Engine keeps running
Have 2001 Itasca, 220 caterpillar diesel. When I turn the ignition off, the engine keeps running. Any idea why this is happening. Thanks

Yea Brett, a turbo diesel can lose a turbo seal and "run away". If it's a big enough leak, it will run well beyond max RPM since the gov. is out of the circuit. Either way, unless you plug the intake, it will run until out of "fuel" and seize.
There are countless videos on Youtube of this happening. Pretty entertaining!
Scott,
You are absolutely correct-- a more common issue on the Detroit 2 strokes, but lubricating oil is/can be a "fuel" if a significant leak of the turbo oil seal on the intake side of the turbo. If the leak is massive enough, as you said, it can allow the engine to "run-away".
But the OP did not mention run-away RPM and/or seized engine. Just, "I can't shut it off". Would prefer to direct them to the more common causes, not scare them with the "worst case scenario".
