Renault Camshaft Dephaser Seal – Clio 2/3 RS & Mégane 3 RS

Renault Sport Camshaft Dephaser Solenoid Oil Seal: Prevent Oil Leaks

On Renault Sport engines, maintaining the correct sealing of upper engine components is essential for reliable maintenance. A worn, damaged or incorrectly fitted camshaft dephaser solenoid oil seal can cause oil to leak around the camshaft timing solenoid.

The Renault camshaft dephaser solenoid oil seal, reference 7700106385, is designed to provide sealing at the solenoid mounting point. It is intended for compatible Renault Clio 2 RS, Clio 3 RS and Mégane 3 RS applications. This seal should be inspected when replacing the solenoid or servicing the variable valve timing system.

Ignoring a persistent oil leak can lead to additional oil consumption, engine bay contamination and further repair work. Identifying the source of the leak early helps determine whether the seal needs replacing or whether another component is responsible.

Important: this seal provides an oil-tight connection. It does not replace the camshaft timing solenoid and will not correct an electrical fault, a control issue or a mechanical malfunction within the variable valve timing system.

A Key Seal for the Camshaft Variable Valve Timing System

The camshaft dephasing system, also known as variable valve timing (VVT), adjusts camshaft timing according to engine operating conditions. On the relevant Renault Sport engines, the solenoid controls the hydraulic operation of the camshaft phaser.

The oil seal helps prevent leaks between the solenoid and its mounting point. If the seal becomes damaged or is incorrectly installed, oil traces may appear around the affected area. A visual inspection can help identify a leak, although further diagnosis may be required to confirm its exact source.

Replacement and Engine Maintenance Advice

When replacing the oil seal, inspect the solenoid, its mounting point and the contact surfaces. Installation should be carried out carefully to avoid pinching, deforming or damaging the new seal.

After installation, check the area for leaks and inspect for any new traces of oil. If the leak persists, further investigation may be necessary to identify another possible source.

Frequently Asked Questions About Seal 7700106385

What are the symptoms of a worn camshaft dephaser solenoid oil seal?
Oil traces around the solenoid or its mounting point may indicate a sealing problem. However, the exact source of the leak should be confirmed before replacing the part.

Is this seal compatible with the Clio 2 RS and Clio 3 RS?
Part number 7700106385 is listed for Clio 2 RS 172/182 and Clio 3 RS 197/200 applications with the corresponding mounting arrangement. Confirm the part number before ordering.

Is this seal also suitable for the Mégane 3 RS?
It is listed for Mégane 3 RS 250, 265 and 275 applications, as well as the Mégane 3 RS N4 application. Always confirm the correct fitment for your engine.

Does the camshaft timing solenoid need to be replaced at the same time?
Not necessarily. If the solenoid is operating correctly and the leak is caused only by the seal, replacing the seal may be sufficient. A faulty solenoid requires a separate diagnosis.

Where can I find additional parts for this repair?
The camshaft timing solenoid and other potentially required components can be found at the bottom of the product page you are currently viewing.
