@@creverett9ya but I think it would be really hard to argue that the engine broke due to their issue and not something you did to it. Like no break in period etc etc no oil blah blah. It probably would have broken pretty soon after engine start due to the wrist pin missing but who knows what else it would have taken with it when it dies.
@@warnabrotha95YTwell yea obviously not since it's brand new, no actual reason for your average Joe to tear it apart for funzies, terrible quality control lol that's why American is trash nowadays
The first thing you need to do with the next engine is tear it down and look for problems! Then, after the truck project is done, use both crate engines in a new HI / LOW project where you start with identical engines instead of identical cars.
This is insane. When the video started, I was thinking "there's no way I'd take apart a freshly build engine that was done by professionals". After what you found, I'd be measuring the bores, getting a straight edge on the deck and heads, checking the ring gap, and weighing each of the pistons. And I'd do the same on the new engine too. Excellent video, please do keep us updated on anything else you find, and the same with the new engine too.
And making sure the cam shaft and crank shaft are the correct measurement and have correct weight distribution. Also making sure the valves seal, hell I wouldn't be surprised if some of the bolts they took off weren't torqued properly.
I have a 1971 VW Bug project and ordered an engine built from a "reputable" shop here in Arizona. The engine was supposedly brand new, 0 miles. I didn't get to run it until a year after I purchased it. During this year gap, the shop closed "due to Covid". When I finally ran the engine, it blew up after about 15 minutes of running. Turns out the builder forgot to install the circlips on one of the pistons.
They're sending you an entire extra engine because of those issues? You get to keep the old one? Is that what they'd do for people without RUclips channels? Because that would be some wild customer service
i doubt they did for normal customers. normal customers probably put it into there cars, add a power adder like nos or turbo or super charger and then boom, all warranties are canceled and it was your fault. if you kept it NA and it dropped a rod it would most likely get inspected and or sent out or back at the owners expense to see what happened but then GM could really say anything if they wanted
Don't get your hopes up. Nobodies without media presence don't get preferential treatment like that because they can do way less PR damage than a youtube channel.

I worked for the detail department at a GM dealership and the amount of brand new vehicle's that come in with issues are astonishing! One in particular was a brand new Yukon, price tag was like $112k. As i was cleaning it for delivery i found a quarter sized hole in the lower portion of the passenger door. At the assembly plant they just threw on a door that was suppose to have a trim option, but never installed the trim so the holes for the trim were exposed to the elements. Should have seen the look on the salesman face when i told him about it. Customer had already been waiting 6 months for it, within an hour the customer was there and eventually said they didn't want the Yukon anymore.
Ive worked at GM and Hyundai. The GMs during PDI were usually not too bad. I think I had to align one once, my buddy had to fix a Camaro Conv top that wouldnt open, and some Tahoes that had the wrong modules in the seat. That was about it. Hyundai OTOH, that was a weekly ordeal finding one that didnt have a QC issue. Clamps not properly on hoses being a major one for awhile. Seen a few that had bent pins in harnesses, so whole CAN systems were down. Had a GV80 3.5 that they didnt drill the hole for the boost recirculation valve. That one was bad.

I’m a ford tech and I can confirm that brand new engines come in with problems all the time. Especially with timing. These new engines are built on production lines that the manufacturers keep going at full speed and these problems happen all the time. The problem is that the manufacturers found that it’s cheaper to warranty the new engines than slow down production for a better product. It just kind of sucks for us….
Yeah, my last car had one serious recall for the oil pump, due to the blades which had the potential to break off and end up starving the engine of oil. I imagine with American cars that are famous for being poor quality it's not entirely uncommon to see some with assembly mistakes 😅
I am a Mercedes tech and can confirm it is no different here. I was actually coming here to say the same thing. Manufactures have 2 options, build quick and just replace components that fail due to bad manufacturing with out blinking an eye, or take the time to build things properly but require insane in depth investigation when something does fail. Either option is frustrating for consumers but then again when has any person been happy to bring their car in for service.

My initial thought was they should throw it in the money pit Miata, but this makes more sense. Of course we don't watch Donut for sensible decision making so I'm voting for a swap.
What gets me is you KNOW that engine was gone over special since its a business deal with Donut. If they can't even get a good motor, what are you and I going to get?
