As a truck mechanic I worked on quite a few of these engines in the 70s, didnt matter if you were going 2 mph or a hundred they literall screamed and the oil oh the oil they leaked like a sieve. good memories
Understood I got oil all over my screen
My brother was a D Diesel tech he always said if it ain’t leaking oil shut it down it’s likely empty
Driptroit Diesel
I know it’s not funny when they run away, well it can be. I fired up a 12V149 gen set and she took off, I was ready for it on the flapper. But have you ever seen a man try to run through a F¥cking wall ? 😂
I have taken care of a 8v71 for the last 20 years at a dairy that I have done the mantance work for. It was a outdated hospital genset.
Right now it has about 650 hours of total run time. Was a indoor/ marine unit didn't have a air filter just a screen over the intake to keep your fingers out of.
Only gets run approx 1-2 hours a month.
Don't leak any oil, temp has stayed at operating temp for 20 years. Ready to go on line any time.
Only trouble is now it's too small.
Please tell me im not the only one who notices how clean Lenny runs... no smoke at all.
Like a champ
Keep in mind it's not under load. Additionally with a super charger properly adjusting fueling on a mechanical pump would be much easier as it has a predictable charge pressure.
Exactly my thoughts
@@DieselRamcharger so Greta was angry without any reason at all XDXD
@@DieselRamcharger amazed by how well engineered these engines are :)
I don't know what's more impressive .. the sound of it and the way it runs or the fact that there's no smoke at all
There's no smoke because all the oil leaked out.
I drove an Attack Troop Carrier with two Grey Marine 671's in Vietnam. It was a converted WWII LCM where you had to handle 25 tons deftly using two D-handle four-foot joysticks. I would twist for power on each engine and shift forward or backward for differential thrust. You could pivot the beast very gracefully when needed. Like coming into a pier against a strong current. Many a night sleeping next to them while the night watch drove going up rivers and canals through the jungle. The 671 sound and smell is still hammered into my night memories. I remember dreaming about home then waking up to the nightmare - just the opposite of normal life.
28 years in the Navy. Worked on 671 and 8V71 engine. Landing craft to SLWT
What a bad ass story. Thank you
I have been retired forever, the taste and smell never leaves you... 🥰
I had closed captions turned on....at idle it said, "Hmm......" At 2650 RPM it said, "(MUSIC)"...... How true it is!
Mine said hmm, applause over and over then music, hmm.. Lmfao!
Can it be balanced and tuned to Rev higher.?
@@jtamsett probably but at any given rpm it already fires 2x as much then a 4stroke diesel.
Then there is also the speed at which a diesel-air mixture can burn. This is a limiting factor.
The speed at which the fuel can get delivered is a 2nd limiting factor.
I don't think we will ever see a diesel engine doing 10000rpm.
Holy moly have the auto-generated captions improved recently...usually it wouldn't decipher simple sentences 😂
Also 2:55 how it says applause 😂😂
Best diesel ever made. Used in everything from WW2 landing craft to bulldozers, fishing boats, fire trucks and farm tractors. Won our war, grew and transported our food, fought our fires, built our infrastructure, caight our fish, you name it. That sweet GM music was the soundtrack to our cityscapes, waterfronts and construction sites.
Back in the mid 80's when I went to diesel school, the class of 12 split up in pairs and our class project was to completely tear down a 6-71, including the rack, reassemble it, and start it up on the stand. Since there was no oil or water in it, no exhaust system, and an open blower without the air box and trip plate, we were only suppose to run it just long enough to idle it and verify the rack was properly adjusted. About a minute.
The teacher had made a steel plate with a handle welded to it to slam onto the blower in the event of a run-away to shut the air off. We got to the last motor when the shop phone ran and the teacher handed the plate to another student so he could answer it.
The last two guys started their motor and the rack immediately went to full fuel. The guy with the plate dropped it and ran like he'd been shot! That motor ran for about 45 seconds before before we could get it shut down! You should hear what a 6-71 sounds like turning about 5 grand with no exhaust and an open blower! Yes, we all went home with stained underwear!
aw yeah first starts with no oil my favorite
Ah yes
😂😂 Some of the old 4 stroke diesels would do nearly the same if the governor was hooked up backwards.
