One of the likely causes of a dull clack or noise in the operation of the Renault Sandero engine is the setting of the valves which has been broken. This noise is tapped at the top of the engine.
However, the knock may also mean a serious malfunction in the engine, so it is better to stop moving and get to the tow truck or the tow truck. For example, the work of the engine with the sound of the original bearings (hearing at the bottom of the engine) or the steps of step bearings (in the middle of the engine) can lead to an irrevocable breakdown.
