As we all know there are multiple ways to look for vacuum leaks; you can spray carb cleaner on everything (and possibly start a fire), listen for hissing with a stethoscope or get a smoke machine $$$, or there are some numbskulls on youtube who recommend using cigar smoke. I have found a better way and that is a "Vape" machine. For once I will recommend NOT using canibus for this operation because of the high probability of forgetting what you are doing, however a mint flavored non nicotine mixture can be quite useful (for once). The "Vape" stays "smokie" longer than smoke and is more dense-or denser than smoke making leaks easier to see. I recently had one of the girls from my office help me with this and I'm sorry I can not post the video.
