Thank you Eric's mom and dad. First for making him and raising him to be a fine upstanding citizen and for going to pickup the Viper engine for this week's video.
On the 5th day of Christmas "I Do Cars" sent to me....5 spun bear- rings 4 stickey carbs 3 bent rods 2 cracked blocks ...and a VIPER with a Tree Leaf !!!!!!
Piston Nuggets and Special Sauce! As a retired mechanical engineer, I truly enjoy the diagnosis, failure analysis and possible root cause failure points. I enjoy your running commentary on disassembly procedure. You are fun to listen to and a great instructor. I have learned much from your videos. This channel rocks!
It would be interesting to clean up the internal debris and arrange it in as-close-to original positions as possible, as they do with some crashed-airplane reconstructions. He did some of it with the exploded rod, but I would like to have seen the pieces of the piston laid out too. A bit of a jigsaw puzzle. -- Also, I think in tear downs like this, it would be good to have a little slab made of 2x4s, to slip onto the base of the engine stand for the moments of last-bolt removal, when a part is likely to fall onto the base or the floor. Just something to soften the initial impact. A couple of short 2x4s could also have supported the intake manifold when he was trying to sort out the last electrical connections.
What we really need is an engine with all kinds of carnage that comes complete with video of either the noise it was making before, or the noises it made *when* she blew.
I'd love to see a teardown of that runaway diesel that's been going around on YT/social media, the one from some car show where you can see the block literally glowing from the wheel wells. found it - this one ua-cam.com/users/shorts5CBKDP6BqYU
Locking tabs on electrical connectors are hardly just a Chrysler phenomenon, and I personally don’t understand the hate for those specific connectors considering how easily they come apart relative to other types of locking connectors.
Agreed. Cummins uses them too on some of their engines. I deal with a lot of B/ISB/QSB6.7 engines, and they're always on the EGR and valve cover, and a few other things. They really suck.
I drive a 2010 Pt and usually I just unscrew or remove whichever sensor rather than messing with those locking clips, trying to undo those things is like trying to separate two pieces of tissue paper that are superglued together without ripping either one
Years ago when I was a tech for Mercedes Benz in my hometown, a customer from a Dodge dealership came to us and asked us to tear down the engine in his viper and rebuild it for him, and he wasn't interested in how much it would cost him, so we did it. there was a considerable amount of damage in the engine, mainly the crankshaft bearings, we did some tests and found out that the engine had well over the .030" clearance that would keep the engine safe from problems of excessive clearance. the engine had less than 20,000 miles and it is likely that the engine had been built from Factory with the Maximum allowable clearance, so that the engine would be putting out lots of power, unhindered by tolerance that were too close. I knew that this was a tactic that many race crews used to make their engine perform well on the track, but those engines were always rebuilt after each race. But this is what Dodge did with factory engines! and the limit on the Viper power train warranty was 25,000 miles! they knew the engines wouldn't last and tried to cover their arses, and although this guy's viper was still under warranty, they accused him of excessive abuse of the engine and refused to honor the warranty, but this guy wasn't gonna have it. he told us to make every change necessary and not to spare any cost nor should we try and make any deals for him, he said he was going to sue Dodge for the repairs and make them pay for the bill. So we made that viper engine tight and within spec of .010" clearance on the mains and the various clearances of the standard 340 v-8 and the viper v-10 is just a copy of the 340 with two extra cylinders added to the rear of the block. we put it back together so well, in fact that the guy came back years later and said he had never had as reliable an engine from Dodge in his life, he had well over 115,000 miles of the engine and it was still going strong. it wasn't as powerful as it was before but he said that it was alright anyways because he had a good engine. He sued Dodge, and won, and the tab was picked up by Dodge, and that was during the years when Dodge/Chrysler was being dragged into court kicking and screaming for not honoring their warranties like they were bound to by law. one of the many reason why Dodge Chrysler was sold to FIAT to stop them from gong Bankrupt again! My advice to anyone is to stay away from Chrysler products entirely, the company has had so many times been such a poorly operated and terrible customer service driven corporation that it just doesn't make any sense to trust them. I could fill you with stories I have come across as an auto tech about Chrysler and how they operate that I would NEVER buy any Chrysler product, ever. The biggest problem is that they make nice looking vehicles, and that lures far too many people in to buy their junk. Hopefully Fist can turn them around but if Mercedes Benz couldn't do it when they owned them, I doubt Fiat can do it either.
Only issue I've had is with the hemi, and the common lifter issue but I don't mind doing the work myself which I have. I'll always stick with their products. I run my stuff hard and I love the 5.7. Hearing all these stories though about the viper engine, no thanks
Sounds to me like the inginerds did their part, but then management got involved to help uhh... "fix" things. For the marketing department, you see! Because middle managers with MBAs _always_ know better...
@@mojoblues66 I wouldn't be surprised if it's as much as 10% or more. Parasitic loads are a huge thing in engines. That's basically where all your engine braking comes from. That and a little bit of entropy in the compression cycle, but that's negligible compared to the parasitic loads. I'm sure you've heard about thermal efficiency of combusion engines, and that the Otto cycle is 15% while the Diesel cycle is about 45%. That's foe the thermal cycle only though. In other words, it's all the energy you could ever possibly get out of the fuel you put in. Then come the parasitic loads. Oil pump, water pump, valve springs, HP fuel pump (if present), all the friction from the sliding contact inside the cylinders, plus all the auxiliaries - alternator, AC compressor, power steering pump... hell, even the bearing grease inside the idler pulley's bearing. These things all add up to sap a bunch more power out of your engine. Then there's a 10% loss from the drivetrain components on top of that (assuming a manual gearbox, more if it's a slushbox)... By the time you get to the wheels, you're looking at closer to 10% from the Otto cycle, 30% from the Diesel cycle. If you can do something about those parasitic loads (such as loosening up all the bearings), you'll get some measurable benefit. Probably even measurable by your average arse dyno.
Piston nuggets, bearing foil, and multi-cylinder connecting rods! Eight cylinders seem pretty good looking; maybe someone will want a Viper V-8?? Honestly, I'm impressed this engine didn't completely grenade with tennis ball size exit holes in the block. Thank you for sharing; it was interesting to see how this engine is assembled.
@@colchronic i've known about v8s that ran with 2 cylinders having 0 compression for some time so it's not unlikely it could be still running but it's definitely not going to be running good Edit: upon completion of watching the video i have revised my opinion on this engine... it definitely did not run
In my tenure in the shop I rebuilt close to 400 engines and I’ve never seen that much carnage in an engine. Merry Christmas to you and yours Chris! Tell your parents thank you for bringing this Christmas present to your shop!
If you think this much carnage was bad, head over to the Steve Morris channel and check out his video on his 4k HP engine where all 8 rods exploded at the same instant.
I was part of a 5.0l engine tear down at CEP#1 in the early 90's. Our plant required that any engine deemed defective had to come back for tear down before a new engine was released. This engine was a 5.0l Mustang, which was ironically owned by a Ford employee. When the intake manifold was removed we found the foil seal off of the oil container lying in the tappet valley. Enough said, I'm pretty sure the leaf you found was the cause of this V10 blowing up. Great videos keep them coming.
Merry Christmas Eric. I'm not a mechanic or a car guy but I'm glad I found your channel. Love your content and you have made me think about how I'm taking care of my car.
