The cover has been designed specifically for the construction of powertrains used in the BMW 5 Series E39 and BMW X5 E53. This means that:

• the geometry of the component is consistent with the factory rear engine assembly,
• the layout of the mounting points corresponds to the manufacturer's original solutions,
• compatibility with other valve system components is maintained.

As a result, the cover is suitable both for standard replacement of a worn part and for more extensive service work within the cylinder head and engine block.

Performance characteristics and installation

As an item from the Tappet and Valve Covers category, this product is important from the perspective of long-term powertrain operation. A properly selected and installed rear valve cover:

• limits the risk of contaminants entering the valve zone,
• supports the maintenance of stable operating conditions for timing mechanisms,
• facilitates maintaining a seal at the rear of the engine.

The item is used, which in practice means it comes from vehicle dismantling and can be a cost-effective solution while maintaining the original BMW design specifications.

Application in service and modernization
