While on a family trip, Mike started the engine and his daughter’s blouse got sucked in through the exhaust. The car still runs, but he has no idea how this happened. Ray tries to explain it as piston overlap--slight period at end of piston downstroke when exhaust is still open. But, is that big enough to suck in a blouse? Tom and Ray say they’ll look for answers from experts on the site.
