The Renault C2J 767 is a 1,397 cc, inline‑four naturally aspirated petrol engine produced between 1985 and 1992. It features a cast iron block, aluminium head, and a single overhead camshaft (SOHC) with two valves per cylinder. This design prioritised simplicity and cost‑effectiveness for Renault's entry‑level and supermini models of the era.
Fitted primarily to the Super 5 and early Clio models, the C2J 767 was engineered for economical, reliable urban commuting. Its…
Production years 1985–1992 meet applicable French and EU emissions standards for their respective model years (EU Directive 88/77/EEC).
The Renault C2J 767 is a 1,397 cc inline‑four naturally aspirated petrol engine engineered for superminis and entry-level hatchbacks (1985-1992). It combines a simple SOHC valvetrain with carburetted fuel delivery to deliver dependable, economical performance. Designed to meet the emissions standards of its production era, it prioritises mechanical simplicity and serviceability.

The Renault C2J 767 was used across Renault's Super 5 platform with transverse mounting. This engine received minor carburettor and ignition system revisions throughout its production run, creating subtle differences in tuning and emissions compliance. All adaptations are documented in OEM technical bulletins.
The C2J 767's primary reliability concern is the potential for cylinder head gasket failure, particularly on pre-1990 models or those subjected to overheating. Renault internal service data indicated a higher-than-average replacement rate for this component in the late 1980s. Regular coolant system maintenance and avoiding overheating make using the correct revised gasket critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The C2J 767 is a fundamentally simple and robust engine. Its long-term reliability is good, provided the known cylinder head gasket issue is addressed with the correct revised part and the engine is not allowed to overheat. Regular maintenance of the ignition and fuel systems is key.
The most frequent issues are premature cylinder head gasket failure (especially on early models), carburettor clogging or leaks, wear in the distributor and ignition points, and general cooling system leaks from hoses or the water pump.
The C2J 767 was primarily used in the Renault Super 5 (1985-1990) and the very early first-generation Renault Clio (1991-1992, specific 1.4L variants). It was the 1.4L petrol option for these models during those years.
Minor tuning is possible via carburettor jetting, performance air filters, and exhaust upgrades, yielding modest gains. Significant power increases are limited by the SOHC 8-valve head design and would require major, often uneconomical, modifications.
Real-world fuel economy typically ranges from 6.5 to 8.0 L/100km (43-35 mpg UK) combined, depending on the model, driving style, and condition. Its small displacement makes it quite economical for city driving.
No. The Renault C2J 767 is generally considered a non-interference (or 'free-wheeling') engine. If the timing chain fails, the pistons and valves will not collide, preventing catastrophic internal damage.
Renault typically recommended a 10W-40 or 15W-40 mineral or semi-synthetic oil meeting API SF/CC specifications for the C2J 767. Always consult the specific owner's manual for your vehicle's year.
