Diagram Ref No 20

Manufactured using a durable rubber-metal bonded construction, this component is engineered to withstand engine bay temperatures, oil exposure, and mechanical stress while maintaining flexibility and structural integrity.

A direct replacement part, this oil thermostat mounting buffer is essential for maintaining proper oil system function and preventing component wear.

Key Features

• Direct replacement bonded rubber-metal buffer
• Suitable for Porsche 964 (1989–1994)
• Designed for oil thermostat housing mounting
• Reduces vibration and mechanical stress
• Durable rubber-metal bonded construction
• OEM-style fit and function

Function and Purpose

This rubber buffer acts as a mounting support and vibration isolator for the oil thermostat housing.

It helps to:

• Secure the oil thermostat in its correct position
• Reduce vibration transfer within the oil system
• Prevent stress on oil lines and connections
• Protect surrounding components from wear

Why Replace Your Oil Thermostat Mounting Buffer

Over time, rubber-metal mounts can degrade due to heat, oil exposure, and vibration.

Common issues include:

• Cracked or hardened rubber
• Reduced vibration damping performance
• Movement or misalignment of the thermostat housing
• Increased stress on oil system components

Replacing the buffer restores proper mounting stability and helps maintain reliable oil system operation.
