Land Rover 4.4 Engines Rebuild, Repair & Replacement

The Land Rover 4.4 TDV8 engine — used in the Discovery 4 and shared with the Range Rover platform — is a complex twin-turbocharged V8 diesel that needs platform-specific knowledge to diagnose and repair correctly. Timing chain failures, turbocharger faults and oil pressure problems are frequently misdiagnosed or incompletely repaired by non-specialist workshops, leading to repeat failures. At Vogue Technics, we work on the 4.4 TDV8 regularly across both Land Rover and Range Rover applications and understand exactly where these engines fail.

When a Discovery 4 4.4 TDV8 develops a fault, the correct repair route depends on a full strip-and-inspect assessment. A timing chain replacement with oil-feed system checks is one of the most common jobs on this engine. Where internal damage is more extensive — bearing wear, cylinder damage or oil starvation — a full measured rebuild is often the most cost-effective long-term solution. We do not quote before inspecting: the figure you receive reflects actual condition, not an estimate.

All Land Rover 4.4 TDV8 engine work at Vogue Technics uses OEM or quality-matched components. Timing chain kits, turbo units and oil-feed lines are chosen specifically for this engine. Every major job is road-tested, oil-pressure checked and system-verified before the vehicle is returned. Written warranty terms are confirmed before work starts.

When a Land Rover 4.4 TDV8 engine has suffered severe internal damage — from oil starvation, timing failure or catastrophic turbo failure causing secondary damage — replacement with a quality-checked used or reconditioned unit is often the most practical route. Vogue Technics source 4.4 V8 replacement engines confirmed to the correct engine code and specification for your vehicle registration.

A used Land Rover 4.4 TDV8 engine is suitable where the original has suffered terminal mechanical failure and cost is the primary concern. A reconditioned unit provides significantly greater confidence — stripped, measured and rebuilt with new seals, bearings, timing components and turbo oil-feed lines — and is recommended for Discovery 4 owners who want long-term reliability from the replacement unit.

All replacement engines supplied by Vogue Technics include written warranty terms. We manage the full supply-and-fit process including post-installation road testing and oil system checks, or supply-only for owners with a preferred installer. UK-wide vehicle collection is available for all Land Rover 4.4 engine work.