Ask a mechanic why oil drilling pumps were Detroit powered? He replied because it could run governed wide open 24-7. All naysers shut up.
😅
Detroit diesels make beautiful music 👍🏻👍🏻👍🏻
No engine, gas or diesel, will ever sound as wonderful as a properly tuned Detroit Diesel. I used to have a 6V92T in an Eagle and I loved going through tunnels or overpasses at 70 mph just to hear it run. Honestly I don’t think that the 6V92T was their best sounding engine but it was still sweet.
I can remember as a kid sitting on the engine hatch of fishing boat going out San Francisco bay with screaming Jimmy, at full scream. 40 years ago still can hear it today.
I think that's tinnitus today...
The sounds of San Francisco when I was a kid was detroits
@@willmetz1490 Pretty sure the Muni Rwy ran them. I lived in SF for 20 years. That sound and the smell of baking bread and roasting coffee down at Hill's Brothers.
Could listen all day long I don’t think it’s possible to be tired of the sound
Second that, honestly tops my favorite motor types. Other than VW W-Engines or high-rev V10's
Amen Brother! That is music to my ears!
This engine's will run for ever Dependable and simple to work No computer B.S or plastic need it Thanks for posting this video God bless You all
Until the fuel rail goes full send then u got trouble 😯😳
ok boomer
@@EATSLEEPDRIVE2002 what?
Ehhh fuel rack adjustment and injectors under valve cover make it not as easy as say Cummins early 6BT I would say have to be the easiest
Sim, é um motor simples é 2 tempos é melhor que 4 tempos.
Drove one of those screamers with a 13 speed for 12 years starting in 1971 . Hauled gasoline around western Pennsylvania , Ohio and NY. Exhaust had a 90 degree elbow just outside the passenger window and what a roar , loved it !!!
I had a buddy with an old Jimmy with the 8V-71 in it. He pulled a grain wagon and hauled corn and beans to the river from the farm. Another friend had a cab over Jimmy with the 6-71. He hauled scrap steel to a mill. It was always fun to ride along with either of them. Those motors sure loved to sing.
@@ronfullerton3162 which begs the question, why was your friend hauling beans and corn to the river? lol
@@mr.butterworth4216 I'd guess to put on a barge,for shipment.Used to pull a hopper bottom for Tyson.Saw alot of them being loaded.
Don Chastain definitely a barge. Rivers are used for this a lot more than people realize
Sweet exhaust!
What?
Growing up in Ca.in the 60's, we lived near the Cajon Pass and would hear those trucks going up and down the pass day and night. The sounds were incredible.
I bet that was a treat. Oh driving that pass with my learners permit the first time was daunting lol
Military used to have a lot of them, old pre 70s HET had 16V92 with twin straight pipes, that's why I still listen to them today.
I heard that a lot of the engines built for ww2 are scattered across the world now.
The M746 HET had 12V 71 in them. The later model from late 70s had an 8 V 92T in them. The older M123A1C had a Cummins 903 V8 in it.
I had twin 8v53 Detroit's in my Chris craft. It redlined at 2850. I ran them at 2650 when I was out on the water. Had to wear ear muffs when I went down in the engine room at those rpms. Incredible.
Growing up in the 1970's I used to hear that wonderful screaming Jimmy sound all the time down the highway. Thanks for bringing back good memories, loved it!
BrodieBr0 (
We had one back in the 90's at a company I used to work for. I didn't drive it,I was just the driver's helper. That truck was a coffee spilling machine. 😆
Sim, o barulho desse motor é muito bonito.
That was the sound track of growing up in the 80s too ✊🏽
Love that sound!!! And I see literally zero smoke!
Looks to burn super clean for a very old motor!
He just did an in-frame on it about a year ago...
That’s because it’s got all of the modern emissions, Government, and DEF systems added aftermarket 🤣
@@RustyZipper Not on an old thing like this
Yes I notice that too
Growing up in Boston in the 80s all the public transportation busses sounded exactly like that. Man that sound brings back memories.