As a retired engineer I love watching these videos! I've loved cars and racing them for the past 20 years and getting to see the internals of a bunch of different engines really tells me a lot about the engineering that went into them. You can just about see the philosophy that went into the design. With the Viper we have an old school V8 that they want more power out of but have hit the limit of the block design, so let's just add two cylinders. But let's keep it old school simple: single cam with pushrods, no oil squirters up the bore to cool the pistons which would complicate the block casting. Just a 25% longer block and cam. What could be easier? Thanks, Eric, really enjoy these videos!
I watched a documentary on Ford's Formula 1 engine development from just a few years earlier than the Viper was conceived, and it makes sense to me now why companies used to do silly stuff like this (or what seemed silly to me). Cosworth tried using an existing factory Ford engine block to develop the race engine out of but the webbing turned out to be too weak and the crank would distort at high RPM. They had to go with a clean sheet design and the movie went through the whole engine development process of a new V6. It was so expensive to CNC machine a casting mold in that era that they still opted to have people hand carve them out of Brazilian mahogany. Needless to say it was insanely expensive to go through this process, not to mention all of the tooling they would inevitably have to adapt the design to in order to mass produce any new engine on the same assembly lines as other ones in the fleet. Slapping an extra pair of cylinders on the end of a truck V8 starts to make sense now. Same with the 90 degree V6's that were based on V8 engines. I still think as a long term strategy it hurt all of the domestic OEMs to design engines this way, but at least you can see their line of thinking. They were concerned with quarterly and annual reports, the short term profitability that effected their images and bonus pay in the short term.
@@randr10 Reminds of a Henry Ford story , all his bean counters came to his office and Mr.Ford you are losing thousands and thousands of dollars, on this farming stuff and if you keep doing this you will go broke Mr.Ford . He was looking out of his office window turned around and said , that is the best news i have heard all year ....
@@randr10 Oh on the farm stuff . Ford was a farm boy growing up and he hated how the farmers had to work , and he was gone help all farmers come hell or high water.So point out some one like him today ...impossible ...........................
I was a technician for 17 years before I bought a Snap On Tool business. I have seen some really bad engine detonations but by far this Viper V10 engine was just mind boggling with hundreds of questions. I only wish I could have heard it explode. Rainman sent me to your sight and by far you do such a great job I will be watching you channel.
I was at a tractor pull one time. The particular tractor had kind of a rail configuration. Engines hung way out front. On the end where a rad would have been, there was a steel block atou 3 to 4 feet square and 2 or 3 feet thick. Really heavy. The drive used a clutch. Every time the the driver revved the engine, it would lift the front wheels. The driver would then push in the clutch and it would drop the 3 or four feet down to ground level. This happened three times. The fourth time the engines said enough and started to disintegrate inside. Nothing really to see on the outside except the whole front of the tractor making left, right, up, down movements like a dog playing with a toy. Considering the mass of the steel block, engines, frame wheels etc I can't imagine the forces that were exerted. It was the hit of the show for us! Perhaps not for the driver.
I Still have 2 ratchets of my wrench days with their internals busted and been wanting to get new gear sets for them lol. Is that somthing I could just order myself with the model numbers? They around 2008 year slim neck models.
@@jimbrooks5496 Was at semi drags a few weeks ago. Old 60 Kenworth K100 cabover with a big cam cummins money shifted. Shook the stands. It was loud and was like staring into welding arcs
Eric you are really good at what you do sir. Every time I watch the breakdown of a engine with you I know in my heart you are the guy that belongs in this type of business and at this time we also want to thank your Mom and Dad for doing a super job raising you. God bless.
I wonder if given the low miles, the oil "expired" by time rather than mileage. Maybe thickened/sludged in the pan. Improper oil flow, a spirited drive, kaboom.
@@MrDrmorbid Also the sludge doesn't appear to be stuck to the metal,if that were normal unchanged oil sludge I would think it would stick,probably formed after the engine sat with antifreeze water down in the oil.
Merry Christmas Eric!! Thanks for the content that is exceptionally well made!! *edit: now that i know that eric's parents got him this, i gotta say a huge thanks to his parents for raising someone so awesome!*
I've replaced most of my "burn time" with your channel's content to slowly make myself more confident around engines as I slowly work towards my first swap. World class content :)
Thanks to Eric's Mom and Dad! It's very nice of you to pick this engine up for Eric. He did a great job of ripping it apart and analyzing the damage. Eric- you're the man when it comes to tearing down engines. God bless you entire family this Christmas.
First-time watcher of your channel. I did a bunch of wrench work when I was in high school, 1961-65, on mostly Chevrolet engines and I really enjoyed your comments and humor as you went through this teardown. I was amazed at the size of the viper engine. You are informative and fun to listen to. I have subscribed and will watch again. Thanks.
1997 Dodge Ram 2500 with V10. I was driving down I-35 going South. This truck never gave a single problem. Pulling an empty 16 ft trailer and was going downhill. A quick rattle and boom. It was still running as I pulled over. My wife came down in my 1991 chevy suburban. Trailer on the chevy I started and drove the ram onto it. The keepers on one intake valve had stripped off the locking lands so it ate a valve. I started it and drove it off the trailer. 4 pistons were destroyed. One head had a valve shoved through it. Everything was too damaged to repair. Had 167,000 miles on it.
I love that your parents help with bad decisions. BTW Merry Christmas to your family and all the viewers! Edit: I spy a RX-7 FB in the background, I ran one into the ground from 55K to 175K before the list of problems just didn't make economic sense. I drove it like I stole it for five years (1990 to 1995) with only small problems. Good times all in all.
I love this stuff. The time lapse is very good. Takes quite some to disassemble an engine especially when you're diagnosing the cause of failure. You never know what issues the thing had when it stopped running. Nice to know what's good or scrap. Excellent work.
Gen 3 viper engines are known to have poor oiling to the mains when cornering hard (You can see videos of people dropping oil pressure in the curves). The 4th gen 8.4 engines switched to a swinging pickup design which more or less fixed the issue. Funny thing is the viper V10 basically started life as a stretched LA v8 engine, so let's just say that engine was getting back to it's roots. I really dug the anti-wear skirt that one piston had!
Holy shit, I've seen you tear down a lot of engines, but this one takes the cake, and I think the person who was driving this when it happened knew how extensive the damage could be, this much damage makes a lot of heart stopping noise, it was very generous of you to say what you did, but like you said you pulled the trigger on it and this is all parr for the course of your business. I really enjoyed this one...thanx
Looks like the leaf was the killer. Your editing is fantastic,man. Thanks for your time and effort,thanks to your parents, I knew they’d done an excellent job from watching the first video I watched on your channel.
It’s a Christmas Miracle! If there’s one thing I’ve noticed, it’s that when a “performance” oriented engine lets go, it usually lets go BAAAAADDD. Like, super bad. This was certainly no exception to that rule. Have a great holiday period, Eric and best wishes to you and your family. This channel’s been a weekly go-to for me for well over a year and I love the content.
That's because when things go bad, engines direct the power they're making at themselves. Performance engines can make a lot of power, and things usually go bad when they're doing it really well ;)
I thought the more interesting thing was that for most of the video there were two wrist pins but only one rod. My imagination goes wild with things like that. Where the fk is the rest?? It has to be here somewhere! 🤣
One of your best tear downs. I enjoyed how this engine seemed simple compared to some of the OHC engines you've taken apart. I hope you make some good coin selling the parts. (:
For me, the money shot was at 41:29---I have never, ever seen a piston skirt look like that. I'm sure this one was dead silent when it came apart....NOT! Happy holidays, Eric!
