I want to find out if the vacuum system is without leaks. I know that on most cars a smoke test can be done to find leaks. Is it possible to perform a smoke test on the whole 2.3 milenia system? If so how..i.e. where do you hook the tester to?

 

A smoker Is used to find leaks in the fuel vapor system normally. It screws onto the gas filler neck where the gas cap goes. It pressurizes the tank and vapor recovery system and you just look for smoke from the lines etc.To find vac leaks on your engine a flammable carb spray is the tool of choice by most. Just spray it on areas you wish to check with the engine idling and if there is a leak the engine will suck the spray in at that point and the idle will change.
