Dropped $210 on a smoke machine and it found a leak in 20 minutes that I chased for a week
Bought one of those cheap EVAP smoke machines off Amazon for $210 after spending 6 hours over two days on a P0455 on a 2011 Silverado. Turned it on, pumped smoke in at the throttle body, and found a cracked intake gasket in about 20 minutes that I never would've caught with carb cleaner. I felt dumb and relieved at the same time. Anyone else using a smoke machine on non-EVAP stuff like vacuum leaks and exhaust, or am I overusing the thing now?

I used to roll my eyes at guys buying smoke machines for home use, figured it was a tool you rented or let the shop handle. Then I watched a buddy find a vacuum leak at the intake boot on his Tacoma in like 5 minutes that three of us had been guessing at with brake cleaner for a whole afternoon. Now I use mine for everything, intake gaskets, vacuum lines, even checked a leaky exhaust flange with it once and it worked great. Two hundred bucks stings up front but it pays for itself the first time you don't throw parts at a problem.
