The Land Rover M62 B44 is a 4,398 cc, V8 petrol engine produced between 1997 and 2002. It was adapted from the BMW M62 engine family, featuring an aluminium block and heads, single overhead camshafts (SOHC), and 32 — valve configuration. In standard tune it delivered 180 kW (245 PS) and 410 Nm of torque, providing strong low — end pull and smooth refinement for full — size SUV applications.

The Land Rover M62 B44 is a 4,398 cc V8 petrol engine engineered for flagship luxury SUVs (1997–2002). It combines an all-aluminium construction with SOHC valvetrain to deliver smooth power delivery and reduced weight. Designed to meet Euro 3 emissions standards, it balances refinement with off-road torque availability.

The Land Rover M62 B44 was used exclusively in the Land Rover P38A platform with longitudinal mounting and derived from BMW's M62 architecture. This engine received platform-specific adaptations-upgraded engine mounts and revised ECU calibration for off-road torque delivery-and from 2000 the P38A adopted reinforced intake manifold flaps, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M62 B44 is mechanically refined and smooth-running, but early models (1997–1999) had reliability concerns, particularly intake swirl flap failure. Later revisions (post-2000) improved flap durability, so well-maintained examples can be dependable. Regular servicing and using correct oil (10W-60) greatly aid longevity.
The biggest issues are intake swirl flap failure (leading to rattle or engine damage), timing chain wear if not inspected on schedule, and fuel injector coking from low-quality petrol. Other complaints include oil leaks from gaskets and occasional ECU or sensor faults. These are well-documented in Land Rover service bulletins.
This 4.4L V8 petrol was used exclusively in the Land Rover Range Rover P38A (1997–2002) as the top-tier petrol option before being replaced by the 4.6 HSE V8. All applications met Euro 3 emissions standards. It was a short-lived but significant model due to its BMW-sourced engineering and smooth performance.
Limited tuning potential. The SOHC 32-valve design restricts high-RPM airflow, but ECU remapping and exhaust upgrades can yield modest gains (~15–25 kW). Forced induction kits exist but require extensive modifications. Most owners prioritise reliability and refinement, making significant tuning uncommon.
Moderate to poor. In a Range Rover P38A 4.4 V8i, typical consumption is ~16.5 L/100km (city) and ~11.0 L/100km (highway), or about 21 mpg UK combined. Real-world figures vary significantly with load and terrain, but expect 17–21 mpg (UK) on mixed roads for a healthy M62 B44.
Yes. The M62 B44 is an interference engine. If the timing chain fails, pistons will contact open valves, causing severe internal damage. That's why chain inspection every 120,000 km is critical—any rattling at startup should be investigated immediately.
Land Rover specifies SAE 10W-60 API SL mineral or semi-synthetic oil. Always use a quality oil suitable for high-performance V8 engines and change it every 15,000 km or annually to ensure valve train protection and minimise deposit formation.
