Does a car need to clean the internal oil passages of the engine?
1 Answers
Engine oil passages need to be cleaned. If you haven't finished running the engine at high speeds yet, you can wait until after the first maintenance to do so, and then perform an engine oil passage cleaning during the next maintenance. Additionally, engine cleaning should be done every time you perform maintenance. Below is some additional information: 1. Consequences of not cleaning the engine: If the engine is not cleaned, once it becomes clogged, it will affect the engine's performance. The dirt left on the internal parts of the engine will increase wear and tear on the engine components, leading to insufficient oil pressure, which can cause valve noise and engine sounds, thereby affecting the engine's lifespan. 2. Formation of carbon deposits: Due to the characteristics of electronic engine control, each time the cylinder operates, fuel is injected first before ignition. When the engine is turned off, the ignition is immediately cut off, but the fuel injected during this cycle cannot be recovered and instead adheres to the intake valve and combustion chamber walls. The fuel evaporates easily, but the wax and gum substances in the fuel remain. Over time, these substances accumulate and thicken, hardening upon repeated heating and forming carbon deposits.
