What Causes the Clicking Sound While Driving?
1 Answers
There are many possible reasons for the clicking sound while driving: it could be due to engine oil issues, such as using low-quality oil, not changing the oil for a long time, or insufficient oil levels. These conditions can increase friction between the valves and guides, as well as hydraulic lifters, making various engine noises more pronounced. More details are as follows: 1. Engine-related causes: The clicking sound is often due to valve noise, caused by excessive valve clearance or wear, resulting in metal clashing sounds. Some vehicles may produce this sound when cold-starting due to poor lubrication conditions, excessive wear between pistons and cylinder walls, or when the clearance tolerance between pistons and cylinder walls exceeds the normal range, causing the piston skirt to hit the cylinder wall during engine operation. 2. Tire-related causes: When driving on highways with windows open, a noticeable 'clicking' sound from the body may indicate stones embedded in the tires. If safe, you can pull over to the right and check the tires.
