Exactly, the motor runs on lubricating oil, it is beyond scary. It
also produces so much smoke, that I would be unable to even enter the
trailer or if I am there, I would have to get the hell out. I will
keep a piece of metal handy to slam shut the intake and I may try to
pipe the intake or exhaust to outside.

i,  Steve knows this engine so confirm with him. Nearly all diesels
have a shut off solenoid on the injector pump. For it to start, it
must be pulled in by +12 volt. drop power and engine dies. When you
turn the key off on a diesel, that's all you're doing.

Karl, this is true for 4 cycle diesel engines and diesel engines that
HAVE injector Pumps. DD 53 and 71 Series diesels are 2 cycle and do NOT
have Injector Pumps, they have a common fuel Rail, and individual
Injectors, that are feed off the common fuel Rail at low pressure.
Also, it is not uncommon for a very OLD DD 53 or 71 that has a lot of
wear, to suck LubeOil up thru the Piston Rings, and run away. the only
way to shut them down in run away condition, is to shut off the Air
going into the blower, PERIOD. OR you can just let it go until it
EXPLODES, violently, with metal parts flying everywhere. Been there,
seen that....

For those who do not know, Bruce is the awesome moderator of SmokStak,
a great resource for diesel engine and generator owners.

The runaway is indeed a fearsome phenomenon, and that was why I asked
about air supply shutoff.
