What to Do When Engine Oil Pressure is Too High?
1 Answers
Engine oil pressure being too high can be judged and handled as follows: 1. Clogged oil filter The oil filter is a key component for filtering engine oil. If it becomes clogged, it can cause abnormal increases in oil pressure. Therefore, it is essential to regularly inspect and maintain the oil and filter, ensuring the quality of the added oil is up to standard. 2. Pressure relief valve clogged or improperly adjusted To prevent excessive oil pressure in the lubrication system, which increases engine power consumption and causes leaks at sealed connections in the oil circuit, a pressure relief valve is installed in the main oil passage or oil pump. Its function is to limit the oil pressure in the lubrication system, keeping it within the specified range. A faulty pressure relief valve is also one of the causes of excessively high oil pressure. 3. Excessive clearance in engine crankshaft bearings or connecting rod bearings If the engine feels heavy when rotating, it may be due to the crankshaft being too tightly assembled, leading to high oil pressure. Professional tools are required for adjustment. 4. Oil viscosity is related to oil quality. The higher the viscosity, the better the oil's resistance to high temperatures. However, higher viscosity is not always better. It is sufficient to use an oil grade that matches the engine.