I recognise the sound from a lot of movies of that era as well. it's unmistakeable.
I remember the public transit busses in Dayton Ohio all being Detroits when I was growing up.
Back in the 70’s I used to drive an International Cab-over with an 8-71 under the Dog house right next to me. No wonder I’m almost deaf.
It is clearly evident that Lenny is owned by a master 2 stroke diesel mechanic!
Agreed. Instant startup, super smooth idle en NO SMOKE at all.
Yep no smoke
@@natevanlandingham1945 And no oil leaks either 5 thumbs up😗
That is the best sounding running 6-71 straight blower I've heard in a long time. Used to be a popular logging truck engine back in the day. Really wicked with a Jake head, but necessary for mountains logging truck.
8V71 twin turbo'd has a real high pitched scream on a hard pull
Heard a 671 on a belt driven sawmill, straight pipe through the roof of the shed.😍
Hear it two miles away
First semi I drove, a Brockway. Long nose screaming jimmy. Loaded 40 ft. Trailer 60+ mph. Headwing maybe 50mph. Great trucks. Originals had wooden floors. Man brings back memories. 85 now missin. Last tractor 9670 Int. Cabover. God bless.🐻
Nothing sounds Sexier than a general motors built detroit 2 stroke
This, or any 16 cylinder EMD 567 or 645, non-turbo. Those are just much, much bigger Detroits, right? I'd even take the turbo 20 cylinder 645 of my SDP45.
@Rick Delair Awesome reply! I love the deep bass notes of the 645F and anything 710. I helped a buddy change out a cylinder liner in an SD45 a few years back. The pallet it came boxed in was crushed.
All EMD really is, is just Detroit Diesel’s Big Brother.
We need to get Bus Grease Monkey an opportunity to work on one.
I had to repair two CNC mills at EMD about 14 years ago that were used to machine piston pin carriers. The sheer size of the pin carriers alone was nuts!
Drove a fire engine that had one. Could hear it coming a mile away. Then hit the jakes brake!
A Jake on a Detroit? and Turbo? A 671 blower would suck a turbo down the hose and eat it.
Yeah back in the day we had garbage trucks with that engine and our landfill was on a young mountain and loaded with automatic transmission it never changed pitch of the engine , what a workhorse !!!
We also had a firetruck with a huge Detroit can't remember which one but it was a beast you could hear it miles away too
@@tomrobards7753 Ran a Gus Pech earth drill powered through a pto and hydraulic pump by the 671 in the Brockway truck it was mounted on. Get to the job site, put on the ear muffs, throttle it up, and run on the governor all day. Add 50 gallons of fuel and do it over again.
Music like bagpipes with the single remarkable tone always running in the background.
I was in high school in 06 getting ready to graduate when I learned of the detroit diesel 2 stroke. We had an old 50s or 60 firetruck in the volunteer fireman's class at the vocational center. I remember hearing that it was a 2 strome diesel and hearing it for the first time it blew my mind. Sounded like a high performance race engine more than a diesel.
Even at low idle I find myself grinnin' ear to ear! Thanks for the memories! :-)
The sound memory is incredible!? Like an old friend I used to love, and sometimes hated, had straight pipe just outside driver’s window?
O motor por ser 2 tempos sobe de giros muoto rápido.
Same here. I was raised in these then drove them and gosh the sound now brings a smile and tear.
@@edilsonmartins66538
Making me homesick, l drove Freightliners out of San Diego Ca for 8 years, straight V12 Twin turbos V12 and Turbo V892 Millions of miles 1972 to 1980
SING IT, LENNY! PLAY US THE SONG OF YOUR PEOPLE!
Gave me flashbacks to watching maximum overdrive when I was a kid
I used to work in the oil field. 671’ were on the Rigs. Their were left and right hand engines. They’d bolt two of them together. Had three sets or six engines with long strait pipes coming out. Those pipes were aimed highly at the mud tanks where you had to work sometimes. You talk about Loud !
They were all maxed out RPM’s.
I’ve pulled many of them out when they’d blow up !
I still wish I could go back to those days !
The 6/71 is my favorite Detroit Diesel, it’s music to my ears especially when going through the gears.
