I got loads of these, I'll share another with ya'll.
One day at the ford dealership a truck came in that wouldnt start, after performing several different "tests" I figured the module in the dist was bad. Someone left the ignition ON not me...lol
Soon as I lifted the dist out of the block BOOM! The crankcase was full of raw gas and fumes from trying to crank it and when the dist was lifted with the ignition ON it broke the ground to it and the spark it created ignited all those fumes, my left ear still rings to this day. The explosion balloned the valve covers and the oil pan pretty bad, it was an expensive lesson, but looking back it was still funny I must have looked like one of those cartoon characters whoes bomb went off in their face....lol
