Hello, I broke the oil plug of my Vespa gts 250. Now the oil is not leaking thanks to the liquid seal. But instead of using the liquid seal every year, I want to do helecoil. But isn't the work in the video a little dirty? What should I do to prevent a piece of metal from getting into the tank? If that small piece of metal gets into the oil sump tank, won't it be a problem?Last Minute I'm not talking about the salvaged piece. Won't the metal pieces formed when drilling a hole with the drill at the beginning of the video escape?
