The guy who lived about half a block away from our apartment on Okinawa really liked to warm up his small block Chevy engine every morning at around 6:00 AM by revving it up repeatedly for several minutes. His pipes would rattle windows. Several young children in the neighborhood, including my newborn daughter, were not impressed. A few friendly hints, and then some not-so-friendly ones, were ignored. That engine got really quiet when somebody poured a bottle of Karo syrup into the crankcase!
