Engine cylinder scoring treatment method: Replace the cylinder block and piston. Engine cylinder scoring is a very serious engine failure, referring to deep grooves being scratched on the inner wall of the cylinder, causing the piston, piston rings, and cylinder wall to lose their sealing ability due to friction. This results in reduced cylinder compression pressure and loss of power. If the symptoms of cylinder scoring continue to be used, the condition will only worsen. Causes of engine cylinder scoring failure: 1. Engine cooling system leaks or lacks water, failing to replenish in time, leading to engine overheating; 2. Engine oil level is too low, causing loss of cylinder sealing and lubrication function; 3. Piston ring breaks, scratching the cylinder wall; 4. Piston pin retaining ring falls off, scratching the cylinder wall; 5. Use of inferior fuel; 6. Piston pin protrudes, scratching the cylinder wall; 7. Foreign objects enter the cylinder; 8. The fit clearance between the piston and cylinder wall is too small; 9. Piston pin assembly is too tight, causing piston deformation; 10. Engine operates at high speed or under overload for a long time; 11. Severe thermal deformation or melting of the piston top.

What to Do About Odor Inside the Car After Window Tinting?

After window tinting, if there is an odor inside the car, you should frequently open the car doors to ventilate. Below are some related tips about window tinting: 1. Precautions for window tinting: When tinting, always choose high-quality film and go to a professional shop for installation. Low-quality films may not meet light transmittance standards, which can affect the driver's visibility during nighttime driving. It is not recommended to tint the front windshield as it may impair the driver's view. When tinting the side windows of the driver and front passenger seats, cut out two sections to ensure the driver can clearly see the side mirrors. After tinting, avoid rolling the windows up and down as this may cause the film to peel off. 2. Duration of window tinting: Generally, car window tinting can last about three years. After removing the film, there may be a lot of adhesive residue on the glass. Before removing the adhesive, it must be softened to ensure easy removal. If you scrape the adhesive without softening it first, it may leave scratches on the glass. After softening the adhesive with alcohol or essential balm, use a plastic scraper to remove it, and avoid using hard metal tools to scrape the adhesive.

Why does the old Passat have a strong smell in the cabin?

If the old Passat has a strong smell in the cabin, it is recommended to check whether the car's air filter needs to be replaced. Delayed replacement of the air filter may lead to strong odors inside the car. There are many reasons for the heavy smell of exhaust in the cabin of an old car. It could be that with the windows closed, the external air circulation is turned on, causing exhaust fumes to enter the cabin. There might also be a leak in the engine's emission system. Additional information: If the car is equipped with an exhaust gas recirculation system, it could be due to abnormal operation of this system. Another possibility is poor sealing of the car's weatherstripping, or engine operational faults that require related inspections.

What are the tire brands starting with the letter G?

There are two types of tires starting with the letter G, namely Giti Tires and Goodyear Tires. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are rubber products and will age over time with prolonged use. It is recommended that car owners replace their tires every four years, even if the mileage is low within those four years. Since tires can also age when left unused for extended periods, it is important to check the production date when purchasing new tires.