What gets complicated for me is, trying to visualize & understand automatic transmissions with all the planetary gears & maze of directional fluid routes all the fluid goes in the worm trays & elsewhere to make it work & properly shift gears. Just the torque converter itself is sheer genius. Using literally nothing but fluid to connect the engine to the transmission. AKA no mechanical part/connection is used. Just fast spinning transmission fluid & centrifugal force.
Highly recommend buying a book or two, they are all basically the same for motors but will focus more on one or the other types depending on brand. For example, I got a John deere engines book and read through that, then rebuild my first straight 6 diesel no issues
Wow. If you guys had installed it, fired it up, and blown it up, you would have been screwed. This severely undermines the confidence you get when you buy a crate engine, let alone from the manufacturer. I realize that mistakes happen, but damn. I'm stunned.
Usually like 12 months and if you turbo it or supercharge it you better make sure they specifically stated the engine is meant for it or theyll tell you to pound sand@Blue_Flame_Raptor
There wasn't a mistake made....... There were MISTAKES made! That's unacceptable! Then add the fact THAT is what you get for 15 grand!! (There should have been 10 grand cash in the intake ports for that price!)
You guys should do a Replacement for Displacement series where you take a turbo engine and try to match power with the LSX. Then you could do a side by side comparison of the finished cars and a showdown. Really put to rest the age old argument.
I worked at Caterpiller for a year in one of their engine assembly factories Someone forgot a clip like that on one of the C18s. When it went to hot test the piston head came loose and chunks of the piston ended up blowing through the engine block. Ever since its been the main example for every new employee to teach that the smallest detail can lead to drastic effect
Love how they are giving you a new engine to clean up after their tracks, hoping you guys wouldn't release the footage. Well done for not holding back! Informed the public of a possible easy money tactic since race motors blow up all the time and they'd get away with the premature engine failure without being questioned. Now they have got to pull up their socks, at least momentarily.
I don't know about hoping they woudln't release the footage, they are just doing the best they can to make them "whole" without question. Giving you a new one doesn't leave any room for doubt. I guess you're hoping for them to announce that they failed over loudspeakers? It would be nice if they said something about it being unacceptable and how they're going to improve QC.
What if you take it apart, find out the clip is missing and the bearings are ruined, call GM and because you’re not a RUclips channel they tell you’re lying or you did it. I’d imagine that’s how it would go in 95% of cases
10:15 The crankshaft that drives the oil pump might be robust, but the oil pumps on those motors have been known to fail - or at least become anemic. Plus since they're internally mounted, maintenance, diagnosis and repair means your pulling the top half of the motor and the timing cover. Huge PITA when they used to be externally mounted and easily accessible. Your tear-down is showing that the reputation for being "reliable" or "bulletproof" lies mostly in the block and less in build quality and QA/QC...but of course we knew that 😉. Like the tear-downs, keep it up!
I don't think the oil pump was ever externally mounted. The old-school gen I and II small blocks had the oil pump mounted on the rearmost main cap, which was much more easily accessibly, I'll give you that. They do seem to have been more reliable than the gen III and IV LS pumps as well.
Here is a build for you and it’s one I’ve been wanting to do. Put the LSX in an Infiniti M45x S. You get a big body V8 Japanese luxury vehicle with all kinds of bells and whistles and an ATESSA AWD system. With some work you can make it an ATESSA ETS system and you will have one hell of a vehicle. Legendary LS engine married to the legendary ATESSA ETS in a Japanese big body… what could be better? It’s unique and hasn’t been done before. These cars fly right under the radar.
Got to keep the rep up! They have been known for flawed creates for well over 10 years! (I'm not a Chebby guy so I don't know the history more than that.... Wouldn't surprise me)
With the crank bearing being trashed you should really check that the crank is straight and have the line bore checked on the block and crank caps. Something's not happy in that set up the way it sits now.
It's modern GM quality. You're lucky if you make it 30k miles and it hasn't broken something. I've seen several brand new GMs with less than 5,000 miles break down, including entire engine and/or transmission replacements.