...and drive them like you are pissed off! They love it!! Our older fleet of fire engines all had DD 2strokes, fire them up cold, run the piss out of them, then shut em down, sometimes 5-10 tomes a day. They were dead reliable, plenty of power, and fun to drive. Our newer stuff, all 4 stroke and electronic, takes 30 seconds just to start(the computer has to go through all of its checks) then you only get a percentage of its rated power until its fully warm(they are all 450+hp and slower then molasses) they are constantly in the shop getting repaired. No bueno! The life of any fire apparatus is a hard one and these newer engines aren’t designed for it. Hey are made for efficiency over the road in a semi, not to be abused!
They were the work horse of the artic . Had an old farmer for a mechanic and one time he had to change the engine out in a Nodwell at 30 below and he used a Bell 206 to lift the engine in and out .
Absolutely symphonic to an old retired 100 ton master boat captain. I had a 46 footer with 2 671TA pumping out 485 hp each and the a 62 footer with 2 12V71 TT cranking out 790 each. Music to my ears…. That song, will never get old!!
I was introduced to the 6-71 when I joined the U S NAVY (6-6-61) @ it helped me to retire.👍👍👍🤛🤛🤛
You sir are totally unsupervised where’s Kelly
We'll have to get him the "unsupervised " shirt .
Best comment!
I laughed way to hard
Awesome 👏!!!!!!!!
@@Gerrit-Max "In my defence, I was left unsupervised..."
Most beautiful sound in the world
Without exception this is my favourite engine of all time. worked on these from 1980 till 1997 in marine versions from 3 53;s up to 16v149's love em all, great power, great engines
I was born in 1949 in Los Angeles. I loved to hear the diesel trucks and busses growl through the gears. In the mid 1960's, my dad commuted to work in SF in Greyhound busses with the split rear windows. Earth movers would howl as they scooped up dirt. In Vietnam, the electricity was generated by six boxcar-sized two stroke diesels. The smell of diesel exhaust was everywhere. In the 1980's, I got to visit a geothermal drilling rig near Clear Lake, whose power was provided by four boxcar-sized diesel motors. Great memories. Thanks for sharing!
Man that engine sounds great, very neat idle, clean exhaust revs up smooth without hesitation, nice toy.
Brings back memories of the old GM city busses, sitting in back right next to the engine, waiting for the bus to leave, hearing the steady thrum of the engine idling.
When I was a kid in NJ the GM city busses used to stop at the end of my block in the snow and ice. When the light turned green the driver would inch a bit out in to the intersection, turn the wheels left, and goose it. The chained up rear end would spin 90 degrees in two seconds and he'd slowly move off. Gotta love Diesel torque!
@@johnstreet797 that's a cool memory, but the torque is from lots of factors besides that it's a diesel. Any bus engine is gonna have lots of torque regardless of its fuel
The Detroit diesel - The most efficient device ever created for converting petroleum into noise.
My Dad had possibly the most stroked out Detroit ever. It was a 671 with 70 injectors turned to 2650. It would make a 290 Cummins cry.
Lenny just needs some turbo whistle to complete the orchestra. xD
Its supercharged were ya think Eaton got 671 from?
@@haroldstacy4748 it's not supercharging it's a blower and it doesn't have any affect to the hp its technically naturally aspirated
@@conner5611 is actually correct in this statement
@@IAmAnonymyz Yeah DD themselves referred to them as NA in their literature, and the blower functioned as only a "scavenger". I wonder if one could technically overpully them and get any extra power from it?
IIRC its a gear driven blower not belt driven
One of the ships I worked on had a V16 Detroit gen set which COULD be started remotely but I always started it locally to hear it start up and run up to 1800 rpm, a fantastic sound. Being a two stroke it sounded like a 4 stroke at 3600, being a V16 it sounded like a straight eight at 7200, fantastic
@@user-ff5ge7hx2c it was a gen set, 1800 working speed
They had an old Holmes 50-ton mobile crane where I worked, it looked like a huge tow truck. It had two Detroit diesels in it, one for the crane and one to drive it around. I loved the sound they made.
