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 It was a outdated hospital genset.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.

Don't forget that nearly every small ( two stand) drilling rig had 6-71 pairs driving the draw works and and mud pump. When pulling pipe they would run flat against the governor for about 30 seconds, then idle for about 30 seconds. They would do this for hours on end, then while drilling they would run flat out for hours driving the rotary table. If they were lucky every few years they got a "Kerosene overhaul" The oil was drained and the sludge washed out of the crankcase with kerosene, then new oil and back to work. They were available from an army surplus for $550 each, or a joined pair with torque convertor for Can$1000. These were often brand new in original crates. A great engine , but the noise was enough to drive you to distraction!

[@ElLoco-b1q]

When I was working in drilling our mud pumps were powered by ancient Detroit diesel V8s. Every morning we would check the fluids and crank it on and let her rip sometimes for 15 hours a day every day. Awesome motors love the sound of that 2 stoke

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.

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!

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.

[@ik04]

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!

[@jetstream454]

Probably the standard roots supercharger

[@jetstream454]

@Rick Delair I was thinking of the noise it makes 😉

[@rpm371]

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.

[@colin8532]

Most beautiful sound in the world

[@jimdieseldawg3435]

Superb! 6-71 already my favourite engine sound ever but at 2650rpm and burning that cleanly, wow. Thanks for sharing 😊

[@PhoenixRising251]

2650 actually sounds like 5300 because it's firing double of a 4 stroker. I miss hearing these old screamers.

[@ern48]

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.

[@blindguy63]

Back in the early 90s I had my own international Harvester load star tandem dump truck, I think it was a 1200 series. It had a 6-71 Detroit, and 5 4 pair of transmissions. Every now and then the short piece of 4 inch galvanized exhaust flex pipe would rot out and it would be open exhaust. What a sound when fully loaded crossing over a bridge and coming down with the throttle backed off at 45 miles an hour! Sounded like the biggest pipe organ in the world on steroids! I love 6-71s

[@spnynorman5519]

You know, I never tire of hearing these engines. This one sounds especially sweet ...

[@donniee1934]

Worked on those for 4 years in the Navy. Love that unique sound! Best engine ever made

[@lesgaal4017]

Absolute Beautiful gm music no other diesel comes close to a screamin jimmy

[@daniellibich1376]

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.

[@stevestackpole6817]

30yrs ago when I was a young firefighter our Kenworth pumps ran Detroit Diesels. Open jump seats at the time. Haven’t heard that sound in a long time.

[@georgecrosscross8253]

The most beautiful engine sound all over the world! I love this! Thanks a lot!

[@senatorjosephmccarthy2720]

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.

[@fredsalter1915]

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.

[@leonardgilbreath9004]

My dad worked for an oil rig moving company in the 50s &60s and had 4-71s in their IHs and thier Whites had 6-71s and to this day I can still hear them no other diesel had that sound love the 6v92 and 8v71 sound 👍

[@stevenjohannesen88]

I have to ask, why did 2 stroke diesels get dropped from modern day trucks and buses?

[@deepcow]

Emissions and fuel economy.

[@deepcow]

That sound is so familiar.

[@stephenmiller5023]

When I worked at Hawthorne Caterpillar in San Diego in mid to late 80’s we held annual Truck Dyno Competitions, and one year a guy showed up with a 12V-71 in an old Peterbilt & man did that thing sing !! Twice the sounds of this one here in a building will really make you smile . Enjoyed this blast down memory lane , thanks 😎👍

[@keitht7546]

All I know that Screaming Jimmy sounds GOOD, ESPECIALLY when going down the highway. Great short video ✌🏽

[@grassblade63]

Some of my favorite sounds: Listening to my Harley, firing an M-60 and hearing a two stroke Jimmy under a load. :)

[@spikydipple]

Now you're just showing off! Love it.

[@clintonandrews1538]

If memory serves me correct, during WWII, the Detroit Diesel 671 engine was built by Gray Marine Engines in Detroit at the rate of 100 per day and used to power Higgins Boat landing crafts, AKA USN LCVP. There is a bar/restaurant owner on Detroit's waterfront who likes to race his tugboat. It had a Screaming Jimmy 671 that was needed for the correct restoration of a Higgins Boat. That owner exchanged an 8V92 for the Jimmy in an even swap. Needless to say, the Restaurant's tug is moving through the water at a slightly better pace these days.

[@arnenelson4495]

I've always loved the "busy" sound of a Jimmy! Great engine. Nice video.

[@ablam8]

That 671 nearly new. Will go another million miles, ha. I used to sell big roto tillers, and we mostly used Jimmies. Tried Volvo. We had one very used machine with the 6-71 that we sold. it smoked and ran rough for 10 minutes on start up, then did a days work. They were thirsty. Thanks for bringing back memories.

[@emeryk5227]

Best sounding 6cyl I’ve every heard

[@davidunderwood2576]

They used to haul heavy loads of grain with the screaming Jimmy's in Ford 9000s where I grew up. There was an intersection near my house where they would have to make a complete stop. They would shake the paintings off the wall when they went through the gears.

[@JesusTorres-qr1gz]

Man that engine sounds great, very neat idle, clean exhaust revs up smooth without hesitation, nice toy.

[@howardsimpson489]

The owner looks very happy too.

[@KevinBower-gy5be]

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.

[@jeffwhite9001]

Tuned to perfection, so clean burning.

[@mort8143]

Thanks mate. I grew up along the Hume Highway between Melbourne and Sydney, Australia. The sound of those two-stroke trucks will always interest me. 🇦🇺👍

[@Hogger280]

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 !

[@jessieharris8204]

Clean up high. Dirty down low.clean idle act.

[@joshs4594]

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. 🌟

[@gettothechase636]

And no soot coming out of the exhaust! That's nice!

[@kevinsnell1622]

These 671’s were in the old Crown Coach school buses back in the day. Manual shift made it even better. Music to my ears as a driver every morning. Loved it.

[@maggot274]

I don’t have any words for how great that sounds

[@johnrossiter3185]

Beautiful engines. Reliable, fairly powerful and with a heavenly sound. Long live the Detroit Diesel 2 stroke. ❤

[@AlbertAGhazaleh]

Love the sound of Lenny never missing a beat!!!

[@kevinsnell1622]

As a driver I will always miss the sound and feel of these engines. Especially in the Crown Coaches. Total beasts.

[@cobra02411]

That thing is tuned to perfection! Amazing!!!
