Scratches that expose the primer on a vehicle can be repaired. However, it is advisable to take the car to a scratch repair shop as soon as possible to prevent rusting and corrosion of the surrounding paint. Below are detailed solutions for different types of scratches: 1. Minor Scratches: For minor scratches, polishing can restore the shine of the paint. Use a polishing wheel along with a polishing compound to remove debris and oxidation from the paint, smoothing out the fine scratches. The compound will also penetrate the paint, restoring its original luster. 2. Deeper Scratches: For deeper scratches, check if the metal surface is exposed. If not, rust is not a concern, and you can carefully apply touch-up paint using a fine brush, allowing it to dry completely. 3. Deep and Narrow Scratches: For deep, narrow scratches, colored putty can be used for effective repair. Gently sand the scratched area without enlarging it, ensuring it is clean before applying the putty. Carefully fill the scratch with putty, making sure it adheres well, then apply a finishing compound and wax. 4. Primer-Exposing Scratches: If the scratch has exposed the primer, visit a scratch repair shop immediately to prevent rust and further damage to the surrounding paint.

What Causes Car Jerking at Low Speed but Normal at High Speed?

Car jerking at low speed but normal at high speed reasons: Engine oil passage blockage: First, attention should be focused on the engine. If the car experiences jerking while driving, the engine is certainly involved. The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is also the power source of the engine. If the air intake decreases, ignition weakens, or fuel injection reduces, the power will be insufficient, resulting in a jerking sensation. Transmission oil contamination causing solenoid valve damage: If sludge in the transmission oil circulates within the transmission and blocks the oil passages in the valve body, jerking issues will arise. Over time, this can lead to a series of transmission problems such as overheating, impact, and slipping.

What are the symptoms of too small valve clearance?

Symptoms of too small valve clearance: The valve components will expand due to heat, causing valve leakage and burning of the valve seat. For deformed or burned valve seats, they must be corrected by reaming and grinding, and cannot be repaired solely by lapping with the valve. Valve seats that cannot be repaired should be replaced with new ones. The repaired or replaced seat must be coaxial with the guide hole, with a coaxiality error of less than 0.03 mm. When the engine is running, the valve will expand due to the increase in temperature. If there is no clearance or too little clearance between the valve and its transmission components in the cold state, the thermal expansion of the valve and its transmission components in the hot state will inevitably cause the valve to not close tightly, resulting in air leakage during the compression and power strokes, thereby reducing power. In severe cases, it may even be difficult to start. To eliminate this phenomenon, a certain clearance is usually left between the valve and its transmission mechanism during cold assembly of the engine to compensate for the expansion of the valve after heating.
