The Renault F3P 764 is a 1,721 cc, inline‑four naturally aspirated petrol engine produced between 1990 and 1996. It features a cast iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) with two valves per cylinder. Output typically ranged from 79 kW (107 PS), with torque figures around 145 Nm, making it the higher-output variant within the F3P family.
Fitted primarily to performance-oriented variants like the Clio 16S and Laguna I GT, the F3P 764 was engineered for spirited driving and enhanced mid-range response. It was commonly found in models where a balance of cost, reliability, and increased power over the base F3P 708 was desired. Emissions compliance for its era was managed through basic engine management and exhaust catalyst systems.
One documented concern, shared with the broader F3P series, is premature wear of the camshaft and rocker arms, particularly in high-mileage examples. This issue, referenced in Renault Technical Note MEC 012/94, is often attributed to the design of the rocker arm pivot points and oil flow characteristics. The engine was eventually superseded by more efficient multi-valve designs.
Production years 1990–1996 meet pre-Euro or Euro 1 standards depending on specific model and market (VCA UK Type Approval data for reference models).
The Renault F3P 764 is a 1,721 cc inline‑four naturally aspirated petrol engine engineered for compact performance models (1990-1996). It combines a robust cast iron block with a SOHC 8-valve cylinder head to deliver enhanced power for its era and straightforward mechanical reliability. Designed for the pre-Euro and early Euro 1 era, it prioritizes simplicity and serviceability.

The SOHC 8-valve design offers mechanical simplicity and ease of repair but delivers modest peak power compared to contemporary multi-valve engines. Regular oil changes with the correct viscosity (10W-40/15W-40) are critical to prevent accelerated camshaft and rocker arm wear, a known issue documented in Renault Technical Note MEC 012/94. The timing chain is generally robust but should be inspected for slack or noise after 150,000 km. Fuel injectors and ignition components (distributor, HT leads) are common service items on high-mileage examples.
Oil Specs: Requires mineral or semi-synthetic oil meeting ACEA A2/B2 or equivalent (Renault Service Manual 77 11 061 764).
Emissions: Euro 1 certification applies to specific late-production models only (VCA Type Approval Database). Most units are pre-Euro.
Power Ratings: Measured under EEC 80/1269 standards. Output is specific to the 764 variant (Renault Group PT-1995).

The Renault F3P 764 was used across Renault's Clio and Laguna platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU and accessory bracket variations between the Clio and Laguna-but no major facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the gearbox flange (Renault Service Manual 77 11 061 764). The code will read "F3P 764" followed by a serial number. Visually, it can be identified by its SOHC 8-valve head, distributor-based ignition system, and lack of a turbocharger. Critical differentiation from the F3P 708: The 764 is specifically the 107 PS variant; consult the EPC or engine stamp for definitive identification.
The F3P 764's primary reliability risk is camshaft and rocker arm wear, with elevated incidence in high-mileage or poorly maintained engines. Renault Technical Note MEC 012/94 documents this issue, noting it can lead to noisy valve train operation and reduced performance. Infrequent oil changes and use of incorrect oil viscosity make adherence to service schedules critical.
