Can You Still Drive with Excessive Oil Pressure?
1 Answers
If the oil pressure warning light comes on while driving, indicating excessive oil pressure, it is advisable not to continue driving. Continuing to drive may cause further damage to the engine. You should first pull over and check whether the oil level is normal, then contact a repair shop for assistance. The causes of excessive oil pressure include: 1. The oil viscosity is too high, the main oil passage is blocked, the cylinder block is clogged, or the oil filter is obstructed. If the engine is running normally but the oil gauge reading exceeds the specified value, power decreases, and sometimes the sensor or oil filter housing may be damaged. It is recommended to remove the filter and check whether the filter element is too dirty or clogged, or whether the bypass valve spring is too strong to open, leading to excessive oil pressure. 2. Check whether the pressure relief valve spring is too tight or the spring force is too strong to open. In some models, if the pressure relief valve piston is stuck and cannot lift, it may also cause excessive oil pressure. If the above checks show no abnormalities, inspect whether the oil passage in the cylinder block leading to the crankshaft bearing (except for newly assembled engines) is blocked. A blocked oil passage can easily cause high oil pressure and bearing failure.
