A RUNAWAY IS WHEN A TURBO SEAL FAILS USUALLY TO THE IMPELLER SHAFT SHEARING IN HALF. THE ENGINE OIL IS RUNNING INTO THE INTAKE STREAM AND BECOMES FUEL. EVEN WITH THE KEY OFF THE ENGINE WILL RUN UNTIL IT IS OUT OF OIL. THE END RESULT IS SCRAP IRON AND A BIG REPAIR BILL.
"This engine was right on the edge of taking a shit." I've watched this video at least ten times just to hear that line... Love these videos! although I don't own a Powerstroke or even a diesel, i find this channel fascinating. Keep up the good work guys!
Hey this is beer calling I'm in the fridge nice and cold ....lol, great video
Sorry it is the Scottish blood. Some words just come out funny, especially when I'm jacked up on Red Bull doing a video.
powerstrokehelp thanks for your video i have a friend with a cummins isx and his turbos leaking i told him he needs to change it his reply was it cost 3000 so i wont replace it i told him it will mess up his engine eventually your video just proved i was right
I love red bull Bill. I know you own Spot the shop truck (7.3) and i know you had a 6.4 that poetically caught on fire, (im sorry man but you have to appreciate the irony,) but i haven't seen you own a 6.0 powerstroke. It seems like you mastered the 6 0 design flaws. Do you just prefer the 7.3? Id be interested if yoy did a video about why you do/don't own one
I really like your videos if i had the money id go to you and your team to make my 6.0 go another 200000 miles. Great content 12 yrs keep it goin
I love the saying "the engine nearly took a s**t" Describing the failure of an engine perfectly with all the oil coming out the bottom of it!
Look up "Scottish Elevator" in the you tube search bar. You'll get the point.
powerstrokehelp
I LOVE that skit.
Elevun... E Lev Un... lol
Thanks a million I am currently in C-school and they try to get this indepth with the subject material at hand but I think I will show the instructor this video. THANK YOU!
"This engine was right on the edge of taking a shit" hahaha. These videos are amazing!
I have 5 of them. the closest one was 400 yds round trip. By the time I got back the connecting rods would have been bouncing across the parking lot. Too many years and too many beers.
Had this happen today. After changing turbo left over oil fromold turbo caused it to run off the oil at roughly 5000 rpms. 20 seconds seemed like 5 minutes.
This engine was right on the edge of taking a shit (lol) it dident quite do it but.. lolol
+John Foster That line seriously cracked me up...something about the way he said it seemingly out of nowhere
Man thank you a billion times
for that video
it saved me an engime
Man, I had no idea that diesel motors could run away. You learn something new every day.
In all the year I have done this I have only seen it 4 times. But you will never forget the sound once you have seen it.
You are one of the best UA-cam presenters I've seen on engine mechanicals. I concur with some of your other viewers. You would make a great teacher on this subject. Most presenters on here can be pretty awkward to watch, so you should take advantage of your presentation abilities. Great work!
@1959Edsel It is my military background. I'm just a loud person.
Brilliant set of videos, you go into some real engineering detail, which for someone like me, is fantastic!. Keep up the good work.
Your FUBAR Series are my favorites of all the films you do Bill. You have fantastic expertise when working with Powerstroke Diesels.
Like Chaplain 161 had said, CO2 fire extinguisher shot straight into the intake will stop a runaway.
This was actually very informative for me, I'm a student in MMI in Orlando FL and am currently in my Diesel courses and you actually explained this to me better than my instructor did >.< haha. Thanks for the vids man, im gonna watch the rest of them
The way I look at it to run away is the purest form of full send
good video man, real easy to understand.
Man your videos are great. You remind me so much of my autoshop teachers very down to earth for sure and very honest. Thanks for the great videos Im studying to become a gasoline technician but it helps to know a little about diesel power so thanks again!
You could be an actor, very funny and entertaining. Love your videos, they never disappoint. I don't own or work on diesels but I am a self taught mechanic and student of science and engineering. It'd be really cool to work for you, maybe doing r&d to make a line of upgrade parts for trucks.
Nice video sir! I wish we had garages with people as good as you in the UK
You are the best. I am watching and my dad well stop and have to watch too. You just know exactly what your are talking about! Awesome ***** Stars
@shimrra Some oil coming out of the crank case vent is normal. you will always find some oil in the intercooler because of this. If you are consuming oil THEN you have a problem.
As always, great videos Bill!!! How I wish you lived closer to California! I know many people who could really use your help.
@killallianceftw When i was at AOCS back in the day. I was so loud the fire bell would be ringing in the hallway when I was at full military volume. Even the drill instructors were commenting on how loud I was. I am incapable of whispering, my voice just carries.
excelent explanation man... didn't know what a "diesel runaway" was!
im a chevy guy and i love the ford truck body style i use to look at these truck owners with envy ...been watching these videos about 2 weeks now i just feel sorry for these dudes
I love this guy's vids!
