What's with the loud engine of Honda Accord?

What should I do if the Honda Accord engine is noisy? The noise of Honda Accord engine may be due to the long parking time of the car, and all the lubricating oil of the car flows to the oil pan of the engine. When the automobile is cold started, the oil pressure cannot be established immediately, and the hydraulic tappet and mechanical rocker arm cannot work normally, resulting in abnormal sound. This is a normal phenomenon. When the engine works for a period of time, the engine will return to normal and the abnormal noise will disappear. If the engine belt is not tight enough, the engine will produce abnormal noise. In this case, it is necessary to adjust the tension of the engine belt. In another case, the exhaust gas from the exhaust pipe is blocked, causing the engine to vibrate. The exhaust pipe needs to be checked and replaced in time, and the abnormal sound will disappear. If there is something wrong with the oil, it will affect the engine. If the oil is too viscous and poorly lubricated, friction will not occur. It's time to check the oil.
