The Land Rover B 6324 S is a 2,435 cc, inline — four petrol engine produced between 1995 and 2000. It was developed from the Volvo Redblock B6304/B6324 series, featuring a cast — iron block, aluminium head, and single overhead camshaft (SOHC) with 8 valves. In standard tune it delivered 110 kW (150 PS) and 220 Nm of torque, providing dependable mid — range power for light off — road and rural applications.
Fitted primarily to the Land Rover Discovery Series I (300 Tdi replacement…
Production years 1995–2000 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/4321).
The Land Rover B 6324 S is a 2,435 cc inline-four petrol engine engineered for utility-focused SUVs (1995–2000). It combines a durable iron block with a SOHC valvetrain to deliver consistent performance in rugged conditions. Designed to meet Euro 2 emissions standards, it prioritizes mechanical reliability over high specific output.

The Land Rover B 6324 S was used across Land Rover's L319/P38A platforms with longitudinal mounting and derived from Volvo's Redblock series. This engine received platform-specific adaptations-shorter accessory drives in the Discovery and upgraded ignition systems in the Range Rover-and from 1998 the P38A adopted revised cylinder head castings, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The B 6324 S's primary reliability risk is cylinder head cracking on early builds, with elevated incidence in high-load or poorly maintained cooling systems. Internal Land Rover quality reports from 1998 noted a significant share of pre-1998 engines requiring head replacement before 150,000 km, while UK DVSA records show increased catalytic converter failures in vehicles with lean-running conditions. Extended idling and delayed maintenance increase thermal stress, making coolant and belt service adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The B 6324 S is mechanically simple and robust when maintained, but early models (1995–1997) had reliability concerns, particularly cylinder head cracking. Later revisions (post-1998) improved head durability, so well-maintained examples can be dependable. Regular servicing and using correct coolant and oil (10W-40) greatly aid longevity.
The biggest issues are cylinder head cracking (especially between exhaust valves), timing belt failure if not replaced on schedule, and fuel injector clogging from low-quality petrol. Other complaints include oil leaks from gaskets and occasional ignition coil faults. These are well-documented in Land Rover service bulletins.
This 2.4L inline-four petrol was used in the Land Rover Discovery Series I (1995–2000) as the base petrol option and in the early Range Rover P38A (1995–2000) before full V8 adoption. All applications met Euro 2 emissions standards. It was phased out in favour of the 4.0L V8 and later Ford-derived units.
Limited tuning potential. The SOHC 8-valve design restricts high-RPM airflow, but ECU remapping and exhaust upgrades can yield modest gains (~10–15 kW). Carburettor conversion kits exist but reduce reliability. Most owners prioritise durability over performance, making significant tuning uncommon.
Moderate to poor. In a Discovery Series I, typical consumption is ~14.5 L/100km (city) and ~10.0 L/100km (highway), or about 24 mpg UK combined. Real-world figures vary significantly with terrain and load, but expect 18–24 mpg (UK) on mixed roads for a healthy B 6324 S.
Yes. The B 6324 S is an interference engine. If the timing belt fails, pistons will contact open valves, causing severe internal damage. That's why belt replacement every 100,000 km or 5 years is critical—any missed service window should be addressed immediately.
Land Rover specifies SAE 10W-40 API SH/CD mineral or semi-synthetic oil. Always use a quality oil suitable for older petrol engines and change it every 15,000 km or annually to ensure valve train protection and minimise deposit formation.