2002 GMC Sierra 1500 HD 6.0 4l80e 4x4, third transmission, 4th t case, 4th torque converter, endless u joints less than 200k, no can corners, no rockers, no bed sides, undercoated every year and grind and prime the rest after every winter, not a single button in the cap is readable, speedo doesn't work, fuel gauge is tuck at a half tank, battery gauge doesn't work, had to replace lifters twice, but I've never once had problems from the motor other than the tick, once this truck finally blows up or breaks in half I'll never have another Chevy made past the mid 90s pieces of shit every way you can think

I have my retired 2013 Tacoma sitting in my auxiliary building collecting dust. I also have an LS3 sitting not far from the Tacoma collecting dust. Yanked the engine from my buddies corvette after he was rear ended by a semi that had overheated his brakes and completely totaled the car. At least the engine was salvageable. It sat in my buddies shed for over 2 years before he sold it to me. He needed a few thousand bucks quick fast and in a hurry, so I got the engine for what I think was a steal. Its been sitting in my auxiliary building for well over a year now and Im really thinking about putting it in my ole 13 Tacoma.
@@lamp7746 I can give you a dozen on ebay that have more performance out of the box for 5k or less. 7.4L NA pushrod making 476hp is a joke. The real reason you buy this is forced induction setups. If you want an engine that can make 1000hp without internal parts then I think LSX is a very good option.
Thank you to GM to honor the repair and correct it with a proper block.(still check it) if I had a spare big block I would do a Donut Special and make a go kart out of it and SEND IT
Jerry and Jobe-y is the best pairing of hosts on Donut. No disrespect to any of the other hosts, but this is the best pair. They just work off each other so well.
What should you do with the next LSX? There are so many options! -LS swap the money pit miata LS swap Joe Webber's 300Z Drop it in the Catfish Camaro Build a custom motorcycle around it (it would probably have to be a three or four wheeler) Put it in a boat
Or as someone else said up there, keep that LSX as an emergency should anything happen to the Ranger. Which considering we're talking about: 1. A Baja Truck 2. The Donut Crew Anything can happen
it should never ever happen, where are the quality checks? They fixed it because they know they fucked up big time, and could have cost some one a lot. Its really not ok for a brand new 15k product, potentially dangerous to lives also in drag application
I'm guessing it is because they're Donut. GM knows they need to appear like they go above and beyond with mistakes to ensure that people are confident in continuing to buy LSX engines. It's because of the publicity.
You think they would do that for the average customer or do you think they would just blame the guy with no clout and screw him over? I'm thinking the later.
Great video! Shows the importance in a teardown even on a crate engine. Saved yourselves an arm and a leg trying to get it replaced after installing it and testing... For the new engine install it as a dyno engine to test out clutches by showing us how slipping the clutch effects the parts / the difference between the different stage clutches out there?
I think you guys should do a Super Syclone with the next LSX. - 94 S-10 Standard Cab/Bed or an SS variant. - Put X-Treme bodykit on it. - Add AWD system from Astro Van. - Add fat tires. - Go snatch souls.
The pushrod is not coming in contact with the camshaft. It sits in the lifter which is coming in contact pushing the pushrod. Y’all left that out in your description at the beginning of the video.
I have what I personally think is the best idea for the extra LSX. You can install it in my 1990 300zx! I recently had an engine mishap where the timing belt shredded while driving. So not only could you convert this Z to an LS, you could break down the original engine! I personally think this is an excellent idea and I'm all for it. I'd like the car back when it's running again though... hit me up for this once in a lifetime opportunity!
I just want to point out, since I've seen no other comments pointing it out, that a C8 corvette does NOT have an LS. Not sure who messed that up, but the last corvette with an LS came off the production line over a decade ago.
@@christianmcpheeters8638 the entire design is based on the L92 LS-based HD engine. It is the Gen V small block, a continuation of the Gen 3 and Gen 4 LS engines. Just cuz it has some fancy new letters doesn't make it all new.
@@americansmark except you're literally wrong. Completely different head design, different block design, direct injection, different crankshaft design, different rod lengths, literally not a single part of an LS or an LT is interchangeable. Not a single part. So how on earth are you saying it's the same architecture? It's not. The only common trait is that it's a pushrod V8 that General motors made.
