How to deal with the rattling sound of the new Santana engine

The new Santana engine has a rattling sound. We need to check whether the quality of the added engine oil is too poor or the engine oil has not been changed for a long time, resulting in insufficient engine oil and abnormal noise. Engine oil plays a cooling and lubricating role in the engine. When the oil quality is too poor or lacking, it is easy to cause too much friction between the throttle valve and the guide pipe and the hydraulic tappet, which leads to obvious abnormal noise of the engine. In this case, the engine oil must be replaced or added immediately to avoid engine damage caused by continuous friction. In addition, if the cold car clicks when it starts, and the sound is even and soft, it is usually unnecessary to pay attention. This is because the internal parts of the cold car are not fully lubricated and the working temperature is not enough. It can be solved by heating the car on the spot for a while.
