Yank the valve covers and make sure the rack moves freely. It only takes one stuck injector to hold them all wide open. Common problem, especially after sitting for a long time

[@Luvs2Troll]

Yes!

[@ModelTTime]

Never start one that's been down for a long time without making sure all the injectors are free. They can really get your heart pumping! 😂

[@WieDrDerJonge]

I had the same with a 8V71 that sat for 10 years. The valve in the intake tube was stuck too but I pulled so hard that it came loose.

[@enginemaster01]

Unless you have a new style single screw rack

[@hobbyistliving]

a comon issue with detroits is when it sits for many years the fuel rail seizes up and when moving the trottle pedal it gets stuck wide open till you pull the valve cover off to free it up

[@grabasandwich]

From what I've read, they were designed to go to full fuel position when they're shut down, which is why they often stay stuck in full fuel the next time they're started years later.

[@jetstream454]

​@@grabasandwich That sounds right, given that a regular mechanical pump diesel defaults to full fuel when running below set speed (i.e. stopped)

[@ericgilhart5951]

I hate to see a Detroit get destroyed because people are to dumb to check the rack those engines are starting to be hard to find

[@J.R.in_WV]

They’re still out there, at least 20 series 71 and 92’s are listed for sale every week at Old Forge Power Products in Scranton PA and hundreds are listed elsewhere…..if you want to save them I’d suggest buying a few because when they don’t sell they go for scrap. The good news is even though they were pretty negligent in firing this one up it is likely still fine and a perfectly rebuildable core engine. As long as you don’t throw a rod or spin a bearing these can be rebuilt over and over again. In this case they did at least have it cranking long enough to build oil pressure before it ran off and it’s likely the bottom end survived since it was as still rolling over freely afterward.

[@RCRWJR]

[@Wasmachineman]

​@@RCRWJR Rack in this context is the rod that controls the injectors in the head itself. Watch KT3406E his videos about intentionally letting a 6-71 run away and you'll get what I mean.

[@joealbert7773]

Had an old mechanic tell me that after 30 years he never saw a diesel run away. He did see a lot of mechanics run away from one when it took off.

[@rad3766]

Pull the valve covers, put a pair of vise-grips on the rack so you have control of the rack while starting. A Detroit of this vintage will have the older style rack (2 screws), even one hung injector will hold all the others at full fuel. Ditch the ether. Prime the fuel system by filling it thru the top of the secodary fuel filter (gravity) pr by using a small pump.

[@john242ti]

Yup, the same thing that you see @BusGreaseMonkey do when he's working on a Detroit that hasn't run in a while.

[@zachzebra56]

When you go to start it after a while, take the valve covers off and make sure all 8 of the injectors racks move freely. These work just like the governor on the engine of a lawn mower. They are in full fuel when it's off and then move back to idle or full throttle when running. (Depending on the position of the throttle lever) The injectors can get stuck in full fuel. Leading to a runaway. Even if it's just one injector. If that engine ran like that for say about 5 minutes, it would seize up prematurely or worse, throw something out of the crankcase. So always make sure that the racks are free before starting if it's been sitting for a long time.

[@kolsen6330]

Ether has killed more engines than anything else. Watched a fool in Anchorage trying to start a frozen 8-53 mid winter. Used up 3 or 4 cans of ether. When he ran out, he got the cutting torch and blew pure oxygen into the air cleaner. The right cylinder head landed about 100 feet downrange.

[@Eric.schmidt]

Take that can away from her!!! Ya better check that rack. You answered you own problem with the accelerator being stuck

Awesome video. When I was working for a Equipment Co. back in the early 80’s. We got a IH cab over with a 8V92. One day the driver was bringing it in the yard and we was just thought he was showing off in reality it was running away. He had a hard time getting it out of gear with the sloppy linkage and thrust against the gears. We tried putting hard cardboard over the air intake, but there was to many leaks in the piping. Lol!! She finally stopped. We think she was running on the oil buildup in the air box. We tore her down only thing we found was she stretched her conecting rods. Put her back together and she ran good till we sold her!! Good luck with that one!! Thank you for sharing!!

You have to know what you are doing first grab the shit down lever make sure it’s free work the throttle make sure it’s free too make sure the emergency stop flap is there and operating as a lot say not a bad idea to pull the rocker covers and operate the rack tubes. The biggest thing fooling with these engines is to have a big CO2 fire extinguisher disconnect the air intake on the supercharger you can if you get a runaway stick that horn into that intake and discharge it till it dies ! The safest way to deal with one . I have ones from 2-53 all the way to 16-71s at my shop saving them for my older age .

[@Schlipperschlopper]

Never start an unknown old diesel without some CO2 gas fire extinguishers that you can empty in the intake!!! (No foam extinguishers and no powder extinguishers!)

[@JDZiemba1773]

When a Detroit runs away it's from a fuel leak on the top n the fuel drains into the crank case with the lube oil....when the level gets full to the bottom of the liner it pulls it up into the combustion chamber.....all the CO2 in the world not gonna do shit unless ALL the intake air is arrested.....🇺🇸

That was painful to watch. The most common cause of a runaway 2 stroke Detroit is a stuck injector, as many commenters have already said. But also a bad turbocharger with a leaky seal can cause an engine to runaway on crankcase oil leaking out of the turbo. On these Detroit engines a bad end seal in the blower rotors can also leak enough engine oil to cause a runaway, but that is very rare.
