Shit like this happens once in a great while, but we lost a motor in a BMW today. Thankfully, it wasn't our fault. Thing let loose when we cranked it up to 60 mph on the dyno for the New York State Vehicle Emissions test. Number 5 piston took leave of the connecting rod at 3500 rpm. Yeesh. Man, I've seen and heard motors blow up close at least five hundred times over the past 35 years, and I still never get used to that sickening sound. Totally destroyed two spark plugs when the Number 2 followed a second later. Ripped the valve cover off and found some flotsam and jetsam up there too. Now it's a cast iron and aluminum boat anchor. It's a bitch having to call a customer and tell him that his Bimmer just went bye-bye. Another bitch is that he's Harry's neighbor. It was one of them days.
