Is oil leakage in an electric tricycle motor serious?

[StElaina]

Oil leakage in an electric tricycle motor is serious. It is caused by a loose valve. Solutions: Replace the valve if the connection is loose. Tighten or replace the connection. First, immerse the stuck fuel injector in diesel or engine oil to heat it, then remove it, wrap it with a cloth, and use pliers to grip the needle valve and gently work it to remove the needle valve from the needle valve body. Precautions for motor oil leakage: Unclean fuel or impurities in the high-pressure fuel line can prevent the needle valve assembly from sealing properly, allowing high-pressure gas from the combustion chamber to backflow and damage the needle valve assembly. This leads to oil leakage in the electric tricycle motor. Besides the above issues, dirt on components such as the injector pressure adjustment spring and tappet can migrate to the injector through the tappet.
