Hey All A buddy and I were shoot'n the sh!t the other night and he told me a story and a half. Appears that a buddy of his was at diesel tech school when they had a cummins diesel explode on them. This is not the "doged" cummins but the semi size cummins. As was explained to him, when the engine was turned off inorder to be worker on, the truck experienced blow by, or suck by I guess, where the compression of the cylinders suck oil up passed the rings from the pan. Normally a diesel is rev limited by the mechanical fuel pump. But, when the engine sucked up the engine oil, the engine was nolonger limited and it reved and reved until all the oil was used. The engine exploded /forums/images/graemlins/eek.gif, sending the flywheel through the roof of the shop. No one hurt, they had plenty of time to leave but apparrently there was no way to stop the engine. /forums/images/graemlins/blush.gif Quite the story huh!!! /forums/images/graemlins/cool.gif anyone have something similar, Confirmation?
