Detailed Description

Mahle HS54868 is engineered for BMW engine sealing service where the cylinder head, intake, exhaust, and upper-engine interfaces need to be resealed during repair. The multi-layered steel construction at the head and exhaust sealing points supports consistent clamping and sealing performance, while the molded rubber intake manifold gasket helps address intake-side leakage concerns. This set is a practical choice for BMW 745i, BMW 745Li, BMW 545i, BMW 645Ci, and BMW X5 repairs that require OE-standard gasket materials and fitment-specific components.

This part cross-references BMW 11 12 7 518 017 for the same application. The Mahle HS54868 is a strong match for technicians and DIY repair jobs focused on restoring sealing integrity after head service or upper-engine teardown.

Common Repair Uses

• Oil or coolant leakage at the cylinder head sealing surface
• Intake manifold vacuum leaks or sealing loss
• Exhaust manifold gasket seepage or exhaust leakage
• Valve cover or plenum sealing issues during top-end service
• Fuel injector O-ring or valve stem seal replacement during engine repair

Installation Notes

Confirm engine code and application notes before ordering, since this listing states head gasket not included and cylinder head bolts are not included. Because this is a torque-to-yield application, cylinder head bolt replacement is recommended during installation. Clean all mating surfaces thoroughly, inspect the cylinder head for flatness, and follow BMW torque procedures exactly to avoid sealing failure.

Quality Assurance

Mahle gaskets are used by OEMs and technicians worldwide, and this set is built to OEM-standard expectations for fit and sealing performance. The HS54868 is intended for professional-level engine repair where accurate materials and application-specific sealing components matter.
