Turbocharger oil leaks can be repaired. Causes of oil leakage: 1. Loose oil inlet pipe connection on the turbocharger; 2. Excessive clearance between the rotor shaft and bushing; 3. Low turbocharger speed due to insufficient engine power; 4. High turbocharger speed leading to increased pressure ratio, causing rough engine operation. Solutions: 1. Replace engine oil and clean or replace the oil filter; 2. Tighten the connections to prevent seepage; 3. Replace the spring if the exhaust blow-off valve spring fails; 4. Replace silicone rubber hoses. Turbocharger oil leaks occur because the rubber sealing rings inside the transmission lose a significant amount of plasticizers and softeners due to prolonged exposure to alternating hot and cold temperatures, leading to corrosion, aging, and hardening problems.

Why is the license plate registration at 4S stores so slow?

4S stores' slow license plate registration can be expedited by urging them to complete the procedures as soon as possible. Alternatively, car owners can choose to handle the license plate registration procedures themselves at the vehicle management office. Materials required for vehicle license plate registration: 1. Original and photocopy of ID card. If processing on behalf of someone else, both the agent's and the car owner's IDs must be brought. 2. Original and photocopy of the invoice. 3. Original and photocopy of the vehicle qualification certificate. 5. Original and photocopy of the compulsory insurance policy. 6. Tax payment certificate. Relevant information about license plates is as follows: 1. Introduction: License plates, commonly known as vehicle plates, refer to the plates hung on the front and rear of a vehicle, displaying the vehicle's registration number, registration region, or other relevant information. 2. Function: License plates serve as a numbering and information registration system for vehicles. Their main purpose is to identify the region to which the vehicle belongs and to trace the vehicle's owner and registration details based on the license plate number.

When is the best time to take a new car on the highway?

New cars should avoid high-speed driving, long-distance driving, and fully loaded driving. During the break-in period of a new car, the following points should be noted: 1. The first 500 kilometers are the initial break-in period, during which the speed should not be too high. Generally, it is best to stay below 70-80 km/h, with the engine speed not exceeding 2200 rpm. 2. From 500 to 1000 kilometers is the mid-term break-in period, during which the maximum speed can be appropriately increased. Generally, it can reach 90-100 km/h, with the engine speed still best kept below 2500 rpm. Appropriately increasing speed will not affect the engine but can promote the break-in process and help identify any abnormalities during acceleration. 3. From 1000 to 1500 kilometers is the late break-in period, during which the speed can be increased to below 120 km/h. Since the break-in is a gradual process, it must be done step by step. The engine speed should not exceed 3000 rpm.

What Causes the Abnormal Noise When Turning on the AC Button?

Here are the specific reasons for the abnormal noise when turning on the AC button in a car: 1. Contaminated electromagnetic clutch: Due to the electromagnetic clutch being located relatively close to the ground, prolonged driving can cause it to accumulate dirt or mud, leading to bearing damage and resulting in abnormal noise. 2. Loose drive belt: The car's air conditioning compressor places high demands on the electromagnetic clutch during operation. A loose drive belt increases the load on the electromagnetic clutch, making it prone to damage and, in severe cases, causing the compressor to burn out. 3. Repeated engagement of the electromagnetic clutch: Frequent engagement of the electromagnetic clutch can lead to insufficient power generation from the alternator, causing the compressor to operate with inadequate voltage and resulting in abnormal noise. 4. Lack of lubricating oil: Insufficient lubricating oil inside the compressor. After prolonged use, it's necessary to add an appropriate amount of lubricating oil to avoid abnormal noise or failure due to friction.

For example, if you first obtained a C1 driver's license and later acquired a D license through an additional driving test, then the driving experience is calculated based on the C1 license. If you first obtained a D license and later added a C1 license, then the driving experience is calculated based on the date of obtaining the D license. In other words, the driving experience is calculated based on the date of whichever type of driver's license was obtained first. C1 Driver's License: The C1 driver's license is one of the codes for motor vehicle driver's licenses. The C1 license allows driving small and micro passenger vehicles, light and micro cargo vehicles, as well as light, small, and micro special-purpose vehicles; small passenger vehicles with a seating capacity of 9 or fewer people.
