Corteco BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW E21 320i M10 1.8L

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 rear main oil seal or crankshaft seals is one of the most difficult to replace. However, they often fail, and when they do, your car will be marking it's territory with little oil drops wherever you park. Apart from making a mess, it can also cause oil to come in contact with the clutch surface. Replace yours and keep your oil in your engine.