Keep up your Awesome informative videos!! I've learned so much from them. Thank you for makin' them!
@usmc289 some blowby oil is normal but if the truck starts to smoke excessively from the tailpipe then you have a problem.
I agree, the videos are fantastic
The automatic captions make this pretty funny.
Very informative and educational. Bravo sir!
Your vids are awesome! Trememdously help full!!!
Thank you!
Very informative. Looking forward to more vids.
Grew up in a Marine Corps family. Full military volume is how we communicate.
Fantastic video. Liking your style!
Sometimes the turbo oil return line gets all gummed up with shit. Next, you will be blowing seals...and the cascading consequences are note worthy
Just had my UK 2008 Ford Focus 1.6 TDCi do exactly this, however, no black smoke as such. I over took a slower car, got a small puff out the back, thought this might be the DPF clearing. Stopped at some lights, hello run away engine, massive cloud of white smoke. Its a shame I didn't know at the time how to stop it or what it even was!
@marek0086 The intense heat of the oil burning instead of diesel fuel made molecules of aluminum from the pistons float around in the combustion chamber and some of it ended up on the injector tip. NOT PRETTY
all diesels need to have a posi air shutoff, no exceptions
Keep up your Awesome informative videos!! I've learned so much from you.
put it this way coz he went with you he got a good engine and the job was done the right way the first time
Great insight on this issue friend!
Bill in seven years you havn't aged at all!
A CO2 fire extinguisher is the best way to stop a run-away diesel. No oxygen, no combustion. Or if you work on them for a living, keep a thick metal plate close by to cover the intake to choke off the air flow. Shop rags would be your 3rd choice. Good post. I like your videos.
we had a 6.0 run away in a e-350 van that had a turbo failure. it survived for a bit but ended up breaking a rod 3 months later.
@marek0086 Engine oil will burn in a diesel engine but only if the temps of the engine get high enough. In a runaway the coolant system cannot keep up with the heat generated in the engine. So as the engine oil is fed into the engine via damaged turbo seal, the speed of the engine pick up (sounds like a jet winding up for take off) and the engine gets hotter and hotter and will run until it runs itself out of engine oil. What is left after is all but scrap iron.
ROFLOL!!! The beer is calling. I never heard that one before.
You talk really loud.It wasnt until a user commented full military volume that I found it funny. Very good video and informative.thanks for sharing.
This is a really good video. You should honestly be a teacher if you're not already.
Hey I will show this to my brother. Quite intresting!
@kanewatman1 The best way if available is a CO2 fire extinguisher. Shoot it in the intake and it starves the engine of air and combustion is stopped. I had one where I actually took my shirt off and just stuffed it in the air box and that starved it for air. I literally gave the guy the shirt off my back, but it saved his engine. Brought me a big bottle of Crown Royal for that one.
When I was watching your vid would never think Ill find my PSA HDi having a runaway just 3 months after. Volume and amount of smoke is unimaginable. Luckily I was in front of the car and had a big cloth to shut the intake like you said before engine completely went wild in rpms. Can now say to all turbodiesel drivers, if your car changed its owner many times before - have condition of your turbo checked asap because ppl think it can be fixed with denial but it can't and WILL surely strike back
you're back!
keep up the work cool videos
Thats cool. In the old days when we would street race, we would put about a quart of Nitro methane in the oil before the grudge run. The Nitro would vaporize when we got hot halfway through the run and be sucked into the carburetor through the PCV valve and it was like Bo Jackson hit the back of the seat with a base ball bat. YEE HAA. Won some money doing that, but the other guy was too.
I keep a CO2 extinguisher in my truck to blast into the intake if I ever need too.
Nice video.
I watched a Duramax lose a turbo in this same scenario and go into a runaway. Very scary. Had this happened on the road, not sure how you could have stopped it without just grabbing neutral and letting it blow. Engine was stopped in the shop by shoving a 2x6 over the intake duct from the air filter, but only after a HUGE amount of valvetrain damage was sustained. Engine was replaced.
@jaded16340 There will always be some oil in the CAC from blowby at the driver's valve cover. If your truck is consuming oil then you have a problem.
We tried from the exhaust end but it pushes out so hard it doesn't work. It is best to work from the turbo end.
An air shutoff valve is a very worthwhile investment, for example a Chalwyn.
I agree but it was a good 200yds to the shop. I dont run that fast any more.
Great explanation of when a "blown" turbo may cause a runaway diesel engine.
Which is a terrible situation (BDDT but saved the engine). :)
Your Videos are great!!!!!
Another good vid.
Good video, very informative, keep up the good work. Cheers
I saw a Leyland Beaver go wild in about 1960.When the operator went to shut it down, he released the stop cable too soon. The motor stopped, kicked back and fired up , in reverse. The mechanical governor went wide open and pulling into top gear and using every bit of brake available, it was subdued. Cab full of smoke; draws full of something else!!
