What Causes the Ticking Sound When Accelerating in a Langdong?
2 Answers
Langdong accelerating with a ticking sound is mainly caused by the following reasons. Cold Start Reason: Generally, during a cold start, the engine sound of most cars will be slightly louder than when the engine is warm. As long as the sound is uniform and smooth, not harsh, it usually isn't a problem. This is because when the engine is cold, the gap between the cylinder wall and the piston hasn't reached its optimal size, and the lubrication from the engine oil isn't fully effective. Typically, when the engine block temperature reaches about 95 degrees, the sound will return to normal. Engine Oil Reason: Poor quality engine oil, not changing the oil for a long time, or lack of engine oil, among other situations, can easily increase friction between the valves and guides, as well as hydraulic lifters, making various sounds within the engine louder.
My Elantra had this issue before, making a ticking sound when stepping on the gas. It's most likely a problem with the valves or hydraulic lifters, especially more noticeable during cold starts. The engine design of the Elantra means even slightly larger valve clearances can cause this metallic tapping noise. It could also be due to the engine oil being too thin or not changed for a long time, leading to insufficient oil supply to the hydraulic lifters. Additionally, the carbon canister solenoid valve can produce a ticking sound when operating, which isn't a concern. It's best to first check the engine oil level and top it up if low. If the noise persists loudly, head to the repair shop promptly to avoid long-term wear on engine components. Don't skimp by using cheap oil; sticking to the manufacturer-recommended grade works much better.