I think you're onto something with the leaf and oil starvation/low level. However it got in, if it happened to flatten out on the screen, that's a pretty big part of the pickup being restricted. But that's all speculation! In any case, loved the video. I hope you have a great holiday with your family!
Seeing as almost every single bearing surface looks to have been oil starved, along with the blueing on the small rod end, im willing to bet it got oil starved on a full throttle pull and just obliterated itself. I think someone was changing the oil on a windy day and missed a leaf falling into the oil fill!
I’m shocked how little coolant is brought around the cylinder sleeve!! I shy away from all American made autos now…Japanese n German engineers take care of the little things (that become the BIG things later on). 🏎️G35 Gang
This is about the sixth of your videos that I've watched so far since finding them yesterday. From "come here, spark plug" in one to "you guys know the drill" in this one, I knew I'd found my kind of place. The teardowns are fascinating, too.
Judging by the condition of this motor you'll probably have its replacement for next year! Marry Christmas to your whole family and especially your new addition!
The smallest things can cause the biggest problems. That leaf was wedged deep in the oil pickup where most people would never have found it. An amazing discovery and a plot worthy of the best crime drama!
"See if there's malice in the compression palace?" Pure art on your part. Did you know listening to your vids while sick is therapeutic? Something satisfying about the whiz twirlers.
Dude you have this tear-down thing to a silence that is priceless to watch - That Viper engine is a one of a kind wish I could have been sitting in the seat and hear that pup come apart - bet you could hear it a mile away! Thanks Mike
The viper engine is an awesome beast, if you ever get a later 8.4 engine in i'd be very interested in the camshaft and cam phaser. They're a special design that is unique to that engine.
8.4 cams are unique and require a cam phaser, none of the engines he's torn down has it. The camshaft itself is actually two cam's in one and has the ability to vary the exhaust timing and thus valve overlap. They had the option to independently vary the intake and exhaust timing but didn't go for it as they said it would create too much 'tire smoke' (low end torque) and would cost a little more for the phaser but would need an uprated clutch, gearbox, prop-shaft, differential and drive shafts to handle the extra torque. Rumour has it they broke all of the above during testing and detuned the viper for production. It was only when they put the engine in a challenger drag pak that it was fully unleashed, if you haven't seen it look up the '11 Challenger drag pak, it has all the trans upgrades to handle the toque monster.
@@keithwalton the engine found In the drag pack challenger is heavily reworked compared to the engines found in the vipers. Everything apart from the short block is different.
Another great tear down. I’m going to take a guess that after the initial explosion the driver attempted to keep driving the car even though there was zero oil pressure. Thus the extent of main bearing damage in addition to the initial detonation.
I just want that piston pin. I imagine that the rev limiter was unplugged and at 10,000 rpm with a hundred psi oil pressure with a leaf indy pick-up, could've cause this damage. The oil starvation theory looks very legit.
Damn. The broken wrist pin is something I never thought I’d see. Probably watched about 50 hours of your videos this week and didn’t expect to see that. Love the channel!
What a gorgeous looking engine, such a waste. Thanks for the tear down merry christmas and happy new year to you all. P.S. Eric you know how we all hate to see the carnage and bits in an engine that has had a miss hap.🤨😉 it would be a fascinating tear down of one of these highly tuned tractor pulling engines that let go under full power. be impressive to see just how many parts it creates.(diesel)
Yeah, that part where he put his hand over the one damaged crank... God damn but that is sad, because I mean, just look at the rest of the surfacing, the oil, inside the cooler pump, the cam drive... That engine was properly built and looked after. Such a tragedy and unfairness to the owner.
I’m a New subscriber. Hello from Lubbock Texas. I find these very interesting. Your parents are a Blessing. God Bless you and your family. My Dad passed away last month and he Did so much for me .
Thank you! The Viper has always been sort of a guilty pleasure for me (three generations of GM mechanics in my line all frown on me for anything MOPAR). The late nineties and early aughts were a very bad time for American muscle in general - the cars were ugly, they didn't have a lot of power, and we were just starting to come into the modern era combining both power and fuel efficiency in a way that really mattered. Nothing else holds a candle to it throughout its run, up until the aftermarket performance of the LS7 and the Ford Trinity of 2013. Combined with the overwhelming usage of routine parts that fit that generation of 5.7 Hemi, and you have yourself a car that the average joe could actually keep up with in maintenance while having unrivaled domestic power, plus the aftermarket has a field day with an incredibly stout block and virtually indestructible stock internals. Emphasis on 'virtually.' This teardown was an incredible view into how catastrophic these engines can fail without being visually apparent. I mean, we have seen inspection ports large enough to pass your arm through, broken crankshafts, dropped valve seats... but to have an engine that was visually sound from a 5 foot inspection yet at the same time managed to destroy a WRIST PIN? The Black Box of the engine? The most indestructible feature of any rotating assembly? That, to me, just speaks to the power and the durability of this motor. This was an amazing teardown.

To me the Viper V10 was just Dodge's way of admitting that at the time their V8 was down on power compared to GM and they just had to throw more cylinders at it to fix the problem. Also I don't know much about Mopar in general but isn't the V10 based on the LA series smallblock with the Magnum upgrades? This would make it comparable to the 1992 GM LT family which was the bridge from the original smallblock to the LS that everyone loves that came out in 1997. As such, is this parts compatible with the Hemi? This engine debut way before the modern Hemi. I just don't know. Consider this. The 8.0 V10 Viper debut in 1992 with 400 hp so easy math 50 hp per liter. Convert that to a 350 V8 and you have yourself a 285 hp V8. In 1992, not that special. The 1992 Corvette was factory rated at 300 hp.
@@joshuahedrick What in 1992 besides a Corvette had 285 horsepower? Even by your logic that’s still a good number. The LT1 was about it. If there were more than 3 production engines in 1992 that made 285 horsepower I’d be surprised. They used a V10 because the torque curve and powerband is completely different than a V8 of the time. It’s a lot more than just comparing horsepower and number of cylinders. It was a Lamborghini design. Even if you cut two cylinders off that motor would still embarrass an LT1. LT1 is just a small block with heart shaped combustion chambers and reverse cooling. That’s it. And let’s face it, the LT1 was a junk motor. They could make some power, but they were a completely shit design.
