Can You Still Drive with Excessive Oil Pressure?

[Gray]

If the oil pressure warning light comes on while driving, indicating excessive oil pressure, it is recommended not to continue driving. Continuing to drive may cause further damage to the engine. You should pull over and check the oil level first, then contact a repair shop for assistance. More detailed information is as follows: 1. Causes of excessive oil pressure include: high oil viscosity, blockage in the main oil passage, blockage in the cylinder block, or a clogged oil filter. 2. During normal engine operation: if the oil gauge reading exceeds the specified value, power decreases, and sometimes the sensor or oil filter housing may be damaged, it is advised to remove the filter. 3. Check if the filter element is too dirty or clogged: or if the bypass valve spring is too strong to open, leading to excessive oil pressure. 4. Check if the pressure relief valve spring is too tight: or if the spring is too strong to open. In some models, if the pressure relief valve piston is stuck, it may also fail to lift, causing excessive oil pressure. 5. Check if the oil passage in the cylinder block leading to the crankshaft bearing is blocked: 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.
