The rubber buffer acts as a flexible mounting point between the oil tank and chassis, absorbing vibrations and movement generated by the engine and oil system. It ensures the oil tank remains securely positioned while preventing excessive stress on connected oil lines and fittings.
Functions & Technical Role
• Vibration isolation: Reduces transfer of engine vibrations to the chassis
• Component support: Secures the oil tank in position
• Stress reduction: Protects oil lines and connections from movement
• Noise damping: Minimises vibration-related noise
• OEM construction: Bonded rubber-metal design for durability and flexibility
Fitment / Position on car
• Fitting position: Engine / oil system mounting
• Location: Between engine oil tank and body/chassis mounting points
• System: Engine lubrication / oil tank support
Cross Reference / Superseded Numbers

Over time, rubber mounts can harden, crack, or collapse, leading to:
• Increased vibration and noise
• Stress on oil tank and pipe connections
• Potential oil leaks or fatigue damage
• Reduced overall system stability
Replacing worn buffers with genuine Porsche OE parts restores proper mounting support and protects the oil system.