I’m flabbergasted at the MAJOR issues with the build of this $15,000, engine and the guaranteed failure in a short time frame! The tech that “built” the bottom end, made GM look f*uckin terrible, the trash that was on the bearings was bad, but the missing circlip is CATASTROPHIC!! BUT WAIT, NEITHER FAILURE IS JUST $15k, I’ll cover that below….If the wrist pin clip wasn’t missing and they had just dropped the engine in like 99..5% of everyone does….there is NO WAY that GM would cover it they would say it was a tuner mistake or some other BS. The cost of the rebuild which could include, new rod(s), crankshaft, bearings, camshaft and possibly more or even chance of catastrophic failure, so at the absolute low end your at $18k+ for basic rebuild and machining and installation. NOW with the CIRCLIP you not only have CATASTROPHIC damage to engine, and yes I’m saying windowed block completely junked engine BUT you also normally damage/destroy the engine but also other accessories like your new headers, any type of oiling part like oil coolers and filters, cooling system, engine mounts, and possibly transmission and wiring…..so now your talking about $5k-$15k plus for everything that GM won’t be warrantying with the new $15k engine! Let alone the Labor costs and Downtime…. And the AVERAGE JOE isn’t going to be able to keep old engine AND get NEW ENGINE AND PARTS for damaged engine! All because someone wasn’t doing their job
I’m pretty sure the lsx is meant to handle insane amounts of boost, you should boost the new one and just keep upping the psi until it throws a rod into outer space
Nice job contacting GM with those issues. Those engines are supposed to be assembled by a single employee. They’re supposed to sign their name to every engine that goes out. It looks like the guy that built your engine must’ve been drunk. I’m glad to hear that GM took care of you. I hope you take the new engine apart also Just in case. Nice work!
We put a brand new LS3 crate into a s13 before and similar stuff happened. Called GM and sent some pictures in. We got a new replacement engine without too much back and forth BS though. The guy that I talked to named Ryan I think, he didn't sound surprise at all when I stated that there's rod knock in a 50 miles motor.
Absolutely amazing reaction from chevy that we aren’t talking about. Sure it’s probably partially because of the status you guys have but paying for everything and a whole new engine is like bravo from chevy.
Can you do a video where you compare buying a new vehicle with the top trim vs buying a lower trim level and specing it out the way you want? The new ford maverick comes to mind as all the trim levels are relatively cheap. I'm a truck guy so I was thinking an fx4 or tremor package vs just buying the bottom trim level and going with aftermarket suspension, interior, etc. Thanks, you guys are amazing!

If they had gone with a coyote they wouldn't even have to worry about this issue
GM dropped the ball on that assembly
Dropped it in the shaft, probably.
Apparently 15'000 isn't enough to ask for quality product these days.
Not surprised
What gets me is you KNOW that engine was gone over special since its a business deal with Donut.
If they can't even get a good motor, what are you and I going to get?
It was either built on a Monday or Friday. Or the boss said “why’s it taking so long to get this one out?? Wrap it up and send it out”
I love these engine teardown videos that you are doing. Honestly makes working on engines a little less intimidating
"It'll be fine"
_It being "fine"_
Glad you took apart this engine.
Watching Nolan become such an awesome host and always being kind, I think he deserves the LSX in the Imperial
he bought it for the 383, unlikely he will swap it out.
These engine teardowns are always my favorite. In depth but still simple for my dumb brain to understand
Agreed, I think they should take the new engine and do another teardown. Always inspect before you expect
What gets complicated for me is, trying to visualize & understand automatic transmissions with all the planetary gears & maze of directional fluid routes all the fluid goes in the worm trays & elsewhere to make it work & properly shift gears. Just the torque converter itself is sheer genius. Using literally nothing but fluid to connect the engine to the transmission. AKA no mechanical part/connection is used. Just fast spinning transmission fluid & centrifugal force.
Highly recommend buying a book or two, they are all basically the same for motors but will focus more on one or the other types depending on brand. For example, I got a John deere engines book and read through that, then rebuild my first straight 6 diesel no issues
Engines are very easy to understand
@MoloneLabe Obviously not if there's a huge mechanical business profiting off people that cannot understand it
That push rod hitting the floor sounded like the intro to Fire Starter....BOOM!!! (3:21)
Wow. If you guys had installed it, fired it up, and blown it up, you would have been screwed. This severely undermines the confidence you get when you buy a crate engine, let alone from the manufacturer. I realize that mistakes happen, but damn. I'm stunned.
It would still be covered under warranty but it would be wasted time for sure.
