    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.

    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.

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.

    😂 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.

    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!!

    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....

    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.

      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!

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.

It didn't even make 1 revolution and it was running.. I have had a inline 6 71. In a boat that had been running , and I had a 3/4 ratchet on the crankshaft pulley bolt to turn then engine over to set the valves. My only mistake was to not hold the shut down in the stop position. Of coarse it started. Lucky that the ratchet did not jam.

    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.

      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.

    In 2018, I took a 1978 37C Hatteras with twin marine 6-71s on a 3,000 mile journey. It was risky and we had a few glitches but those engines just worked.
