Purpose and compatibility

The described cover is dedicated to the M62 petrol engine installed in BMW 5, 7, and X5 series models, on the right side of the power unit. The component works with the lubrication and timing system, providing adequate mechanical protection and reducing oil leaks in the area of cylinders 1–4.

Thanks to a design consistent with factory BMW standards, the cover maintains the correct geometry of the mounting points, which facilitates installation and allows for the proper routing of seals and accessories located in the upper part of the engine.

Construction and technical function

The right-side cylinder head cover performs several key functions in the M62 petrol engine:

• covers the moving timing components in the upper part of the head,
• stabilizes the position of the cover gasket, reducing the risk of leaks,
• supports the maintenance of proper oil pressure within the head area,
• protects the engine interior from external contaminants.

As an element from the Cylinder Heads group, the cover is an essential component during any intervention in the upper part of the power unit – both during repairs and when assembling the engine after an overhaul.

Application in the M62 petrol engine

The M62 engine is an advanced BMW petrol unit, where proper sealing and the rigidity of the cylinder head system have a direct impact on operating smoothness and durability. The right-side cover:

• ensures proper oil flow in the area of the valves and camshafts,
• limits evaporation and leakage of the lubricating medium,
• enables correct mounting of associated components in the upper part of the engine.

Choosing an original, used cover for a petrol engine allows for maintaining material and structural consistency with the other elements of the power unit, which is particularly important when servicing older BMW models.

Condition, installation, and benefits of use

The item is offered as a used cylinder head cover, which allows for economical repair while maintaining the manufacturer's original specifications. This type of part is particularly useful when the existing cover has suffered mechanical damage, deformation, or shows persistent leaks.

The main benefits of using this cover include:

• maintaining factory fitment for the M62 engine head,
• the ability to restore the tightness of the right side of the power unit,
• reducing service costs through the use of an original used component.
