Do oil filters have pressure relief valves?
The bypass valve – otherwise known as a pressure relief valve – is an integral part of the oil filter. The valve is designed to open when the oil filter becomes clogged or when the oil is too thick. The oil then goes straight to the engine to prevent starvation and damage.
Where is oil pressure relief valve located?
oil pump housing
Modern vehicles include the pressure relief valve in the oil pump housing which can be found inside the engine behind the timing cover or the oil pan. Because of this, a vehicle service manual is mandatory to find the location of the valve as the design varies.
What will cause high oil pressure?
The resistance the oil faces in flowing through a partially or completely obstructed passage could be one reason for high oil pressure. Changing the viscosity grade to a thicker or thinner oil has an effect on the oil pressure. If the oil is too viscous or not viscous enough, it might be the wrong oil for your engine.
What is the function of the bypass valve in an oil filter?
The bypass valve – otherwise known as a pressure relief valve – is an integral part of the oil filter. The valve is designed to open when the oil filter becomes clogged or when the oil is too thick.
Why does the oil bypass valve not open?
This allows the oil to bypass the filter through a center tube. The oil then goes straight to the engine to prevent starvation and damage. If the bypass valve doesn’t open when needed, the filter will swell and eventually burst.
What causes oil to bypass the filter on a Mini Cooper?
One of the valves inside the filter base is damaged (missing pieces). 3. Aftermarket oil filter with inadequate ‘stiffness’ on the ends of the filter causing oil to bypass the filter (Wix filter caused this problem for one customer).
Why is an oil filter important to an engine?
Oil filters are a key part in the engine lubrication system. They remove contaminants which could cause long-term damage to your engine. Clean motor oil is crucial to the health of the engine and if left unfiltered, it could become saturated with tiny, hard particles that can wear surfaces of internal parts.
