
306DT (2993cc), 211hp (TDV6) / 245hp (SDV6), launched in the Discovery 4, featuring revised internals, an improved oil pump design, and twin-turbo options for the SDV6 badge.
2017
306DT continued in the Discovery 5 (L462), with mild-hybrid (MHEV) variants introduced in later years to meet stricter WLTP emissions standards while maintaining the core V6 architecture.

Common failure points and repair options

Crankshaft Bearing Failure

Affected: Land Rover Discovery TDV6 / SDV6 (306DT, 2009-present)
Typical failure mileage: 80,000-140,000 miles

Root cause

Tin-aluminium coating fatigue on the bearing shells, severely exacerbated by Land Rover's recommended 16,000-mile oil service intervals, leading to oil starvation and spun bearings.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	£2,000-£3,500	£1,500-£2,500
Full Replacement - rebuilt/reconditioned engine	£9,000-£13,000	£7,500-£11,000

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.

Oil Pump Housing Failure

Affected: Land Rover Discovery TDV6 / SDV6 (276DT, 2004-2009)
Typical failure mileage: 80,000-140,000 miles

Root cause

A structural weak point in the oil pump housing at the tensioner mount, which can crack or fail, resulting in sudden and total loss of oil pressure.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	£2,500-£4,000	£1,500-£3,000
Full Replacement - rebuilt/reconditioned engine	£8,000-£11,000	£6,500-£9,500
