Can the Oil Leakage of Audi Crankshaft Oil Seal Be Ignored?

Crankshaft oil seal leakage should be taken seriously and addressed promptly. Reasons for crankshaft oil seal leakage: It is found that the crankshaft oil seal is misaligned inside the sealing seat, causing the oil seal to tilt relative to the outer circle of the crankshaft; during the installation process, the chamfer angle of the aperture is too large, leading to biting or scratching of the crankshaft oil seal, which results in deformation of the outer diameter of the crankshaft oil seal and the oil seal frame. This can easily cause early-stage oil seal failure, leading to oil seepage or leakage. Introduction to oil seals: Oil seal is a common term for general sealing, simply put, it is the sealing of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in transmission systems, and also generally refers to liquid substances). It isolates the components that need lubrication in the transmission system from the output components, preventing lubricating oil from leaking. Sealing components used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. The representative form of oil seal is the TC oil seal, which is a double-lip oil seal fully covered with rubber and equipped with a self-tightening spring. The commonly referred oil seal often means this TC skeleton oil seal.

What Causes Engine Oil Dilution?

There are three main causes of engine oil dilution: contamination with gasoline or water, engine component issues, and temperature conditions. Below is a detailed explanation of engine oil dilution: 1. Contamination with gasoline or water During vehicle operation, poor piston or cylinder sealing can allow combustion gases to enter the crankcase. When temperatures drop, these gases condense into liquid and flow back into the oil pan, increasing oil volume while introducing water contamination. Additionally, incomplete fuel combustion in cylinders can cause unburned fuel to drain into the oil pan, diluting the oil and reducing its protective properties for the engine. 2. Engine component issues Oil dilution may relate to engine component problems such as insufficient cylinder pressure or poor cylinder sealing, which reduce engine power and make starting difficult. Faulty fuel injectors causing dripping or excessive fuel injection require professional diagnosis and repair by mechanics. 3. Temperature conditions During cold starts, the engine requires richer fuel mixtures, causing injectors to spray more gasoline. Excess fuel can then drain back into the oil pan. Generally, the primary cause of oil dilution is excessive fuel injection.

Is Borgward a Domestic or Joint Venture Brand?

Currently, Borgward is considered a domestic brand in China. Here is some extended information: 1. The origin of Borgward: Borgward (BORGWARD) was founded in Bremen, Germany in 1919 by German engineer Carl Borgward. By the 1950s, Borgward had reached its peak, with annual sales exceeding 1 million units, rivaling Audi and BMW. However, in 1961, Borgward suddenly faced financial difficulties, and its arrogant attitude left banks unwilling to assist, ultimately leading to bankruptcy. It wasn't until 2015 that Borgward made a sudden comeback. 2. The return of Borgward: Borgward's revival was primarily due to its acquisition by China's Foton Motor. Under Foton's ownership, Borgward established its global headquarters in Stuttgart, Germany, and set up technology research centers in Silicon Valley, USA, and Beijing, China. After its revival, Borgward first launched the BX7 SUV in the Chinese market, followed by models such as the BX5, BX6, and BX7 SUVs.

How many kilometers should power steering fluid be changed?

Power steering fluid should be replaced every 40,000-50,000 kilometers or within 2-3 years. Method for changing power steering fluid: When changing the fluid, air needs to be purged from the system during refilling or if air gets mixed into the steering system. The bleeding procedure is as follows: First fill the fluid to the specified level in the reservoir, then start the engine and lift the front axle. With the engine idling, remove the drain plug at the bottom of the steering gear. Turn the steering wheel fully left and right several times, repeating this process while continuously topping up the reservoir. Simultaneously, loosen the system's bleed screw until the fluid fills the entire system with no air bubbles emerging from the bleed port, and the reservoir level stabilizes. Finally, tighten the bleed screw. Precautions for changing power steering fluid: Do not operate the power steering pump for extended periods as this may damage the pump. Never use transmission fluid as a substitute for power steering fluid - these fluids have different viscosities, molecular structures, and functions.

What does the 'sport' display on Corolla mean?

The 'sport' on the Corolla's transmission, located on the gear shift lever, indicates the sport mode. Selecting this mode will delay gear shifting. For example, where the transmission would normally shift at 2000 RPM, in SPORT mode it might shift at 3000 RPM. This makes the engine more aggressive, providing a stronger sense of acceleration (commonly referred to as 'push-back feeling'). Below is some related information: 1. Corolla: The biggest advantages of Corolla's design are its low fuel consumption, comfortable ride with smooth driving experience, and rich humanized interior configurations. As the best-selling family car, it boasts 40 million users worldwide, offering excellent quality and peace of mind. 2. Power: The overall power performance is good with quick acceleration, though the initial start is somewhat slow. The engine noise is minimal, described by users as very quiet with little sound inside the cabin. However, when driving over 80 kilometers per hour, the tire noise becomes more noticeable, leading some owners to modify their cars for better sound insulation.

What should be paid attention to when driving a car in a tunnel?

The following are precautions for driving through a tunnel: 1. Slow down as required before entering the tunnel, and turn on the headlights, width lights, and taillights; 2. Choose a lane before entering the tunnel, maintain sufficient distance, and do not change lanes at will; 3. Do not turn on the high beams, as it may easily cause danger; 4. Do not park randomly in the tunnel. In case of an emergency, the owner must try to park the car at a special parking spot, turn on the hazard warning lights, and call the police. Extended content: Precautions for using car lights when entering a tunnel are: 1. Turn on the low beams when driving at night; 2. When the rear car is driving close to the front car in the same direction, do not use the high beams; 3. When passing sharp turns, slopes, arch bridges, crosswalks, or intersections without traffic lights at night, alternate between high and low beams to signal.
