Oil Filter Bypass Valve

The engine oil filter bypass valve, also known as an oil pressure relief valve, allows oil to pass through to the engine if the oil filter becomes clogged, or if the oil is too thick from being cold. This helps prevent oil starvation and engine damage. It is important to regularly change your oil according to your vehicle's maintenance schedule. This can help minimize sludge buildup that may cause the bypass valve to stick. A stuck open valve may cause a lack of oil pressure that can cause serious engine damage. A stuck closed valve may damage the oil filter, oil filter gasket, or even blow the oil galley plugs in the engine. If you suspect there is an issue with the bypass valve, shop O’Reilly Auto Parts.
