Ennjunz, this is getting way off topic, but the N14 broke a shaft in the turbo, which is not commons, but it happens when you log several million miles a year. Although the driver had been driving a truck for over 20 years, he had never heard of a runaway. With a broken shaft the turbo sprayed oil into the intake and that created the runaway. With all the smoke, the driver thought something was on fire and called the fire department instead of putting it in Hi gear and dumping the clutch. The engine ran until it was out of oil, the No.1 spun, the rod stretched and the piston hit he head. They say bad luck runs in 3's. We actually blew 3 turbos in 2013 and they all were Cummins Recon. Not some of the Chinese aftermarket that are around now.
