How it works

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 Defender 110 300Tdi Engine History & Specs at a Glance

When the 300Tdi launched in the Defender 110 lineup, it represented the pinnacle of classic, mechanically simple diesel reliability before the electronic TD5 era. Its robust 2.5-litre block remained largely unchanged throughout its production run, cementing its legendary status among classic 4x4 enthusiasts.

1994
300Tdi (2495cc), 111hp, launched as the successor to the 200Tdi, featuring improved refinement, better cooling, and a more robust head gasket design.
1998
Production of the 300Tdi in the Defender 110 ceased, replaced by the electronically managed TD5 engine to meet emerging emissions standards.

Common failure points and repair options

Head Gasket Failure

Affected: Land Rover Defender 110 300Tdi (300Tdi, 1994-1998)
Typical failure mileage: 100,000+ miles (often age-related rather than purely mileage-dependent)

Root cause

Original plastic locating dowels can shear under thermal stress, allowing the head gasket to shift and fail, leading to coolant loss and overheating.

Repair options

Repair tier	Dealer price	Specialist price
Head Gasket Replacement (with steel dowel upgrade)	£1,800-£2,500	£1,200-£1,800
Full Replacement - rebuilt/reconditioned engine	£4,500-£6,000	£3,500-£5,000

Our recommendation

If the engine is otherwise healthy, a specialist head gasket repair with steel dowel upgrades is a highly viable and authentic fix. However, if the engine has high mileage, smokes, or lacks compression, a full reconditioned replacement is the most reliable long-term investment for a classic Defender.
