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.

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 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.
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.
Analysis derived from Renault technical bulletins (1990-1996) and UK DVSA failure statistics (historical data). 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 F3P 764 is generally robust if well-maintained. Its main weakness is camshaft/rocker wear, prevalent in high-mileage or neglected engines. Regular oil changes with the correct specification are crucial. With proper care, these engines can easily exceed 200,000 km.
The most frequent issues are camshaft and rocker arm wear, timing chain tensioner failure, and distributor/ignition component wear. Coolant leaks from hoses and the thermostat housing are also common on aged examples. These are documented in Renault service manuals.
The F3P 764 was primarily used in the performance variants of the first-generation Renault Clio (Clio 16S) and first-generation Laguna (Laguna 1.8 GT) between 1991 and 1996. It was the higher-output 107 PS version of the F3P engine family.
Yes, but gains are modest due to the 8-valve head. Common upgrades include a performance exhaust, air filter, and ECU remap, yielding 10-15 kW extra. More significant power requires head work or a swap to a 16-valve engine, which is a popular modification for the Clio 16S platform.
Real-world fuel economy is moderate. Expect around 9.0–10.0 L/100km (28–31 mpg UK) in mixed driving for a Clio 16S, and 10.0–11.5 L/100km (25–28 mpg UK) for the heavier Laguna GT, depending on driving style and condition.
Yes. The F3P 764 is an interference engine. If the timing chain fails or jumps, the pistons can collide with the open valves, causing significant internal engine damage. Regular inspection of the timing chain and tensioner is essential.
Renault recommends a mineral or semi-synthetic 10W-40 or 15W-40 oil meeting ACEA A2/B2 specifications. Using the correct viscosity is vital to ensure proper lubrication of the camshaft and rocker arms and prevent premature wear.
