I was just cruising around town yesterday about 20 mins after leaving my house i was leaving a stop light and at 20 mph i hear a BOOM clank clank:doh: I thought i was my drive shaft but when i looked down and the engine had shut off i knew something else was wrong. Stopped the truck and looked underneath and there was oil covering driver side of block. I had felt the truck vibrating pretty noticably that day just didnt pay too much attention. Needless to say the truck wont crank now, im pretty bummed out. Tech seems to think i broke a rod. Im glad it happened to me though, i had it for sale i would have hated to sell it to someone and it break the next day!
