Causes and solutions of low engine oil pressure

Low engine oil pressure may cause damage to engine parts such as pistons, crankshafts and their large and small tiles. Here is a brief introduction to the reasons and solutions for low oil pressure:

1. The engine oil storage is too small, causing the lubrication system to have no or little oil, resulting in low oil pressure. Solution: refuel.

2. Dirty or viscous oil causes the oil pump to be unable to effectively suck and pump the oil, resulting in low or no oil pressure. Solution: change the oil.

3. If the engine oil is thin or the engine oil becomes thin due to high engine temperature, it will leak from the gaps of the friction pairs of the engine, resulting in low oil pressure. Solution: change the oil or overhaul the cooling system.

4. Oil leakage from the oil pipe, damage to the oil pump or excessive wear of its parts will cause the oil suction, pump output to be reduced, or no amount at all, resulting in low or no oil pressure. Solution: overhaul.

5. Excessive clearance between the crankshaft and the large and small tiles causes oil leakage, resulting in low oil pressure. Solution: overhaul.

6. The spring of the pressure limiting valve or the pressure relief valve is too soft, the function of the valve is lost or weakened due to hairpin or steel ball damage, and the oil pressure is reduced. Solution: replace and overhaul.

7. Low oil pressure caused by oil sensor plug, pressure gauge or circuit failure. Solution: replace and check.
