Why is the Leiling engine so noisy?

[OJudah]

There are many reasons for the loud noise of the Leiling engine, such as engine parts wear, muffler aging, poor lubrication system, excessive carbon deposits, etc., which can all generate noise. By adding shock-absorbing plates and sound-absorbing pads, the road noise and tire noise of the engine can be effectively solved. The Leiling is a model under GAC Toyota Motor Co., Ltd., with body dimensions of 4640mm in length, 1780mm in width, and 1455mm in height, and a wheelbase of 2700mm. In terms of appearance, the Leiling adopts the North American version styling of the car series. The front face design has increased lines compared to the old model, with raised front fenders on both sides, and the headlights have been changed to a hook style. The overall rear styling has been slightly modified, with a black horizontal chrome strip running through the taillights on both sides, and the lower black surround wrapping around the rear, changing the previous purely family-oriented image.
