Should the Ticking Sound of Valves Be Repaired
2 Answers
If the ticking sound of the valves is only slight, it indicates that the valve clearance is small and no repair is needed. However, if the ticking sound is loud, it is necessary to check the valve clearance and whether the valves are severely worn to avoid engine damage leading to major repairs. More information about the ticking sound of valves is as follows: 1. Symptoms of valve ticking include: difficulty starting the vehicle, lack of power when overtaking, decreased engine power, and carbon deposits on the conical surfaces of the valves and valve seats. 2. Repair methods for valve ticking: The grinding method can be used. Clean the carbon deposits on the valves and then grind them to achieve a certain roundness and cylindricity. After installation, measure whether the valve clearance is within the normal range.
I encountered this situation last year when my car also made a similar valve ticking sound. At first, I thought it was just normal engine noise and ignored it. But the sound grew louder, and I worried it might affect the engine's performance, so I took it to a trusted repair shop for inspection. The mechanic said it was caused by excessive valve clearance or insufficient lubrication, and prolonged wear could lead to more severe damage. After he adjusted the clearance and changed the oil, the noise disappeared. Fortunately, I caught it in time to avoid engine overheating or failure. I suggest you first check if the oil level is sufficient—if it's below the minimum line, top it up. If the sound persists or gets louder, don’t delay; take it to a professional shop immediately to avoid small savings now leading to big engine repair costs later. Safe driving is the priority—don’t take risks just to avoid hassle.
