The Honda CRV has a lot of abnormal noise

Common causes are as follows.

1. The valve spring seat is abrasive, grooved, grooved or flange is broken;

2. The valve foot clearance is too large or inconsistent;

3. The valve adjustment screw is worn and deviated, and the pin nut is loose;

4. Caused by the gap between the hydraulic valve lifter and the cam (or valve seat). In most cases, the gap is due to excessive wear and tear of the hydraulic tappet, which causes the oil inside the tappet to be depressurized quickly, and the hydraulic tappet needs to be replaced.

5. The oil level of the crankcase is too high or too low. The engine oil level needs to be checked.

6. The valve guide is worn. The valve guide needs to be calibrated or replaced.

7. The tappet is dirty, and the hydraulic tappet needs to be cleaned.

8. The valve seat or valve cone surface is out of circle. Valves and valve cone surfaces need to be ground.

9. If the viscosity of the engine oil is not selected properly, use a higher viscosity grade of engine oil instead.

10. The oil pressure is low, please check the reason for the low oil pressure.

In many cases, it is not the internal valve body that is damaged, but the stubborn dirt and impurities inside, especially in the internal valve body, the dirt and impurities accumulate to form a blockage, resulting in the inability to effectively adjust the oil pressure, resulting in the occurrence of the problem of stagnation, impact and slippage. At the same time, the problem of high temperature of the gearbox cannot be ignored. According to the Automatic Transmission Repair Association, it is called

More than 90% of all faulty automatic transmissions are caused by overheating. ”

High temperatures can damage the quality and friction characteristics of automatic transmission fluids, increase friction and wear, and transmission noise will follow, as well as sludge (impurities or dirt) will also be generated inside the transmission (e.g. valve body), resulting in transmission setbacks and shocks. If the temperature exceeds 120 °C, the rubber sealing material will begin to harden, eventually leading to leakage and reduced hydraulic pressure. If the temperature is higher, the gearbox starts to slip, which in turn causes the temperature to rise even higher.

Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped.

Therefore, only by removing the stubborn dirt and impurities in the gearbox and effectively controlling the working temperature of the gearbox can the gearbox problem be completely solved and prevent its recurrence. This is also the key to achieving "no dismantling and repairing to solve transmission failures", which can be described in detail.

Summary. Hello, I am your exclusive technician, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions to this voice, focus on checking the following.

1 In the first case, check whether there is any oil leakage in the shock absorption of the vehicle.

2 In the second case, check the shock absorbing upper seat rubber plane bearing.

3 In the third case, check the lower arm. Check to see if there is any damage to this ball head that causes this to have abnormal noise.

4 Fourth, check whether the exhaust pipe has an iron or not, that is, when you go on a bumpy road, the exhaust pipe touches the iron.

The Honda CRV has a tinkling sound when it goes over bumpy sections.

Hello, happy to answer your questions.

The crisp tinkling sound, like the sound of metal colliding, comes and goes when crossing bumpy roads.

Hello, I am your exclusive technician, Qi sleepy, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions to this voice, focus on checking the following 1 The first way, check whether the shock absorption of the vehicle has oil leakage, if there is an oil leakage, this will make a sound 2 The second kind of words, check the shock absorption on the top of the seat rubber He Ziqing plane bearing 3 The third way, check the lower arm. Take a look at whether the ball head is damaged and cause this to have an abnormal sound.4 Fourth, check whether the exhaust pipe has a tie is to take a bumpy road section, and the exhaust pipe touches the iron.5 The fifth kind of Zen grip, check the boom and the balance bushing, you must be a tie, or the above may have problems, I hope it can help you.

The Honda CR-V chassis rumble can be caused by a number of reasons, and here are a few possible causes:

1.Suspension System Issues: The rumbling sound of the chassis can be caused by a problem with the suspension system. For example, the springs or shock absorbers of the suspension system may have worn out or failed, causing the vehicle to rattle when driving or passing over raised or potholes.

2.Brake system problems: Problems with the brake system can also cause chassis noises. For example, brake discs may have worn or deformed, and brake pads may have worn to the point where they need to be replaced.

3.Tire problems: Chassis noises can also be caused by problems with tires. For example, tires may have worn out or have irregular wear that causes the vehicle to rattle while driving.

4.Exhaust System Problems: Problems with the exhaust system can also cause chassis noises. For example, the exhaust pipe may have worn out or become loose, causing a rattle while driving.

If your Honda CR-V has a chassis rumbling sound, it is recommended that you go to a regular car maintenance sock and repair shop as soon as possible for inspection and repair. Through inspection and testing, technicians can determine the cause of the chassis noise and carry out repairs and replacement accordingly. Timely repairs can ensure the safety of the vehicle and avoid more serious damage and higher repair costs.
