Thinking that engine pushed a bus for a couple of millions of mile and didn’t complain is sad . They were masterpieces of their time and much respect !
The 6-71 was first built in 1938 and used in war production, the Gray Marine 6-71's were used in almost all the landing craft all over the world, Detroit Diesel stopped making the 2 stroke 71,53 and 92 series in 1995. I operated and worked on hundreds of them in my 26 years in the military, they were good reliable engines that you never had to worry about anything in a 5 foot radius of rusting because it was always covered in oil!
They were only removed from production in 1995.... for "public consumption". The US Gov't still maintains their use for US and allied military vehicle contracts, with "on demand" contract orders. The 6-53T&TA as well as the 8-92TA is still "on the books"... albeit, out of public view. The 8-71TA was also carried until 2015.
@@Busdude97.... Not since WW2... we had several different tanks & tank destroyers (M10) with them, as well as APC's, Navy "Brown water" fast gun boats on the Mekong River and elsewhere, during the VN era, and later. Just about every boat from Navy launches, to landing barges and everything in between were generally 6-71 DD powered. They probably would have been 6-110 powered, if they had, had the engine ready during WW2... instead of right at the end of it, in 1945.
The Light Armored vehicle (LAV) the marine corps uses was 6v53T powered well into 2018 when I got out. Also the M113 the army uses had them, though I want to say they'res wasn't turbocharged and also didn't have Jacobs brakes as they were in a tracked vehicle, vs the LAV being wheeled. Very neat engines to have much education or experience on when you're less than 40 years old
Sad to see a great old engine like that being destroyed. I operated heavy equipment with those engines in them. lots of noise but would run three shifts every day no problems.
I was really impressed how that old Detroit 6-71 suffered that punishment! Unbelievable! I was holding my breath and thinking any time now for it to blow up or for that matter to lock up! Tough, Tough old motor for sure!
That 2 stroke sounded in good shape when it first fired up.....can’t believe it stood the test at full throttle for so long without any coolant. What an awesome engine. It’s a tribute to GM I drove one for years. Used a gallon of oil every 500 gallons of diesel and started even at 30 below. Hit the starter and turn it over several times. Stop. Wait a few seconds to allow the heat to transfer a bit in the cylinders. Fire it again and she’ll start every time.
It’s sad how people don’t know these were some of the best engines ever made, and they’re getting pretty rare especially when people make them blow up on purpose which I’ve seen done many times
Yep. its a Fucking TRAVESTY!! One day if the world does finally go to shit those old detroits will be worth a fortune because they can STILL run..The modern shit wont last.
Back in the early 90s when I was a diesel apprentice tech, all we did for months was tear apart these engines for cores. An old man who is long dead now used to bring them on pallets by the dozen. Whenever there was down time from slow work, we went out and filled a whole bay with these things and tear em down. Brings back memories.
Thanks for sharing this video friend. All of these years operating equipment and driving trucks I have never seen one of these engines lock-up. They are definitely a mighty tough engine and I have gained a whole new trust for the 671 Detroit diesel. Thanks for your time friend.
Those old Detroit’s were amazing engines in their day...and “their day” lasted for about 60 years so Detroit did something right...aside from their noise, their biggest down fall was their fuel consumption...I worked at a construction company that had a mobile crusher and we brought it to a big rock job we were doing...the crusher was run by a generator that had a rather large Detroit in it..V16 if I recall... when they fired it up it ran like a champ but loved it’s fuel...so much so that the superintendent rented a brand new Cat generator to take its place...after about a week of running the Cat he figured the cost of the fuel saved paid for the rental of the Cat generator...I believe they scrapped the Detroit generator after that job...it was a shame really cuz there wasn’t a thing wrong with it but it was made back in the day when diesel was 10 cents a gallon...if you had endless amounts of fuel to run through it then it likely would have kept running for decades!!..the 671 was one of the best all around engines they ever made...this abusive run is a testimonial to how tough they were!!.. good video!!
Not just thirsty, but noisy, dirty, leaky. I dislike them in boats, they belong in a logging truck screaming its guts out. When they try and use them in displacement hulls they are thirsty, dirty, noisy, leaky. I know they have lots of admirers, but Im not one of them.
There still decent engines people would rather have run cats or Cummins engines but imo there not as cool or fun engines I run a grain truck and we got a few pieces of equipment where I work with these engines in them.
Can’t remember...over 25 years ago...but they ran it hard so I would say it was pushing 2100rpm...if I remember correctly it was burning about 150g/hr...the tank on the generator was about a 1000g and then they had secondary tanks set up with it and it would suck them all dry in short order...it wasn’t a small crusher by any means...it was drawing a great deal of power!!..when the cone was crushing to 3/4 it was pulling well over 300amps...
I cannot believe how tough those things are. It ran all that time wide open with no coolant and didn't lock up. I wish u took it apart I bet some exhaust valves burned off and compressions to load to fire even with ether. Very impressive.
Whatever people might say negative about a 2-Stoke Detroit Diesel especially the 71 Series no one cannot deny the fact they are tougher than woodpecker lips. It absolutely amazes me that the 6-71 was made basically unchanged for 75 years and the only reason those oil drooling annoyingly loud pigs that turn diesel fuel into noise and smoke without making horsepower is the government basically outlawed them because it sure and hell wasn’t because Detroit Diesel wanted to quit making them. Personally I have a soft spot in my heart for the green leakers’ mostly because the first truck I drove for a paycheck had a Buzz’en Dozen in it.
gullreefclub..... Where or What, gives you the idea that "without making horsepower" was a characteristic of them? You, like most out there... are completely devoid of how they actually function, and if you did know and understand... your jaw would "drop" in amazement. By the way, the 6-71 was in production for 57 yrs, 7 months (Jan.1938 - Aug.24th, 1995)... Not, "75 years" (2013).... but still, literally and Officially holds the World Title for being the Longest Production run of ANY reciprocating engine in history, as well as being the most Reliable. The 110 was also, every bit as reliable along with power potential and capability Far beyond what it was producing during that era, and was massively "over-built" for that purpose, however.. division "heads" wrongly decided to drop it from the line-up in 1965. It was truly "an engine ahead of its time" in terms of power capabilities... such a shame that the metallurgy of the era in transmissions and drive-lines for HD On-Hwy trucks had Not yet caught up to it.
