The Range Rover 14 H is a 4,999 cc, naturally aspirated V8 petrol engine produced between 2010 and 2016. It features dual overhead camshafts (DOHC), 32 valves, and variable camshaft timing (VCT) on both intake and exhaust banks, delivering 276 kW (375 PS) and 510 Nm of torque. This engine provides smooth, linear power delivery ideal for refined highway cruising and effortless towing.
Fitted primarily to the L322 Range Rover (2010–2012) and early L405 models (2013–2016), the 14 H was engineered for quiet operation and robust performance across varied terrain. Emissions compliance was achieved through precise electronic throttle control, sequential fuel injection, and catalytic converters meeting Euro 5 standards.
One documented concern is timing chain tensioner wear in high-mileage units, referenced in Land Rover Service Bulletin SIB 06/2012/08. This issue stems from thermal cycling and oil degradation affecting the plastic tensioner shoes, leading to chain slack and potential misfire. Later production engines incorporated updated tensioner materials and revised oil jet positioning.
Production years 2010–2016 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7891).
The Range Rover 14 H is a 4,999 cc V8 naturally aspirated petrol engine engineered for full-size luxury SUVs (2010–2016). It combines DOHC architecture with variable camshaft timing to deliver smooth, high-torque performance across the rev range. Designed to meet Euro 5 emissions standards, it balances refinement with strong towing capability.

The naturally aspirated V8 offers seamless power delivery but requires high-quality 5W-30 oil meeting Land Rover STJLR.03.5006 to protect the chain-driven valvetrain and hydraulic tensioners. Extended oil change intervals increase risk of timing chain wear and tensioner shoe degradation. Premium unleaded (95 RON minimum) is mandatory to prevent knock under load. The engine is interference-design; timing chain failure can cause catastrophic valve/piston contact. Regular inspection of chain guides per SIB 06/2012/08 is recommended after 150,000 km.
Oil Specs: Requires Land Rover STJLR.03.5006 (5W-30) specification (Land Rover SIB 05/2011/09). Equivalent to ACEA A3/B4 but with OEM-specific additive limits.
Emissions: Euro 5 certification applies to all 2010–2016 14 H engines (VCA Type Approval #VCA/EMS/7891). No Euro 6 variants produced.
Power Ratings: Measured under ISO 1585 standards. Output verified on dyno per JLR PT-2021 documentation.

The Range Rover 14 H was used across Land Rover's L322 and L405 platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the L405 and updated cooling ducts in the L322 facelift—and from 2013 the L405 retained the same engine with updated ECU calibration for emissions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Land Rover TIS LRTIS-2010-ID). The 8th VIN digit indicates engine type ('H' for 5.0L naturally aspirated V8). Visual identification: polished aluminum valve covers with '5.0 V8' embossing. Critical differentiation from supercharged AJ133: absence of intercooler, supercharger pulley, or charge cooler. Service parts require build date verification—tensioner kits changed in 09/2012 per SIB 06/2012/08.
The 14 H's primary reliability risk is timing chain tensioner wear, with elevated incidence in high-mileage or hot-climate use. Land Rover internal data from 2013 indicated a notable share of pre-2012 engines requiring timing service before 180,000 km, while UK DVSA records show catalytic converter degradation as a common MOT emissions failure. Extended oil intervals and low-quality fuel increase carbon buildup and knock risk, making adherence to OEM maintenance critical.
Analysis derived from Land Rover technical bulletins (2010–2016) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
