I have been watching your videos for about 6 months, and I could not figure out what it was that really set your videos so far apart from all the others then the other day watching some of your older vids it hit me. Your channel is a modern-day Andy Griffith show. Clean, funny, family safe, good morals, you all treat each other good. The way you work together have fun, it is all just such a pleasure to watch.
Any wife that demands you order parts for your blowed up engine "TONIGHT !!!" is definitely a KEEPER. I watched the whole build..so sorry for your loss.. you can bring er' back to life .. i have no doubt.. I'll be watchin..love the channel .
I think I speak for all the Sleeperdude fans when I say we are so proud of ya'll! Seeing those kids smile at Dad doing a SICK tip in was priceless and ya'll will come back bigger, better and a SERIOUS burnout contender!
Bedankt. Hier is alvast €15,- Voor het $23,- Onderdeel wat je nodig hebt. We vinden jullie familie echt leuk en hebben nu een lifestyle. Waar ik zelf van droom. We hebben allebei een zeil achtergrond. En, zouden gaan zeilen. Maar een spierziekte, bij Gabriëlle. Is de reden dat we 25 jaar nog steeds op de zelfde plaats in Nederland wonen. Greetings from Spakenburg, the Netherlands. Gerben T and Gabriëlle. P.s.Soon, you will have real Netherlands work boots.
🔧 The reason for the Extreme vibration is the slime you had in the Casings.. you should never have liquid of any kind in there unless it's to get you home or in a lawn Tractor 🚜 Even if you never balance your casings at least keep them dry inside 👍
Josh, a few things that may help...if it's too rich at idle and part throttle, the methanol blow-by can significantly dilute the oil and by the looks of the oil when you drained the pan, I'll bet there was some methanol mixed in that oil. On WOT you may have been too lean which would help to explain the combustion chamber damage. I couldn't tell what kind of PCV system you had, but it might be good to use the large base port on both carbs with dual PCV valves and dual breather elements on each valve cover to help evacuate blow-by. I would also definitely take some time to tune ignition and fuel-air across all RPM's. Hypereutectic pistons will not tolerate too much ignition advance because of the brittle alloy so I would go conservative with timing advance since you don't have an active knock-sensor/ignition retard system. Good Luck!
Your daughter deserves a lot more credit dude, I no Ralfhys your boy but that girl is in there elbows deep. Doing more work them most. Just saying we hear Ralfhys name quite a bit, your girl only works for daddy's approval.
Many concur and I've sent a comment directly. Hopfully Josh will appreciate the crucial importance of this. I don't want Josh to feel beat up, just to know it can make or break a child's spirit.
Ralphies knowledge on engine parts for his age leaves me speechless. Going through older videos and watching the kids learn and soak up all that information is really nice to watch
MAN ! You guys have an awesome thing going on there. With a family like that there is no losing ; just winning at different levels. You are blessed . Your videos always make my day.
Josh, you need to put a Nader style shutoff valve under the hood. You need to shut the valve off and run the motor out of fuel. Racing alcohol will go past the rings. I used to run circle track cars and the fuel gets milky really easy. Also you have to run at least -8 fuel line. If you are running 3/8 line, you are not feeding enough fuel. You burn twice as much fuel than gasoline. I used to run a single 750 carb on a 13:1 406 sbc and I believe I had like .140 jets.
I don’t personally know but I’ve read that methanol runs lean and the best way to tell if you have the right mixture is with an oxygen sensor to read the exhaust gases.
My personal prognosis is it went lean on one carb, probably due to the bowls running dry (looks like it was the rear one). Maybe you should go to a swirlpot design with two holley blues sucking off that and a separate reg for each carb with a return system rather than a deadhead setup..
You need to remove all the bearing including the cam bearings and have that block cleaned out for there is now metal particles in every part of that engine. and mic the crank have it polished. This is why I never ran alcohol in my engines. buy good racing fuel. I wish you the best on the rebuild of this engine.
My wife and i love your channel We are from Gatlinburg. We moved to California 2 years ago to go to rehab. We have been sober now for 2yrs. My wife just recently saw your channel and fell in love. It reminds us of home. we are doing wonderful here. I work at a rehab now. Watching your show takes us home. So pls keep the great content coming. " pour one out for your homies"
Geez Josh....you seem to have the worst luck with burnout cars..two awesome (and expensive) builds and two 30 second blown up motors to show for all that amazing work you and tour awesome family put into it..IF u add in the motor homev it just doesnt seem fair.I can't say enough about how cool the Gremie looked and how awesome she sounded..I really hope third times a charm!! The Slerperdude family deserves it..thank yall for all you do.. love the cars the fam ..the animals and the shop!!!keep it up guys!!
No way Jose. Plum is the maroon family whichstarts in red and runs into pink. Purple on the other hand starts in the blue family and runs into pink. 2 very different base colours BLUE & RED !!!! That was def a shade of PURPLE !!!!!
I love the fact that WAWA and Ralphie are as into cars as much as ‘Dude. This is one of only two or three sites that I always watch all the way through. Very entertaining. Love to all!
Well, at least it did not break at the track. Inside the garage was unreal. Can’t wait for the Bristol Event. Know you will get it. Ralphie,Wawa, and mom keep you going. Thanks for sharing! 💯👍👊
And be darned sure the amount of initial and centrifugal advance is appropriate for the methanol. Glad the engine was not hurt worse. And you did good at the competition!
That's very unfortunate for poor Grem but you guys will get him up and running again. We really appreciate all the time and effort you guys put into these projects and videos they never disappoint.