Your comments are of a fool. Back in the day, when a 230 horse engine was all anyone made, the 238 was king, leader of the pack. My dad had a 61 Mack with the 230 turbo charged Mack engine, and his brother had a 238 in his truck. The 238 walked away from the Mack in every situation, getting better milage than anything on the road, cause it burnt 98% of its fuel, instead of blowing it out the exhaust. You are comparing a 75 year old engine to modern technology and making fun of it. The 2 cycle Detroit built modern America. Give it its dues. By the way Mr know it all, Cummins is building that engine again, to go in semi trucks in 2025....
😂 Well, that was fun! I’m retired now but for most of my working life I ran large stationary diesel generator sets (Air Force & public utilities). It’s been so long, I don’t remember model, displacement, etc. but we had these two Nordberg 1000 kW units that were 7 cyl in-line 4-strokes. I think the cylinders were 18” diameter with a 32” stroke. Roughly 13’ from the bottom of the oil pan to the top of the rocker covers. Nominal speed was 327 rpm. They were a ball to operate. The cast iron pistons were prone to breaking around the ring grooves. It happened to me one time. What a racket! Two crankcase explosions in rapid succession filled the plant with thick black smoke. They had spring loaded crankcase pressure relief valves or it would have detonated. I ran out the side of the building and had to re-enter to shut it down at the front of the engine. The mechanics said the CC explosions were very minor. What a rush! The serial numbers were 3 and 187. The first two built were sent to a Texas oil field where one of them exploded and killed every man on the crew. After that they installed the CC pressure relief valves. That was in 1948. I worked there from 1983 to 2000. After I left, they closed the plant. It’s too bad. Should have made a museum out of the place. Oh well.
Man, when they run away get away!! I tried to stop an 8v71 with a clipboard over the open blower. It didn't work. Engine sucked in like a log chipper. Then we ran away. Boom n bang.
i felt sad to see this engine being destroyed . i like your videos i will stick to watching your engine rebuilds no more runaways for me . cheers . yes i am an old timer
Yeah, kind of sad to see something get tortured to death. I guess it was destined for the scrap yard anyway, but still, would have been cool to seen it in an old vintage boat or running an off grid generator.
I have a 1954 Greyhound coach, with the 6 cylinder. I am extremely impressed with the power of that engine !!! I had no idea !!! Way to go DETROIT DIESEL !!!
Those things moved so much air that they could self cool the liners while revving to the stratosphere. As mentioned before, the rev limit when full-rack is usually valve float. Would be cool to hear one with a Jake rev and throw the jake:)
Aww hell yeah man I love the sound of those! Just pure 'Murica right there... oooh i can almost smell it, too... awesome. Just.... fkng awesome I think. Almost comforting in a way as well lol thanks!
My last boat had twin 6-71 turbos, they ran beautifully. After 700 hours of use, I never had a single issue. When I sold the boat, they had 1,900 hours and would barely blow a puff of smoke upon start-up (normal) and ran clean. I used Lucan during oil changes and it stopped the oil burn. They are EXCELLENT engines. Change the oil and fuel filters and they will run for ever.
Greatest diesels if all time! Got a cult following for its simplicity, ruggedness, amazing sound, war heritage and smoothness. Detroits are timeless classics. They deserve a full restoration in a truck or mounted in a man cave an run with the boys over a beer!
I am a retired diesel tech of 40 years. That inline 6 71 could have been sitting for over a year. I worked for a company that was shut down for 14 months. Had to get several trucks started. Installed some batteries in a truck with a 6v 71. It started with only 1 revolution. Now of course, if it had been cold out that would not have happened. Now the older 6 71 ,if it had an injector stuck in full fuel,it would keep the other 5 in that position and run away. The newer ones had what was called a broken backrack. That would allow the other 5 injectors to return to the no fuel position.
I am a Detroit fan, it was an 8V92TA that got me into loving the strokers. I know people are upset that this engine was tortured and killed, but there are literally millions still around that are in service or rebuildable.
The deepest evilness lying deep inside human's heart... To destroy and to torture for no reason but the most demonic type of psychological fulfillment - bloodthirst and sadism. Overclocking and destroying a machine for fun is generally not against the law. However the purpose of doing it and the gain from doing it is nothing different from torturing animals or even human.
Well…that engine spent the whole of it’s working life…giving the environmentalist a two fingered salute….in its final run…a Smokey outdoor …single finger one ! Great videos thanks
your delivery of commentary is every bit as good as anything you actually put on video-and i love all your videos. good to see ya man and look forward to the next one
I worked on the Detroit Diesel 53,71 and 92 series assembly line from 76'-83' performing different jobs,pushing pistons,dropping cranks in,pushing cams,setting timing etc. There were a couple times that some of us were taken back to the engine test area and were shown what happens when somebody didn't torque the piston rod caps properly. It's not pretty when ya see a rod poking through the side of a block.
In the 1970's I drove an old 1951 GM 4103 coach with a 6-71 and a 4 speed tranny. I come into work one night and the boss/owner takes me aside and says he's putting me into a coach that night that was just rebuilt. He said take it easy on her, the dashboard oil pressure gauge registered zero but the engine compartment gauge showed 8 psi. I make it the 67 miles out to the turnaround point, but coming back home about 20 miles into the run while pulling a fairly decent hill the engine developed a dead miss. Had to downshift to third to keep going as no room to pull over anywhere. Engine starts missing on a second cylinder, and loosing speed fast. I downshift second gear trying to make it to a wide area just up ahead when heard a loud bang and she went dead. Kicked in the clutch and tried to roll to the side as much as I could. Got out and walked to the back ending there was a river of oil flowing down the road. There was a huge hole in the lower side of the block where #4 cylinder was, and it tore the oilpan half off. Stuck there for the rest of the night until the boss arranged to have a hook come out. I guess even these "indestructable" 2 strokes won't run without oil pressure!
Yet my friends can’t understand my interest in Detroit engines. They were built to last, I’m sure with a little bit of brain power we can figure out a way to make it have more power than a Cummins.
I built many detroit engines ......why do you want to blow the old up .......kinda sad to me annnnnnnnnd pointless what a waste and shame buts thats just me ......
Good ol screaming Jimmy's. Love to see the content. Thanks for the piston/connecting rod from the giant CAT engine, hangs in my garage. Great content, keep up the good work.
