How to Smoke Out a Vacuum Leak
Using a smoke machine to reveal leaks in the carburetor, hoses, gaskets, etc. I see a lot of smoke coming from the valve cover. At first I thought it was an internal vacuum leak, but it was just smoke leaking past the valve guides and seals into the crankcase. This was verified in my video, "Checking for an Internal Vacuum Leak".
