What is the abnormal sound of Buick Hideo valve jumping?

Generally, there will be a clicking sound at the valve or injector of Pacific Auto Network, and the solenoid valve of carbon canister will also have this sound, but the sound is brittle. Inferior engine oil, long-term failure to change engine oil, insufficient engine oil, etc. , it will easily lead to the increase of friction between the valve and the guide tube and the hydraulic tappet, thus making all kinds of sounds in the engine louder.

The general reasons for Buick Hideo's idling jitter and abnormal noise are that the throttle valve is too dirty or the fuel injector has too much carbon deposit. In addition, check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor spark plug misfire can also lead to such failures. The solution is to check whether there is too much carbon in the spark plug and replace the spark plug.

If you clean up the engine carbon deposit, clean the throttle, change the oil pad and spark plug, etc. You still find the car body shaking at idle speed. It is recommended to go to 4S shop to check whether the fuel supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal, or the intake pressure sensor has an incorrect value or works poorly, it will cause the body to shake.

The abnormal sound of Buick Hideo's driving door is mainly caused by the lock buckle. This is indeed a common problem and can be solved by adding butter. Other abnormal noises may also be the aging and hardening of the door sealant. Due to long-term use, the sealing strip will harden and lose its soft elasticity, so it will rub and squeeze each other when closing the door, resulting in abnormal noise, and the car will make a noise when it shakes slightly. At this point, it may be necessary to replace the sealing strip. If the parts or buckles in the door are loose, the door can only be disassembled for inspection, and the problem of abnormal sound can be solved by reinforcement.