👀would have loved to see engine temps with an IR thermometer: block heads,manifold, etc.... still impressive as hell. Nice job. Always a pleasure. Thanks.......
yea, he did a teardown and it ran so hot the the manifold did crack and some other damages, but other than that it did turn over and held together at the end of this video
*They used to put these old 6-71 and 8-71 engines in many trucks, buses, and boats back in the 80s and early 90s. You can't miss the sound of one of these engines hammering down the road, like music to my ears.*
Just OUTSTANDING!!!! I mean can we appreciate what this Detroit just did?! It served a long long life and then gave us a spectacular ending that no new shit could come close to……. WOW WOW WOW 🎉🎉🎉🎉
I worked on the 671 back in the late 70's to early 80's in the Navy. Love that engine and it's sound. Operated "pusher boats " in Subic Bay boat pool. Had two 671 Detroits and even an LCU from WWII with 3 of them for propulsion and 2 471's from generations. Lots of FUN. It was interesting to see you run that one so long and not see it fly apart! Very COOL. thanks for the video. Brought back a bunch of Good memories. 🇺🇲👍
@@bikeman5 Yes I've had to go through the gate and across the bridge over "shit river" too. Don't remember the name san marcelino right now. Was that just north of Olongapo? Some friends and I rode our bikes down to Angeles close to Clark Air base because there was no curfew there. Partly ALL night there! LOL
@@bikeman5 No, actually I was stationed in Subic Bay. It was a small town back in the late 70's. We rode the bikes to Angeles from there to party. I'd ride in to SM as you put it from Subic where I rented a house on the beach where a retired Marine owned a bar and rentals. Very Cool place. It's been a few years so I think that's the place anyway.
I did this in Iraq to 2 hmmwvs with the old 6.2 in em back when our government didn’t leave good equipment for the enemy to use. No oil, no coolant. They ran for over 45 minutes until they slowly died. We were able to start them back up after they cooled down but not for long
@@ChicanoOne760 Hey man I was just taking a shot at my old boss while reminiscing on an old story. I never mentioned any sides or why I think one is better than the other.
You literally had to turn the oil into steam with the patience of a Monk to make that thing "seize"...my Lord what and incredible piece of engineering!
I need an 8 v71 and a 12 v71 to through outside and run . Reminds me of my dad's trucks he had back in the day. Don't worry the neighbors will love the music . They don't have a choice
Just like Deboss....the old Detroit Diesel guy said he'd never seen one that wouldn't start that didn't have something sticking out of the block...amazing they don't seize! Theirs was a 16V though.
For all those too challenged to educate themselves on the ordeal with doing a runaway on a sack of shit that burns oil left and right with so many hundreds of thousands of miles of wear within(the kind that would cost a hell of a lot more to even attempt fixing compared to buying a new one), there are three things you can do with it. Melt it down for the metal at the scrapper's shop, make it runaway then use it for an ugly yard ornament or melt it down, or just leave it to rot. What I'm trying to say here is that this is the funnest way to handle nearly every engine on it's last leg. If anything, I see this as more of a glorious send off to celebrate the amount of Wonderful things the motor did in it's life. Better said as going out with a bang.
That was amazing I didn't know the 6-71 could sound that good past governor, especially with the fire coming out of the exhaust, I have to say past governed full throttle, this has to be on of the most amazing sounding diesel engines ever. Now that 8v71 I liked how the blower sounded like a 4 stroke with the fan on , but that 6-71 takes all the gold in my opinion.
If u love this sound u should hear a gm emd locomotive at full throttle with a 645 v16 2stroke basically the same motor but alot bigger they have a heavenly sound they come both turbo charged and non turbo charged best sound in the world
Drove a 6-71 that the company mechanic turned up the governor to 2600 rpm. He was a Mack mechanic and hated Detroits and wanted me to blow it up, but it lasted the 3 years I was in it, and it ran strong! Would out pull a Cummins 290 in the fleet, and ran circles around the many 237 Maxidynes we had. It had a weed burner horizontal exhaust that would throw an 18 inch long flame at high rpms, lit up the bottom of the trailer, so the boys gave me the CB handle Wildfire. The good old days...
Thanks for the time you put in to let folks like me learn about how diesels work- and come apart. You are a good, clear explainer for the new and ignorant.
Just to see not to fix after the fact!! How bad each 1 was like real world will help to save people's lives when they depend on equipment to not cost so much to fix at the end of the day !! Well that's why I would like to see and know !!
@ Frank Kreyssig Nah he is scared that the Cat engine gives up earlier than the GM. Now THAT would make this Cat hugger look dumb. It's almost like this guy has a share in the Caterpillar company. The only good engine in his word is a Cat but i guess Cat cares Just as much about him than cr*p under their shue's
Those were the good old days over the road rigs working trucks coming into the shop for service tune up or engine over haul miss those days and working on all Detroit's and other diesel engines😍💯🙏😎💪 got to give it throttle
Dude! The environment! Bwah ha ha! Thanks for the entertaining video. I can only imagine that if you'd hooked up a cooling system to that thing and a bigger fuel supply, it could have run for days. Incredible.
I know you have plenty of these old Detroit’s to destroy it’s great to whatch I use to run these same engines in the trucks I drove and had to fix back in the early 80 and late 70 on the road and the farm always loved these screaming demons keep em coming thanks agin for sharing
Always makes me a little sad to see an old detroit die in your videos but still very interesting and impressive, and I usually learn something. Shame I can't get one here in the UK id love a 2 stroke detroit v8 to rebuild and use
Yup and this guy is blowing them up and dumping them. Theres millions of them that were made, but they dont make them anymore and never will again. So fuckin sick of the newest generation of gearheads, too many have no creativity and blow shit up for no good reason.
I'll just use that method of removal, on that air intake. that's what I like about KT3406E. he tells it the way it is. I was an OTR truck driver and I was taught to never lug a Detroit. always keep them wound right up against the governor. but this is a demonstration of what happens. when you take them into the danger zone.
Dang old Detroit tough as hell and that's why I like them, overrevved ran low on oil, overheated and gets crap fuel mileage but damn if they won't always crank up and run and do the work you need them to do.
The 92 series was a an improvement over the 71 series engines. but now they are all outdated. but back in the day they did the job. they left my ears ringing more than a few times.
Welcome back man! As always, it’s phenomenal to see your content even though it’s so long in between. But we get it. You’re a busy, hardworking young man. Just grabbed a tumbler of Kentucky’s finest on ice and am gonna settle in and enjoy this ride!
