Variant History

Land Rover Defender 110 SVX Engine History & Specs at a Glance

When the SVX (Special Vehicle eXperimental) launched in 1992, it brought premium, expedition-ready features to the iconic long-wheelbase Defender 110. Its engine lineage is rooted in Land Rover's legendary, robust 2.5-litre diesel units, evolving through the classic Tdi era into early electronic diesel management.

1992
200Tdi, 2.5L Diesel, 111hp (Introduction of the SVX special edition, featuring an upgraded interior, roof rack, and the proven, mechanically injected 200Tdi engine).
1994
300Tdi, 2.5L Diesel, 111hp (Update to the 300Tdi engine, featuring improved refinement, the introduction of an EGR system, and the crucial steel locating dowel head gasket upgrade).
1998
TD5 (10P/15P), 2.5L Diesel, 122hp (Later special edition and heritage continuation models adopted the electronic TD5, expanding the SVX legacy into the modern classic era).

Common failure points and repair options

300Tdi Head Gasket Failure

Affected: Land Rover Defender 110 SVX (300Tdi, 1994-1998)
Typical failure mileage: 100,000-150,000+ miles

Root cause

Thermal stress and early plastic locating dowels allowing cylinder head movement, leading to gasket breach and coolant loss.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative (Head gasket + steel dowel upgrade)	£1,500-£2,500	£800-£1,500
Full Replacement - rebuilt/reconditioned engine	£4,500-£6,500	£3,000-£4,500 [ESTIMATED]

Our recommendation

For early head gasket symptoms on a 300Tdi, a specialist repair with the upgraded steel locating dowels is highly effective and cost-efficient. However, if the engine has suffered catastrophic overheating or a seized TD5 ECU, a fully rebuilt unit with all known vulnerabilities addressed is the safest long-term choice for a vehicle of this caliber.

TD5 Injector Loom Oil Leak

Affected: Land Rover Defender 110 SVX (TD5, 1998+)
Typical failure mileage: 80,000-120,000 miles

Root cause

Injector seals fail, allowing engine oil to track along the wiring loom directly into the Engine Control Unit (ECU), causing electrical failure.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative (Loom + seal replacement)	£600-£1,000	£300-£600
Full Replacement - rebuilt/reconditioned engine	£5,000-£7,000	£3,800-£5,500 [ESTIMATED]
