How to Fix a Leaky Oil Filter


You should change the oil filter on a vehicle every time the oil is changed. Changing the oil and filter regularly is one of the cheapest and most effective ways to prolong the life of an engine.

Occasionally an oil filter will leak after installation. A seal should form between the bottom of the oil filter and the flat plate around the oil coupler fitting. Oil in an engine is under pressure, and an inadequate seal will leak.

Step 1

Verify that you have installed the correct oil filter. Check the numbers on the filter against the information provided by your vehicle’s manufacturer. Oil filters are matched to a specific engine, not a specific model of car. Many models of car are available with multiple engine types, each requiring its own oil filter.
