What Causes the Loud Engine Noise in the Langdong?
2 Answers
Langdong engine noise is loud at 100,000 kilometers. The explanations for the loud engine noise are as follows: The reasons for the increased engine noise in a car include: Cooling system failure, engine overheating; excessive carbon buildup, resulting in loss of engine power; incorrect oil condition. Six steps for engine maintenance: Lubrication: Primarily to reduce friction between moving parts, minimize wear, and ensure smooth operation. Key tasks include ensuring sufficient lubrication for moving parts and timely replacement or replenishment of lubricants and filters. Cleaning: Prevents corrosion of parts, reduces wear on components, and lowers fuel consumption. Key tasks involve surface care for parts and thorough cleaning of assemblies and components both inside and out. Inspection: Determines the working condition of parts, checking for deformation or damage. Key tasks include examining the surfaces, working conditions, and bolt tightness of various assemblies and components. Tightening: Ensures secure connections between parts and prevents loosening. Focus areas are connections under heavy and frequently changing loads, along with necessary tightening or replacement of bolts. Adjustment: Crucial for the long-term proper functioning of assemblies and components. Key tasks involve restoring normal clearances and working functions between assemblies, components, and parts according to technical requirements. Replenishment: Refers to the addition of fuel, lubricants, and special working fluids during car maintenance.
When I first took over my friend's Elantra, I noticed the engine noise was particularly loud. After researching several possibilities, the most common issues were poor oil condition or incorrect oil type, which can affect lubrication and amplify metal friction sounds. Elantra owners know that its exhaust system gaskets are prone to aging and leaking, producing a puffing sound like a broken bellows. Worn-out spark plugs causing unstable ignition can also make the engine sound abnormal—my car sounded like a tractor when I didn't change the spark plugs at 40,000 km. Aging engine mounts can lead to body resonance, especially noticeable when accelerating. Once, I encountered a lack of lubrication in the belt tensioner pulley, creating an annoying squeaking noise, but it became quiet after replacing it during routine maintenance.