Might build her little more in the loose side this time. Think they tighten up running like that for that long. That tunnel Ram is a barrel for every cylinder. Might do some individual tuning, depending the top. 🤔 might run it 15, then 30 , and work your way up and tune as you go. You’ve burned the cadmium off all of them, looks like lean, and like you said, your going for so long, just keeps getting hotter. Think you did pretty awesome considering the time frame lol. She got put right together and was gone smoking tires, right quick! You’ll get her figured!
Josh, My family has a background in truck and tractor pulling. We run methanol in our puller. My Dad and I watched your breakdown video together and had a few ideas for you. For a methanol setup expect to run twice as much fuel compared to gasoline. Gasoline is 14 to 1 air fuel ratio and methanol is 7 to 1. We'd recommend using forged pistons and maybe inconel exhaust valves. The 360 the heads are limited , consider a 440 if possible. Also methanol always gets in the oil, get used to changing the oil after every event this is normal. Consider cutting about 12" to 15" off of the headers, that should bring up the R's.
This is so incredible how both kids and Josh know what to take apart to see what's in pieces? And they are very interested in what's wrong with it? Love this show for that!!
If I had to guess I'd say your fuel system couldn't keep up. When I heard it die my first thought was running lean and melted pistons. That's definitely all the signs of detonation from specks on the plugs to beat up top half of the rod bearings.
The torque converter 🍩 could go down in the history as another one of the great color controversies of all time along with “the dress” from a few years ago. At first i’d of said it’s purple but after doing some research outta boredom it’s a tough call because there’s pictures where it definitely looks purple as well as picture where it definitely looks blue. 🙃 Oh well you still did a great job, the car did awesome up until it didn’t. To do all that in a the short amount of time was amazing so I have complete faith you’ll get it back together. You all are awesome!
Conveter was in Led's shadow initially, then moved out into Led light. So that's at least 3 different variations in colour temperature! Plus angles, individuals eyes. A whole basket of variables - weirdly!!!!!!
With 13.5 compression ratio and a lean mixture, it should have blown sky high. A hemi may tolerate that a little longer,a but never a wedge. You may want to try 10.5 to one next time, richen it up, and please have the engine finally balanced. Running wide open with an unbalanced engine is a formula for chaos! Still very much enjoy your homespun videos, and kids always pitching in. You're an awesome Mom/ dad combination.
Yeah this was what I think it was. The vibrations from the unbalanced assembly at high speed would have been sending shockwaves through the engine when running over 5k. Something was going to fail. And if a carb was lean, a little heat, with some extra vibration that causes more heat... That machine shop, couldn’t get around to balancing a crank, boy they deserve a special place….
I did failure analysis on components for the space shuttle for more than 30 years. Failure analysis is one of the most challenging and interesting things you can do. You can’t help but feel like Sherlock Holmes when your working a difficult one. Love the looks on your and the kids faces as you discovered each “fact”. Looks like you might have two future metallurgists on your hands.
The oil sprayed everywhere was what I was talking about that you need catch cans for the breathers so it won't as you're spinning around/at high rpm. When methanol goes lean it will burn hot.. Again, I said it in a previous comment, that's down to the floats being that angle when you're spinning around.. one side is getting flooded while the other side of the carb/engine goes lean. Not having had that engine on the dyno or having EGT sensors in each runner is part of what killed it.. You have no clue where the fuel is going. If you watch Engine Masters they often have to have a different jet at each corner of each carb with tunnel rams because they distribute fuel in weird ways. EFI really is SOOOO much better when messing with methanol or nitromethane. You need to be able to tune each cylinder separately and know exactly what's going into each hole. The valve cracking could've just been down to a manufacturing defect. A piece of advice, when you have a blown up engine, don't turn it over on the stand.. take the pan off the way it sits, when you flip it over you're just dumping any pieces of metal into the engine. Your biggest problem is the simplest to fix.. you don't have a shelf full of broken parts.. You HAVE to have a shrine for Tributes to the Gods of Speed. Learn from Burt Munro. (if you haven't ever watched World's Fastest Indian you're missing out.)
@@Sleeperdude yes and thanks for the tip on the USS Cairo. I just completed a month long road trip and filmed the Cairo (acknowledgement to you on the episode). Love that history 👍
Love this Gremlin series Josh! It's more interesting to see what can go wrong sometimes than to have everything go perfect! This is entertaining like that scene in Apollo 13 when they fly by the service module and see the damage and also all the problem solving they did! Two thumbs up! Sleeperdude family
Josh I had a friend used the same pistons you used in a neon and within 1000 miles they shattered and messed up the block his next build had stock pistons and it’s been 3 years now and still running it
Mr. Sleeperdude, your videos are addicting to watch and reminds me so much growing up with my dad and his cars.....Consider yourself fortunate with your family having the same interest as you.....Very cool...
tells me your spark plugs and pistons were hitting. tells me your oil not raceing oil. Tells me your well water not a good heat absorber. Many problems makes for good sleeperdude. We love you always.
I hope you're releasing more videos than this, this weekend!! It can't be just me that's been dying to see more of this movie! 4 days felt like waiting for the next season! (I know, unreasonable but still... ) Love the channel, love the family!!
@36:00 if you smear a really light coat of grease all over your paper gaskets they're a lot more likely to come off whole and be reusable, do it with all of my builds and never had sealing issues or anything from it. P.s. That looks to me like it's damage from both pre-ignition (pitted pistons) and detonation (melted plugs blown apart valves/piston) , probably brought on by being too lean on such a high compression build and/or possibly just not cold enough plugs.
Detonation usually leaves pitting and pre-ignition usually melts. My guess is maybe timing was on the edge, coupled with a lean condition increased the burn rate causing extreme cyl temps, a pressure spike and detonation. It's hard to say because there are symptoms of detonation and pre-ignition,.the lean condition could cause hot spots that pre-ignited.
