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), t…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 14 H offers smooth, refined performance but has known issues with timing chain tensioners and catalytic converters. Early engines (pre-2012) are more prone to timing wear. With strict adherence to oil changes (every 15,000 km) and use of 5W-30 STJLR.03.5006 oil, well-maintained examples can exceed 250,000 km reliably.
Top issues include timing chain tensioner wear, catalytic converter degradation, valve cover oil leaks, and variable cam timing solenoid faults. These are documented in Land Rover SIBs 06/2012/08 and 05/2011/09, and commonly appear in high-mileage or poorly maintained vehicles.
The 14 H powered the Range Rover L322 (2010–2012) and L405 (2013–2016) as the 5.0 V8. It was exclusive to these models and not used by other manufacturers. All units meet Euro 5 emissions standards.
Limited potential. As a naturally aspirated engine, gains are modest—typically +15–25 kW via ECU remap and intake/exhaust upgrades. The engine responds well to breathing improvements, but lacks the forced-induction headroom of supercharged variants. Aggressive tuning may reduce longevity without internal upgrades.
Real-world consumption is ~16.8 L/100km (city) and ~11.5 L/100km (highway), or about 17 mpg UK combined. Expect 15–19 mpg (UK) depending on driving style and vehicle load. Premium 95 RON fuel is required for optimal performance and knock prevention.
Yes. The 14 H is an interference engine. If the timing chain fails or jumps, pistons can collide with open valves, causing severe internal damage. Regular inspection of chain tensioners and guides is essential to prevent catastrophic failure.
Land Rover specifies SAE 5W-30 synthetic oil meeting STJLR.03.5006. This formulation ensures proper lubrication of the timing components and VCT system. Oil should be changed every 15,000 km or annually, whichever comes first.