@@GMbowtie350 A few points. The C4 Corvette ran for 12 model years. The LT1 replaced the 230-250hp TPI L98, which still made more power then any of Ford or Chryslers standard production V8. The LT1 made 300 hp standard in the 1992 Corvette, and GM later upgraded to the blueprinted LT4 making 330 hp naturally aspirated, and that could be ordered in any Corvette, not just the Grand Sport. Cutting 2 cylinders off the V10 would not embarrass a Corvette because the V10 was more similar to the LT5. What I mean by that is Chrysler had a stake in Lamborghini and let them do the tuning. At it's heart it was still an LA Chrysler engines with 2 cylinders added. Similarly GM had a stake in Lotus and developed the 375-405hp DOHC LT5 Side note GM introduced the LT5 Corvette 2 years before the Viper launched. Yes, the Viper was a faster car and a better performer. But I never said it wasn't a great car. My original statement stands, I feel like the V10 was created because Chrysler didn't have a powerful enough V8 to stick in there. The 1992 Viper v10 had 2.3 liters more displacement then any of the smallblocks GM was putting into their cars. Of course it was going to make a boatload of power and torque. They thew more cylinders and more displacement at their design to make more power. Nothing wrong with that GM and Ford do the same thing. I'm just stating that even in 1992 it wasn't that hard to achieve 50 hp/l GM chose to use the LT5 to help design the LS series engines and eventually going with forced induction in their top dog V8
@@joshuahedrick Dodge didn’t need a V8 to outrun the Corvette. The Stealth RT did it with 6 cylinders and a turbo. Not sure why you gave a history of the C4 but ok. We’re not talking about the LT4 in ‘96. Numerous other cars broke 300 horsepower by then. We’re talking 1992, you said it wasn’t anything for a motor to make 285 horsepower in 1992 so other than the LT1, Stealth RT/3000GT VR4 that I mentioned, or the Viper what in 1992 made over 300 horsepower. My point is in that particular time power was down across the board. Almost all performance cars hovered in the low to mid 200 horsepower range.
@@GMbowtie350 I gave you a history of the C4 Corvette because the LT5 debut 2 years before the Viper in 1990 with 375 hp, and would have made more that year if stupid GM hadn't forced Lotus engineers to go from a 4.55 bore spacing back to 4.4 You think I'm bashing the Viper and the V10 but I'm not, I'm saying from my point of view Chrysler could not keep up with GM V8 so they went with an enlarged 10 cylinder engine with 2.3 liters more displacement then the competition. The main domestic competition to the Vuler was the Corvette. And as a whole pacage the Viper was better. But the V10 engine wasn't some miracle of engineering like you seems to think it is. It was a heavy engine and not as power dense as comparable GM v8 engines of the same time period.
Often on the Viper engine, what causes many of the catastrophic problems, Starts from a cracked exhaust manifold. as you will see, the one manifold you pulled is cracked right at the O2 sensor. That throws the mixture out of wack, then if not repaired, the problem escalates.
Ok, this is engine teardown #3 that you somehow got me to watch! Your mannerisms and expressions absolutely crack me up :-) Thanks for doing this video - on Christmas Eve no less! My favorite parts are when you speed your voice up. Keep up the great work.
1st time i hve seen a complete engine teardown video. Just amazing. i am speechless on the quality of production and close up of almost everything that i wanted to see. just amazing, who ever is handling the camera, props. amazing job. i am a sub now. doing what u do is a dream. thank you for an amazing video. i subd.
As bad as it might look, it's likely still salvageable. I just did the exact same thing on my car (shattered a rod), and I just finished rebuilding it. You can resleeve them and fix most of the damage as long as the oil galley is okay
Hi Eric. Great post - really enjoyed the excitement of exploring the Viper and finding the devastation as you stripped her down. I muttered a few expletives myself as you stripped her down. Just subscribed for more. 😊👌
I'm just super thankful for everyone that made this possible. This is an amazing feat of a community... What you've done has improved a not insignificant piece of many lives. The spark plugs are a fair representation of the support received by the creator of this content - no one gave up.
Was the car stolen? It was certainly spinning at a fair clip when it let go, and it seems even then was shown no mercy. I wonder how much power it made as a v8? Definitely a worthy teardown. Many thanks to your parents as well Merry Christmas to you and your whole family.
I think it’s fitting that you keep going front to back and then back to the front on the Viper motor. They seem like the kind of engines that don’t mind that.
So many twists in this episode! The broken wrist pin, the perfect water pump that did not get yeeted across the shop! What an emotional roller coaster. ;-)
your commentary made the viewing of this UA-cam video very entertaining. I appreciated your sense of humor. I also appreciate the design and craftsmanship that goes into a high performance internal combustion engine. one clearly sees how a very expensive toy was abused and suffered a catastrophic failure. Some people have money to burn. of course their wastefulness helps fuel the salvage industry in general
Just a heads up. That large channel just above the main bearings is one of the main oil galleries. It has a nice big cut in it. It's likely a rod bolt worked loose or something and damaged the main oil gallery causing a low oil pressure state. This could cause a majority of the damage seen in the engine.
Good post and great final recap of what could have happened. All of us who love to take on challenges, whether cars, machinery, guns, clocks, etc have like experiences with the items and every challenge is a learning experience. Happy new year!
Thank you Eric's mom and dad. First for making him and raising him to be a fine upstanding citizen and for going to pickup the Viper engine for this week's video.

@@dav1dsm1th You'd think that someone would have a dashcam or a GoPro running that could catch the... interesting metal on metal internal conflicts...

Piston Nuggets and Special Sauce! As a retired mechanical engineer, I truly enjoy the diagnosis, failure analysis and possible root cause failure points. I enjoy your running commentary on disassembly procedure. You are fun to listen to and a great instructor. I have learned much from your videos. This channel rocks!
It would be interesting to clean up the internal debris and arrange it in as-close-to original positions as possible, as they do with some crashed-airplane reconstructions. He did some of it with the exploded rod, but I would like to have seen the pieces of the piston laid out too. A bit of a jigsaw puzzle.
-- Also, I think in tear downs like this, it would be good to have a little slab made of 2x4s, to slip onto the base of the engine stand for the moments of last-bolt removal, when a part is likely to fall onto the base or the floor. Just something to soften the initial impact. A couple of short 2x4s could also have supported the intake manifold when he was trying to sort out the last electrical connections.
@@grizzlygrizzle I like your comment. It brought to mind that wooden pallets like the ones shippers use. Cheap, reusable, not hard to store.
I agree.. Eric makes the videos worth watching with his expressions of surprise and shock at what he finds.
After watching a few of your engine teardowns, I'm going to start checking my oil more regularly!
"re-gapped" spark plug! Priceless!
What we really need is an engine with all kinds of carnage that comes complete with video of either the noise it was making before, or the noises it made *when* she blew.
Like a real video of last few minutes of when it was last run in stereo.
Maybe a cool b/s, to possibly Include. 5w's who,wut,wen,where how?..heh.
I'd love to see a teardown of that runaway diesel that's been going around on YT/social media, the one from some car show where you can see the block literally glowing from the wheel wells.

At Christmas time we can all agree on one thing, red locking tab chrysler connectors should be outlawed
F I A T
@@chungusamongus519 no?
Locking tabs on electrical connectors are hardly just a Chrysler phenomenon, and I personally don’t understand the hate for those specific connectors considering how easily they come apart relative to other types of locking connectors.
Agreed. Cummins uses them too on some of their engines. I deal with a lot of B/ISB/QSB6.7 engines, and they're always on the EGR and valve cover, and a few other things. They really suck.
