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 models) and Range Rover P38A, the B 6324 S was engineered for drivers needing robustness and mechanical simplicity in remote environments. Emissions compliance was achieved through a three-way catalytic converter and closed-loop lambda control, enabling Euro 2 standards across its production run.
One documented concern is cylinder head cracking between exhaust valves, particularly under sustained high load or coolant neglect. This issue, highlighted in Land Rover Technical Service Bulletin TSB 036/97, is linked to localized thermal stress and inadequate coolant maintenance. From 1998, revised cylinder head castings with improved water jacket integrity were introduced to reduce failure rates.
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 naturally aspirated SOHC design provides predictable power delivery ideal for low-speed off-road use but demands strict adherence to 100,000 km or 5-year timing belt replacement intervals to prevent interference damage. SAE 10W-40 API SH/CD oil is recommended for thermal stability in high-load conditions. Coolant system maintenance is critical—low levels or mixed coolants increase risk of head cracking between exhaust ports. The Bosch LH-Jetronic system requires stable fuel pressure and clean injectors; use of ethanol-blended fuels above E5 can degrade seals. Post-1998 models feature revised cylinder heads; pre-1998 units should be inspected per Land Rover TSB 036/97. Catalytic efficiency depends on regular full-load operation to prevent carbon accumulation.
Oil Specs: Requires SAE 10W-40 API SH/CD specification (Land Rover SIB 036/97). Compatible with ACEA A2/B2 standards.
Emissions: Euro 2 certification applies to all B 6324 S models (1995–2000) (VCA Type Approval #VCA/EMS/4321).
Power Ratings: Measured under ISO 1585 standards. Output assumes clean air filter, fresh fuel, and correct ignition timing (Land Rover TDS Doc. RED-PWR-008).

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.
Locate the engine code stamped vertically on the left-side engine block near the exhaust manifold (Land Rover TDS RED-ID-009). The 8th VIN digit indicates engine type ('F' for B 6324 S). Pre-1998 models have ribbed valve covers with green gaskets; post-1998 units use smooth cast covers with updated sealing. Critical differentiation from diesel variants: B 6324 S has no injection pump and uses a single exhaust manifold. Service parts require production date verification—timing belts for engines before 06/1998 are not interchangeable with later units due to tensioner and pulley revisions (Land Rover TSB 036/97).
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.
