Oil Filter Housing Gasket

Oil Filter Housing Gaskets and Sealing Components A-Z Car Parts Halifax supplies high-quality Oil Filter Housing Gaskets designed to seal the critical connection between the oil filter housing and the engine block. These gaskets are essential for containing high-pressure motor oil and preventing catastrophic leaks. We stock a wide range of profiled rubber, metal, and Viton seals for all major vehicle manufacturers.

Function of the Oil Filter Housing Gasket The oil filter housing (or filter stand) bolts to the engine block and directs oil flow into the filter. The gasket seals this mating surface.

• Pressure Containment: Must withstand oil pressures ranging from 10 to 80+ PSI.

• Fluid Separation: On many modern engines (e.g., BMW, Mini, VAG), the housing also manages coolant flow for the oil cooler. The gasket prevents oil and coolant from mixing (cross-contamination).

• Thermal Resistance: Designed to endure extreme temperature cycles from cold starts to operating temperatures of 100°C+.

Symptoms of a Failed Housing Gasket The oil filter housing gasket is a common failure point on ageing engines. Signs include:

• Oil Puddles: Fresh oil pooling under the engine or on the undertray.

• Burning Oil Smell: Oil dripping onto the hot exhaust manifold or catalytic converter.

• Oil in Coolant: A "mayonnaise" sludge in the expansion tank indicating the gasket has breached internally (common on oil cooler modules).

• Low Oil Levels: Frequent top-ups required without visible blue smoke from the exhaust.

• Dirty Engine Block: Heavy oil residue running down the side of the engine.

Causes of Failure

• Thermal Hardening: Over years of heat cycling, the rubber gasket loses its elasticity, becomes brittle, and flattens out (plasticizes), losing its seal.

• Improper Installation: Pinching the gasket or failing to clean the mating surface during a previous repair.

• Overtightening: Warping the housing flange by applying too much torque to the mounting bolts.

Replacement Advice Replacing the Oil Filter Housing Gasket is often labor-intensive, so using a high-quality part is crucial.

• Replace the Oil Cooler Gasket: If your housing has an attached oil cooler, always replace the cooler gaskets at the same time.

• Clean Thoroughly: The engine block surface must be completely free of old gasket material and oil before fitting the new seal.

• Torque Specs: Always tighten housing bolts to the manufacturer's specified torque pattern to prevent leaks.