Aluminum melts at 1,220 degrees. Snowmobiles operate at 1,100 degrees . Yah , you're always on the limit of destruction. I spent the extra money to put pyrometer gages on the exhaust . You can run larger jets to ad fuel . Fuel is part of you cooling of the motor. I didn't know that until i got into sledding. Love your videos. Keep knocking them out .
Dont quote me on that, but if I remember correctly they werent running a thermostat. If the water flow is too quick, then the water doesnt have enough time to take up the heat, so it can be counter productive, or so I've heard.
@@meszarosmate4629very true he did say he let it warm up for about 3 minutes and once he went flat out it probably heated up a lot def need a gauge for that heat next time lol
We’ll make sure you use gas , or in large the jets 3 times bigger than gas jets, lol thanks BigAl California for the next run thanks. Praise Jesus Christ grace amen 🙏
I think this may be a case where EFI would be the way to go, or drop the compression to 11:1 and go back to race gas. Methanol is great as long as you have a LOT of it. It definitely went lean up on the pipe, even if it was rich down on the idle circuit. I noticed it was spitting some out the pipes almost every time you started it, so maybe check your floats as well and see if one or both carbs are leaking. You really should have a return line off those carbs with a small orifice to keep pressure from building in the fuel system when it's warm and not running. That will also insure that the fuel coming into the carbs stays fairly cool. Even so, an ice-filled 'cold can' is a good idea to keep your methanol chilled as much as possible before it hits the carbs.😉
Always good to find out what went wrong...and realizing what was salvageable. For what you all accomplished to get it to the competition, outstanding! The next event will be awesome! Go get em Sleepercrew!
16:20 in, they call hypereutectic pistons, Swiss Cheese pistons for multiple reasons.. one being theres air pockets in the casting so if you cut one open they look like swiss cheese.. also they tend to melt/crack apart when pushed beyond what a stock commuter vehicle has to endure.
Well ... that;s unfortunate. You video's bring back so many memories. My dad was a local short track racer when I was about Ralphie's age. My job was to hold the flashlight ... still have nightmares all these years later. Best of luck getting the groceries back under the hood!
Thankfully the damage was not as bad as we all thought it was and I know with you guys will rebuild it stronger and better i am always sent back to my childhood watching your videos as kids we helped dad keep his cars going and like Josh he was always ready to answer our questions and show us how things worked now my brother and I keep his car in top shape looking forward to seeing the "Grem Ripper "chucking rubber and your family cheering you on God Bless Karl from eastern Canada
That's unfortunate! Pretty cool that you got help tearing the engine apart. For a minute I was thinking dorfman made the spark plugs. Thanks for the fun video!
Lost two engines with the same exact kinda damage, all be it was in an import under boost. But Ended up needing to have the geometry of the the combustion chamber changed to help scavenge the heat from combustion more efficiently. It would start to preignite and detonate under high rpm and boost from the heat building up. Ran inconel exhaust valves, stainless intake valves, and if memory serves 2 steps colder plugs. Put a thermocouple in each exhaust runner to monitor temps in real time. Both times bottom end was salvageable just needed a hone and pistons after being cleaned. Trashed the head though. Sorry to see it happen to y’all. Love the channel.
In my humble opinion, you had way too much timing in it. For it to burn it up that quick I absolutely love your show. Love your family. Keep up the good work old buddy.
You built this car and engine under a massive time constraint. A task that even professional car guys would have trouble with. You and your family can be nothing but proud that you even lasted that long without trouble. Who cares if you broke! You stole the show dude! I think you are incredible!! Been watching you for a few years now and have never commented, so yes, this is my first comment, so I thought you should know that you are amazing, and any other TH-camr that was there that watches your videos, and seen what you accomplished, know you are a force to be reckoned with in ever aspect of your skills and channel. Josh your family is AMAZING but you are the heart of the channel with what you know in the car game. Never lose hope or doubt yourself bro. Love you guys! Full confidence this will be ready for the next event in 2 weeks since it is just engine and not full car build lol BTW WaWa, that torque converter is a shade of purple not blue lol lol... and Josh run the forged pistons this time plz
Sorry the engine got hurt but you sure put on a good show, saw you on a couple of other people's reels, your getting popular. Thank you for taking us along on the tear down. Looking forward to learning with you on what happened. 👍
This little Gremlin made a great little burnout car unfortunately you fed it after midnight and the gremlins were unleashed. Hopefully you can get everything you need ordered and in before the next event. You gave it the beans and put on a great show for the fans in the stands I was thinking that it needed eye's to get the CARS look and seen one shot there they were in True to the look you were able to nail it. Great job to the family on getting this together and making it all happen. It was a lot of work and great content seeing you all working to get to Bristol she sounded like a beast and that really was a spicy tip in as always keep up the good work and great content. It definitely was lucky it stayed together and it wasn't a total loss . As always keep up the great work and sorry to hear that George Nelson made a wonderful from your envelope!
I think it could have been a machining problem. Heat may have done some damage but what caused it? Did you have the engine balanced? The smallest vibration get amplified when you step on it and can tear an engine apart in a short period of time. Heat would begin to build up causing more damage.
I would install an AIR TO FUEL RATIO sensor with gauge and danger zone light. Is there a way you could electronically reduce the engine revolutions if the engine fuel system senses a about to go lean condition? Or a way to enrich the fuel ratio-supply at the highest engine revs? I think that would protect the engine. Maybe convert to a single carburetor? Anyway good on you to inspect what went wrong and learn from it. You and your family will be the next Edelbrocks. Keep tuning and keep racing! Well done Sleeperdude and family and Rocky!!
