Engine running away ??

[Adub90]

Someone told me that if you hold a cup of diesel in front of the intake or spray ether in your intake wile your truck is started that it will so called "run away" and reach rpms of 20,000 and throw a rod through the block. They said that it can even keep going if you turn the key on since it runs on compression ? Just wondering if any of this is true ?

I meant the key off pardon the mistakes

Well it can burn the ether but the cup of diesel part cant be true, diesel is just not volitile enough to make that much vapor

You would have to constantly spray ether in the intake. It would also come apart way before 20,000 rpm. But it would stay running with the key off or on as long as you were spraying it.

Why exactly would you want to do this? What is the point of this thread?

This can be useful for people who have been wrongfully denied warranty work lol

ive seen a few cats and one cummins "run-off" when i worked at a volvo semi dealer and trust me you dont want to be around when it lets loose

When the turbo seals go out the oil can go into the intake and cause a runaway also.

I'm a Diesel Generator mech, and I have also seen run-away diesels. Not a fun thing, when something that has no wheels, starts 'walking' almost 50 yards...inline John Deere 6.8ltr. Had to shove a fire extinguisher in the intake to make it stop. Stupid boot started and ran it with no governor on it, and the restraint cable missing. DUMB! Also just 2 weeks ago, I had an inline 4 (Ohnan same as Cummins just industrial side) go into overspeed and throw a piston head out the side of the block...that was an interesting night. Whenever we get home i'll post pictures of that, pretty cool, and sounded like the devil!

I have seen Detroit 92V diesels run away, I have seen the Cummins 250 inline six run away, and I have seen one GM 6.2L run away. It is not fun and not safe at all. I would highly recommend not doing this. It is very dangerous, because you don't know if your going to be able to shut the engine down. Also you do not know what will let loose if anything does. Or where the internal parts are going to come from or where they will go when flying out of the engine.
