Years ago (in the early 80s) when I was in the U.S.Coast Guard I stood on the dock and watched a 8V92 inhale itself. It was a high hour used engine in a patrol boat that started to run away. They shut off the fuel so it started using the crankcase oil and kept running away. They closed the flapper and it inhaled it, they shoved rags, towels and anything else they could down the intake. It inhaled everything and kept running away until it finally threw the connecting rods through the block. Made a big noise and a lot of smoke. Glad I was standing on the dock, will never forget seeing that.

That is a cool story