Keep an eye out for a 1967 dodge 318 engine. They came from the factory with a forged steel crankshaft. Bore it to 4" and use 1969 340 pistons and rods. Have it balance and build it from there. Run it on high test gas and you will have an excellent burnout engine at a reasonable price.
More Kitties on video Please! Was at a shop the other day they had Two kitties. One little one and BIG one. The big one liked me A lot! Wanted to take him with me on the truck I drive. But, ..You know.
Ok, few things here, mount your gauges where you can see them, run a t-stat of about 180, put temp sensors on the exhaust pipes, switch to marine style spark plugs and open the jets. Quick way to know if the fuel mix is good is if the exhaust makes your eyes sting like you have soap in them. Ask some circle track racers what they do to set up their engines.
And when exactly are you going to jet the carb and tune the car when you're doing a burnout in front of 10k people? 🤣You tune and set up the car using the Wideband BEFORE the event. It's really not that hard to understand. After which, it will alert you if you go lean for whatever reason, during the burnout, if mounted in a location that is anywhere near your peripheral vision. @@Carl_Jr
You also need to check your fuel system. You need about 3 times as much methanol as gas. Your fuel pump and line size need to be able to handle that. You may need to run a little higher fuel pressure as well
I think his fuel system is more than capable of supplying enough, but I think he has it set on 1/2 or 3/4. Maybe he needs to put the pump on the highest setting who knows
Melted pistons I agree it has to be a lean issue with the methanol. I had a friend who used aircraft fuel and for a 5 gallon jug he used type F transmission fluid for lubrication purposes he would add fluid till the fuel turned colors. I don’t know if this would help you in this situation but I would think u needed more lubricant in your fuel and richen your fuel mixture. To be on the safe side I’d recommend forged pistons.
@@bradpaynter6719 - I think so too! I thought that you had done that already - Balance the entire reciprocating assembly(including pistons, rods, caps and the crank) is the easiest racing trick for an engine re-builder to do by themself(except crankshafts) and is probably the reason your piston damage is spread out unevenly. If you try to pinpoint diagnose any ONE problem that blew up Gremmy, you may be in for a lot of frustration; but if you balance ALL the parts of your reciprocating mass to within a tenth of a gram(it's been 40 years since I balanced my 340 'Cuda engine; you might be able to match them closer), you should have LOTS less engines blown up. I never discovered my top end - my 'cuda would go to the "P" in MPH on the speedometer - and I NEVER blew it up. That's what all those straight sections are on those parts; the smooth areas that look like bars or blocks. They are extra material, DESIGNED for you to grind away, to balance the weight of all of the reciprocating items. Remember the lyrics for "Little Deuce Coupe," by the Beach Boys - where it said, "She's balanced and relieved, and she's stroked and bored, she'll do a hundred forty in the top end, floored?" The FIRST word of description of the "magic Hot-Rod Tricks" is Balanced.
Dave Smith, not my engine build, however, I concur with your statements regarding balancing. I do my own rods, pistons, etc. When I balance parts I get them down to less than a tenth of a gram for the full set of pistons and rods. My goal is to always have the entire assembly below 1 gram total out. Takes longer but there are the rewards of a very smooth running engine. The pistons in this case should be forged! I’d also go with coated bearings for protection at sustained high rpm’s. I too once had a 340 4spd Dart GTS, we’ll built! They’re great engines!
You can see how sad Josh is, loosing that much in parts hurts, but hopefully this video continues to get views. Just ask that TH-camr that tears down wrecked engines on TH-cam, idocars. People love to see that carnage! And especially seeing the kids reactions is really good content! Also, I recommend a tshirt with WaWa captioned with “that’s crazy”
Make sure you have both the same size tyres on the back next time you can’t have different tyres with a locked diff or it will jump all over the place 😂 and try soaking some diesel on them makes it smoke to hell ❤
Dear kellylucas. 👍👌👏 Yes, you are absolutely right. Additionally: Trailer rims don't sit centered enough on the brake drums. Because usually the hole in the trailer rim is bigger than the hub. At least that's the way it is in Germany. And from the looks of it, it's similar in North America. 2) Sleeperdude mentioned a lot of vibrations while doing the burnout. This definitely helped to destroy the engine. Therefore the DIY drive shaft must be checked and balanced. So should the crankshaft! Best regards, luck and health in particular
From Australia burnout kings of the world can’t wait for Summernats ps America farm truck was a joke better luck next time at least sleeperdude can do the dip in 👍🏻
At a RC event this weeked! Got tv hooked up outside the camper 65” watching your new video with about 25 people!!! Love the videos man!!! Keep up the good work
I'm literally building a 74 360 at the moment! Not as hard as your guys but damn son! lol You put some yeet through that motor. Love it! Great job and that gal sounded proper when she was on it. Love it!
Well, it's good and bad. A lot of parts to include the block are re-usable. I would replace all the crankshaft, rod, and camshaft bearing though. Great inspection and tear-down. The kids did learn a lot.

Like he said… …..I have no knowledge of Methanol, outside of what I learned on Breaking bad. I’m kind of surprised you didn’t go turbo.
Bad parenting: those kids don’t know their colours! That’s purple.

MAN ! You guys have an awesome thing going on there. With a family like that there is no losing ; just winning at different levels. You are blessed . Your videos always make my day.
Josh, you need to put a Nader style shutoff valve under the hood. You need to shut the valve off and run the motor out of fuel. Racing alcohol will go past the rings. I used to run circle track cars and the fuel gets milky really easy.
Also you have to run at least -8 fuel line. If you are running 3/8 line, you are not feeding enough fuel. You burn twice as much fuel than gasoline. I used to run a single 750 carb on a 13:1 406 sbc and I believe I had like .140 jets.
