What is the fault indicated by blue exhaust from the engine?

Blue smoke from the exhaust pipe indicates that the engine is experiencing an oil burning fault. The following are specific causes of oil burning: Worn valve seals: Over time, valves may wear out or age, and severe cases can affect the sealing performance of the valves, making oil burning more likely to occur. Excessive piston clearance: When a car has been used for a long time, carbon deposits from incomplete combustion may accumulate on the piston rings. If not cleaned for an extended period, this can cause the gap between the piston rings and the cylinder to expand, allowing oil to enter the combustion chamber and resulting in oil burning. In severe cases, this can even lead to engine seizure. Driving habits: Frequent rapid acceleration and prolonged high-speed driving can easily damage the lubricating oil film, leading to poor engine lubrication and wear on certain components, which may also result in oil burning. Excessive oil level: If the oil level is too high and exceeds the maximum mark, the excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form gummy carbon deposits.

Do I need to take the subject one test for a delayed license renewal?

If your driver's license has expired but not for more than one year, you do not need to take the subject one test. You can renew it directly after paying the fine. If it has been expired for more than one year, the license will be canceled. If the cancellation has not exceeded two years, you can apply to restore your driver's license and take the subject one test. Required documents: To renew your driver's license, you need to provide your ID card and a copy, the driver's license, a physical condition certificate, a photo receipt, and other materials. Renewal can be processed in a different location: The driver's license renewal can be processed at a vehicle management office outside the issuing location, meaning you can renew your driver's license anywhere in the country without providing additional proofs such as residence or temporary residence. However, please note that if the license has already expired, it cannot be renewed in a different location, and you must return to the issuing vehicle management office to process it.
