• Functions and effects
◦ Sealing function: The main role of the oil filter cover is to seal the engine’s oil filter and prevent oil leakage. By closely fitting with the filter housing and using components such as sealing rings, it ensures that oil does not leak from the top of the filter, maintaining a stable oil level inside the engine.
◦ Pressure balance: When the engine is operating, internal temperatures are high and the oil expands when heated. The oil filter cover helps balance the internal pressure of the engine, preventing excessive pressure from causing engine failure and maintaining the normal operating pressure of the lubrication system.
◦ Preventing impurities from entering: The oil filter cover forms a barrier that prevents external dust and impurities from entering the oil filter and the engine, protecting the engine from wear caused by harmful particles and extending its service life.
◦ Facilitating oil changes: When changing the engine oil, the oil filter cover needs to be removed to take out the old oil filter and install a new one. Its design makes this operation easier, and some oil filter covers are also equipped with an oil drain valve for convenient discharge of old oil.​
