Checking Intake System Integrity



Checking Intake System Integrity







Leaks in the intake and inlet system can be detected by spraying starter gas in strategic places. If there is a leak, the engine speed will increase slightly when the starter gas enters the system.

Check the following points for leaks:
^ gaskets
^ hoses and hose connections
^ joints
^ throttle body.