I drive a 2010 Pt and usually I just unscrew or remove whichever sensor rather than messing with those locking clips, trying to undo those things is like trying to separate two pieces of tissue paper that are superglued together without ripping either one
Years ago when I was a tech for Mercedes Benz in my hometown, a customer from a Dodge dealership came to us and asked us to tear down the engine in his viper and rebuild it for him, and he wasn't interested in how much it would cost him, so we did it. there was a considerable amount of damage in the engine, mainly the crankshaft bearings, we did some tests and found out that the engine had well over the .030" clearance that would keep the engine safe from problems of excessive clearance. the engine had less than 20,000 miles and it is likely that the engine had been built from Factory with the Maximum allowable clearance, so that the engine would be putting out lots of power, unhindered by tolerance that were too close. I knew that this was a tactic that many race crews used to make their engine perform well on the track, but those engines were always rebuilt after each race. But this is what Dodge did with factory engines! and the limit on the Viper power train warranty was 25,000 miles! they knew the engines wouldn't last and tried to cover their arses, and although this guy's viper was still under warranty, they accused him of excessive abuse of the engine and refused to honor the warranty, but this guy wasn't gonna have it. he told us to make every change necessary and not to spare any cost nor should we try and make any deals for him, he said he was going to sue Dodge for the repairs and make them pay for the bill. So we made that viper engine tight and within spec of .010" clearance on the mains and the various clearances of the standard 340 v-8 and the viper v-10 is just a copy of the 340 with two extra cylinders added to the rear of the block. we put it back together so well, in fact that the guy came back years later and said he had never had as reliable an engine from Dodge in his life, he had well over 115,000 miles of the engine and it was still going strong. it wasn't as powerful as it was before but he said that it was alright anyways because he had a good engine. He sued Dodge, and won, and the tab was picked up by Dodge, and that was during the years when Dodge/Chrysler was being dragged into court kicking and screaming for not honoring their warranties like they were bound to by law. one of the many reason why Dodge Chrysler was sold to FIAT to stop them from gong Bankrupt again! My advice to anyone is to stay away from Chrysler products entirely, the company has had so many times been such a poorly operated and terrible customer service driven corporation that it just doesn't make any sense to trust them. I could fill you with stories I have come across as an auto tech about Chrysler and how they operate that I would NEVER buy any Chrysler product, ever. The biggest problem is that they make nice looking vehicles, and that lures far too many people in to buy their junk. Hopefully Fist can turn them around but if Mercedes Benz couldn't do it when they owned them, I doubt Fiat can do it either.
Only issue I've had is with the hemi, and the common lifter issue but I don't mind doing the work myself which I have. I'll always stick with their products. I run my stuff hard and I love the 5.7. Hearing all these stories though about the viper engine, no thanks
.030" is allowable? I build race engines that are .010 max... usually .003-.005 is allowable. That's nuts.
Sounds to me like the inginerds did their part, but then management got involved to help uhh... "fix" things. For the marketing department, you see! Because middle managers with MBAs _always_ know better...
What differences in power are we talking about?
@@mojoblues66 I wouldn't be surprised if it's as much as 10% or more. Parasitic loads are a huge thing in engines. That's basically where all your engine braking comes from. That and a little bit of entropy in the compression cycle, but that's negligible compared to the parasitic loads.
I'm sure you've heard about thermal efficiency of combusion engines, and that the Otto cycle is 15% while the Diesel cycle is about 45%. That's foe the thermal cycle only though. In other words, it's all the energy you could ever possibly get out of the fuel you put in.
Then come the parasitic loads. Oil pump, water pump, valve springs, HP fuel pump (if present), all the friction from the sliding contact inside the cylinders, plus all the auxiliaries - alternator, AC compressor, power steering pump... hell, even the bearing grease inside the idler pulley's bearing. These things all add up to sap a bunch more power out of your engine. Then there's a 10% loss from the drivetrain components on top of that (assuming a manual gearbox, more if it's a slushbox)... By the time you get to the wheels, you're looking at closer to 10% from the Otto cycle, 30% from the Diesel cycle.
If you can do something about those parasitic loads (such as loosening up all the bearings), you'll get some measurable benefit. Probably even measurable by your average arse dyno.
If he's having that much trouble with the intake manifold with the engine out of the car, then having to take it off in the car would be a nightmare.
Piston nuggets, bearing foil, and multi-cylinder connecting rods! Eight cylinders seem pretty good looking; maybe someone will want a Viper V-8?? Honestly, I'm impressed this engine didn't completely grenade with tennis ball size exit holes in the block. Thank you for sharing; it was interesting to see how this engine is assembled.
That block cleaned up would honestly make a pretty good coffee table, You could probably sell it for a pretty penny too.
Top gear did. I bet he could sell it for some pretty good money. Strange but true.
I'd buy it
I’d buy it too, but the wife would not let me put it in the family or living rooms.
@@toobalicious The bedroom it is then!
I was thinking it would make a "one of a kind", expensive boat anchor.
Gone from V10 to V8 in the blink of an eye 👀
More like a v0 theres no way that ran
@@colchronic The owner told Eric it still did....
@@mtut yeah i wrote that before that part. Anyways like eric, i find that hard to believe 🤣
@@colchronic hard to believe indeed
@@colchronic i've known about v8s that ran with 2 cylinders having 0 compression for some time so it's not unlikely it could be still running but it's definitely not going to be running good
Edit: upon completion of watching the video i have revised my opinion on this engine... it definitely did not run
In my tenure in the shop I rebuilt close to 400 engines and I’ve never seen that much carnage in an engine. Merry Christmas to you and yours Chris! Tell your parents thank you for bringing this Christmas present to your shop!
This was never a rebuild project. lol
Owner never changed the oil, once.
If you think this much carnage was bad, head over to the Steve Morris channel and check out his video on his 4k HP engine where all 8 rods exploded at the same instant.
if you want to see carnage check out steve morris's channel where all 8 rods exploded.
@@aSinisterKiid Link?
I was part of a 5.0l engine tear down at CEP#1 in the early 90's. Our plant required that any engine deemed defective had to come back for tear down before a new engine was released. This engine was a 5.0l Mustang, which was ironically owned by a Ford employee. When the intake manifold was removed we found the foil seal off of the oil container lying in the tappet valley. Enough said, I'm pretty sure the leaf you found was the cause of this V10 blowing up. Great videos keep them coming.
Thanks!
Merry Christmas Eric. I'm not a mechanic or a car guy but I'm glad I found your channel. Love your content and you have made me think about how I'm taking care of my car.
As a retired engineer I love watching these videos! I've loved cars and racing them for the past 20 years and getting to see the internals of a bunch of different engines really tells me a lot about the engineering that went into them. You can just about see the philosophy that went into the design. With the Viper we have an old school V8 that they want more power out of but have hit the limit of the block design, so let's just add two cylinders. But let's keep it old school simple: single cam with pushrods, no oil squirters up the bore to cool the pistons which would complicate the block casting. Just a 25% longer block and cam. What could be easier? Thanks, Eric, really enjoy these videos!
You just answered my piston oil squirter question, thank you
This was exactly my thoughts when I compare this to a 12 cylinder Mercedes engine you already have difficulties dismantle the engine it is so complex
I watched a documentary on Ford's Formula 1 engine development from just a few years earlier than the Viper was conceived, and it makes sense to me now why companies used to do silly stuff like this (or what seemed silly to me). Cosworth tried using an existing factory Ford engine block to develop the race engine out of but the webbing turned out to be too weak and the crank would distort at high RPM. They had to go with a clean sheet design and the movie went through the whole engine development process of a new V6. It was so expensive to CNC machine a casting mold in that era that they still opted to have people hand carve them out of Brazilian mahogany. Needless to say it was insanely expensive to go through this process, not to mention all of the tooling they would inevitably have to adapt the design to in order to mass produce any new engine on the same assembly lines as other ones in the fleet. Slapping an extra pair of cylinders on the end of a truck V8 starts to make sense now. Same with the 90 degree V6's that were based on V8 engines. I still think as a long term strategy it hurt all of the domestic OEMs to design engines this way, but at least you can see their line of thinking. They were concerned with quarterly and annual reports, the short term profitability that effected their images and bonus pay in the short term.