Crate engines usually have a short warranty
Usually like 12 months and if you turbo it or supercharge it you better make sure they specifically stated the engine is meant for it or theyll tell you to pound sand@Blue_Flame_Raptor
@@spadeykins9114 Good luck providing blown engine was manufacturer fault..
There wasn't a mistake made....... There were MISTAKES made!
That's unacceptable!
Then add the fact THAT is what you get for 15 grand!! (There should have been 10 grand cash in the intake ports for that price!)
You guys should do a Replacement for Displacement series where you take a turbo engine and try to match power with the LSX. Then you could do a side by side comparison of the finished cars and a showdown. Really put to rest the age old argument.
This is a fun idea
But there isn't a replacement. Slap that same turbo on the lsx and see what happens. XD
real mean turbo their ls
but that lsx454 is specifically made by Chevrolet Performance to be boosted
@@lucysmith4242 real men twincharge their LS.
I worked at Caterpiller for a year in one of their engine assembly factories
Someone forgot a clip like that on one of the C18s. When it went to hot test the piston head came loose and chunks of the piston ended up blowing through the engine block.
Ever since its been the main example for every new employee to teach that the smallest detail can lead to drastic effect
Love how they are giving you a new engine to clean up after their tracks, hoping you guys wouldn't release the footage. Well done for not holding back! Informed the public of a possible easy money tactic since race motors blow up all the time and they'd get away with the premature engine failure without being questioned. Now they have got to pull up their socks, at least momentarily.
I don't know about hoping they woudln't release the footage, they are just doing the best they can to make them "whole" without question. Giving you a new one doesn't leave any room for doubt. I guess you're hoping for them to announce that they failed over loudspeakers? It would be nice if they said something about it being unacceptable and how they're going to improve QC.
Good to know. Take apart your brand new thing and report the issues to the manufacturer to get a discount that pays for the inspection. Lets go.
What if you take it apart and it's perfect? Now the labor is on you.
When you buy a new engine, you expect the parts of that 15 thousand dollar v8 to all be in good shape lol
What if you take it apart, find out the clip is missing and the bearings are ruined, call GM and because you’re not a RUclips channel they tell you’re lying or you did it. I’d imagine that’s how it would go in 95% of cases
Well, take it apart and show it to 8 million people. GM did a PR move with the free engine.
@@mentat1341 It was more of a satirical statement to emphasize the absurdity that you cant even trust "new" products anymore.
You should definitely open up the second LSX too
10:15 The crankshaft that drives the oil pump might be robust, but the oil pumps on those motors have been known to fail - or at least become anemic. Plus since they're internally mounted, maintenance, diagnosis and repair means your pulling the top half of the motor and the timing cover. Huge PITA when they used to be externally mounted and easily accessible.
Your tear-down is showing that the reputation for being "reliable" or "bulletproof" lies mostly in the block and less in build quality and QA/QC...but of course we knew that 😉. Like the tear-downs, keep it up!
I don't think the oil pump was ever externally mounted. The old-school gen I and II small blocks had the oil pump mounted on the rearmost main cap, which was much more easily accessibly, I'll give you that. They do seem to have been more reliable than the gen III and IV LS pumps as well.
Here is a build for you and it’s one I’ve been wanting to do.
Put the LSX in an Infiniti M45x S. You get a big body V8 Japanese luxury vehicle with all kinds of bells and whistles and an ATESSA AWD system. With some work you can make it an ATESSA ETS system and you will have one hell of a vehicle. Legendary LS engine married to the legendary ATESSA ETS in a Japanese big body… what could be better?
It’s unique and hasn’t been done before. These cars fly right under the radar.
Are you slow? Definitely wouldn't work without major ecu problems
@@bitchesihate Are you? What major swap doesn’t encounter major electrical issues?
No shit it’s gonna be hard.
GM sending out bad parts??? WHAT A SHOCK!
Got to keep the rep up!
They have been known for flawed creates for well over 10 years! (I'm not a Chebby guy so I don't know the history more than that.... Wouldn't surprise me)
unfortunately every brand sends out bad crate motors. it depends on your luck really
I had to replace knock sensors in my 5.3 LS twice do to bad GM sensors. That was cool.