F it, Putting one with a turbo into a custom build prototype racecar and see how well it would compete against modern gas powered race engines would suit my style(massive torque=haha car go speed,who cares about weight anyways)
Early 80's ,I ran Captain on 110' offshore crewboats in South Louisiana. With a fleet of over 40 vessels, (all aluminum hulls ,which were like carbon fiber today.,,,I choose the older crewboats,(the owners collection,lol.)( built like a Cadillac,,,but sound like the engine room was going to explode any minute running 4, 6-71 in a aluminum hull,(i ran mostly only 2 engines,,, wide open 5+ hours at a time.Very dependable engines,,,,just add oil and go fast. thanks for the FLASHBACKS!!☆☆
Got me into runaway diesels Thank you my man I work on a golf course and have some engine repair experience My course has a mechanic and he is certified in diesels So we have an old Jacobsen 5111 We had the authorities come and ask us to clean up our old units So I asked my boss if we could induce a runaway or overspeed He said sure So this Friday I'm going to try to get her to runaway or blown up I'll post video
Don't blow up a perfectly good diesel just for the "lulz". Those Kubota 4cyl diesels run forever and there are plenty of people who would pay good money for it.
@@johnfox3845 it's shot We had it on turf net for a year no one wants to buy it So before we take it to the scrap yard let's have some fun I can't do anything until after October 16th I have total permission to have some fun with this engine
@@inrainbows1829 If the engine still runs, there are numerous people who would buy it, regardless of how worn out the rest of the machine is. If you listed it on Craigslist or Facebook Marketplace at a reasonable asking price, someone would certainly pick it up. While the market for a worn out Jacobsen 5111 is likely to be quite small, the same cannot be said about a running Kubota 2.2l 4 cylinder diesel. There are always people looking for diesels of that size for many different applications. Hell, there's even a market for the engine in non-running condition, as long as it is rebuildable. Deliberately destroying an engine that is in demand makes little sense. For the sake of curiosity, in which state do you reside and what is the asking price?
Perhaps next time you could give it coolant, and connect the crank case breather to the intake, and also advance the camshaft 1 tooth. Setup a remote controlled oil pressure reduction device in case nothing happens
Thanks for the videos that you make. They are very interesting and informative. Back in my days on the family farm, we had several Cat tractors. A D4, D6, D8 and the big guy, a D9. I always enjoyed driving them, at least for the first hour or so !! 😝😝
On our family farm in Washington state we had two D5 Special Application tractors and two D6 Series C tractors. I would spend 10 hours a day in them, seeding wheat, plowing, rod weeding, fertilizing, spraying 2,4-D.. You definitely needed ear plugs. The 6s were pretty powerful, but the 5s were almost as powerful and got the job done.
It’s damn hard to kick the rods out of a 6-71 because the rods are extremely beefy and the crank and rod bearing surfaces so big. Now the V series Detroit’s especially the 92 series they’re a different story
If he wood have put on a radiator and had coolant in the motor, I don't think he cood have blown the thing up. It probably shut down due to heat melting things.
Wish you would fly apart something that was actually clapped out Worn out 6.9 or that 8v71 That 6-71 seemed like it was a good engine considering no smoke and started easy
Exactly. Perfectly running old engines always end up in the hands of some dirtbag that wants to ruin it rather than fix the little shit wrong with it and sell it to someone that will put it to good use. Why do you think classic muscle cars are so hard to find. Too many assholes ruined good ones.
I drove a 3 car hauler (used to be a 4 car but they removed the number 1 spot head rack) it has a 2850 rpm turned up all mechanical and she just fuckin eats and goes. Thing can pull down a house and go over 100 like it was nothing.
I'm always a little sad to see an old Detroit 71 series go out. Good video though brother! If you have any spare parts like supercharger, injectors or anything else I'd love to see about buying them from you I've got an old Euclid 72-20 loader with a 3-71 in it.
When your doing something like trying to start a engine after it almost locked up use a combination of WD-40 and starter fluid to get it turning fast enough to start again because the reason it didn't start is it wasn't turning over fast enough

Whats fkd up is they dnt make them that tough anymore. Look that she wants to still go
Trying to kill that old Detroit was about as difficult as keeping new shit running 🤔
That old Yamaha has already run longer that most all of this new shit!
Amen to that 👍
Which is why he shouldn't be doing it.
If it's going to the scrap yard what's the difference?
It's a free country for now and his private property, he can do whatever he wants with it.
They were phenomenal engines for their time,no other inline six in the world could run that long under wide open fuel and no coolant.
Valve float saved it from scattering parts maybe.
They were originally designed to run for 10 minutes with no coolant in Higgins craft landing boats so they could keep the hydraulics running
Yeah, it only stopped because it obviously heat- seized. If that had coolant it would have been fine.
You can even see it backfiring too
Absolutely amazing this thing powered our boys to victory on D-DAY!!
Those old 2 strokers were screamers. Had a lot of fun with them back in the good old days. We will never see engines like those ever again.
This is what was in a lot of our fire trucks 🚒
The v8 is the same as an M578 recovery vehicle
False stop spreading lies that you have been told by the tv and hype for non functional electric vehicles. 😊 Have a nice day.

Could put then in a old engine museum.

I was really impressed how that old Detroit 6-71 suffered that punishment! Unbelievable! I was holding my breath and thinking any time now for it to blow up or for that matter to lock up! Tough, Tough old motor for sure!
That 2 stroke sounded in good shape when it first fired up.....can’t believe it stood the test at full throttle for so long without any coolant.
What an awesome engine. It’s a tribute to GM
I drove one for years. Used a gallon of oil every 500 gallons of diesel and started even at 30 below. Hit the starter and turn it over several times. Stop. Wait a few seconds to allow the heat to transfer a bit in the cylinders. Fire it again and she’ll start every time.
Feel angry when people destroy things like that.
@@arthurheckendorf3324 well keep staying angry thing is they made alot of these like this didn't put a dent into any number of em.
Who ever you are, I love this story it comes from a real driver.
Hello we heard you have oil is that correct?
Can't help thinking someday we might wish we still had these engines around.
There are plenty of Detroits around. This didn't even put a dent in the number
My fleet of buses run 6V92 / Series 50. Solid engines.
@@Mr.Badger69 how many bone head are destroying them "cuz its fun"?
What about re-manufactured Detroit engine from any good reman company? Not talking about refurbished engine.
@@Mr.Badger69 where can i find one cheap? i would just like to have one
It’s sad how people don’t know these were some of the best engines ever made, and they’re getting pretty rare especially when people make them blow up on purpose which I’ve seen done many times
Yep. its a Fucking TRAVESTY!! One day if the world does finally go to shit those old detroits will be worth a fortune because they can STILL run..The modern shit wont last.
They are NOT rare. Millions upon millions were made and they're still everywhere
Rusty angine go brrrrr
Maybe you need to start a engine rescue business
I have 2 12V71TIs on my boat. They run like champs!