I was a technician for 17 years before I bought a Snap On Tool business. I have seen some really bad engine detonations but by far this Viper V10 engine was just mind boggling with hundreds of questions. I only wish I could have heard it explode. Rainman sent me to your sight and by far you do such a great job I will be watching you channel.
Snap On tool business? You must be a rich man!
I was at a tractor pull one time. The particular tractor had kind of a rail configuration. Engines hung way out front. On the end where a rad would have been, there was a steel block atou 3 to 4 feet square and 2 or 3 feet thick. Really heavy. The drive used a clutch. Every time the the driver revved the engine, it would lift the front wheels. The driver would then push in the clutch and it would drop the 3 or four feet down to ground level. This happened three times. The fourth time the engines said enough and started to disintegrate inside. Nothing really to see on the outside except the whole front of the tractor making left, right, up, down movements like a dog playing with a toy. Considering the mass of the steel block, engines, frame wheels etc I can't imagine the forces that were exerted. It was the hit of the show for us! Perhaps not for the driver.
I Still have 2 ratchets of my wrench days with their internals busted and been wanting to get new gear sets for them lol. Is that somthing I could just order myself with the model numbers? They around 2008 year slim neck models.

Eric you are really good at what you do sir. Every time I watch the breakdown of a engine with you I know in my heart you are the guy that belongs in this type of business and at this time we also want to thank your Mom and Dad for doing a super job raising you. God bless.
Great camera work and video editing. Fun to watch you and learn. Dry humor and double-entendres make it even more fun. Thanks for all you do.
I find it amazing that an engine that is so clean on top has fatal sludge in the oil pan.
Maybe the oil never made it to the top. lol
I wonder if given the low miles, the oil "expired" by time rather than mileage. Maybe thickened/sludged in the pan. Improper oil flow, a spirited drive, kaboom.
@@polarys425my thoughts exactly
The sludge at the bottom end is typical of oil just left sitting for years. From the way the engine looks, it's just likely condensation and such.
@@MrDrmorbid Also the sludge doesn't appear to be stuck to the metal,if that were normal unchanged oil sludge I would think it would stick,probably formed after the engine sat with antifreeze water down in the oil.
Merry Christmas Eric!! Thanks for the content that is exceptionally well made!!
*edit: now that i know that eric's parents got him this, i gotta say a huge thanks to his parents for raising someone so awesome!*
NICE! These engines are so badass! Merry Christmas to all the fans of this channel.

Thanks to Eric's Mom and Dad! It's very nice of you to pick this engine up for Eric. He did a great job of ripping it apart and analyzing the damage. Eric- you're the man when it comes to tearing down engines. God bless you entire family this Christmas.
Thank you Eric for your channel; love your sarcasm and the teardowns. Merry Christmas to you and your family!
okay, that was carnage-tastic.
I kept imagining the moment of failure - all that motion and kinetic energy all going pear-shaped. Pretty awesome.
First-time watcher of your channel. I did a bunch of wrench work when I was in high school, 1961-65, on mostly Chevrolet engines and I really enjoyed your comments and humor as you went through this teardown. I was amazed at the size of the viper engine. You are informative and fun to listen to. I have subscribed and will watch again. Thanks.
1997 Dodge Ram 2500 with V10. I was driving down I-35 going South. This truck never gave a single problem. Pulling an empty 16 ft trailer and was going downhill. A quick rattle and boom. It was still running as I pulled over. My wife came down in my 1991 chevy suburban. Trailer on the chevy I started and drove the ram onto it. The keepers on one intake valve had stripped off the locking lands so it ate a valve. I started it and drove it off the trailer. 4 pistons were destroyed. One head had a valve shoved through it. Everything was too damaged to repair. Had 167,000 miles on it.
Merry Christmas to you and the family Eric.
Thanks for all the awesome content.
You do a great job editing the time lapse to keep the video moving without losing any detail! Well done!
I love that your parents help with bad decisions. BTW Merry Christmas to your family and all the viewers!
Edit: I spy a RX-7 FB in the background, I ran one into the ground from 55K to 175K before the list of problems just didn't make economic sense. I drove it like I stole it for five years (1990 to 1995) with only small problems. Good times all in all.
The only proper way to run an RX-7
I hope you had a really nice Christmas with your family. This is the first time I've seen a Viper engine. It certainly opened my eyes.
I love this stuff. The time lapse is very good. Takes quite some to disassemble an engine especially when you're diagnosing the cause of failure. You never know what issues the thing had when it stopped running. Nice to know what's good or scrap. Excellent work.
Gen 3 viper engines are known to have poor oiling to the mains when cornering hard (You can see videos of people dropping oil pressure in the curves). The 4th gen 8.4 engines switched to a swinging pickup design which more or less fixed the issue. Funny thing is the viper V10 basically started life as a stretched LA v8 engine, so let's just say that engine was getting back to it's roots. I really dug the anti-wear skirt that one piston had!
Cornering hard ... is that possible?
Always great when the engine doesn't lubricate well in a situation it will find itself very often in...like hard cornering in a Viper...
@@psk5746 Vipers can turn, man :v
Allen Millyards' Viper bike doesn't have that issue.
Holy shit, I've seen you tear down a lot of engines, but this one takes the cake, and I think the person who was driving this when it happened knew how extensive the damage could be, this much damage makes a lot of heart stopping noise, it was very generous of you to say what you did, but like you said you pulled the trigger on it and this is all parr for the course of your business. I really enjoyed this one...thanx
Merry Christmas my dude! I’m looking forward to another year of content from ya
That exhaust manifold is a work of art ❤
And to cover it with that heat shield 😢
Looks like the leaf was the killer.
Your editing is fantastic,man.
Thanks for your time and effort,thanks to your parents, I knew they’d done an excellent job from watching the first video I watched on your channel.
Whoa! I haven't torn down anywhere near the engines you have. That's the first wrist pin I've ever seen that was damaged at all let alone broken.
It’s a Christmas Miracle!
If there’s one thing I’ve noticed, it’s that when a “performance” oriented engine lets go, it usually lets go BAAAAADDD. Like, super bad. This was certainly no exception to that rule.
Have a great holiday period, Eric and best wishes to you and your family. This channel’s been a weekly go-to for me for well over a year and I love the content.
That's because when things go bad, engines direct the power they're making at themselves. Performance engines can make a lot of power, and things usually go bad when they're doing it really well ;)
The wristpin is by far the most amazing thing about this engine
And might have been the source of a lot of the destruction - high speed industructable object meets stationary immoveable object(s).
What I said. They usually don't suffer that kind of damage. Don't know if those are full float pins or not
I thought the more interesting thing was that for most of the video there were two wrist pins but only one rod. My imagination goes wild with things like that. Where the fk is the rest?? It has to be here somewhere! 🤣
@@LtJackboot reduced to atoms
One of your best tear downs.
I enjoyed how this engine seemed simple compared to some of the OHC engines you've taken apart.
I hope you make some good coin selling the parts. (:
Yes, scrap metal
Back at ya, I love all your tear downs. The Viper was a special treat👍.
That was a treat of a tear down. It takes some heat to have look like it was melted down the side of the piston skirt.
