Vacuum Leak Test with Cigar?

[robw13]

Hi,

Has anyone tried testing for Vacuum Leaks with a Cigar? Would propane, water or wd40 work better? If propane, do u use a hose with it or just by itself?

Found the reason why my AC had such high pressures and wasn't cooling with cig smoke . Flammable brake clean works pretty well in finding vac leaks. It's thin enough to get into the smallest leaks.....
