Purpose and function in the timing system

The Audi A4 B7 1.8 T BFB Engine Front Camshaft Sealing Flange End Cover operates at the front of the petrol engine, in the immediate vicinity of the timing drive. Its tasks include:

• maintaining a stable position for the crankshaft seal on the timing side,
• reducing oil loss in the chain or belt operating zone,
• protecting against contaminants entering the timing chamber,
• contributing to a sealed housing for the front part of the engine.

Thanks to a properly selected shaft sealing flange, the timing system remains clean, and components operating in oil are better protected against premature wear.

Benefits of using an original Audi cover

Using a shaft sealing flange sourced from Audi ensures factory-spec fitment for the 1.8 T BFB unit. This means:

• precise fit with the front part of the engine block and timing accessories,
• correct axial shaft guidance, which promotes even seal performance,
• preservation of factory geometry in the timing drive area,
• easier installation without the need for modifications.

For 1.8 T BFB petrol engines, maintaining a seal at the front of the unit is particularly important – it affects engine refinement, the cleanliness of the timing chamber, and the stability of lubrication parameters.

Condition, application, and installation aspects

The presented Audi A4 B7 1.8 T BFB Engine Front Camshaft Sealing Flange End Cover comes from the secondary market, allowing for an economical repair while maintaining the original design. The component is intended for installation at the front of the petrol engine, replacing the factory cover after the timing accessories have been removed.

When replacing the cover, it is recommended to:

• check the condition of the shaft seal itself and consider replacing it at the same time,
• thoroughly clean the mating surface on the engine block,
• check the condition of components in the timing cover group in the immediate vicinity.

Expanding timing system service and expert content

While working on the shaft sealing flange, it is worth comprehensively assessing the condition of the entire timing drive – both in Audi petrol engines and other units. For comparison, in popular BMW N47 units, it is crucial to monitor the wear of the chain and associated components.
