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 !
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.
@@grantw.whitwam9948 yeah that’s exactly what I thought! It could have been a freaking good engine if the admission was fixed instead of leaving it stuck wide open!
It was destined to the scrap pile to be melted down anyways. Nobody wants them. Inefficient, and heavy for their power. They were incredible engines for their time, but their time has passed.
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.
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
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.
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...
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!
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.
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 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!
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.
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.
😂 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.
*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.*
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 !!!
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.
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 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 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.
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 ......
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 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
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
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 was one tough old girl there want to hang on as long as she could 6 71 Jimmy was the first engine got to really work on my 20th birthday God that was a long time ago great demonstration I've only seen one run way before
Can’t wait for the smart-asses raising hell about why you didn’t dump thousands to restore it to its former glory. Keep up the good work bud! sending ya tons of love from Saudi Arabia
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.
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.
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 am a ASE diesel mechanic for over 40 years.. Detroit diesels are quick to start in warm weather. I had a truck that sat for about a year. It had a 6v71. . I Install to new batteries. 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.
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.
That's pure, solid, authentic redneck nonchalance there. You must be proud sir, keeping the Tradition alone, fighting hard against the fuckin progress.
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.
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 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.
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!
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.
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!
As some that used to haul gravel with a 8v71 in an old Brockway tractor, good riddance. My boss called them the "2 stroke joke". I drove that truck for a season before we repowered with an 8v92ta. The 8v71 could barely keep up with a Mack with a 238 and a 5 speed, it was even more embarrassing because of the noise. The 8v92 was rated at 435hp but a 350hp Cat or Cummins would walk away on any uphill. Fuel was 1 dollar a gallon when I drove and even then the 2 strokes ate like 30% more fuel the small cam in the other truck. They were cheap, we got the 8v92 for $1000 and put in pistons and liners. Otherwise my boss would have switched to a Cummins. Nostalgia is a funny thing. The one big difference that I liked about the 8v92 was that the turbo quieted that screaming a little.
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?
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
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 had a 671 run away with me one day. Until I got someone's attention, all I could do was keep my knee pushed into one of the rubber air pipe connectors that kept it slowed down a little bit. The emergency shut-off was frozen up. Finally, a coworker came and pulled the fuel shut-off. This was in the lower unit of an old truck crane. What happened while revving the engine it dropped a valve, and a valve keepper jammed the governor wide open. That's what happens with old junk. Oh yeah, I was only inches away from the fan.
"Dont forget too dislike and unsubscribe" my man KNOWS some people dislike him. What a shame this is for research purposes in case of a run away 2 stroke haha
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 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
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!
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.
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.
The old detroits sounded really cool, many people love them for that reason. There is uproar over ruining it but I guarantee if it was listed for free no one in the comments would bother going to get it. It has no practical use any more and people tend to greatly over exaggerate the complexity of modern electronic engines and "failures" while disregarding some of the faults these older engines had.
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)
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.
@@MrSpacelyy an 80's chevy sprint got 60+mpg with an old carbuerated engine. Most cars now days, you're lucky if you get 30-35mpg... there's a guy online who gets 40+mpg with an old carbuerated 302 ford V8 engine..... the whole wiring to mpg argument is absolute nonsense.
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!!☆☆
I didn’t think a DD would have enough compression to start without a blower, and removing an air box cover would be such a large air leak as to be like it didn’t have the blower. So, learned something new here!
@@zoggrog8823 yes removing that air cover does lower manifold pressure during cranking causing low compression and non sustainable power, this is why it didn't stay running and was smoking like a bitch with it off, too much fuel not enough air but the engine was warm so it was able to pop off a few times before choking out on fuel. The blower on a Detroit only makes up for lower than atmospheric air pressure and in terms of boost you only see max 1psi in the box but without that cover you don't get anything so it won't run worth shit just like in the video. These blowers don't work the same as they do on a smaller engines.
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.
6-71 in my opinion was one of the most reliable and versatile diesel engine every built. I’ve seen them used in all different types of use in the maritime industry.
You should have rebuilt the Detroit! I could have used it. They don't make much power but in one of my boats you can overload the shite out of it and it reacts the same as unloaded. They get you home and that's what they were built for.
You should have bought it & rebuilt it if you needed it. End of the day, I get that it's a shame to see it killed off like that but it only ended up here because nobody else put up the money for it. Also I think these vids are a good demonstration for those who don't know Detroits & think they're just oily smoky old leakers that make no power, to show what they're really about, taking all the abuse and coming back asking where's the second helping AND dessert? Would honestly love if there were more 2 smokes over here in the UK, I'd run one for sure.
@Damn patriot Man Forget it...The only thing he can do with a Detroit is blow it up and his fans would even eat this guy's Sh*t! Hell they would even fight over it who would get the most. 😂😂
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.