I have a 2/71 on an old Onan generator ! Still sounds grate , I once saw in Australia a Mack truck that blew up a 6/71 and all they had was a 3/71 , it was in that truck for 20 years , it did good enough job not to be replaced , no power of the 6/71 but that little 3/71 would not stop even on Aussie hills with 20 tonnes of logs on the back , but there was a lot of gear shifting going on !!!
I drove a quarry truck with a 12 v & that was a screamer. I used 105 gallons of deisel daily. A fuel sucking beast that just screamed.
Still gives me goosebumps...Thrilling sound of a roaring Jimmy!
Loved the sounds of those busses when I was growing up, this really brings back memories! thanks for showing this and letting us hear it sing!
In the ARMY in the 70s, we had vehicles called gamma goat. These used this engine, and after operating them for a period of time, you felt like your head would explode.
My father in law drove trucks with Detroit diesels and he was told "drive it like your mad at it and you'll never have a problem". He says the man that told him that was exactly right. And it sure was fun proving him right
I miss the sounds of the old fishbowls we had around here when I was a kid. Especially going up hills they just sounded awesome. These new NovaBus / NewFlyers they use now just aren't the same. Wish I had the $ to own a fishbowl bus love the style. Nothing beats the sound of a old 2 stroke Detroit!
James Woods The wonderful music that 2 stroke Detroit diesel plays is why I bought a 1980 mci mc9 with a 8v-71 to become my motor home after the conversion.
@@mikemcgrew65 I also loved the sound they made when they idled too, it would be like a little mechanical tune like a hummy repetive rhythm then the air would blow off and the tune would start over every minute or so. I miss those days haha. Fishbowls will be my favorite busses as long as I live. Would love to own one and turn it into a camper or mobile home.
Kind of shaped like the old White COEs, with a screaming Detroit Diesel powering them!
NovaBus sucks. I drive them now as well as New Flyers from 03 to 06(Best) and Excelsiors(Not weathered very well) and New Flyer Hybrids from 07 to 10(07, 08 not bad. 09, 10 not great). Would love to have a chance to drive one of those old fishbowls, just once. Even if it means I gotta get up to change the signs and I get a sore back from that stump they call a seat. Lol
I remember well as a kid hearing a cement mixer go by every day and thinking it had a turbine engine. It probably had turbocharged 8V-92!
Probably the standard roots supercharger
@Rick Delair I was thinking of the noise it makes 😉
I remember riding those old COTA buses when I was a kid, I loved it.
Every mechanical sound is amplified through the block for us to enjoy.
You know, I never tire of hearing these engines. This one sounds especially sweet ...
Oh man, that is awesome. Ever since i was a kid, i have always loved the way a two cycle Detroit sounds, especially the 671. Great American engine..
I once read a you tube comment that said, "it not leaking oil, it's marking it's territory"
Back in the early 60,s we purchased two 671,s at a navy surplus auction in San Diego . We the built a 52 foot cabin cruiser around those beauties. Great memories of my youth and early teen years.
Oh you bring back memories, when many years ago we used to service one of theses engines in a garage I worked at when I was 16. I liked it then and I still like it!
I grew up operating and rebuilding those engines in various boats we had. Then in college worked on and drove old GM transit busses for the Hollywood Bowl shuttle with those. Now I run a locomotive and a locomotive crane with them at a railroad museum. And still have two complete engines and a 2-71 generator in my Mom's backyard from our last boat.
The sound of a 2-stroke Detroit Diesel is music to my ears.
That engine sounds smooth as butter! Absolutely awesome diesel-ness! I was a welfare kid in the 70's and whenever our clan had to travel, it was via Greyhound (or sometimes Trailways). The sound of those engines in the terminal was music.
The most beautiful engine sound all over the world! I love this! Thanks a lot!
Love those old girls. They sounded beautiful! Really miss them.
I remember being younger and the garbage trucks had detriots in them. Always loved listening to them. And can't forget the grain truck using the jake to speed shift
I don’t have any words for how great that sounds
And no soot coming out of the exhaust! That's nice!
As a kid in the early 90's I rode Crown School buses to school and I will always remember that screaming sound those Detroits made under the floorboard!