Back in the early 90s when I was a diesel apprentice tech, all we did for months was tear apart these engines for cores. An old man who is long dead now used to bring them on pallets by the dozen. Whenever there was down time from slow work, we went out and filled a whole bay with these things and tear em down. Brings back memories.
I hate to see them go, but love to watch them leave RIP 71 series!
Thanks for sharing this video friend. All of these years operating equipment and driving trucks I have never seen one of these engines lock-up. They are definitely a mighty tough engine and I have gained a whole new trust for the 671 Detroit diesel. Thanks for your time friend.
You cant kill a detroit. Even after running wide open it still wants to start and run. Amazing piece of equipment and history as well.
That thing does not want to start and run. A pint of ether and the thing didn't even cough.
Piston rings might be shot
Those old Detroit’s were amazing engines in their day...and “their day” lasted for about 60 years so Detroit did something right...aside from their noise, their biggest down fall was their fuel consumption...I worked at a construction company that had a mobile crusher and we brought it to a big rock job we were doing...the crusher was run by a generator that had a rather large Detroit in it..V16 if I recall... when they fired it up it ran like a champ but loved it’s fuel...so much so that the superintendent rented a brand new Cat generator to take its place...after about a week of running the Cat he figured the cost of the fuel saved paid for the rental of the Cat generator...I believe they scrapped the Detroit generator after that job...it was a shame really cuz there wasn’t a thing wrong with it but it was made back in the day when diesel was 10 cents a gallon...if you had endless amounts of fuel to run through it then it likely would have kept running for decades!!..the 671 was one of the best all around engines they ever made...this abusive run is a testimonial to how tough they were!!.. good video!!
Not just thirsty, but noisy, dirty, leaky. I dislike them in boats, they belong in a logging truck screaming its guts out. When they try and use them in displacement hulls they are thirsty, dirty, noisy, leaky. I know they have lots of admirers, but Im not one of them.
And they leaked oil like an old Harley
There still decent engines people would rather have run cats or Cummins engines but imo there not as cool or fun engines I run a grain truck and we got a few pieces of equipment where I work with these engines in them.
How high was it revving?
Can’t remember...over 25 years ago...but they ran it hard so I would say it was pushing 2100rpm...if I remember correctly it was burning about 150g/hr...the tank on the generator was about a 1000g and then they had secondary tanks set up with it and it would suck them all dry in short order...it wasn’t a small crusher by any means...it was drawing a great deal of power!!..when the cone was crushing to 3/4 it was pulling well over 300amps...
I cannot believe how tough those things are. It ran all that time wide open with no coolant and didn't lock up. I wish u took it apart I bet some exhaust valves burned off and compressions to load to fire even with ether. Very impressive.
Whatever people might say negative about a 2-Stoke Detroit Diesel especially the 71 Series no one cannot deny the fact they are tougher than woodpecker lips. It absolutely amazes me that the 6-71 was made basically unchanged for 75 years and the only reason those oil drooling annoyingly loud pigs that turn diesel fuel into noise and smoke without making horsepower is the government basically outlawed them because it sure and hell wasn’t because Detroit Diesel wanted to quit making them. Personally I have a soft spot in my heart for the green leakers’ mostly because the first truck I drove for a paycheck had a Buzz’en Dozen in it.
92 series were absolutely awesome too.
gullreefclub..... Where or What, gives you the idea that "without making horsepower" was a characteristic of them? You, like most out there... are completely devoid of how they actually function, and if you did know and understand... your jaw would "drop" in amazement.
By the way, the 6-71 was in production for 57 yrs, 7 months (Jan.1938 - Aug.24th, 1995)... Not, "75 years" (2013).... but still, literally and Officially holds the World Title for being the Longest Production run of ANY reciprocating engine in history, as well as being the most Reliable.
The 110 was also, every bit as reliable along with power potential and capability Far beyond what it was producing during that era, and was massively "over-built" for that purpose, however.. division "heads" wrongly decided to drop it from the line-up in 1965.
It was truly "an engine ahead of its time" in terms of power capabilities... such a shame that the metallurgy of the era in transmissions and drive-lines for HD On-Hwy trucks had Not yet caught up to it.
Your comments are of a fool. Back in the day, when a 230 horse engine was all anyone made, the 238 was king, leader of the pack. My dad had a 61 Mack with the 230 turbo charged Mack engine, and his brother had a 238 in his truck. The 238 walked away from the Mack in every situation, getting better milage than anything on the road, cause it burnt 98% of its fuel, instead of blowing it out the exhaust. You are comparing a 75 year old engine to modern technology and making fun of it. The 2 cycle Detroit built modern America. Give it its dues. By the way Mr know it all, Cummins is building that engine again, to go in semi trucks in 2025....

😂 Well, that was fun! I’m retired now but for most of my working life I ran large stationary diesel generator sets (Air Force & public utilities). It’s been so long, I don’t remember model, displacement, etc. but we had these two Nordberg 1000 kW units that were 7 cyl in-line 4-strokes. I think the cylinders were 18” diameter with a 32” stroke. Roughly 13’ from the bottom of the oil pan to the top of the rocker covers. Nominal speed was 327 rpm. They were a ball to operate. The cast iron pistons were prone to breaking around the ring grooves. It happened to me one time. What a racket! Two crankcase explosions in rapid succession filled the plant with thick black smoke. They had spring loaded crankcase pressure relief valves or it would have detonated. I ran out the side of the building and had to re-enter to shut it down at the front of the engine. The mechanics said the CC explosions were very minor. What a rush! The serial numbers were 3 and 187. The first two built were sent to a Texas oil field where one of them exploded and killed every man on the crew. After that they installed the CC pressure relief valves. That was in 1948. I worked there from 1983 to 2000. After I left, they closed the plant. It’s too bad. Should have made a museum out of the place. Oh well.
The most awesome stories in the comment section thank you
Thanks for sharing!
Man, when they run away get away!! I tried to stop an 8v71 with a clipboard over the open blower. It didn't work. Engine sucked in like a log chipper. Then we ran away. Boom n bang.
i felt sad to see this engine being destroyed . i like your videos i will stick to watching your engine rebuilds no more runaways for me . cheers . yes i am an old timer
Yeah, kind of sad to see something get tortured to death. I guess it was destined for the scrap yard anyway, but still, would have been cool to seen it in an old vintage boat or running an off grid generator.
Great way to de-grease an old Detroit, just bake it off! Great vid, amazing she held on that long with no coolant.
