Low crankcase oil viscosity or insufficient oil. Pressure limiting valve spring is too soft or broken. Oil filter bypass valve spring too soft and broken. Loose lubricating oil inlet pipe joint or oil pipe rupture. The oil pump is not working well and the oil circuit is seriously leaking. Gasoline pump diaphragm rupture, gasoline leakage into the crankcase dilution oil. Cylinder liner damage, cooling water leaking into crankcase. The matching clearance of crankshaft main bearing, connecting rod bearing and cam bearing is too large and leaks. The oil filter is blocked, so that the opening pressure of the bypass valve is too high or stuck, and the oil cannot enter the main oil passage. Oil collector clogged.
It might be!!
1. Low viscosity of crankcase oil or insufficient oil.
2. The pressure limiting valve spring is too soft or broken.
3. The oil filter bypass valve spring is too soft and broken.
4. The lubricating oil inlet pipe joint is loose or the oil pipe is broken.
5. The oil pump is not working well, and the oil circuit is seriously leaking.
6. The diaphragm of the gasoline pump is broken, and the gasoline leaks into the crankcase to dilute the oil.
7. The cylinder liner is damaged and the cooling water leaks into the crankcase
8. The matching clearance of crankshaft main bearing, connecting rod bearing and cam bearing is too large and leaks.
9. The oil filter is blocked, so that the opening pressure of the bypass valve is too high or stuck, and the oil cannot enter the main oil passage.
10. The oil filter is blocked.
It might be!!
1. Improper selection of lubricating oil grade and excessive viscosity
2. Failure of pressure limiting valve in oil pump
3. The lubricating oil passage of the cylinder block is blocked, which prevents the flow of lubricating oil
4. The clearance of the main bearing or connecting rod bearing is too small, which affects the flow of lubricating oil
5. The oil filter element is blocked and the bypass valve is difficult to open
6. Lubricating oil pressure gauge or sensor is not working well
Can the abnormal oil pressure continue to open?
Note:
If the oil pressure is abnormal, it should be stopped immediately, and it is absolutely impossible to continue driving until the fault is eliminated.
