I have been in workshops on a couple of occassions where this has happened, both times on Detroit 2 strokes. As the engine takes off to max rpm you may only have seconds to react or retreat! A CO2 fire extinguisher in the air intake will stop things pretty quick. NOT a drypowder or water based extinguisher !!. The cold shock may not be to good for it but neither is redlineing it.

as for all that dont believe you can damage a engine to over filling... I had my local dealer do the change on my 08 F250 Ford.... They didnt change to oil... they just added 15 quarts to what was there and immediately it started running rough... shaking really bad and no power at all... they told me it was low on fuel and to go get some.... if problem persist come back... So i drove it to the gas station, never made it... smoking like crazy, engine throttle stuck open to where i could hardly stop the truck, trani starts shifting all crazy to keep up with throttle.... long story short they are now replacing all exhaust... this system has a particulate filter... that alone cost $2110. Oil went in to the air filter all over any thing it could squeeze out of.... I get the truck back Friday... we will see what was done and will post the repair.

Way back when there was a particular brand, I forget which, of 2 stroke motorcycle that ran timing very close to TDC. They would occasionally, well fairly frequently, start running backwards. Being relatively high compression and difficult to start racing beasts and all. The drill was for the rider to ease the clutch the first time, to make sure it went that a way instead of this a way. Highly exciting, I talked to a guy that had one, says everyone forgets the advisde, till it happens to them..... Wee haw. |

A wood clipboard or a phone book put over the air intake will shut off the air supply to the runaway engine.
But you gotta be quick. http://www.youtube.com/watch?v=q4fxjKnuI4Y http://www.youtube.com/watch?v=WmkHTkmj2_U |

I agree there is risk of runaway on a modern diesel engine but before 2000 most vented crankcase blowby to the atmosphere by way of a blowby tube, not back to the intake.
As said near the top on an older engine a bit overfull isn't going to hurt as long as the crank doesn't whip it up. I have several diesel engines that call for amounts not in one gallon increments. They have been getting an extra quart for over a decade rather than having a quart left over in the jug. |

Ok Chris142, watching those were painful for an engine lover such as myself.

can anyone HELP?! I have a 2005 Ford Powerstroke 6.0l diesel that just had an entire upper engine rebuild and we dropped it off at the dealer for a FICM. Not only did they fail at the computer changeout, but for some crazy reason they overfilled my motor by 2.5 gallons of oil, started it, then it hydraulocked, then they forced it with a pry bar, then they re-started and it has loud knocking internal damage. Uhh...no kidding! Can anyone give me some info to help prove to the dealer that his people made a huge mistake, whether it's reading a simple dipstick or just plain stupidity. This is black and white, cut and dry, we know what they did because they told us. I just would like some info regarding what happens when you completely overfill a high compression diesel motor with oil, start it up then force it after it locks up. I would really appreciate some news. Thanks everyone!

Bent rods for sure,possible broken piston ring lands and rings,bent crank. They should be buying you a new short block. GET A LAWYER! With labor it sounds like the claim is to big for small claims court. TOTAL INCOMPETENCE to over fill and then start an engine. Genius has limitations. Stupidity is limitless. |

No question. A lawyer. Anecdotes are useful for stories and tall tales. To make decisions you need data. |

Overfilling old OM616 or 617 always results in loss of level, just keeping it near the full mark works well in those engines.