In the old 12 valves it was the govenor arm getting stuck under the fuel plate....can be a number of things i guess
@powerstrokehelp Thank you very much i appreciate the reply i know you guys are real busy.
Great video! I've enoyed it very much.
this guy needs his own tv show that was some funny shit
good vid. i find ppl just dont know how quick a engine can get fryed.
The motor is broken in well and you have the correct tune for your application, then fuel economy can be over 20.
Yes with a stick shift you can stall the engine, but automatics cant be stalled. CO2 fire extinguisher is the best solution.
board or phone book over the intake of the turbo works best for shutting stuff down. Rag can pull your hand in...
keep making videos there very helpful
This is why marine diesels have an air block in case of a runaway. Usually its your only hope to save it.
@powerstrokehelp - Not "only if the temp gets hot enough"...the compression ignition idea itself creates the heat needed to combust the oil. How do I know? We had an ISX runaway from a crack in the cylinder head at the top of the intake port...once turbo piping was removed and we started it, it lost positive manifold pressure allowing oil to go into intake and let the engine start to runaway. Was stopped with a book over the intake elbow...and that engine was shop temp, about 68 degrees...
your the only guy i could find explaining a runaway thank you great video hope it never happens to me. were you able to re use the block of this motor?
Good to know, thank you very much :). What can make a big difference I think is that you are on 6L quite big engines when I think about European engines as mine. I have 1.7L turbo diesel engine right now which is most common in such of cars here. I think there is no as much pressure on the exhaust in that engines and at the same time getting close to the turbo is almost imposible where there is no much room around the engine and it's located behind it.
fire extinguisher is the best!
The oil is burnt until it is used up and the engine siezes or blows a rod out the side.
I suppose so. I have only seen the PowerStroke version of runaway.
It will knock holes in the pistons also.
I'm sure if the engine gets hot enough it can, but gas engines dont have as much compression as a diesel. So it will probably just start smoking and foul the plugs and not restart.
Very cool video, that thing got f'ed right up
real interesting, i had no idea what a "runaway diesel" meant to begin with...
When I was doing wireline work we had an H2S gas leak on location. We had no time to shut down when the alarm went off. We mustered up and our wireline truck (Kenny T440) was still running. It was close enough to the location of the leak that it had a run away start. The leak was shut after a few min and the engine idled back down. But it was trashed. It ran, but was in very bad shape. We kept it alive long enough to rig down, then shut it down. A new truck was sent out and that one went back on a wrecker. That truck was gone for a month to get a new engine.
+Chad Bremer in hind sight, we are lucky the H2S gas did not ignite and burn the location down. It has a pretty low LEL. Just never made it high enough in the open to go boom I guess.
So H2S gas caused the runaway instead of oil? You are lucky!
i had the same problem with my car 2 years back.. its a 1.4L diesel
engine started revving crazy even with the key in my hand! it ran at the redline for about 5 minutes before it died out.
the car cranked right up after that.. drove it a couple miles to the dealership and then another 20 miles the next day as the idiots there couldn't figure out what happend.. they thought i'd run it without oil. anyway. got the turbo replaced.. and the car is working perfectly fine now! :)
no rebuilds, nothing!
Did this to an International 9670 with a 350 cummins diesel. Epic destruction!
@powerstrokehelp It's not the different fuel so much as the the copious quantities of engine oil being ingested (much more than the injectors would ever normally feed the engine) and the fact there's absolutely no timing what so ever to the start of ignition.
The oil is already present in the cylinder before the intake valves close and fully free to ignite whenever it pleases on the compression up stroke.
The result, preignition, is what melts the pistons and injectors. Or clogs the latter.
You only talked about 1 cause of runaways. Fuel rail failures, fuel leaks, overfilling oil, others. You can tell the difference by the smoke. Gray-blue thick/dense smoke is an oiling run and usually(not always) lower RPM. Black(er) smoke and super high RPM is most often fuel rail or other fuel issue. Sometimes the damage (like the sheared turbo shaft) is secondary to the main failure cause. Detroit, Rolls, and many others have air shut-off flaps to prevent this. Most industrial applications require this. Even non-turbos can runaway.
Hes right.. my 6.4 had a fuel leak and oil level was so high the turbo sucked it up and it was crazy high RPMs. It lasted about 45 seconds and its sitting at the shop now to see if any damage was done
Brother Im not getting that close. I dont want to pick shrapnel out of my lower leg when one of the connecting rods comes flying out of there.
Id like to see a picture of that.
That would work if you had one in your truck but not many people do. I've always said about a safety switch that would close a butterfly valve in the intake.
Hey I like your synopsis on the Ford 6.0 situation. Great video but comments are restricted.
Have you witnessed any runaway of a NON-turbo diesel engine?
P.S. Thanks for very informative video, I've enjoyed it and that was a lot useful information for me.
Happens to the supercharged Detroits a lot.