With the crank bearing being trashed you should really check that the crank is straight and have the line bore checked on the block and crank caps. Something's not happy in that set up the way it sits now.
More likely a chip in the oil hole.
It's modern GM quality. You're lucky if you make it 30k miles and it hasn't broken something. I've seen several brand new GMs with less than 5,000 miles break down, including entire engine and/or transmission replacements.
2002 GMC Sierra 1500 HD 6.0 4l80e 4x4, third transmission, 4th t case, 4th torque converter, endless u joints less than 200k, no can corners, no rockers, no bed sides, undercoated every year and grind and prime the rest after every winter, not a single button in the cap is readable, speedo doesn't work, fuel gauge is tuck at a half tank, battery gauge doesn't work, had to replace lifters twice, but I've never once had problems from the motor other than the tick, once this truck finally blows up or breaks in half I'll never have another Chevy made past the mid 90s pieces of shit every way you can think
@@justiceabrams5812 holy crap dude i think that truck has already blown up, I got a 90's crv with 160k and have only replaced the starter and the little clock.
Modern anything tbh

@2:19 it is an overhead Valve engine, Jerry. YEAH, JERRY!
That was the best illustration and explanation of push rods i've ever seen! I searched about it for hours and understood it better in a few minutes kudos to donut media
Except the part where they said the push rods run on the camshaft completely forgot about lifters

Engine assembled Friday at 4PM
I have my retired 2013 Tacoma sitting in my auxiliary building collecting dust. I also have an LS3 sitting not far from the Tacoma collecting dust. Yanked the engine from my buddies corvette after he was rear ended by a semi that had overheated his brakes and completely totaled the car. At least the engine was salvageable. It sat in my buddies shed for over 2 years before he sold it to me. He needed a few thousand bucks quick fast and in a hurry, so I got the engine for what I think was a steal. Its been sitting in my auxiliary building for well over a year now and Im really thinking about putting it in my ole 13 Tacoma.
What’s inside a 15,00 dollar motor? About 3500 dollar in parts 😂
Ok genius make an engine for 15,000 that’ll outperform that.
Totally how design, manufacturing and assembly works.
As well as some parts that are engineered differently to typical LS engines for greater strength. Hence why it’s an LSX.
Find me an LSX454 for 3500💀
@@lamp7746 I can give you a dozen on ebay that have more performance out of the box for 5k or less. 7.4L NA pushrod making 476hp is a joke. The real reason you buy this is forced induction setups. If you want an engine that can make 1000hp without internal parts then I think LSX is a very good option.
Thank you to GM to honor the repair and correct it with a proper block.(still check it) if I had a spare big block I would do a Donut Special and make a go kart out of it and SEND IT
I was thinking Time Attack Catfish Camaro, but yeah a single seat Kart-O-Death would be pretty insane!
Jerry and Jobe-y is the best pairing of hosts on Donut. No disrespect to any of the other hosts, but this is the best pair. They just work off each other so well.
0:39 These two working together is great to see!
9:52. make one of those toilet wrx's reliable, and put the LS in there.
LSX CHANG LI
I just lost my confidence in GM. They used to be reliable.
Here I was just today thinking "I haven't heard anything about that Ranger in a minute, I wonder how the build is coming along?" And here we are.
What should you do with the next LSX? There are so many options!
-LS swap the money pit miata
LS swap Joe Webber's 300Z
Drop it in the Catfish Camaro
Build a custom motorcycle around it (it would probably have to be a three or four wheeler)
Put it in a boat
How about the drift BMW?
Or as someone else said up there, keep that LSX as an emergency should anything happen to the Ranger.
Which considering we're talking about:
1. A Baja Truck
2. The Donut Crew
Anything can happen
They should put it in the drift BMW.
@@justaguywithcrx good idea
@@peixeserra9116 good point
My buddy got a brand new crate engine for his 04 GTO, his alao had deep scratches / marks in several areas of the interior of the engine.
I just got a 5.3 LS for my 74’ Nova and seeing donut do a new lsx got me real happy
9:50 gm coming in clutch hopefully it's not bc of your size but be cause you communicated truthfully the issue and were dealt with properly and fairly
Yeah i wonder if the same thing happened to me would i get a free engine too or only get offered repairs
it should never ever happen, where are the quality checks? They fixed it because they know they fucked up big time, and could have cost some one a lot. Its really not ok for a brand new 15k product, potentially dangerous to lives also in drag application
It is pretty embarrassing.
