What Causes Motorcycle Engine Oil Leakage?

Motorcycle engine oil leakage may be caused by improper installation of the oil filter or leakage from the engine's sealing gasket. Related information: Engine oil is crucial for the engine, often referred to as the lifeblood of the engine. Without engine oil, the engine cannot operate normally. Function of engine oil: Inside the engine, engine oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, engine oil forms a thin film on the surfaces of various components inside the engine, preventing direct contact and friction between them. If engine components directly contact and cause friction, it can accelerate engine wear and may also lead to the sudden generation of a large amount of heat inside the engine, which is a fatal issue for the engine.

I've encountered motorcycle oil leaks several times, with common causes including aging or damaged oil seals. For example, the crankshaft oil seal tends to crack and leak over time. Additionally, loose oil caps or screws can allow oil to slowly seep out, especially noticeable when riding on bumpy roads. Improper installation of the oil filter can also lead to an unsealed gasket, causing oil to spray when accelerating. Aging pipes or damage from foreign objects are potential issues too—once after a ride, I found oil stains under the engine, only to discover a mouse had chewed a hole in an oil pipe. More seriously, internal engine wear or damaged gaskets can cause gradual oil loss. If not repaired promptly, it can affect engine lifespan or even lead to a breakdown mid-ride. I recommend checking the oil level every few hundred kilometers. If an oil leak is detected, visit a professional shop for diagnosis to prevent minor issues from becoming major problems.

Should Minor Scratches on a New Car Be Polished?

Scratches can indeed be removed through polishing. Polishing involves the high-speed rotation of a polishing wheel, which can grind away the oxidized layer and dirt on the car's paint surface, effectively eliminating minor scratches. However, it's important to note the frequency of polishing. Frequent polishing can, to some extent, damage the car's paint. As the paint is continuously ground down, it becomes thinner, reducing the car's ability to maintain itself. Below is additional information on scratch polishing: 1. If a new car develops scratches, polishing is an option, especially for minor scratches. The paint can still withstand it. However, it's recommended to use wax instead, specifically abrasive wax. The special grinding particles in abrasive wax can also remove scratches, and compared to polishing, waxing is less likely to harm the new car's paint and is a more reassuring option. 2. If the scratches are deep and reach the primer or metal layer, the paint should first be repaired. After the paint has fully hardened, a detailed polishing process can be performed. New car paint is of high quality and less prone to oxidation, so regular maintenance is sufficient, and polishing isn't necessary. For older cars, typically after 3-5 years when the paint begins to age, polishing can help restore the paint's shine.

What Actions Can Cause Engine Stalling?

The following actions can cause engine stalling: 1. Using low-quality fuel; some gas stations sell impure fuel for excessive profits, and some car owners cannot resist the temptation of low prices and purchase inferior fuel. Over time, this leads to excessive carbon buildup in the engine, making the car very prone to stalling. 2. Clogged fuel lines: Blocked fuel lines are another reason for sudden engine stalling while driving. One cause of clogged fuel lines is the use of substandard fuel with too much gum and resin, which blocks the fuel lines and disrupts fuel supply. 3. Insufficient driving skills: Lack of driving proficiency is also a significant cause of engine stalling, though this issue generally occurs with novice drivers and rarely affects experienced drivers.
