BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW 5 Series E34 (1987-1995)

Clear BMW chassis

Please ensure your correct model is selected

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.

Is your BMW showing signs of an oil leak? One of the most common causes is a failing oil pan gasket, a vital component that prevents oil loss and keeps your engine running smoothly. Over time, the gasket—typically made from metal with a durable rubber sealing bead—can wear out due to heat cycles, pressure fluctuations, and general aging. When the rubber bead deteriorates, it compromises the seal and results in leaks.

Ignoring an oil pan gasket leak can lead to more significant issues, such as low oil levels, reduced engine efficiency, and even serious engine damage. Addressing this problem early is crucial to maintaining your vehicle's performance and longevity.

For a reliable solution, choose Corteco. Known for their precision engineering and OE-grade materials, Corteco gaskets are crafted to deliver a perfect fit and exceptional durability. Trust Corteco to provide a high-quality replacement that ensures your BMW stays leak-free and running at its best.

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.

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.