The 71-series diesels are one of the best ever produced by anyone, anywhere. This one seems to be in good tune.
I've always loved the "busy" sound of a Jimmy! Great engine. Nice video.
All I know that Screaming Jimmy sounds GOOD, ESPECIALLY when going down the highway. Great short video ✌🏽
As a driver I will always miss the sound and feel of these engines. Especially in the Crown Coaches. Total beasts.
I drove Crown Super Coaches at Los Angeles Unified in the late ‘80’s and I would wake up every morning for the sound and smell of those engines. Loved the black plumes of smoke Crowns are famous for.
Now you're just showing off! Love it.
Nice! Gotta love the sound of a screaming Detroit. I've driven lots of these in trucks throughout my career from a 6v53 through 8v92, mostly 8v71's. When I was young an old guy told me to slam my hand in the door and then drive it like you are mad at it. I found that if you keep them revved up and screaming they don't leak as much oil.
I prefer 4-strokes but the six cylinder 2-strokes always sounded like a beast.
In the 1970’s Detroit Diesel told mechanics oil pressure was adequate at 1 lbs. pressure to every 100 RPM’s . That always stuck in my memory . When tuned correctly the initial start the engine would lope 3 times and then smooth out .
Superb! 6-71 already my favourite engine sound ever but at 2650rpm and burning that cleanly, wow. Thanks for sharing 😊
Love the sound of Lenny never missing a beat!!!
At the 2650 rpm point that great sounding Detroit diesel engine sounded so smooth that it seemed as if it wasn't working that hard. I am 70 years old and I have always enjoyed the sound of a Detroit diesel engine. Great job.
Absolute Beautiful gm music no other diesel comes close to a screamin jimmy
With the few hope there is debates over the Cummins 6BT that turns diesel fuel into noise and smoke when those believe a screaming Jimmy comes second.
That thing is tuned to perfection!
Amazing!!!
In the Air Force those Detroits are still in our -86 generators and hydraulic test stands. On the hyd test stands we would get them up to 3000 rpm-awesome sound. Our AGE just doesn’t sound the same with Cummins, Hatz, or Duetz engines
I remember when those buses were cruising up and down I95 when I was a kid.it’s music to my ears and good music should be loud.
Terrific video. Gold star. 🌟
Tuned to perfection, so clean burning.
I want everyone to notice that the exhaust is clean and no smoke when revved up - if you do that with a four cycle, even a tier 4 engine, you will get smoke !! Yet, these jimmies were bad mouthed for being dirty and can't pass the emissions tests !
Clean up high. Dirty down low.clean idle act.
Some of my favorite sounds: Listening to my Harley, firing an M-60 and hearing a two stroke Jimmy under a load. :)
Early 70's I Listened to way too many country songs about truck driving. Got my licence and drove a 318 13 sp KW cabover over the rockies. That was enough for me. 🤣
What a beautiful scream!!
Burning surprisingly clean. Love that sound!!👍🏻
FANTASTIC video. Just think - of the millions of diesel engines produced by dozens of different manufacturers over many, many decades - how many of these engines can be identified just by a truck or a bus driving past you? One. Just one.
I just drove my new to me...1955 GMC Buffalo home... she's a beauty. Total custom with no smoke and not one oil leak on the "Screamin Jimmy". I am a happy camper! You sir are the reason I bought it. Love all your vids!!!
I was in court in the late 70s when the head of Thurston Motor Lines shop swore. Under oath that there is no such thing as "governor" on a Detroit engine.
Not much of a mechanic was he? Oh wait, he was head of the shop so most likely not a mechanic, just a pencil pusher. And the jury was hanging on every word of his testimony. Hope the opposing attorney tore him up
Listening to the sweet music here in Ireland, beautiful!!
Air compressor dealer I worked for years ago had to 850 CFM Sullair screw compressors. They both had 6V71s in them, loved listening to them load up and roll coal
It's working with its pistons all working together, so it's so smooth. That diesel lasts so long partly because of it's smoothness in all power pulses. A masterpiece.
OMG had the chills the whole time that Jimmy was a singin
Love the sound of a 2 stroke Detroit 👌
