Land Rover Discovery Replacement Engines
The Discovery 3 (2004–2009) and Discovery 4 (2009–2016) are built around the 2.7 and 3.0 V6 diesels — the 276DT and 306DT — while the Discovery 5 moved to the 3.0 diesel and supercharged petrol. The TDV6 bottom end is our most-requested rebuild. Every engine is fully tested and carries a 12-month / 12,000-mile parts-and-labour warranty.

Common Land Rover Discovery Engine Failures
TDV6 crankshaft failure
The signature Discovery fault: crank and bearing wear on the 276DT and 306DT, often with little warning beyond a knock or oil-pressure light. Stop driving immediately.
Read the symptoms guide →Turbo & oil feed problems
Restricted oil feeds starve the turbos; whining, smoke or oil use are the early signs.
Book diagnostics →EGR cooler failure
Coolant loss or limp mode can trace to the EGR cooler — sometimes misdiagnosed as head-gasket trouble.

Land Rover Discovery Questions
How much is a replacement Discovery engine?
Reconditioned TDV6 engines start from £2,500–£5,000, with supply and fit from £2,500–£5,000. Enter your reg for a fixed written quote.
My Discovery 4 is knocking — can it be saved?
Sometimes, if caught early. If the crank has let go at speed, replacement is usually the economic answer. Either way, stop driving it — running a knocking TDV6 turns a repairable engine into scrap.
Do you upgrade the known TDV6 weak points?
Yes — our reconditioned units use an uprated bearing specification and a new oil pump as standard.
Discovery 3 or 4 — do you cover both?
Yes, plus the Discovery 5. Give us your reg and we'll confirm the exact engine variant.
