What Causes Oil Leakage from the Cylinder Head of a Car Engine?

Oil leakage from the cylinder head of a car engine may be caused by a leaking valve cover gasket, oil leakage at the engine timing cover, a loose or damaged oil drain plug at the oil pan, poor sealing due to a long-unreplaced drain plug gasket, a leaking oil filter, oil leakage from the engine oil pan, or a leaking crankshaft oil seal. Below are methods to address oil leakage between the cylinder head and cylinder block: 1. Valve cover leakage. If the leakage is due to poor sealing of the valve cover, the valve cover gasket needs to be replaced. 2. Oil leakage at the engine timing cover. Remove the engine timing cover and reapply sealant. 3. Loose or damaged oil drain plug at the oil pan. Tighten or replace the drain plug. 4. Poor sealing due to a long-unreplaced drain plug gasket. Replace the gasket, and it is recommended to replace this gasket regularly according to the maintenance cycle. 5. Oil filter leakage. If the oil filter is installed too loosely or too tightly, or if a low-quality oil filter is used, replace it with a new one. 6. Oil leakage from the engine oil pan or cylinder block cracking. If the oil pan gasket is aged, remove the oil pan, replace the gasket, and reapply sealant. 7. Crankshaft oil seal leakage. Replace the crankshaft oil seal.

How to Determine Whether a Car is China 5 or China 6 Emission Standard?

Methods to check whether a car is China 5 or China 6 emission standard: 1. Search online. Search for "Motor Vehicle Environmental Protection Website" online, and after entering the website, there is a prominent "New Vehicle Compliance" section. Enter the vehicle identification number (VIN) of the car you want to check, then click the search button to find out the specific emission standard of the new car. The VIN is usually the chassis number or engine number. 2. Check the information on the vehicle's conformity certificate. When picking up the car, the dealer should provide the conformity certificate for the vehicle. For example, the specific standard number for China 5 is "GB18352.5-2013 China V", where China V represents China 5 standard, and China VI represents China 6 standard.

Do I Need to Press the Brake When Shifting from N to D While Stationary?

When shifting from N (Neutral) to D (Drive) while the vehicle is stationary, it is necessary to press the brake pedal. Here are some additional details: 1. If the brake pedal is not pressed, the car would immediately start moving forward after shifting from N to D, which is unsafe. Therefore, car manufacturers have added a safety feature that only allows shifting from N to D when the brake pedal is pressed. 2. Automatic transmission vehicles have both N and D gears. N stands for Neutral, while D stands for Drive. The D gear is the most frequently used gear in automatic cars, as it is required whenever the vehicle moves forward. The Neutral gear can be used when the car is parked.

What is the Difference Between National 4 and National 5?

National 4 and National 5 differ in the upper limit of sulfur content: 1. The upper limit of sulfur content in National 4 standard gasoline is 10mg; 2. The upper limit of sulfur content in National 5 standard gasoline is 50mg. Additional information: 1. National 5 has stricter control over nitrogen oxides compared to National 4, with National 5 setting the emission limit at 25%. 2. The National 4 emission standard is the fourth stage of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. The application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices helps reduce these emissions.

How to Replace Summer Windshield Washer Fluid with Winter One?

Windshield washer fluid replacement method in winter: 1. If it's the same brand of washer fluid, there's no need to drain the summer fluid - you can directly add winter fluid as they can be mixed. If using different brands, first completely drain the summer fluid before pouring in winter fluid. Different brands contain different ingredients that may react chemically, forming sediments that could clog the nozzles and eventually prevent spraying completely. 2. To add winter fluid, open the engine hood, locate the filler cap with washer symbol, open it and pour in the fluid until reaching the marked level (there's a dipstick inside the reservoir). 3. Don't forget rear wipers if equipped. The long tubing between rear wiper and reservoir may retain summer fluid which could freeze if not properly drained during replacement.

How to adjust the headlight height of Wuling Hongguang S?

The steps to adjust the headlight height of Wuling Hongguang S are as follows: 1. There are corresponding adjustment screw knobs at the rear of the headlights. 2. Open the front hood, locate the headlights on both sides, and you will see two hexagonal recesses on the surface of the headlights, one for low beam and one for high beam adjustment. 3. Find a dark place and use a cross screwdriver to slowly turn the screws until the appropriate height is achieved. Method for adjusting the headlight height of Wuling Hongguang S: 1. First, park the car 7.6 meters away from a wall, then turn on the lights. The light projection position will be adjusted based on the position of the lights on the wall. For models with a manual headlight height adjustment switch, set the adjustment knob to the '0' position before adjusting the headlights. 2. To set these standard lines on the wall, first measure the following three distances of the car's headlight position: Distance A is the distance from the center of the low beam to the car's central axis; Distance B is the distance from the center of the high beam to the car's central axis; Distance C is the distance from the center of the low beam to the ground. 3. Before adjusting, project the headlights onto the wall and observe if the lights are misaligned, too high, or too low.
