What are the symptoms of engine oil passage blockage

[VanAniyah]

Engine oil passage blockage symptoms include increased engine vibration, unstable idle, reduced power, increased fuel consumption, and difficulty starting the vehicle. There are four methods to address engine oil passage blockage: 1. Directly add fuel cleaner to the fuel tank: However, the effect is not long-lasting, and the cleaning is not thorough, suitable for vehicles with relatively low mileage; 2. Use the "drip bottle" method for cleaning: This can simultaneously clean carbon deposits and sediments in both the oil passage and the valves; 3. Use a no-disassembly cleaning machine: Connect the engine's inlet and return oil pipes to the no-disassembly cleaning machine's corresponding pipes using special interfaces to form a loop; 4. Completely dismantle the entire oil passage for thorough cleaning: This method is most suitable for vehicles with over 100,000 kilometers and severe oil passage blockage, offering the best results but requiring the most time and highest technical expertise.
