What Causes Valve Noise?

Valve noise is caused by: 1. Gap formation or severe wear in hydraulic lifters; 2. Too high or too low oil level in the crankcase; 3. Dirty lifters; 4. Worn valve spring seats with grooves, and wear between valve stems and guides; 5. Oil being too thin—replace with oil of appropriate viscosity; 6. Oil pressure being too low or too high. The methods to address valve noise are: 1. Remove the cylinder head; 2. Grind the valves, check the spring tension of the valve springs, and readjust the valve clearance. The function of valves is to specifically input air into the engine and expel exhaust gases after combustion. Based on engine structure, they are divided into: intake valves and exhaust valves.

How to Drive an Automatic Transmission Car Down a Long Slope?

To drive an automatic transmission car down a long slope, follow these steps: 1. Brake and slow down in advance at the top of the slope; 2. Shift into L mode to assist with braking and control speed throughout the descent; 3. Upon reaching the bottom of the slope, shift back to D mode and accelerate directly. The gears of an automatic transmission car are: 1. P gear is the parking gear and starting gear; 2. R gear is the reverse gear; 3. N gear is the neutral gear; 4. D gear is the forward gear, also known as the drive gear; 5. S gear is the sport mode; 6. L gear is the low-speed gear. The characteristics of an automatic transmission are: it uses planetary gear mechanisms for shifting, automatically adjusting based on the degree of the accelerator pedal and changes in speed, allowing the driver to control the speed simply by operating the accelerator pedal.

How many liters of coolant are needed for a BMW replacement?

BMW requires 6.5 liters of coolant for a single replacement. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It offers excellent performance features such as preventing freezing in winter, boiling in summer, and inhibiting scale and corrosion year-round. Can different coolants be mixed? Only use the same brand of coolant. Different brands may have varying production formulas, and mixing them could trigger chemical reactions between additives, rendering them ineffective. How to check for low coolant levels: Monitor the coolant warning light on the dashboard. If illuminated, it likely indicates low coolant, though it could also signal excessively high cylinder temperatures. Inspect the coolant reservoir. If the level falls below the minimum mark (MIN), do not continue driving and promptly add coolant. Check the level indicators on the coolant overflow tank. Normal coolant levels should be between the MAX and MIN marks. If the level drops below MIN, it indicates insufficient coolant.

Why Does the Chassis Make a Rattling Noise on Rough Roads?

This issue is mostly caused by the aging of rubber components in the chassis. Rubber parts in the chassis effectively absorb vibrations generated by the suspension during operation. Therefore, if these rubber components are damaged or aged, the vibrations cannot be mitigated, and the noise from the suspension will directly transmit into the cabin, giving the impression of a very loose chassis. During regular maintenance, it's advisable to check the condition of the chassis rubber components. If any cracks are found, they should be replaced as soon as possible. Here are some methods to restore a loose chassis in older vehicles: 1. Replace the shock absorbers. In older vehicles, the lubricating oil inside the shock absorbers is likely depleted, significantly affecting their rebound and compression functions. Replacing the shock absorbers can effectively improve the driving experience. 2. Replace the lower control arm. The ball joint of the lower control arm is the most prone to wear. When the ball joint lacks lubrication for an extended period, the wear becomes severe, leading to excessive play in the lower control arm. 3. Replace the rubber bushings. There are many vibration-damping rubber bushings in the vehicle chassis. If these bushings age or crack, various abnormal noises from the chassis will occur during driving.
