When the new engine comes in, you should do another recorded teardown to see if there are any issues with it.

"They didn't even test fire it?" "They know what they're doing by now." mhm aged like milk

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.

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.

That's brutal quality control. A regular consumer isn't getting a free replacement engine.

Cripes, you bought the Friday 4:30pm end of shift engine. "Beers ain't getting any colder...fuck it, ship it"

That's CRAZY. Those aren't just "issues", this engine would destroy itself real quick if you just decided to run it without checking.

The corvette and camaro at the beginning don't use LS engines, they use LT engines. Might seem like quibbling, but there's almost no interchangeable parts between the two

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 UKposts channels? Because that would be some wild customer service

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.

Holy hell. GM better be watching this! Missing wrist pin clip and bearing chewed up, thats insane on a 15k drop in package.

This channel probably saved my life. Over the past 8 or so months I lost my job, my girlfriend of five years is moving, I became depressed and my relationship with my family became strained or completely broken with some members, then as a final fuck you from life turns out I have colon cancer. I had zero energy to do anything. I had completely given up. Didn’t even eat for days. Or get out of bed. Then one day my cousin gifted me his old 07 Charger out of nowhere. It’s completely fucked. Electrical problems up the ass won’t even start but I’m slowly working on it. Then one day it was somehow okay enough now to go struggling around on solitary midnight rides around town… then suddenly my forgotten childhood passion of cars was rekindled. Next I found this channel donut and I was suddenly back to my childhood days making models or playing with my dozens of hot wheels all with customizations I crudely but passionately made using clay, poster paint, pipe cleaners, parts from other hot wheels, LEGO, anything I could get my hands on. I remembered playing fast and the furious with my toys and all the storylines and narratives and the made up jargon I used to sound legit. I remembered how cars were the beginning of my interests in engineering, robotics, chemistry, and technology. I kept watching donut videos and having so much fun I was able to get out of bed to go see if I can work on the Charger, make plans for it, try to drive her or simply just be an actual human again. I’m still low key fucked and so is the Charger. lol but for the first time in long time I have hopes and dreams and I’m finding meaning and purpose in my life. Even if it’s in something as simple as remembering to eat or getting out of bed. Or something more grand like my dream of having my Charger running and looking like a BEAST. I’m living life again. I have energy and motivation again. So from the bottom of my heart. Thank you.

gotta love the kind of customer service you get when you are a social media company

do an engine teardown on the next LSX too to see if you can get a third

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.

GM dropped the ball on that assembly

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.

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 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.

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….

That push rod hitting the floor sounded like the intro to Fire Starter....BOOM!!! (3:21)

I love these engine teardown videos that you are doing. Honestly makes working on engines a little less intimidating

Honestly just keeping the new LSX on standby for parts that will break on the ranger is probably be the wisest and most financially beneficial move

Options for the LSX: 1. Nolan's patina princess 2. Since it was free....Low Z 3. My 2018 Sonata?

@2:19 it is an overhead Valve engine, Jerry. YEAH, JERRY!

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.

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.

These engine teardowns are always my favorite. In depth but still simple for my dumb brain to understand

0:39 These two working together is great to see!

Needed to disassemble and reassemble a old diesel I4. Looks fairly simillar but yet totally different, pretty fun to see actually!

Jeremiah and Zach together always makes for a fun episode.

What’s inside a 15,00 dollar motor? About 3500 dollar in parts 😂

Got a 1990 GMC single cab step bed Looking to do protoringstyle that might be a good idea for the new LSX.

I absolutely love the diversity in your videos! Great channel

"It'll be fine" _It being "fine"_ Glad you took apart this engine.

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.

These two together is the last of old donut, dont ever take this away from us.

Extra LSX?? TWIN engine vehicle!

Watching Nolan become such an awesome host and always being kind, I think he deserves the LSX in the Imperial

GM sending out bad parts??? WHAT A SHOCK!

Bonus LSX should go in something small and/or dumb, Miata, Pinto, gremlin, triumph, or mid engine minivans can also be dope.

I love these videos, I'd love it even more if you put that extra LSX motor in a peel 50.

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

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.

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!