I don’t personally know but I’ve read that methanol runs lean and the best way to tell if you have the right mixture is with an oxygen sensor to read the exhaust gases.
My personal prognosis is it went lean on one carb, probably due to the bowls running dry (looks like it was the rear one). Maybe you should go to a swirlpot design with two holley blues sucking off that and a separate reg for each carb with a return system rather than a deadhead setup..
You need to remove all the bearing including the cam bearings and have that block cleaned out for there is now metal particles in every part of that engine. and mic the crank have it polished. This is why I never ran alcohol in my engines. buy good racing fuel. I wish you the best on the rebuild of this engine.

You're thinking of you're making it back out, we sure are anxious for you to! Good Luck!
Dang it all my Pringles are broken too!!!
Well, at least it did not break at the track. Inside the garage was unreal. Can’t wait for the Bristol Event. Know you will get it. Ralphie,Wawa, and mom keep you going. Thanks for sharing!
💯👍👊
That’s true thank you
You are up there with Craig 909 now 😆. My guess would be something happened with the fuel. Lean. The big sad Josh. I told you 401 AMC 😆
And be darned sure the amount of initial and centrifugal advance is appropriate for the methanol. Glad the engine was not hurt worse. And you did good at the competition!
That's very unfortunate for poor Grem but you guys will get him up and running again. We really appreciate all the time and effort you guys put into these projects and videos they never disappoint.
Don't be discouraged....you will recover from this....best wishes for your success!!
Thank you
Might build her little more in the loose side this time. Think they tighten up running like that for that long. That tunnel Ram is a barrel for every cylinder. Might do some individual tuning, depending the top. 🤔 might run it 15, then 30 , and work your way up and tune as you go. You’ve burned the cadmium off all of them, looks like lean, and like you said, your going for so long, just keeps getting hotter. Think you did pretty awesome considering the time frame lol. She got put right together and was gone smoking tires, right quick! You’ll get her figured!
Josh, My family has a background in truck and tractor pulling. We run methanol in our puller. My Dad and I watched your breakdown video together and had a few ideas for you. For a methanol setup expect to run twice as much fuel compared to gasoline. Gasoline is 14 to 1 air fuel ratio and methanol is 7 to 1. We'd recommend using forged pistons and maybe inconel exhaust valves. The 360 the heads are limited , consider a 440 if possible. Also methanol always gets in the oil, get used to changing the oil after every event this is normal. Consider cutting about 12" to 15" off of the headers, that should bring up the R's.
This is so incredible how both kids and Josh know what to take apart to see what's in pieces? And they are very interested in what's wrong with it? Love this show for that!!
Teaching America to stay humble and never quit. Y’all never get cranky and are always supportive. Love this channel!
Brother you got the best family their behind you through this...... You guys working on all this after that blew up all I see is love
If I had to guess I'd say your fuel system couldn't keep up. When I heard it die my first thought was running lean and melted pistons. That's definitely all the signs of detonation from specks on the plugs to beat up top half of the rod bearings.
Yup.
The torque converter 🍩 could go down in the history as another one of the great color controversies of all time along with “the dress” from a few years ago. At first i’d of said it’s purple but after doing some research outta boredom it’s a tough call because there’s pictures where it definitely looks purple as well as picture where it definitely looks blue. 🙃 Oh well you still did a great job, the car did awesome up until it didn’t. To do all that in a the short amount of time was amazing so I have complete faith you’ll get it back together. You all are awesome!
Conveter was in Led's shadow initially, then moved out into Led light. So that's at least 3 different variations in colour temperature! Plus angles, individuals eyes. A whole basket of variables - weirdly!!!!!!
The paint is blue. All B&M converters are painted blue. However, that doesn't mean it stayed blue. LoL
The donut is purple
Burple.
Love watching y'all work together!
With 13.5 compression ratio and a lean mixture, it should have blown sky high.
A hemi may tolerate that a little longer,a but never a wedge.
You may want to try 10.5 to one next time, richen it up, and please have the engine finally balanced.
Running wide open with an unbalanced engine is a formula for chaos!
Still very much enjoy your homespun videos, and kids always pitching in.
You're an awesome Mom/ dad combination.
Thank you
Spot on. 13.5 compression is very high. You can go with less and still compete. Keep the motor alive for another day….
Yeah this was what I think it was. The vibrations from the unbalanced assembly at high speed would have been sending shockwaves through the engine when running over 5k. Something was going to fail. And if a carb was lean, a little heat, with some extra vibration that causes more heat... That machine shop, couldn’t get around to balancing a crank, boy they deserve a special place….
I did failure analysis on components for the space shuttle for more than 30 years. Failure analysis is one of the most challenging and interesting things you can do. You can’t help but feel like Sherlock Holmes when your working a difficult one. Love the looks on your and the kids faces as you discovered each “fact”. Looks like you might have two future metallurgists on your hands.
Wow that is interesting. My dad is a quality engineer
My guess on the insert bearing wear patterns- The crank was whipping lightly. That is lack of balance. I agree on the detonation guess.
Ok thanks
@@Sleeperdude You and your family are very blessed! Carry on!
The oil sprayed everywhere was what I was talking about that you need catch cans for the breathers so it won't as you're spinning around/at high rpm. When methanol goes lean it will burn hot.. Again, I said it in a previous comment, that's down to the floats being that angle when you're spinning around.. one side is getting flooded while the other side of the carb/engine goes lean. Not having had that engine on the dyno or having EGT sensors in each runner is part of what killed it.. You have no clue where the fuel is going. If you watch Engine Masters they often have to have a different jet at each corner of each carb with tunnel rams because they distribute fuel in weird ways. EFI really is SOOOO much better when messing with methanol or nitromethane. You need to be able to tune each cylinder separately and know exactly what's going into each hole. The valve cracking could've just been down to a manufacturing defect.
