Elring 423.471 Gasket, timing case

Elring 423.471 Gasket – Timing Case

The Elring 423.471 gasket is a precision‑engineered sealing solution designed specifically for the timing case of BMW engines. Crafted from high‑performance rubber, this component ensures optimal fluid containment and noise reduction within the engine bay.

Key Material Characteristics

The gasket’s core material is rubber (caucho), chosen for its excellent resilience, temperature tolerance, and chemical resistance. This allows it to maintain a tight seal across a wide range of operating conditions, from cold starts to high‑temperature running.

Design & Compatibility

The gasket is engineered to fit the timing case assembly found in various BMW models, including the 3 Series (E36, E46), 5 Series (E34), and Z3. Its dimensions are calibrated to match OEM specifications, providing a seamless replacement that restores factory performance.

Installation Overview

1. Preparation: Clean the timing case surface thoroughly to remove oil, dirt, or old gasket material.
2. Placement: Position the new 423.471 gasket onto the cleaned area, ensuring it sits flush and evenly.
3. Reassembly: Reinstall the timing cover, tightening bolts in a cross‑pattern to achieve uniform pressure.
4. Verification: Inspect for any gaps or misalignments; a properly installed gasket should exhibit no visible leaks.

Performance Benefits

• Leak Prevention: Maintains engine oil and coolant integrity, reducing the risk of internal contamination.
• Noise Dampening: The rubber material absorbs vibrations, contributing to a quieter engine operation.
• Durability: Designed for long service life under typical automotive stressors.

Additional Technical Note

While the primary part number is 423.471, related components such as the 423.531 gasket may be required for specific engine variants or additional sealing tasks within the same assembly.

Maintenance Tips

• Inspect the gasket during routine maintenance checks, especially after any timing cover removal.
• Avoid using abrasive cleaners that could damage the rubber surface.
• If you notice any signs of wear—such as cracks or softening—replace immediately to prevent leaks.

Conclusion

The Elring 423.471 gasket delivers reliable sealing performance for BMW timing cases, combining high‑quality rubber construction with precise engineering. Its straightforward installation and proven durability make it an essential component for maintaining engine integrity and ensuring smooth operation.
