LSX Engine: How It Works

We tear apart a brand new Chevrolet LSX V8 engine to see what makes it so robust, with some surprises along the way.

Donut = We like cars, and we like making videos about cars. Hopefully our videos make you like cars too.

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."

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.

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

[kevinde]

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"

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.

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

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.

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 YouTube channels? Because that would be some wild customer service

[MachoMandem]

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.

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

[stardustjustlikeyou]

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

[ExCordeEnt]

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

[wesleymuller]

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

[MikeHarris]

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

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

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.

[JendaHrbac]

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

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.
