Transmission oil leakage can be caused by aging and deformation of oil seals, damage to the joint surface of the transmission case, etc. The specific reasons are as follows: Aging and deformation of oil seals: If the oil seal spring falls off or the oil seal is installed in the wrong direction, the oil seal will lose its oil-blocking function. In such cases, the aged and deformed oil seal should be replaced, and attention should be paid to the installation direction of the oil seal. The side with the spring coil should face the side with oil. Damage to the joint surface of the transmission case: An appropriately thicker paper gasket should be added at the damaged area. If oil leakage persists, welding repair should be performed. Damage to the front joint surface of the bearing: Or loose fastening screws and a blocked transmission vent hole. When the transmission is operating, it is isolated from the external atmosphere, causing an increase in internal pressure, which also leads to oil seeping from the blocked area.

How many types of engines are there?

There are many classification methods for automotive engines, and different types can be categorized based on different criteria. Below is relevant information: Classification by intake system: Automotive engines can be divided into naturally aspirated (non-turbocharged) engines and forced induction (turbocharged) engines based on whether the intake system uses a turbocharging method. Gasoline engines commonly use naturally aspirated systems; diesel engines often employ turbocharging to increase power. Classification by cylinder arrangement: Automotive engines can be categorized into inline and V-type based on different cylinder arrangements. In inline engines, all cylinders are arranged in a single row, usually vertically, but sometimes tilted or even horizontally to reduce height. V-type engines arrange the cylinders in two rows with an angle between them.

Can gasoline with a small amount of water still be used?

Gasoline with a small amount of water can still be used. Here are the specific symptoms of using gasoline with high water content: 1. Engine shaking: If the water content in gasoline is too high, the water will be transported from the fuel pipeline to the cylinders, preventing the gasoline from fully burning. This will increase engine carbon deposits, leading to abnormal engine shaking. 2. Weak acceleration: Incomplete fuel combustion will directly affect the car's power, resulting in weak acceleration. 3. Engine knocking: Long-term use of gasoline with high water content can cause engine knocking and cylinder knocking. 4. Clogged fuel lines: High water content in gasoline can cause rust on the inner walls of the fuel tank and produce other impurities, leading to rust on related components and causing the car to stall. In severe cases, it may even prevent the car from starting.

Does Parking on a Slope Overnight Have Any Impact?

If the slope angle is not significant, parking on a slope overnight has minimal impact. Below are the effects of long-term parking on a slope on a car: 1. Frame deformation: The manufacturing tolerances for the car body are very strict. Parking on a slope causes the entire body to tilt, leading to uneven force distribution and deformation. Over time, this can result in irreversible deformation of the frame, which may even affect the normal operation of the car doors. 2. Suspension system damage: Including shock absorber springs, shock absorbers, and anti-roll bars. When a car is parked on a slope, except for the shock absorbers not being in operation, the shock absorber springs and anti-roll bars remain under tension. Long-term parking on a slope can cause uneven fatigue on one side of the springs, leading to reduced performance and lifespan. 3. Tire wear: Tires bear the entire weight of the car. Parking on a slope causes uneven force distribution on the tires, leading to deformation or uneven wear.
