What to Do When the Car Engine Is Too Noisy?

Methods to address excessive car engine noise: Check the oil pump, cooling system, and exhaust pipe for cracks; adjust the valves; inspect oil pressure; examine the muffler and exhaust pipe for damage; recommend changing the engine oil and oil filter, and cleaning the engine. Reasons for excessive car engine noise: 1. Excessive carbon buildup in the engine; 2. Inappropriate or dirty engine oil. The car engine is the device that provides power to the car, serving as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.
The loud engine noise is really giving me a headache. As someone who drives frequently, I believe the issue mostly stems from daily maintenance. The most common causes are oil that hasn't been changed for too long or insufficient oil level, leading to poor lubrication and increased friction noise. Another possibility could be an exhaust system leak - once there's a hole in the pipe, the exhaust noise becomes very noticeable. Or it might be a loose belt slipping and making squeaky sounds. I suggest starting with a self-check: after parking, open the hood and listen for the source of the noise. Different sounds indicate different problems: a tapping noise might indicate oil issues, while a hissing sound could point to belt problems. If the oil level is low or dirty, just buy the right type of oil and replace it. Don't delay too long, otherwise problems like bearing wear will worsen and become more expensive to fix. Personally, I change my oil every 5,000 kilometers, which prevents about 80% of noise-related issues - it saves both money and hassle.
