Here are the solutions for chain noise issues: 1. Mechanical components: The main causes of timing chain noise usually include lack of tension in the chain tensioner, stretched timing chain, abnormal wear of the guide chain plate, or abnormal timing sprocket. This involves replacing the faulty mechanical components—whichever part is damaged should be replaced. 2. Lubrication system failure: To prevent excessive chain wear and increased clearance, the system is equipped with an automatic chain tensioner. This tensioner operates based on oil pressure. When the lubrication system malfunctions, abnormal oil pressure can lead to excessive chain clearance and noise. Prompt inspection and repair are necessary to prevent excessive clearance and potential engine damage due to chain skipping. 3. Low oil pressure: Noise caused by low oil pressure is usually more noticeable at idle and reduces when accelerating.

I do a lot of car repairs myself, and the most common causes of chain noise are either a loose chain with a failed tensioner or lack of lubrication causing it to jam. I park the car on level ground, turn off the engine, and open the hood to check the chain's tension. If it wobbles, I adjust the tensioner or replace it. Then, I spray chain-specific lubricant, but not too much to avoid attracting dust. If the chain is severely worn, it needs immediate replacement—otherwise, continued driving could lead to chain breakage and engine failure. I recommend a monthly quick check on the chain's condition. DIY saves a lot of money, but less experienced owners should visit a professional shop for peace of mind—chain issues shouldn’t be delayed.

Last week, I noticed a squeaking noise coming from the engine area while driving, which turned out to be chain noise. I tried fixing it myself: found a safe spot to park, removed the cover to check the chain position; if it was loose, I tightened the tensioning bolt—there are simple video tutorials online. Sprayed some specialized lubricant a few times, and the noise reduced significantly. This kind of job only costs about ten bucks for the spray, saving me two hundred bucks at the repair shop. But if the chain is severely worn and makes no noise, it's useless—time for a replacement. Over time, small issues can turn into big troubles, so handling them early brings peace of mind.

Is it mandatory to have someone in the front passenger seat?

It is not mandatory to have someone in the front passenger seat, but there are situations where it is required: 1. When driving on highways during the probationary period, someone must sit in the front passenger seat to provide guidance; 2. When driving in high-occupancy vehicle (HOV) lanes, someone must occupy the front passenger seat, as these lanes are designated for vehicles carrying multiple passengers; 3. For small and micro passenger vehicles with a seating capacity of 9 or fewer people, the vehicle must carry at least 2 passengers, one of whom must occupy the front passenger seat. However, children under 12 years old are not allowed to sit in the front passenger seat. A car is a non-track vehicle powered by an engine, equipped with four or more wheels, primarily used for transporting people and goods.

Can Scooter Motorcycles Run Long Distances?

Scooter motorcycles can run long distances, but it's not as convenient, and several aspects should be noted: 1. The fuel tank capacity of scooters is generally small, with 4 to 6 liters of fuel typically providing a range of 200 to 300 kilometers. It's essential to monitor the fuel level constantly, as refueling on long trips may not be very convenient. 2. 125cc scooters have low ground clearance and small wheels, making them less convenient when encountering potholes or uneven road surfaces. Scooter motorcycles are continuously variable transmission (CVT) and do not have gears, so naturally, there is no gear display. The starting and acceleration of a scooter motorcycle are entirely controlled by the throttle. After starting, simply twisting the throttle to bring the engine speed to around two thousand to nearly three thousand RPM will allow the scooter to start moving, without the need to engage the clutch or shift gears as with regular motorcycles.

What causes the left side to cross the line during right reverse parking?

The reasons for the left side crossing the line during right reverse parking are: 1. The car body is not straightened before entering the garage, and the steering wheel is returned too late; 2. The reference point is observed too late when entering the garage, causing the car to be off-center. There are two types of reverse parking: left reverse parking and right reverse parking. When reverse parking at the garage entrance, observe the rearview mirror to compare the distance between the rear of the car and the garage corner at the control line of the garage entrance. Generally, a foot-length distance is just right to turn the steering wheel back. Reverse parking involves maneuvering the vehicle to correctly reverse into the garage from both sides. It is a mandatory test item for obtaining a small car driver's license after 2013, mainly assessing the driver's ability to operate the car in a confined space.
