This rubber buffer supports the oil tank while isolating it from engine vibrations and chassis movement. It reduces stress on oil lines and surrounding components, helping maintain system integrity and preventing premature wear.

Function
• Supports and stabilises the engine oil tank
• Absorbs vibration between tank and chassis
• Reduces stress on oil lines and connections
• Prevents metal-to-metal contact
• Helps maintain correct positioning of oil system components

Over time, rubber mounts degrade due to heat, oil exposure, and age. A worn buffer can lead to increased vibration, stress on oil lines, and potential leaks. Replacing it restores proper isolation, protects the oil system, and helps maintain overall engine reliability.

When to replace
•  Rubber shows cracking, splitting, or hardening
•  Increased vibration or movement of oil tank
•  During oil line or tank servicing
•  Signs of oil system stress or misalignment
•  As part of engine bay restoration or maintenance
