What is the Oil Pump Cover Gasket all about? Your oil pump, which is responsible for pumping oil through the engine, requires protection itself. It is mounted inside an oil pump cover, which can become the source of a leak (oil can leak out at the base where the oil pump cover attaches to the engine). This is prevented by an oil pump cover gasket.