A piece of advice, when you have a blown up engine, don't turn it over on the stand.. take the pan off the way it sits, when you flip it over you're just dumping any pieces of metal into the engine.
Your biggest problem is the simplest to fix.. you don't have a shelf full of broken parts.. You HAVE to have a shrine for Tributes to the Gods of Speed. Learn from Burt Munro. (if you haven't ever watched World's Fastest Indian you're missing out.)
Been waiting on this one to see what happened... Keep up the good work Sleeperdude!!
Thank you for watching
Yep, you're welcome
Keep up the family working together awesome to see any time sent together as a family is valuable
Amazing how much of the engine is still good. Love the show.
Glad you enjoy it!
@@Sleeperdude yes and thanks for the tip on the USS Cairo. I just completed a month long road trip and filmed the Cairo (acknowledgement to you on the episode). Love that history 👍
Hi there.I am Curtis from Powell River, BC. I love your shows. I watch every day.
Love this Gremlin series Josh!
It's more interesting to see what can go wrong sometimes than to have everything go perfect!
This is entertaining like that scene in Apollo 13 when they fly by the service module and see the damage and also all the problem solving they did!
Two thumbs up!
Sleeperdude family
THX GUY'S ,GREAT TO SEE THE DAMAGES DONE ,,AND LOOK FORWARD TO THE REBUILD ! REALLY ENJOYED THE VID !
Josh I had a friend used the same pistons you used in a neon and within 1000 miles they shattered and messed up the block his next build had stock pistons and it’s been 3 years now and still running it
Mr. Sleeperdude, your videos are addicting to watch and reminds me so much growing up with my dad and his cars.....Consider yourself fortunate with your family having the same interest as you.....Very cool...
You can use Muriatic Acid to take the aluminum off the sleeve .🤩 Great video
Thanks for the tip. I have used it before on a bore to get rust out of pits. It was nice talking to you at Bristol.
tells me your spark plugs and pistons were hitting. tells me your oil not raceing oil. Tells me your well water not a good heat absorber. Many problems makes for good sleeperdude. We love you always.
I hope you're releasing more videos than this, this weekend!! It can't be just me that's been dying to see more of this movie! 4 days felt like waiting for the next season! (I know, unreasonable but still... ) Love the channel, love the family!!
I think you will have her ready in time for the Mopar, My God bless you all and make it happen ❤
@36:00 if you smear a really light coat of grease all over your paper gaskets they're a lot more likely to come off whole and be reusable, do it with all of my builds and never had sealing issues or anything from it.
P.s. That looks to me like it's damage from both pre-ignition (pitted pistons) and detonation (melted plugs blown apart valves/piston) , probably brought on by being too lean on such a high compression build and/or possibly just not cold enough plugs.
Detonation usually leaves pitting and pre-ignition usually melts. My guess is maybe timing was on the edge, coupled with a lean condition increased the burn rate causing extreme cyl temps, a pressure spike and detonation. It's hard to say because there are symptoms of detonation and pre-ignition,.the lean condition could cause hot spots that pre-ignited.
Aluminum melts at 1,220 degrees. Snowmobiles operate at 1,100 degrees . Yah , you're always on the limit of destruction. I spent the extra money to put pyrometer gages on the exhaust . You can run larger jets to ad fuel . Fuel is part of you cooling of the motor. I didn't know that until i got into sledding. Love your videos. Keep knocking them out .
Hey josh, did you jet the carburetor to run methanol? Methanol runs lean, not jetting for it can cause catastrophic engine damagea
Good point!
Dont quote me on that, but if I remember correctly they werent running a thermostat. If the water flow is too quick, then the water doesnt have enough time to take up the heat, so it can be counter productive, or so I've heard.
@@meszarosmate4629very true he did say he let it warm up for about 3 minutes and once he went flat out it probably heated up a lot def need a gauge for that heat next time lol
@@meszarosmate4629 I follow.
We’ll make sure you use gas , or in large the jets 3 times bigger than gas jets, lol thanks BigAl California for the next run thanks. Praise Jesus Christ grace amen 🙏
You need to check out Thunder 289. And check the product that he has for carbs and see if you could use it for dual carb setup
I think this may be a case where EFI would be the way to go, or drop the compression to 11:1 and go back to race gas. Methanol is great as long as you have a LOT of it. It definitely went lean up on the pipe, even if it was rich down on the idle circuit. I noticed it was spitting some out the pipes almost every time you started it, so maybe check your floats as well and see if one or both carbs are leaking. You really should have a return line off those carbs with a small orifice to keep pressure from building in the fuel system when it's warm and not running. That will also insure that the fuel coming into the carbs stays fairly cool. Even so, an ice-filled 'cold can' is a good idea to keep your methanol chilled as much as possible before it hits the carbs.😉
Hi y'all I'm a Mopar guy I pray the engine can be saved
Always good to find out what went wrong...and realizing what was salvageable.
For what you all accomplished to get it to the competition, outstanding!
The next event will be awesome! Go get em Sleepercrew!
I’ve burnt holes in pistons on NA gasoline engines. And it was because of too much advanced timing at wide open throttle.
I honestly thought it would be worse than the Malibu. Now you can build up even better
🤣🤣🤣
I love your TH-cam show I love to watch you and your kids work together God bless you😊
16:20 in, they call hypereutectic pistons, Swiss Cheese pistons for multiple reasons.. one being theres air pockets in the casting so if you cut one open they look like swiss cheese.. also they tend to melt/crack apart when pushed beyond what a stock commuter vehicle has to endure.
