During vehicle operation, there may be abnormal noise from the filter position, which is mostly a fault signal. Different abnormal noises correspond to different problems, and accurate troubleshooting can solve them.

Firstly, there is a strange noise of sizzling water, which is mostly caused by slight blockage of the engine filter, poor oil circulation, and high-pressure flushing of the oil filter element, accompanied by a slight decrease in power. It is necessary to check and replace the engine filter.
Secondly, there may be rattling vibrations, loose installation of the machine filter, insufficient torque, and shaking of the vehicle body after driving vibrations, which can cause abnormal noise when colliding with surrounding components. Re tightening it according to standards can solve the problem.
Thirdly, there is a dull buzzing noise, severe blockage of the filter element, abnormal oil pressure, blocked oil circulation, and poor engine lubrication causing abnormal noise. It is necessary to immediately replace the filter and check the oil pressure.
Fourthly, there is abnormal noise caused by metal friction. Poor quality filters may have internal filter materials falling off or debris shaking and rubbing against the body, resulting in sharp abnormal noise. It is necessary to immediately replace the filter with a new one to avoid debris blocking the oil circuit.

Do not ignore the occurrence of abnormal noise from the engine filter. Failure to handle minor faults can cause significant engine damage.
