My truck "ran away"!!!!!!!!

[hikethemtns]

Started my 03 the other morning and the engine "ran away",engine probably went to 10,000 rpm and i had diesel and oil running dripping out exhaust. Are my injectors sticking open??????? thanks jim

That is the likely answer or possible oil in the turbo.

But cold oil usually is hard to ignite.

How did you stop it?

 

[Vaughn MacKenzie]

Unless it's pretty cold weather there's probably sufficient heat from compression to burn oil in the cylinders and cause a runaway.



Injectors stuck open cause a knock. My guess is an injector leaked and flooded fuel into the oil, thinned it out, ruined the turbo bearing, which then leaked oil into the intake and caused the runaway.



Someone else had an '03 run away several months ago, buried the tach. Engine stopped when it dropped a valve or something, lotsa damage.

Your post is remarkably calm for having destroyed an engine!

Just a little food for thought, two days ago at my brothers work, a mechanic was out purging out a monster triple axle propane trailer, with a running truck nearby. Very soon the truck started to idle up and take off, as the mechanic jumped in it to shut it down the truck turned into a giant ball of fire. The guy is still in the hospital with some bad burns. Check out this news article and the picture.

OUTSTANDING READING. I was going from goosebumps to giggles reading that. Thanks.

A diesel runns away for one reason and that is , uncontrolled fuel delivery,

those reasons are, bad injectors, broken tip etc filling oil pan with fuel and the pistons dipping into the slop and there by running away,Also if you leave a diesel idle for a ton, of time I have seen Detroits idle for 2, or 3 days they will take off when you just touch the throttle, And last but not the least is a bad turbo seal . usually they will run whatever fuel source there is out and slowly die, not nesc blow up or lock . Good luck.

A fourth reason, and something that happens with some degree of regularity in the oil field, is ingestion of a flammable fuel source such as methane, butane, propane or other hydrocarbon gas into the intake. That's why diesels operating in the oil field will have air shutoff valves in the intake.

One of those shut-off valves would not be a bad thing to put on your truck. They are a little pricey though.

There's been some reading on air shutoffs in the competition forum lately. I guess they have to have them in pulling and racing rigs. Sounds like a good idea for day to day use. You could plumb it into your shorts. When the pressure in your shorts goes up to runaway engine, the air shuts off!