Is GMs engine manufacturing as badly organized as Boeing?
I'm guessing it is because they're Donut. GM knows they need to appear like they go above and beyond with mistakes to ensure that people are confident in continuing to buy LSX engines. It's because of the publicity.
It’s 1000% due to the channels size
OMG! They're talking about me 🤩🤩🤩
everyone has heard of you!
Thank you for keeping our engines buoyant.
@@Lydomina Not a problem, just doing my job
Fairly certain you guys haven’t used that LSX… I think you should help me throw it into my 03 outback wagon😎 9:55
QC guy must've taken off the day that engine was built lol. Good on GM for making it right
You think they would do that for the average customer or do you think they would just blame the guy with no clout and screw him over? I'm thinking the later.
8:17 i dont know where his accent is from. But i do know, when you hear a guy who sounds like that say "bro" like that: its never good😂
Could be Greek. The name at least sounds Greek.
Amazing video as always boys!
5:33 That engine got heart ❤😂
5:47
This is pure and unadulterated Donut right here. The pause just for the comedic timing is what I'm here for. What the fuck is an LS3
Do an exomotive exocet build with the LSX, that would be right up Donut's alley
You guys were cursed by the Ford Gods, for the sin of dropping in a Chevy engine.
Needed to disassemble and reassemble a old diesel I4. Looks fairly simillar but yet totally different, pretty fun to see actually!
An extra lsx. Sounds like it's time for a monster Miata.
Great video! Shows the importance in a teardown even on a crate engine.
Saved yourselves an arm and a leg trying to get it replaced after installing it and testing...
For the new engine install it as a dyno engine to test out clutches by showing us how slipping the clutch effects the parts / the difference between the different stage clutches out there?
Now that's a brilliant idea, I too would like to see this. I vote for this!
I think you guys should do a Super Syclone with the next LSX.
- 94 S-10 Standard Cab/Bed or an SS variant.
- Put X-Treme bodykit on it.
- Add AWD system from Astro Van.
- Add fat tires.
- Go snatch souls.
and then give it to me 🤣 I want a Syclone so bad!!! lol
These two together is the last of old donut, dont ever take this away from us.
Toyota Previa for the new LSX. Great video 👍🏻
Visuals: Donut Dudes tearing down engine
Audio: Rave scene in Wesley Daywalker movie
“Think of how big a hotdog this could hold” honestly a restaurant in an old gas station who’s baskets are head covers would be fucking sick
Bonus LSX should go in something small and/or dumb, Miata, Pinto, gremlin, triumph, or mid engine minivans can also be dope.
FINNNALLLY IVE BEEN WAITING FOR THIS FOR SOOO LONG🔥🔥🔥
You see all that shit going on in there?
Same!
Never been here this early! Maybe should swap an lsx into my car... Or maybe just fix the lifter tick in the current motor...
Fix the lifters! While you’re in there might as well port the heads and do a cam too 😉
@@JGMochey "Well, since it's apart..." 🤣🤣
@@tommyw.7850might as well and since you’re already there just replace the injectors they can get a little clogged
@@tommyw.7850 that’s always been my excuse! Wife hasn’t found a flaw with that thinking yet!
Who cares that you are early…
The pushrod is not coming in contact with the camshaft. It sits in the lifter which is coming in contact pushing the pushrod. Y’all left that out in your description at the beginning of the video.
Its donut quality work right there
It's called "engagement farming"
They're keeping it simple for the normies. Otherwise we'd have an hour-long video.
0:44 where is that moan from ??? the original one ?
I have what I personally think is the best idea for the extra LSX. You can install it in my 1990 300zx! I recently had an engine mishap where the timing belt shredded while driving. So not only could you convert this Z to an LS, you could break down the original engine! I personally think this is an excellent idea and I'm all for it. I'd like the car back when it's running again though... hit me up for this once in a lifetime opportunity!
Hey, you know what? The engine in my Scirocco has died as well, and I want a new engine. Can I have this $15,000 engine in my car for free too please?
@@AN2Felllla exactly! Do theirs too! That's like what, 4 videos now? RUclips is easy!

