How to check the motor oil pump oil supply is normal?
Generally in the cylinder head have oil inspection screw, screw out, see oil quantity will know (start 0)You can also remove the cylinder head, start to see how much oil spray, but only suitable for centralized models, and some cylinder head and rocker arm is integrated, and can not start the demolition
Loosen the oil passage screw for the cylinder head or open the valve cover screw. Increase the oil flow at the throttle, which indicates that the oil pump is good
In the premise of the normal amount of oil, usually need to check whether the oil pressure is normal (usually around 0.3MPa), if the oil pressure is low, usually the oil circuit, overflow valve failure or oil pump failure. After cleaning and adjusting the oil relief valve, the pressure is still low. The fault must be the oil pump failure.The effect of the oil pump is to press the engine oil to a certain pressure and force it to the surface of each part of the engine. If the oil pump is damaged or leaking, it is necessary to disassemble the oil pan, take out the oil pump and replace it, and clean or replace the oil pump inlet strainer at the same time.