Definitely open up the second one they send out, but I think it would be super cool to put it in the Miata!!

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!

You should definitely open up the second LSX too

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!

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.

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.

Engine assembled Friday at 4PM

Also, Is there no assembly lube on those rod bearings? If there is, should be no issues turning it over a few times by hand. How else would you do something like install torque converter bolts or something like that?

Who needs a mid engine car when you could have an off-road truck with an LSX the front axle and an LSX on the rear axle!

been waiting on thi truck build so long meen.. finally some updates.. am tryna make a replica

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.

The 2000s Hacking music in the background hits hard

I did a replacement engine on a dodge Durango and the new engine had low oil pressure so they sent a replacement and that one had low oil pressure then the third worked right and to my knowledge had no problems

this has been my favourite ad segway by far

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

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😂

I would love to see the other engine inside the engine bay of a japanese kei car equipped with 4wd or awd.

At least u guys took it apart to know before so nothing bad happened

9:52. make one of those toilet wrx's reliable, and put the LS in there.

OMG! They're talking about me 🤩🤩🤩

Inspection of the engine before racing is key .. And is a good way to get backup engines for the race truck. 2ND..The second engine that is sent film another inspection tare down if happens again ask cor the repairs cost and have them pay thl for the 3rd engine. Repeat the steps till you get perfect engine or they refuse to send more engines to keep you happy.

I'm looking for an LSX I may have a suggestion as to what you can do with it! 😂😅😢 That's actually pretty awesome that they would send you a whole new engine plus pay to fix the original. Good on GM for that, but kind of scary to think that could have just gone in a car. Lucky you guys decided to take it apart

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

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

Yall should do some 2.2 ecotec stuff. it is the ls of gm 4 cylinders.

That’s how you know there’s major markup on the engines when they’re okay just GIVING you a $15k engine and repairing the “old” one.

QC guy must've taken off the day that engine was built lol. Good on GM for making it right

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.

Glad it happened to you guys and not a random person to findout the hard way

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

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

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.

Next Season of Hi-Low be Drag-Strip cars please! And hold on to the new crate engine until then!

great vid boys keep it up

You guys were cursed by the Ford Gods, for the sin of dropping in a Chevy engine.

I just got a 5.3 LS for my 74’ Nova and seeing donut do a new lsx got me real happy

I believe you guys have a tube bender. Build a cross cart for the Miata engine and do a monster miata

I think the second LSX should go into a g37 coupe and take the all wheel drive system from the g35x and modify it to fit the coupe and twin turbo it. Make a super car killer. Like a mini GTR with a V8

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.

An extra lsx. Sounds like it's time for a monster Miata.

I think you should install the other LS X in my black on black 1979 Trans Am. You can have the low mileage, hot rodded 454 that’s in it now to put in some Japanese import one of you guys undoubtedly own.

Was it before or after you out the engine together that you guys did all that firewall grinding and cutting right at the throttle body opening on the ranger? Just wondering at what point you guys also dusted the engine?

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?

The new LS goes in the Miata. No questions asked.

but that 2nd engine in a 1st gen tacoma or a 1st - 3rd gen 4runner 4x4 it would be crazy🤘🏽

Putting it in a Miata, basically a V8 Miata MX5 build, would be nice.

Amazing video as always boys!

That's a 454 in American cubic inches big block. And honestly the issues in the engine aren't that rare. Obviously it was 4,55 on a Friday at the factory. I've seen some brand knew Volvo diesel engines with similar issues straight outa the crate

heres a thought take apart the second lsx and see if it has anything misssing and if there is than they will give you another engine and repeat

I just love your videos, been watching donut since I was 10. Love from Bangladesh. Keep up the great work and keep inspiring us more more. Love your work.

Do an exomotive exocet build with the LSX, that would be right up Donut's alley

Dual V8 car (Mad Max -it) ... It has to be something crazy... Of course you need to open 2nd one also 🤫😉🤣

I have been stocked, to watching your videos. Just love your content. Would you be willing to create a video about expensive, cheap, innovative and ugly mods that I can put to my m340i?

Never been here this early! Maybe should swap an lsx into my car... Or maybe just fix the lifter tick in the current motor...

Looks amazing