Hmmm good to know
Well ... that;s unfortunate. You video's bring back so many memories. My dad was a local short track racer when I was about Ralphie's age. My job was to hold the flashlight ... still have nightmares all these years later. Best of luck getting the groceries back under the hood!
Sorry for your luck guys. Look forward to the rebuild. What a wonderful bunch you guys are. 👍👍🇨🇦
personally and selfishly i'm glad it blew up, becouse i like these "what went wrong" teardown videos 😄
No worries you can get the engine fixed. I have complete faith in you. I will say you have the patience of a saint. ❤
Thank you
You see on the faces of the kids the really enjoying in what they are doing. 😊
No matter what the situation was, it was still awesome to see doing your best....
Thank you
Thankfully the damage was not as bad as we all thought it was and I know with you guys will rebuild it stronger and better i am always sent back to my childhood watching your videos as kids we helped dad keep his cars going and like Josh he was always ready to answer our questions and show us how things worked now my brother and I keep his car in top shape looking forward to seeing the "Grem Ripper "chucking rubber and your family cheering you on God Bless Karl from eastern Canada
Here’s hoping that you get it all sorted out before the next event. Stay safe Sleeper family.
That's unfortunate! Pretty cool that you got help tearing the engine apart. For a minute I was thinking dorfman made the spark plugs. Thanks for the fun video!
Lost two engines with the same exact kinda damage, all be it was in an import under boost. But
Ended up needing to have the geometry of the the combustion chamber changed to help scavenge the heat from combustion more efficiently. It would start to preignite and detonate under high rpm and boost from the heat building up. Ran inconel exhaust valves, stainless intake valves, and if memory serves 2 steps colder plugs. Put a thermocouple in each exhaust runner to monitor temps in real time. Both times bottom end was salvageable just needed a hone and pistons after being cleaned. Trashed the head though. Sorry to see it happen to y’all. Love the channel.
This. Colder plugs and MORE FUEL.
Great teardown and Big smiles,
Much love to all 🥰 Aj
In my humble opinion, you had way too much timing in it. For it to burn it up that quick I absolutely love your show. Love your family. Keep up the good work old buddy.
Yeah maybe so
You built this car and engine under a massive time constraint. A task that even professional car guys would have trouble with. You and your family can be nothing but proud that you even lasted that long without trouble. Who cares if you broke! You stole the show dude! I think you are incredible!! Been watching you for a few years now and have never commented, so yes, this is my first comment, so I thought you should know that you are amazing, and any other TH-camr that was there that watches your videos, and seen what you accomplished, know you are a force to be reckoned with in ever aspect of your skills and channel. Josh your family is AMAZING but you are the heart of the channel with what you know in the car game. Never lose hope or doubt yourself bro. Love you guys! Full confidence this will be ready for the next event in 2 weeks since it is just engine and not full car build lol
BTW WaWa, that torque converter is a shade of purple not blue lol lol... and Josh run the forged pistons this time plz
Sorry the engine got hurt but you sure put on a good show, saw you on a couple of other people's reels, your getting popular. Thank you for taking us along on the tear down. Looking forward to learning with you on what happened. 👍
Forged pistons a must! Carb jetting 2nd. Special oil for methanol..
Like the videos! Keep smiling 😃!!!!
The moment we've all been waiting for 😬
Scary stuff
This little Gremlin made a great little burnout car unfortunately you fed it after midnight and the gremlins were unleashed. Hopefully you can get everything you need ordered and in before the next event. You gave it the beans and put on a great show for the fans in the stands I was thinking that it needed eye's to get the CARS look and seen one shot there they were in True to the look you were able to nail it. Great job to the family on getting this together and making it all happen. It was a lot of work and great content seeing you all working to get to Bristol she sounded like a beast and that really was a spicy tip in as always keep up the good work and great content. It definitely was lucky it stayed together and it wasn't a total loss . As always keep up the great work and sorry to hear that George Nelson made a wonderful from your envelope!
You might want to have your engine shop mic the crank or do it yourself to make sure it is round on each crank pin(For the rods).
Ok thanks
for those of us who have no idea what that meant th-cam.com/video/UfMGVODuVAA/w-d-xo.html @@Sleeperdude
I think it could have been a machining problem. Heat may have done some damage but what caused it? Did you have the engine balanced? The smallest vibration get amplified when you step on it and can tear an engine apart in a short period of time. Heat would begin to build up causing more damage.
Don't be mean sleeperdude. @@Sleeperdude
Sorry for the motor. But is so Nice to see u guys working together... Love from Norway
Channel keep it going loved watching y'all at Cletus event it was cool you put on a hell of a show thank you
Thank you we appreciate it
I would install an AIR TO FUEL RATIO sensor with gauge and danger zone light. Is there a way you could electronically reduce the engine revolutions if the engine fuel system senses a about to go lean condition? Or a way to enrich the fuel ratio-supply at the highest engine revs? I think that would protect the engine. Maybe convert to a single carburetor? Anyway good on you to inspect what went wrong and learn from it. You and your family will be the next Edelbrocks. Keep tuning and keep racing! Well done Sleeperdude and family and Rocky!!
Keep an eye out for a 1967 dodge 318 engine. They came from the factory with a forged steel crankshaft. Bore it to 4" and use 1969 340 pistons and rods. Have it balance and build it from there. Run it on high test gas and you will have an excellent burnout engine at a reasonable price.
More Kitties on video Please! Was at a shop the other day they had Two kitties. One little one and BIG one. The big one liked me A lot! Wanted to take him with me on the truck I drive. But, ..You know.
