Valve cover gasket oil leakage will produce pungent oil smoke in the car engine, and direct oil dripping onto the road will cause environmental pollution and cleaning difficulties. The following is a detailed introduction to the causes of automobile valve cover gasket oil leakage: 1. The valve cover gasket functions to seal and prevent oil leakage, and the sealing gasket is mostly made of rubber material; 2.

What are the test items for Subject 2 in Beijing?

For small vehicles (C1, C2), the test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope (canceled for C2), right-angle turns, and curve driving (commonly known as S-curve). Some regions also include a sixth item: highway toll card collection. For large vehicles (A1, A2, A3, B1, B2), the test items include: stake test, stopping and starting on a slope, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, passing through a width-restricted gate, navigating continuous obstacles, driving on bumpy roads, narrow-road U-turns, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required. ② For other vehicle types, a score of 80 or above is required. Candidates who fail the Subject 2 test on their first attempt are allowed one retake. If the retake is not attended or is failed, the test process ends, and the applicant must reschedule the test after ten days. Within the validity period of the driving skills test permit, the number of rescheduling attempts for Subject 2 and Subject 3 road driving skills tests must not exceed five. If the fifth attempt is still unsuccessful, the results of other previously passed subjects will be invalidated.

How Long After Passing C1 Subject 1 Can You Take Subject 2?

For a C1 driver's license, you can schedule the Subject 2 test online 10 days after passing Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the registration requirements for Subject 2 include completing 26 study hours: 2 hours of theoretical knowledge, 3 hours of simulated driving, and 21 hours of practical training. For a C1 driver's license, you can schedule the Subject 2 test online 10 days after passing Subject 1. Each Subject 2 test appointment allows for two attempts. If the first attempt is unsuccessful, you can retake the test for free once. If you do not attend the retest or fail the retest, the test session ends, and you can reschedule Subject 2 after 10 days. Within the validity period of the driver's learning permit, the number of Subject 2 test appointments must not exceed five. If the fifth attempt is still unsuccessful, the results of other previously passed subjects will be invalidated. To continue pursuing the driver's license, you must restart the process from Subject 1. Subject 2 test content includes: driving a motor vehicle to complete test items within a designated area; demonstrating mastery of driving skills; and assessing the ability to judge the spatial position of the vehicle. Subject 2 is also known as the small road test and includes five mandatory items: reverse parking, parallel parking, hill start and stop, right-angle turns, and curve driving. Subject 2 test precautions: After getting into the car, always adjust the seat and mirrors to a suitable position and state, and ensure the seatbelt is fastened. For parallel parking, remember to find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. For hill starts, remember to engage the handbrake, activate the left turn signal when starting, release the handbrake, stabilize the clutch, and gradually release the clutch while pressing the accelerator to avoid stalling or rolling back. For right-angle turns, identify the turning point quickly and react accordingly, coordinating with the car's speed to prevent deviation. For curve driving (S-turns), slow down and proceed cautiously. Those with good driving instincts during practice may pass smoothly in one go. For reverse parking, control the speed carefully, identify reference points accurately, and make minor adjustments when observing deviations in the mirrors. The driver's license test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers traffic safety laws, regulations, and related knowledge. Subject 2 is the field driving skills test. Subject 3 is divided into two parts: road driving skills and safety and civilized driving knowledge. The safety and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official terminology (under the Ministry of Public Security's Order No. 123) does not include the term "Subject 4."

What's the reason for not being able to shift into S gear?

Failure to shift into S gear is mainly due to transmission damage. It is recommended to have it inspected and repaired at a 4S shop. Here are some related additional information: 1. S gear: S stands for 'sport'. In sport mode, the car's overall performance is enhanced, and its acceleration capability becomes stronger. Sport mode is often used for overtaking or climbing slopes. After engaging sport mode, the car's gear will drop quickly, with a certain delay in shifting, allowing the engine to maintain high RPMs for an extended period. 2. Possible fault points: It could be a fault in the clutch system's release bearing, friction disc, or pressure plate. It might also be an issue with the gear shift assembly or the shifting mechanism.

Where to Check the Production Date of Wheel Hubs?

A 4-digit number can be found near the tire close to the wheel hub. The first two digits indicate the production week, and the last two digits represent the production year. For example, 0110 means the wheel hub was produced in the 1st week of 2010 (the last two digits represent the year, and the first two digits represent the week). Below is some relevant information about wheel hubs: 1. Concept: The wheel hub is the rotating part of the wheel steel inside the tire connected by columns to the wheel core, i.e., the metal component that supports the tire and is mounted on the axle. It is also called the rim, steel ring, or wheel. Wheel hubs come in various types based on diameter, width, forming method, and material. 2. Size: The wheel hub size essentially refers to its diameter. Common terms like 15-inch or 16-inch wheel hubs refer to the size (diameter) of the wheel hub. Generally, in passenger cars, larger wheel hub sizes and higher tire aspect ratios can create a visually appealing tension effect and improve vehicle handling stability. However, this also comes with additional issues such as increased fuel consumption.
