Should a Slightly Blown Cylinder Head Gasket Be Replaced?

A slightly blown cylinder head gasket should be replaced. Because after the cylinder head gasket is blown, it is very likely that water will enter the engine oil, indicating that the gasket has failed. This requires immediate replacement, otherwise excessive temperature may cause cylinder scoring and lead to severe engine damage. The symptoms of a blown cylinder head gasket are: 1. Decreased engine power, resulting in poor vehicle performance; 2. Abnormal high engine temperature and poor operation; 3. Reduced coolant level, presence of engine oil in the coolant, or water in the engine oil. More information about cylinder head gasket failure is as follows: 1. Cylinder head gasket failure refers to an impact-type fault occurring between the engine's piston and the cylinder liner. 2. Engine cylinder head gasket failure can simply be understood as an impact-type fault occurring between the piston and the cylinder liner or the gasket. Common gasket erosion is caused by high-temperature, high-pressure gas impacting the gasket, burning the sealing edges, protective rings, and asbestos board, leading to cylinder leakage and mixing of lubricating oil and coolant.

Can I schedule the exam if the required hours for Subject 2 are not completed?

You can schedule the exam even if the required hours for Subject 2 are not completed. If you have already made an appointment, you can contact your instructor for further guidance. Here is some additional information: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skills test. For small vehicles (C1/C2), the test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves). Some regions may include a sixth item: high-speed 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, crossing a single-plank bridge, curve driving, right-angle turns, passing through a limited-width gate, navigating continuous obstacles, driving on undulating roads, narrow road U-turns, simulated highway driving, continuous sharp turns on mountainous roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling.

How long should a car idle to warm up after being parked?

If the car hasn't been driven for over a month, it's advisable to let it idle for warming up, but only for about ten seconds before shifting into gear and driving. If the vehicle has been left unused for an extended period, it's recommended to change the engine oil before using it again. Engine oil left in the oil pan for a long time can oxidize and deteriorate. Continuing to use the car without changing the oil can accelerate engine wear. More details are as follows: 1. Many car owners have the habit of idling to warm up the car, which is actually not a good practice. Idling only increases fuel consumption and exhaust emissions. 2. For fuel-injected engines, idling to warm up is completely unnecessary. The correct way is to start the engine, shift into gear, and drive immediately, just avoid running the engine at excessively high RPMs at the beginning. 3. Shifting into gear and driving right after starting the engine also helps the transmission oil reach its normal operating temperature quickly, reducing transmission wear. Driving immediately after starting increases the engine load, speeding up the warming process. 4. Regular oil changes are essential in daily car use. Over time, engine oil loses its lubricating properties, and prolonged use without changing can worsen engine wear. Always replace the oil filter with every oil change, and ensure to choose genuine products from reputable brands when purchasing oil filters.

Will points be deducted for shifting to the wrong gear in Subject 2?

No points will be deducted. Subject 2 mainly assesses the candidate's ability to control the vehicle's position on the field. Shifting to the wrong gear generally does not result in point deductions, but if a wrong gear is detected, it is still necessary to promptly shift to the correct gear to avoid affecting the vehicle's performance and, consequently, the operation of the vehicle. Automatic transmissions in cars are divided into: P (Park), R (Reverse), N (Neutral), and D (Drive), with some cars also having an S (Sport) mode. P stands for Park: used when the car is parked. R stands for Reverse: used when the car is reversing. N stands for Neutral: used when the car is stationary. Note that when in Neutral, the brake should be engaged to prevent the car from rolling. D stands for Drive: the most commonly used gear for driving, which automatically shifts based on the driver's throttle input. S mode, like D, is also a driving mode. The difference is that S mode provides stronger power than D mode, allowing for quicker acceleration, hence it is also called Sport mode. S mode is primarily used for overtaking on curves and climbing slopes, as it offers stronger power, making overtaking and climbing easier.

Can You Do Car Painting by Yourself?

Car painting can be done by yourself, follow these steps: 1. First, clean the car body with water, use a sanding block to flatten the sandpaper, then wet sand the scratches until the edges are smooth. 2. Use a spreader to evenly apply putty on the scratched surface and wait for it to dry completely. 3. After drying, wet sand the putty with sandpaper until the putty surface is flush with the paint surface. 4. Mask the surrounding parts of the scratch, and once properly masked, you can start painting. 5. When spraying, maintain a distance of about 20 cm from the object being painted, press the nozzle for even spraying, and multiple coats will yield better results. Additional tips: 1. When applying multiple coats, ensure an interval of at least 10 minutes between coats to allow the paint to dry, preventing runs. If runs occur, wait for them to dry, then sand them smooth and spray from a distance to cover. Once the paint is completely dry, you can apply a clear coat to enhance gloss, protect the paint, and improve durability. 2. For correct spraying, the spray path should be perpendicular to the surface. To achieve a wetter, darker, and thicker coat, spray closer; for a drier, lighter, and thinner coat, spray farther. For uniform thickness, use a cross-spraying method followed by horizontal spraying.
