The Renault F4R 796 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 2001 and 2008. It features a dual overhead camshaft (DOHC) design with 16 valves and multipoint fuel injection. This architecture delivers a balance of power and refinement, with outputs typically around 100 kW (136 PS) and 190 Nm of torque.
Fitted to models such as the Laguna II and Espace III, the F4R 796 was engineered for smooth, reliable performance in mid-size family vehicles. Its character prioritises linear power delivery and everyday drivability over outright sportiness. Emissions compliance for its production period was met through precise engine management and catalytic converter technology.
One documented concern involves premature wear of the exhaust camshaft lobes, potentially leading to reduced performance and misfires. This issue, referenced in Renault technical documentation, is often attributed to specific lubrication characteristics under certain operating conditions. Later production runs incorporated revised camshaft metallurgy to address this.
Production years 2001–2005 meet Euro 3 standards; 2006–2008 models meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5679).
The Renault F4R 796 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for mid‑size sedans and MPVs (2001-2008). It combines DOHC 16-valve architecture with multipoint fuel injection to deliver smooth, linear power delivery and reliable everyday performance. Designed to meet Euro 3 and Euro 4 standards, it balances refinement with practical economy.

The naturally aspirated design offers predictable throttle response but requires adherence to 15,000 km oil change intervals using specified Renault RN0700/RN0710 oil to protect against camshaft wear. The timing chain is generally robust but should be inspected for tensioner wear around 150,000 km. Valve clearance checks are recommended every 60,000 km as per Renault service schedules. The MPI system is reliable but fuel injectors may require cleaning if poor fuel quality is used consistently. Pre-2004 engines should be monitored for exhaust cam lobe wear.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Owner's Manual Supp. 2004). ACEA A3/B4 is the underlying standard.
Emissions: Euro 3 certification applies to 2001-2005 models; Euro 4 for 2006-2008 (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model years (Renault TIS Doc. F4R-006).

The Renault F4R 796 was used across Renault's Laguna II and Espace III platforms with transverse mounting. This engine received platform-specific adaptations-including different engine mounts and accessory layouts-and from 2006 received minor ECU updates for Euro 4 compliance, though core mechanicals remained unchanged. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, near the gearbox flange (Renault TIS F4R-004). The code will read "F4R 796". Visually, it features a black plastic cam cover with "16V" and "2.0" markings. Differentiate from the F4R 770 by its specific ECU mapping and power output. Service parts for pre-2004 and post-2004 engines may differ for camshafts and related components due to the wear issue update.
The F4R 796's primary reliability risk is premature exhaust camshaft lobe wear, particularly in early production (pre-2004). Renault internal service data indicated a notable incidence rate requiring camshaft replacement before 100,000 km in affected units. Extended oil change intervals or use of incorrect oil specification can exacerbate this wear, making adherence to service schedules critical.
