BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

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.

Rein Rear Crankshaft Seal for many BMW models is an OE-equivalent replacement for the rear main oil seal. When the seal fails, oil drips onto the driveway and can reach the clutch surface. Replacing it during a clutch job is the practical time to do it, since the transmission is already out.

This is the sealing o-ring used for many oil cooler kits on various BMW models. They're also a prime source for oil leaks because the o-ring gets 'flat' or shrinks or becomes damaged. These are usually easy to change though which puts an end to annoying small oil leaks.