For me, the money shot was at 41:29---I have never, ever seen a piston skirt look like that. I'm sure this one was dead silent when it came apart....NOT! Happy holidays, Eric!
I think you're onto something with the leaf and oil starvation/low level. However it got in, if it happened to flatten out on the screen, that's a pretty big part of the pickup being restricted. But that's all speculation! In any case, loved the video. I hope you have a great holiday with your family!
Seeing as almost every single bearing surface looks to have been oil starved, along with the blueing on the small rod end, im willing to bet it got oil starved on a full throttle pull and just obliterated itself.
I think someone was changing the oil on a windy day and missed a leaf falling into the oil fill!
@@HumbleHonkingEnthusiast You must have read my mind. I was thinking the same thing before I read your comment.
Can you imagine a 26K Viper engine being taken out by a leaf? I think I’m going to cry.
I’m shocked how little coolant is brought around the cylinder sleeve!!
I shy away from all American made autos now…Japanese n German engineers take care of the little things (that become the BIG things later on).

Judging by the condition of this motor you'll probably have its replacement for next year! Marry Christmas to your whole family and especially your new addition!
The smallest things can cause the biggest problems. That leaf was wedged deep in the oil pickup where most people would never have found it. An amazing discovery and a plot worthy of the best crime drama!
"See if there's malice in the compression palace?" Pure art on your part. Did you know listening to your vids while sick is therapeutic? Something satisfying about the whiz twirlers.
Dude you have this tear-down thing to a silence that is priceless to watch - That Viper engine is a one of a kind wish I could have been sitting in the seat and hear that pup come apart - bet you could hear it a mile away! Thanks Mike
It's amazing how much damage an engine can take and still run! Awesome video!
The viper engine is an awesome beast, if you ever get a later 8.4 engine in i'd be very interested in the camshaft and cam phaser. They're a special design that is unique to that engine.
He already did a 8.4
@@earlscheib7754 Truck version, not Viper.
@@davidb6576trucks never got the 8.4. Hes done only 8.3l motors.
8.4 cams are unique and require a cam phaser, none of the engines he's torn down has it. The camshaft itself is actually two cam's in one and has the ability to vary the exhaust timing and thus valve overlap. They had the option to independently vary the intake and exhaust timing but didn't go for it as they said it would create too much 'tire smoke' (low end torque) and would cost a little more for the phaser but would need an uprated clutch, gearbox, prop-shaft, differential and drive shafts to handle the extra torque.
Rumour has it they broke all of the above during testing and detuned the viper for production.
It was only when they put the engine in a challenger drag pak that it was fully unleashed, if you haven't seen it look up the '11 Challenger drag pak, it has all the trans upgrades to handle the toque monster.
@@keithwalton the engine found In the drag pack challenger is heavily reworked compared to the engines found in the vipers. Everything apart from the short block is different.
Another great tear down. I’m going to take a guess that after the initial explosion the driver attempted to keep driving the car even though there was zero oil pressure. Thus the extent of main bearing damage in addition to the initial detonation.
I absolutely love the fact that I am not the ONLY guy who closes his eyes, says "It'll be OK" 3 times and gives 'er a whack! Love your videos !
Thank you dad and momma. This is a treat! Also sweet channel bud
I just want that piston pin. I imagine that the rev limiter was unplugged and at 10,000 rpm with a hundred psi oil pressure with a leaf indy pick-up, could've cause this damage. The oil starvation theory looks very legit.
Yeah she was at full send and then some when she blew. Must have a glorious noise upon destruction
Could imagine someone money shifted it
That engine was like a crime scene.
It was a bloody murder
Bro is like an engine archeologists. Straight up puts the pistons and rods back together like broken bones of a dinosaur
Damn. The broken wrist pin is something I never thought I’d see. Probably watched about 50 hours of your videos this week and didn’t expect to see that. Love the channel!
Crazy Man....what a tear down surprise. Love the content pls keep it coming. All the best for 2023. 🤟
What a gorgeous looking engine, such a waste. Thanks for the tear down merry christmas and happy new year to you all. P.S. Eric you know how we all hate to see the carnage and bits in an engine that has had a miss hap.🤨😉 it would be a fascinating tear down of one of these highly tuned tractor pulling engines that let go under full power. be impressive to see just how many parts it creates.(diesel)
Yeah, that part where he put his hand over the one damaged crank... God damn but that is sad, because I mean, just look at the rest of the surfacing, the oil, inside the cooler pump, the cam drive... That engine was properly built and looked after. Such a tragedy and unfairness to the owner.
I bet that the former owner of this engine must’ve been horrified about the amount of damage in that engine.
Would be interesting to see if the crankshaft is bent as well. That may explain the difficulty in removing it from the block.

I've never seen any of these videos before. Thorough, knowledgeable, humorous. I actually learned quite a lot!
Thank you!
The Viper has always been sort of a guilty pleasure for me (three generations of GM mechanics in my line all frown on me for anything MOPAR). The late nineties and early aughts were a very bad time for American muscle in general - the cars were ugly, they didn't have a lot of power, and we were just starting to come into the modern era combining both power and fuel efficiency in a way that really mattered. Nothing else holds a candle to it throughout its run, up until the aftermarket performance of the LS7 and the Ford Trinity of 2013. Combined with the overwhelming usage of routine parts that fit that generation of 5.7 Hemi, and you have yourself a car that the average joe could actually keep up with in maintenance while having unrivaled domestic power, plus the aftermarket has a field day with an incredibly stout block and virtually indestructible stock internals.
Emphasis on 'virtually.'
This teardown was an incredible view into how catastrophic these engines can fail without being visually apparent. I mean, we have seen inspection ports large enough to pass your arm through, broken crankshafts, dropped valve seats... but to have an engine that was visually sound from a 5 foot inspection yet at the same time managed to destroy a WRIST PIN? The Black Box of the engine? The most indestructible feature of any rotating assembly? That, to me, just speaks to the power and the durability of this motor.
This was an amazing teardown. Thank you for everything you do for us, and I hope you have a pleasant holiday season.

To me the Viper V10 was just Dodge's way of admitting that at the time their V8 was down on power compared to GM and they just had to throw more cylinders at it to fix the problem. Also I don't know much about Mopar in general but isn't the V10 based on the LA series smallblock with the Magnum upgrades? This would make it comparable to the 1992 GM LT family which was the bridge from the original smallblock to the LS that everyone loves that came out in 1997. As such, is this parts compatible with the Hemi? This engine debut way before the modern Hemi. I just don't know. Consider this. The 8.0 V10 Viper debut in 1992 with 400 hp so easy math 50 hp per liter. Convert that to a 350 V8 and you have yourself a 285 hp V8. In 1992, not that special. The 1992 Corvette was factory rated at 300 hp.
@@joshuahedrick What in 1992 besides a Corvette had 285 horsepower? Even by your logic that’s still a good number. The LT1 was about it. If there were more than 3 production engines in 1992 that made 285 horsepower I’d be surprised. They used a V10 because the torque curve and powerband is completely different than a V8 of the time. It’s a lot more than just comparing horsepower and number of cylinders. It was a Lamborghini design. Even if you cut two cylinders off that motor would still embarrass an LT1. LT1 is just a small block with heart shaped combustion chambers and reverse cooling. That’s it. And let’s face it, the LT1 was a junk motor. They could make some power, but they were a completely shit design.