I have a 1954 Greyhound coach, with the 6 cylinder. I am extremely impressed with the power of that engine !!! I had no idea !!! Way to go DETROIT DIESEL !!!
Those things moved so much air that they could self cool the liners while revving to the stratosphere. As mentioned before, the rev limit when full-rack is usually valve float. Would be cool to hear one with a Jake rev and throw the jake:)
THAT JOKER IS BUILT TO LAST. HELL YEAH BROTHERS. ALWAYS DOING IT FOR DALE EVEN IF IT IS A 2 STROKE DIESEL!!
HE'LL YEA BORTHER!!!! WATCH OUT FOR CIBBINS
HELL YEA BRUTHER CUMMINGS TURBO DIESILES ARE SHIT BROTHER DEETROIT SCREAMIN DEAMONE DIEZELS ARE THE BEST BRUTHER GOBBLES
i thought it might just melt into a pool of metal .
CRANKIN THAT CUBBINS EVERYDAY BORTHER AMEN
Jesus relax captain America
Aww hell yeah man I love the sound of those! Just pure 'Murica right there... oooh i can almost smell it, too... awesome. Just.... fkng awesome I think. Almost comforting in a way as well lol thanks!
My last boat had twin 6-71 turbos, they ran beautifully. After 700 hours of use, I never had a single issue. When I sold the boat, they had 1,900 hours and would barely blow a puff of smoke upon start-up (normal) and ran clean. I used Lucan during oil changes and it stopped the oil burn. They are EXCELLENT engines. Change the oil and fuel filters and they will run for ever.
If I had a boat, there is only one make of Diesel engine I would have... DETROIT. You can rely on these engine long after others have given up.
We had 4-71,s as generator engines in our tugboats. they reliably made atleast 20,000 hours between overhauls. Darn good reliable noisy work horses!!!
Greatest diesels if all time! Got a cult following for its simplicity, ruggedness, amazing sound, war heritage and smoothness.
Detroits are timeless classics. They deserve a full restoration in a truck or mounted in a man cave an run with the boys over a beer!
Amen ,they were some TOUGH engines
I am a retired diesel tech of 40 years. That inline 6 71 could have been sitting for over a year. I worked for a company that was shut down for 14 months. Had to get several trucks started. Installed some batteries in a truck with a 6v 71. It started with only 1 revolution. Now of course, if it had been cold out that would not have happened. Now the older 6 71 ,if it had an injector stuck in full fuel,it would keep the other 5 in that position and run away. The newer ones had what was called a broken backrack. That would allow the other 5 injectors to return to the no fuel position.
I can be the only person who feels sadness while watching these videos. I just tell myself it's for science and proceed to "believe" it's justified.
As a Detroit Diesel owner I won't watch someone destroy a good motor. I know several guys that would have been happy to have that motor
I agree, kind of senseless. I think KT must have burned ants to death with magnifying glass when he was a kid .
@@georgesherfick2444 lol, I didn't even do that because burning alive didn't seem like a very nice way to go out.
It's a damn waste is what it is!
Nuff to make you sick. They still use these why wreck it?
Discovered this channel last night. This is my 5th video watching. This dude is very knowledgeable about engines. Very impressive
Will that engine pass ca. Carb😂
I am a Detroit fan, it was an 8V92TA that got me into loving the strokers. I know people are upset that this engine was tortured and killed, but there are literally millions still around that are in service or rebuildable.
I don’t know exactly why, but this type of entertainment never gets old.
They don't make these engines anymore and they are becoming extremely expensive for people like me who love the to find and work on them
@George Jones Hard to know where to buy something thats not advertised
The deepest evilness lying deep inside human's heart... To destroy and to torture for no reason but the most demonic type of psychological fulfillment - bloodthirst and sadism.
Overclocking and destroying a machine for fun is generally not against the law. However the purpose of doing it and the gain from doing it is nothing different from torturing animals or even human.
Thank You. That was spectacular, I would have never guessed it would have lasted that long, very impressed.
Goes to show there was a lot of life left on it. Built like a tank the 71 series.
Well…that engine spent the whole of it’s working life…giving the environmentalist a two fingered salute….in its final run…a Smokey outdoor …single finger one ! Great videos thanks
your delivery of commentary is every bit as good as anything you actually put on video-and i love all your videos. good to see ya man and look forward to the next one
I agree his wit and humor is something i enjoy
100% agreed there.
I agree as well. This channel is awesome. Gotta love all these crybabies whining about blowing this thing up.
My first truck was a freightliner with 71 v 8, next one was a 8V 92. Love the sound.
This is really cool seeing how the parts of the engine can work independently of the entire vehicle! Thanks for posting this!
I worked on the Detroit Diesel 53,71 and 92 series assembly line from 76'-83' performing different jobs,pushing pistons,dropping cranks in,pushing cams,setting timing etc. There were a couple times that some of us were taken back to the engine test area and were shown what happens when somebody didn't torque the piston rod caps properly. It's not pretty when ya see a rod poking through the side of a block.
In the 1970's I drove an old 1951 GM 4103 coach with a 6-71 and a 4 speed tranny. I come into work one night and the boss/owner takes me aside and says he's putting me into a coach that night that was just rebuilt. He said take it easy on her, the dashboard oil pressure gauge registered zero but the engine compartment gauge showed 8 psi. I make it the 67 miles out to the turnaround point, but coming back home about 20 miles into the run while pulling a fairly decent hill the engine developed a dead miss. Had to downshift to third to keep going as no room to pull over anywhere. Engine starts missing on a second cylinder, and loosing speed fast. I downshift second gear trying to make it to a wide area just up ahead when heard a loud bang and she went dead. Kicked in the clutch and tried to roll to the side as much as I could. Got out and walked to the back ending there was a river of oil flowing down the road. There was a huge hole in the lower side of the block where #4 cylinder was, and it tore the oilpan half off. Stuck there for the rest of the night until the boss arranged to have a hook come out. I guess even these "indestructable" 2 strokes won't run without oil pressure!
These stories make me sad because i'm sensitive to that lol
Had one run away at the Hills Ave Ryder shop in Atlanta. last time I looked there were still holes in the concrete blocks from where it came apart.
Lovely guy and test, especially the introduction with a crashing tour bus😂
Holly shit! I just gained so much respect for a Detroit 2 stroke after that.
Yet my friends can’t understand my interest in Detroit engines. They were built to last, I’m sure with a little bit of brain power we can figure out a way to make it have more power than a Cummins.
Keeping things simple goes a long way but is long gone in modern equipment.
