What are the causes of low oil pressure?

[Amy]

Reasons for low engine oil pressure: 1. Wear of the oil pump or pressure relief valve, or presence of foreign objects. 2. Cracked connecting pipe from the oil pump to the cylinder block or damaged gasket. 3. Damage to the pressure relief valve in the oil filter housing. 4. Insufficient engine oil storage leading to low oil pressure, requiring timely replenishment. The following is an introduction to the engine: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Internal combustion engines typically convert chemical energy into mechanical energy. The term engine can refer to the power generation device or the entire machine including the power unit.
