Bremmen Parts BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW 5 Series G30 (2017+)

Gaskets are key to a properly running and clean engine. They obviously prevent fluid leaks but they're also critical in keeping air either in or out... Air leaks after the air flow meter, also known as vaccum leaks, can induce lean running conditions, fault codes, and poor running conditions. Other seals and gaskets are designed to keep air in. With the sensitivity of OBD systems, leaks will lead to fault codes very quickly which can be tough to diagnose and prevent you from passing state inspections.

We insist on Original BMW or OEM gaskets whenever possible.

The crankshaft seal, commonly known as the main seal, is essential for preventing oil leaks where the crankshaft passes through the engine block. Located at the rear of the engine, this seal creates a secure barrier between the moving crankshaft and stationary engine parts, ensuring oil remains within the engine.

By maintaining proper oil pressure, the crankshaft seal helps lubricate critical internal components, promoting smooth engine performance and reducing the risk of damage caused by oil loss. Replacing a worn or leaking crankshaft seal is crucial to safeguarding your engine's reliability and longevity.
