The engine is a large and complex piece of machinery, and it needs to be kept clean to ensure its performance. Here are some tips on how to clean an engine internally:

  1. Start by removing the cover from the engine. This will allow you to access the engine internals.
  2. Use a mild soap solution to clean the inside of the engine. Be careful not to damage the engine or its components.
  3. Rinse off any excess soap and dry off the engine internals.
  4. Reinstall the cover and start up the engine to test its performance.