@@GMbowtie350 A few points. The C4 Corvette ran for 12 model years. The LT1 replaced the 230-250hp TPI L98, which still made more power then any of Ford or Chryslers standard production V8. The LT1 made 300 hp standard in the 1992 Corvette, and GM later upgraded to the blueprinted LT4 making 330 hp naturally aspirated, and that could be ordered in any Corvette, not just the Grand Sport. Cutting 2 cylinders off the V10 would not embarrass a Corvette because the V10 was more similar to the LT5. What I mean by that is Chrysler had a stake in Lamborghini and let them do the tuning. At it's heart it was still an LA Chrysler engines with 2 cylinders added. Similarly GM had a stake in Lotus and developed the 375-405hp DOHC LT5 Side note GM introduced the LT5 Corvette 2 years before the Viper launched. Yes, the Viper was a faster car and a better performer. But I never said it wasn't a great car. My original statement stands, I feel like the V10 was created because Chrysler didn't have a powerful enough V8 to stick in there. The 1992 Viper v10 had 2.3 liters more displacement then any of the smallblocks GM was putting into their cars. Of course it was going to make a boatload of power and torque. They thew more cylinders and more displacement at their design to make more power. Nothing wrong with that GM and Ford do the same thing. I'm just stating that even in 1992 it wasn't that hard to achieve 50 hp/l GM chose to use the LT5 to help design the LS series engines and eventually going with forced induction in their top dog V8
@@joshuahedrick Dodge didn’t need a V8 to outrun the Corvette. The Stealth RT did it with 6 cylinders and a turbo. Not sure why you gave a history of the C4 but ok. We’re not talking about the LT4 in ‘96. Numerous other cars broke 300 horsepower by then. We’re talking 1992, you said it wasn’t anything for a motor to make 285 horsepower in 1992 so other than the LT1, Stealth RT/3000GT VR4 that I mentioned, or the Viper what in 1992 made over 300 horsepower. My point is in that particular time power was down across the board. Almost all performance cars hovered in the low to mid 200 horsepower range.
@@GMbowtie350 I gave you a history of the C4 Corvette because the LT5 debut 2 years before the Viper in 1990 with 375 hp, and would have made more that year if stupid GM hadn't forced Lotus engineers to go from a 4.55 bore spacing back to 4.4 You think I'm bashing the Viper and the V10 but I'm not, I'm saying from my point of view Chrysler could not keep up with GM V8 so they went with an enlarged 10 cylinder engine with 2.3 liters more displacement then the competition. The main domestic competition to the Vuler was the Corvette. And as a whole pacage the Viper was better. But the V10 engine wasn't some miracle of engineering like you seems to think it is. It was a heavy engine and not as power dense as comparable GM v8 engines of the same time period.
Best Christmas ever
Often on the Viper engine, what causes many of the catastrophic problems, Starts from a cracked exhaust manifold. as you will see, the one manifold you pulled is cracked right at the O2 sensor. That throws the mixture out of wack, then if not repaired, the problem escalates.
On extremely high performance engines like this, a lean condition can absolutely cause catastrophic failure. Good catch on the crack.
@@sHoRtBuSseR Wouldn't the computer go rich for an exhaust leak though?
@@Milkmans_Son typically I see lean codes with exhaust leaks
@@sHoRtBuSseR True but it would be a false lean condition so the computer adds (too much) fuel. I think.
@@Milkmans_Son ahhh you're right. I've been out of the gasoline side for about a year so I got a little rusty lol.
Ok, this is engine teardown #3 that you somehow got me to watch! Your mannerisms and expressions absolutely crack me up :-) Thanks for doing this video - on Christmas Eve no less! My favorite parts are when you speed your voice up. Keep up the great work.

Spinning big end of rod....
I've heard of a spun bearing, but that is ridiculous!!!!
1st time i hve seen a complete engine teardown video. Just amazing. i am speechless on the quality of production and close up of almost everything that i wanted to see. just amazing, who ever is handling the camera, props. amazing job. i am a sub now. doing what u do is a dream. thank you for an amazing video. i subd.
Most certainly happened at idle just after startup 🤣
So real low rpm
During cranking. On a weak battery...
@@davidb6576 Yeah, they come with a heck of a starter motor, lol...
Gotta be gentle with these delicate high perf engines when they're cold ( lol!)
As bad as it might look, it's likely still salvageable. I just did the exact same thing on my car (shattered a rod), and I just finished rebuilding it. You can resleeve them and fix most of the damage as long as the oil galley is okay
There's two holes on each side of the block
Curse you…. I watch your videos out of curiosity, the commentary, humor and sound effects…I’m addicted.
Love your videos and the humor you add is awesome! The more I see your work though - the more my desire to drive electric increases.
I can only imagine the sound this made when it exploded
That boy speed dialed AAA after. Complete blow up.
I think it said "bang". LOL

*driver, not the engine.
The Viper was such an awesome vehicle...so awesome it can break wristpins 🤣
For large metal parts that are damaged beyond repair, I would say that it has potential as a boat anchor.
I agree. The smaller ones would make great door stops, or paperweights.
Hi Eric. Great post - really enjoyed the excitement of exploring the Viper and finding the devastation as you stripped her down. I muttered a few expletives myself as you stripped her down. Just subscribed for more. 😊👌
I'm just super thankful for everyone that made this possible. This is an amazing feat of a community... What you've done has improved a not insignificant piece of many lives. The spark plugs are a fair representation of the support received by the creator of this content - no one gave up.
Interesting that all the frags stayed inside the engine block. Looking at the damage I would have expected some view holes in the block.
Was the car stolen? It was certainly spinning at a fair clip when it let go, and it seems even then was shown no mercy. I wonder how much power it made as a v8? Definitely a worthy teardown. Many thanks to your parents as well Merry Christmas to you and your whole family.
If the car was stolen, then it was stolen for quite a while with zero maintenance. It takes a while to build up that much sludge in the oil pan.
I think it’s fitting that you keep going front to back and then back to the front on the Viper motor. They seem like the kind of engines that don’t mind that.
Viper engines are a special kind of lady for sure. Freak in the streets and in the sheets
THAT'S WHAT SHE SAID 😅😅
So many twists in this episode! The broken wrist pin, the perfect water pump that did not get yeeted across the shop! What an emotional roller coaster. ;-)
your commentary made the viewing of this UA-cam video very entertaining. I appreciated your sense of humor. I also appreciate the design and craftsmanship that goes into a high performance internal combustion engine. one clearly sees how a very expensive toy was abused and suffered a catastrophic failure. Some people have money to burn. of course their wastefulness helps fuel the salvage industry in general
Just a heads up. That large channel just above the main bearings is one of the main oil galleries. It has a nice big cut in it. It's likely a rod bolt worked loose or something and damaged the main oil gallery causing a low oil pressure state. This could cause a majority of the damage seen in the engine.
The oil seams really thick, like someone put gear lube in the engine oil!
with the way it looks it didnt get oil changes i dont think it was take care of vary well
what a stupid location for the ignition coils. Many heat cycles and so hard to replace.
New name for Channel. The Engine Detective. Fascinating channel and description is clear and funny. Well done.
Good post and great final recap of what could have happened. All of us who love to take on challenges, whether cars, machinery, guns, clocks, etc have like experiences with the items and every challenge is a learning experience. Happy new year!
