The aain main line leak detector's superior materials makes sure that it ages well with use. It is good as a snapon smoker that costs mega bucks. It provides lots of smoke to add to that it is the intake manifold gasket. The unit has a pressure regulator built in to reduce the air pressure but it is more than sufficient to do the job and the original baby oil product recommended is easy and safe to use as a smoke agent.

The swivel hook allows the tool to move with the cords and hoses instead of having them get wrapped around it while working under the hood. It works on.50 lbs pressure so you won't blow out any seals or sensors.

  • 30 minute sessions with the oil still visible in the sight glass
  • Lots of smoke and easy to find the leaks
