What are the reasons for the particularly loud engine noise in the Lavida?
3 Answers
Lavida engine noise is particularly loud for reasons including carbon deposits, poor sound insulation, low coolant temperature, shock absorber noise, or engine knocking and detonation. Carbon deposits: As engine oil becomes thinner with use, carbon deposits accumulate. Thinner oil can lead to oil leakage, causing more carbon deposits and significant power loss. When new oil is added, the engine may not adapt to the oil's viscosity, potentially increasing the RPM and resulting in louder engine noise. It is recommended that owners clean the carbon deposits promptly. Poor sound insulation: If the engine sounds normal from outside but noisy inside the car, it indicates poor vehicle sound insulation. Check the vehicle's sealing strips for signs of aging or improve the sealing effect to reduce noise. Low coolant temperature: When the coolant temperature is too low, issues may arise, and engine noise can increase. It is advisable to check and replace the coolant to avoid further problems. Shock absorber noise: Shock absorber performance can usually be assessed when driving over speed bumps. If there are issues with the shock absorbers, engine noise may become louder. If problems are detected, it is recommended to replace the shock absorbers promptly. Engine knocking and detonation: Knocking occurs when the spark plug ignites the mixture, and the remaining combustible mixture auto-ignites. This creates opposing flame fronts that propagate at high speed, producing sharp knocking sounds and increasing engine noise. Owners should check and replace the spark plugs as needed.
I also encountered unusually loud engine noise when I drove my Lavida before, which was really annoying, especially the deafening sound at high speeds. The most common cause is insufficient engine oil or deteriorated oil quality – inadequate lubrication increases engine friction, producing strange noises. Secondly, worn or loose belts are often to blame; if you hear squeaking sounds, this is likely the issue. Additionally, damaged engine mounts or fasteners can cause increased overall vibration and shaking. Exhaust system leaks or rust can also amplify noise. Even a clogged air filter can restrict airflow, making the engine work harder. If these minor issues aren’t addressed promptly, they may escalate into more serious problems, such as engine overheating or damage. I recommend first checking the oil dipstick yourself and listening for belt noises, then visiting a repair shop as soon as possible for a full diagnosis and part replacements—don’t let it worsen. Regular maintenance during daily driving is crucial to prevent such failures and save on repair costs.
When I notice abnormally high engine noise in my Lavida, it often indicates issues with lubrication or drivetrain components. Low oil level or inferior oil causing lubrication failure can multiply friction sounds; aged and loose belts frequently emit sharp squeals. Cracked engine mount bushings losing their damping effect amplify noise during bumps; exhaust system damage like rusted-through tailpipes creates roaring due to airflow leaks. Ignition system problems such as spark plug carbon buildup or faulty ignition coils may also lead to knocking sounds from incomplete combustion. All these factors require thorough inspection, as persistent noise compromises driving comfort and poses significant safety risks. I recommend starting with simpler solutions like oil and belt replacement first. If unresolved, professional diagnostics are needed to identify deeper causes. Gentle cold starts and regular maintenance can substantially prolong engine lifespan.