@@butchpotato1804 feed it more boost than a cumstain cummins can handle!

👀would have loved to see engine temps with an IR thermometer: block heads,manifold, etc.... still impressive as hell. Nice job. Always a pleasure. Thanks.......
yea, he did a teardown and it ran so hot the the manifold did crack and some other damages, but other than that it did turn over and held together at the end of this video
This dude's content puts a smile on my face.
As always
Oh hell yeah. The comment section is always gold.
Me too bud!! I get excited lol
*They used to put these old 6-71 and 8-71 engines in many trucks, buses, and boats back in the 80s and early 90s. You can't miss the sound of one of these engines hammering down the road, like music to my ears.*
That 6-71 a real trooper. Went down with a solid fight even with all odds against it
You need a infrared thermometer for these events. I can only imagine how hot parts are
Damn that’s a tough engine. I miss hearing those things. Would have loved to have that one lol
Just OUTSTANDING!!!! I mean can we appreciate what this Detroit just did?! It served a long long life and then gave us a spectacular ending that no new shit could come close to……. WOW WOW WOW 🎉🎉🎉🎉
I worked on the 671 back in the late 70's to early 80's in the Navy.
Love that engine and it's sound. Operated "pusher boats " in Subic Bay boat pool. Had two 671 Detroits and even an LCU from WWII with 3 of them for propulsion and 2 471's from generations. Lots of FUN.
It was interesting to see you run that one so long and not see it fly apart!
Very COOL. thanks for the video. Brought back a bunch of Good memories. 🇺🇲👍
Did they still have Deltics there or had they gone by then?
subic bay is a little city now, still have go through the guard gates. did you ever venture out to olongapo or san marcelino?
@@bikeman5
Yes I've had to go through the gate and across the bridge over "shit river" too.
Don't remember the name san marcelino right now. Was that just north of Olongapo?
Some friends and I rode our bikes down to Angeles close to Clark Air base because there was no curfew there. Partly ALL night there! LOL
@@mathewkulczyk1645 yes sm is just north, i fly into clark 2 hour drive by car to sm or subic, u must have bike from clark to angeles
@@bikeman5
No, actually I was stationed in Subic Bay. It was a small town back in the late 70's.
We rode the bikes to Angeles from there to party.
I'd ride in to SM as you put it from Subic where I rented a house on the beach where a retired Marine owned a bar and rentals. Very Cool place. It's been a few years so I think that's the place anyway.
I did this in Iraq to 2 hmmwvs with the old 6.2 in em back when our government didn’t leave good equipment for the enemy to use. No oil, no coolant. They ran for over 45 minutes until they slowly died. We were able to start them back up after they cooled down but not for long

@@ChicanoOne760 Hey man I was just taking a shot at my old boss while reminiscing on an old story. I never mentioned any sides or why I think one is better than the other.
Best comment ever !
I "thought" we had free speech.
You literally had to turn the oil into steam with the patience of a Monk to make that thing "seize"...my Lord what and incredible piece of engineering!
I need an 8 v71 and a 12 v71 to through outside and run . Reminds me of my dad's trucks he had back in the day. Don't worry the neighbors will love the music . They don't have a choice
Just like Deboss....the old Detroit Diesel guy said he'd never seen one that wouldn't start that didn't have something sticking out of the block...amazing they don't seize! Theirs was a 16V though.
that's amazing how much that engine took and did not lock up ... that could still be easily rebuilt. insanely tough
And this is why I love old Detroits let alone good old engines, they're tough as nails and hard as hell to kill em off.👌
Yep, I worked that engine in the Air Force.
Try doing this with a modern engine they'll go within a few minutes.
Inline 6cyl engines (iron blocks) both gas and diesel are usually much more durable than other configurations. Great vid!👍
Easy to turbo and super charge!!
inline 6 2 stroke yes!
For all those too challenged to educate themselves on the ordeal with doing a runaway on a sack of shit that burns oil left and right with so many hundreds of thousands of miles of wear within(the kind that would cost a hell of a lot more to even attempt fixing compared to buying a new one), there are three things you can do with it. Melt it down for the metal at the scrapper's shop, make it runaway then use it for an ugly yard ornament or melt it down, or just leave it to rot. What I'm trying to say here is that this is the funnest way to handle nearly every engine on it's last leg. If anything, I see this as more of a glorious send off to celebrate the amount of Wonderful things the motor did in it's life.
Better said as going out with a bang.
Excellent video, very strong engine, it held up very well with no cooling. Please keep posting more of these engine vids. Thanks.
Its Rodalco2007! Love your channel m8!
That was amazing I didn't know the 6-71 could sound that good past governor, especially with the fire coming out of the exhaust, I have to say past governed full throttle, this has to be on of the most amazing sounding diesel engines ever. Now that 8v71 I liked how the blower sounded like a 4 stroke with the fan on , but that 6-71 takes all the gold in my opinion.
If u love this sound u should hear a gm emd locomotive at full throttle with a 645 v16 2stroke basically the same motor but alot bigger they have a heavenly sound they come both turbo charged and non turbo charged best sound in the world
Drove a 6-71 that the company mechanic turned up the governor to 2600 rpm. He was a Mack mechanic and hated Detroits and wanted me to blow it up, but it lasted the 3 years I was in it, and it ran strong! Would out pull a Cummins 290 in the fleet, and ran circles around the many 237 Maxidynes we had. It had a weed burner horizontal exhaust that would throw an 18 inch long flame at high rpms, lit up the bottom of the trailer, so the boys gave me the CB handle Wildfire.
The good old days...
I agree!
I wholeheartedly agree!!!!!!!!!!!
@@jimbruneau6769 Awesome!

Thanks for the time you put in to let folks like me learn about how diesels work- and come apart. You are a good, clear explainer for the new and ignorant.
Side-by-side to one of the caterpillar engines. See who wins. Let’s see who is re-buildable!
that is not worth of work and money
Hell yeah man compare the two side by side
Just to see not to fix after the fact!! How bad each 1 was like real world will help to save people's lives when they depend on equipment to not cost so much to fix at the end of the day !! Well that's why I would like to see and know !!
@ Frank Kreyssig Nah he is scared that the Cat engine gives up earlier than the GM. Now THAT would make this Cat hugger look dumb. It's almost like this guy has a share in the Caterpillar company. The only good engine in his word is a Cat but i guess Cat cares Just as much about him than cr*p under their shue's
Those were the good old days over the road rigs working trucks coming into the shop for service tune up or engine over haul miss those days and working on all Detroit's and other diesel engines😍💯🙏😎💪 got to give it throttle
Dude! The environment! Bwah ha ha! Thanks for the entertaining video. I can only imagine that if you'd hooked up a cooling system to that thing and a bigger fuel supply, it could have run for days. Incredible.
