Genuine 057 103 831 B Valve Cover Bolt Bushing OEM VW Audi

The Genuine 057 103 831 B is an OEM valve cover bushing designed for Volkswagen and Audi vehicles equipped with the 4.2L V8 and related engine families. As a factory-original component sourced directly from the manufacturer, this bushing meets the exact tolerances and material specifications required for proper engine sealing and performance.

Valve cover bushings serve as isolation grommets for the valve cover fastening bolts or studs. They cushion the bolt against the valve cover, absorbing vibration and preventing the cover from cracking under torque. Over time, these rubber/elastomeric bushings harden, crack, or collapse — leading to oil leaks and loose valve cover fasteners. Replacing worn bushings with a genuine OEM part restores a proper seal and protects against future leaks.

Key Features:

• 100% genuine OEM part — exact factory fit and finish
• Manufactured to original equipment specifications for precise fit
• Elastomeric construction absorbs vibration and dampens fastener stress
• Restores proper valve cover sealing when worn bushings cause oil leaks
• Direct replacement — no modifications required
• OEM Part Number: 057 103 831 B

For best results, inspect and replace all valve cover bushings as a set during any valve cover gasket service. Using genuine OEM components ensures compatibility and longevity consistent with original factory standards.