Valid point
Damn son
I just want to point out, since I've seen no other comments pointing it out, that a C8 corvette does NOT have an LS. Not sure who messed that up, but the last corvette with an LS came off the production line over a decade ago.
The LT is still an LS-based engine. It's the same architecture, just modernized.
@@americansmark no it isn't, completely different everything. That's like saying an LS is based on a gen 1 small block. No, it sure isn't.
@@christianmcpheeters8638 the entire design is based on the L92 LS-based HD engine. It is the Gen V small block, a continuation of the Gen 3 and Gen 4 LS engines.
Just cuz it has some fancy new letters doesn't make it all new.
@@americansmark except you're literally wrong. Completely different head design, different block design, direct injection, different crankshaft design, different rod lengths, literally not a single part of an LS or an LT is interchangeable. Not a single part. So how on earth are you saying it's the same architecture? It's not. The only common trait is that it's a pushrod V8 that General motors made.
I’m flabbergasted at the MAJOR issues with the build of this $15,000, engine and the guaranteed failure in a short time frame! The tech that “built” the bottom end, made GM look f*uckin terrible, the trash that was on the bearings was bad, but the missing circlip is CATASTROPHIC!! BUT WAIT, NEITHER FAILURE IS JUST $15k, I’ll cover that below….If the wrist pin clip wasn’t missing and they had just dropped the engine in like 99..5% of everyone does….there is NO WAY that GM would cover it they would say it was a tuner mistake or some other BS. The cost of the rebuild which could include, new rod(s), crankshaft, bearings, camshaft and possibly more or even chance of catastrophic failure, so at the absolute low end your at $18k+ for basic rebuild and machining and installation. NOW with the CIRCLIP you not only have CATASTROPHIC damage to engine, and yes I’m saying windowed block completely junked engine BUT you also normally damage/destroy the engine but also other accessories like your new headers, any type of oiling part like oil coolers and filters, cooling system, engine mounts, and possibly transmission and wiring…..so now your talking about $5k-$15k plus for everything that GM won’t be warrantying with the new $15k engine! Let alone the Labor costs and Downtime…. And the AVERAGE JOE isn’t going to be able to keep old engine AND get NEW ENGINE AND PARTS for damaged engine! All because someone wasn’t doing their job
GM doing GM things.
put the new motor either in the Drift BMW, Miata or the rb swapped Silvia
I’m pretty sure the lsx is meant to handle insane amounts of boost, you should boost the new one and just keep upping the psi until it throws a rod into outer space
The new LS goes in the Miata. No questions asked.
@donut you gotta put the LSX in the money pit miata 🔥🔥🔥🔥
Definitely open up the second one they send out, but I think it would be super cool to put it in the Miata!!
LSX in the yellow donut van, after taking it apart to verify there are no abnormalities.
1:46 where are the hydraulic rollers? Pushrods aren’t riding on the cam lobes. Db
Nice job contacting GM with those issues. Those engines are supposed to be assembled by a single employee. They’re supposed to sign their name to every engine that goes out. It looks like the guy that built your engine must’ve been drunk. I’m glad to hear that GM took care of you. I hope you take the new engine apart also Just in case. Nice work!
We put a brand new LS3 crate into a s13 before and similar stuff happened. Called GM and sent some pictures in. We got a new replacement engine without too much back and forth BS though. The guy that I talked to named Ryan I think, he didn't sound surprise at all when I stated that there's rod knock in a 50 miles motor.
Extra LSX??
TWIN engine vehicle!
this has been my favourite ad segway by far
Absolutely amazing reaction from chevy that we aren’t talking about. Sure it’s probably partially because of the status you guys have but paying for everything and a whole new engine is like bravo from chevy.
Can you do a video where you compare buying a new vehicle with the top trim vs buying a lower trim level and specing it out the way you want? The new ford maverick comes to mind as all the trim levels are relatively cheap. I'm a truck guy so I was thinking an fx4 or tremor package vs just buying the bottom trim level and going with aftermarket suspension, interior, etc. Thanks, you guys are amazing!
So much for "I think they go it figured out by now" 3:03
Props for the customer service! But I mean that's crazy. There's a reason a sold my chevy and bought a taco!
Glad it happened to you guys and not a random person to findout the hard way
Doing your part in holding car manufacturers accountable. Thanks for that!
