The leak check of the exhaust system shall be performed as follows:
-Start the engine and close the silencer with a rag.
-In the case of a gas leak system, if necessary, bubbles can be processed by a special leak detection system-if a leak is present.
-In the event of detection of a non-hermetic section, it is necessary to remove it.
It is desirable to remove the leak in the shortest possible time, since it could lead to complications at the start of the engine, the vibrations of the engine at idle, and the ropes when the engine turns off, as well as other problems.