Ok, few things here, mount your gauges where you can see them, run a t-stat of about 180, put temp sensors on the exhaust pipes, switch to marine style spark plugs and open the jets. Quick way to know if the fuel mix is good is if the exhaust makes your eyes sting like you have soap in them. Ask some circle track racers what they do to set up their engines.
Really? It's a burnout car. LoL
Talk about putting lipstick on a pig. 😂
Wideband to monitor AFRs is a must. Better to put lipstick on a pig than blowing holes in pistons at every outing. @@Carl_Jr
@@danielblizzard701 and when exactly are you going to be able to watch the afr gauge when you're doing a burnout in front of 10k ppl?
LoL 🤣
And when exactly are you going to jet the carb and tune the car when you're doing a burnout in front of 10k people? 🤣You tune and set up the car using the Wideband BEFORE the event. It's really not that hard to understand. After which, it will alert you if you go lean for whatever reason, during the burnout, if mounted in a location that is anywhere near your peripheral vision. @@Carl_Jr
@@danielblizzard701 So that way you can stop to "save the engine" and ruin the fucking show for everyone! Hell yeah, brotha! 🙄
I love yalls videos especially when all of yall are spending time in the shop working on your cars
We need a Shirley counter
True
Don't forget to check the engine oil pump. If its picked up any metal bits they could have scored the gears.
Ok thanks
❤keep at it ❤❤❤❤God bless you all 🙏
Get a wide band o2 setup and monitor your fuel ratio. Maybe a egt guage too?
You also need to check your fuel system. You need about 3 times as much methanol as gas. Your fuel pump and line size need to be able to handle that. You may need to run a little higher fuel pressure as well
I think his fuel system is more than capable of supplying enough, but I think he has it set on 1/2 or 3/4. Maybe he needs to put the pump on the highest setting who knows
@@rusticrebuilds how would you know the fuel system will flow enough?
Melted pistons I agree it has to be a lean issue with the methanol.
I had a friend who used aircraft fuel and for a 5 gallon jug he used type F transmission fluid for lubrication purposes he would add fluid till the fuel turned colors. I don’t know if this would help you in this situation but I would think u needed more lubricant in your fuel and richen your fuel mixture.
To be on the safe side I’d recommend forged pistons.
I would go with forged lower compression pistons coated for high temperature.
Alcohol needs really high compression to be used.
Forged Yes, lower compression absolutely not.
Balance the rotating assembly!
@@bradpaynter6719 - I think so too! I thought that you had done that already - Balance the entire reciprocating assembly(including pistons, rods, caps and the crank) is the easiest racing trick for an engine re-builder to do by themself(except crankshafts) and is probably the reason your piston damage is spread out unevenly. If you try to pinpoint diagnose any ONE problem that blew up Gremmy, you may be in for a lot of frustration; but if you balance ALL the parts of your reciprocating mass to within a tenth of a gram(it's been 40 years since I balanced my 340 'Cuda engine; you might be able to match them closer), you should have LOTS less engines blown up. I never discovered my top end - my 'cuda would go to the "P" in MPH on the speedometer - and I NEVER blew it up.
That's what all those straight sections are on those parts; the smooth areas that look like bars or blocks. They are extra material, DESIGNED for you to grind away, to balance the weight of all of the reciprocating items. Remember the lyrics for "Little Deuce Coupe," by the Beach Boys - where it said, "She's balanced and relieved, and she's stroked and bored, she'll do a hundred forty in the top end, floored?" The FIRST word of description of the "magic Hot-Rod Tricks" is Balanced.
Dave Smith, not my engine build, however, I concur with your statements regarding balancing. I do my own rods, pistons, etc. When I balance parts I get them down to less than a tenth of a gram for the full set of pistons and rods. My goal is to always have the entire assembly below 1 gram total out. Takes longer but there are the rewards of a very smooth running engine. The pistons in this case should be forged! I’d also go with coated bearings for protection at sustained high rpm’s. I too once had a 340 4spd Dart GTS, we’ll built! They’re great engines!
Thank you for showing us what happened to the engine. Way to go Josh real good video .
You guys work together so good thanks for letting me watch 😂
You can see how sad Josh is, loosing that much in parts hurts, but hopefully this video continues to get views. Just ask that TH-camr that tears down wrecked engines on TH-cam, idocars. People love to see that carnage! And especially seeing the kids reactions is really good content! Also, I recommend a tshirt with WaWa captioned with “that’s crazy”
Make sure you have both the same size tyres on the back next time you can’t have different tyres with a locked diff or it will jump all over the place 😂 and try soaking some diesel on them makes it smoke to hell ❤
Dear kellylucas.
👍👌👏 Yes, you are absolutely right. Additionally: Trailer rims don't sit centered enough on the brake drums. Because usually the hole in the trailer rim is bigger than the hub. At least that's the way it is in Germany. And from the looks of it, it's similar in North America.
2) Sleeperdude mentioned a lot of vibrations while doing the burnout. This definitely helped to destroy the engine. Therefore the DIY drive shaft must be checked and balanced. So should the crankshaft!
Best regards, luck and health in particular
From Australia burnout kings of the world can’t wait for Summernats ps America farm truck was a joke better luck next time at least sleeperdude can do the dip in 👍🏻
At a RC event this weeked! Got tv hooked up outside the camper 65” watching your new video with about 25 people!!! Love the videos man!!! Keep up the good work
I'm literally building a 74 360 at the moment! Not as hard as your guys but damn son! lol You put some yeet through that motor. Love it! Great job and that gal sounded proper when she was on it. Love it!
Yes!!!!
Well, it's good and bad. A lot of parts to include the block are re-usable. I would replace all the crankshaft, rod, and camshaft bearing though. Great inspection and tear-down. The kids did learn a lot.
