What are the Symptoms of High Engine Oil Pressure?


Bookmark and Share

There are no symptoms of high engine oil pressure, unless you consider the reading on the oil pressure gauge a symptom. High oil pressure can be caused by using heavier weight oil than the vehicle manufacture suggests using. It can also be caused by a dirty oil filter, or other restrictions in the engine’s oil passages. Barring these types of issues, the most likely cause of a high oil pressure reading is a defective component within the oil pressure sensor/measurement system. Placing an external gauge into the port occupied by the sending unit will let you know if you have high oil pressure, or a defective component.