That ol’ 671 in my grader is still running strong .It’s amazing how much punishment they’ll take .
There might be some parts for you with this fellow... Not many but, some.
I know you have plenty of these old Detroit’s to destroy it’s great to whatch I use to run these same engines in the trucks I drove and had to fix back in the early 80 and late 70 on the road and the farm always loved these screaming demons keep em coming thanks agin for sharing
Thought for sure you were quitting yt altogether. Glad to see an upload, even if it’s few and far between just makes it that much better.
Always makes me a little sad to see an old detroit die in your videos but still very interesting and impressive, and I usually learn something.
Shame I can't get one here in the UK id love a 2 stroke detroit v8 to rebuild and use
I bet they exist there. GM made millions and our military spread them around the world. Plus GM exported them I'm sure.
Yup and this guy is blowing them up and dumping them. Theres millions of them that were made, but they dont make them anymore and never will again. So fuckin sick of the newest generation of gearheads, too many have no creativity and blow shit up for no good reason.
I'll just use that method of removal, on that air intake. that's what I like about KT3406E. he tells it the way it is.
I was an OTR truck driver and I was taught to never lug a Detroit. always keep them wound right up against the governor. but this is a demonstration of what happens. when you take them into the danger zone.
That old Detroit got a mean 2 step!!
Dang old Detroit tough as hell and that's why I like them, overrevved ran low on oil, overheated and gets crap fuel mileage but damn if they won't always crank up and run and do the work you need them to do.
Unless the temperature is anywhere near 0 degrees or less. Then good luck.
The 92 series was a an improvement over the 71 series engines. but now they are all outdated. but back in the day they did the job. they left my ears ringing more than a few times.
Glad to see you uploading

Only with the perfection of the harmonic balance in an I6 can you run a 1 Ton engine to full RPM teetering on top of some wood blocks!

Got me into runaway diesels
Thank you my man
I work on a golf course and have some engine repair experience
My course has a mechanic and he is certified in diesels
So we have an old Jacobsen 5111
We had the authorities come and ask us to clean up our old units
So I asked my boss if we could induce a runaway or overspeed
He said sure
So this Friday I'm going to try to get her to runaway or blown up
I'll post video
Don't blow up a perfectly good diesel just for the "lulz". Those Kubota 4cyl diesels run forever and there are plenty of people who would pay good money for it.
@@johnfox3845 it's shot
We had it on turf net for a year no one wants to buy it
So before we take it to the scrap yard let's have some fun
I can't do anything until after October 16th
I have total permission to have some fun with this engine
@@inrainbows1829 If the engine still runs, there are numerous people who would buy it, regardless of how worn out the rest of the machine is. If you listed it on Craigslist or Facebook Marketplace at a reasonable asking price, someone would certainly pick it up.
While the market for a worn out Jacobsen 5111 is likely to be quite small, the same cannot be said about a running Kubota 2.2l 4 cylinder diesel. There are always people looking for diesels of that size for many different applications. Hell, there's even a market for the engine in non-running condition, as long as it is rebuildable.
Deliberately destroying an engine that is in demand makes little sense.
For the sake of curiosity, in which state do you reside and what is the asking price?
I know it's late. Make it run as fast as it can!
Perhaps next time you could give it coolant, and connect the crank case breather to the intake, and also advance the camshaft 1 tooth. Setup a remote controlled oil pressure reduction device in case nothing happens
Thanks for the videos that you make. They are very interesting and informative. Back in my days on the family farm, we had several Cat tractors. A D4, D6, D8 and the big guy, a D9. I always enjoyed driving them, at least for the first hour or so !! 😝😝
On our family farm in Washington state we had two D5 Special Application tractors and two D6 Series C tractors. I would spend 10 hours a day in them, seeding wheat, plowing, rod weeding, fertilizing, spraying 2,4-D.. You definitely needed ear plugs. The 6s were pretty powerful, but the 5s were almost as powerful and got the job done.
Finally another upload!!!!!
That lasted way longer then I thought. I was figuring we would see rods flying. Id bet it wasn't built on a Monday or Friday.
It’s damn hard to kick the rods out of a 6-71 because the rods are extremely beefy and the crank and rod bearing surfaces so big. Now the V series Detroit’s especially the 92 series they’re a different story
*than, not then.
If he wood have put on a radiator and had coolant in the motor, I don't think he cood have blown the thing up. It probably shut down due to heat melting things.
And I thought that the day of the week based assembly quality was only the domain of the Eastern Bloc manufacturing :D

The 149's and the big EMD's are equally fantastic
Wish you would fly apart something that was actually clapped out
Worn out 6.9 or that 8v71
That 6-71 seemed like it was a good engine considering no smoke and started easy
Exactly. Perfectly running old engines always end up in the hands of some dirtbag that wants to ruin it rather than fix the little shit wrong with it and sell it to someone that will put it to good use. Why do you think classic muscle cars are so hard to find. Too many assholes ruined good ones.
Oh come on, those engines might last, but that is also their problem. No power and guggling gas like a drunkard at happy hour.
I would like to see an older DT466 runaway video. Had one in a dump truck years ago that was turned up to 2850 rpms.
I drove a 3 car hauler (used to be a 4 car but they removed the number 1 spot head rack) it has a 2850 rpm turned up all mechanical and she just fuckin eats and goes. Thing can pull down a house and go over 100 like it was nothing.
@@BillyBigRiggah How many HP
Having run these mighty engines on tug boats and trucks for years, this was like watching the end of Brave Heart :( Poor motor was freaking hero!
Creazy how fast these 2 stroke diesels can rev up
That’s one way to heat up the exhaust manifold studs to get them out.
Love the video, but pretty happy I don’t live next too this guy.
God speed brother
I'm always a little sad to see an old Detroit 71 series go out. Good video though brother! If you have any spare parts like supercharger, injectors or anything else I'd love to see about buying them from you I've got an old Euclid 72-20 loader with a 3-71 in it.
When your doing something like trying to start a engine after it almost locked up use a combination of WD-40 and starter fluid to get it turning fast enough to start again because the reason it didn't start is it wasn't turning over fast enough
miracles happen... maybe... eh..
I think the batteries were not to strong either. Need good connections and high amp batteries.
Any inline-6 diesel is just...👌
