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.

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

[@CRneu]

idk this is pretty bad on GMs part. Bad bearings and forgetting something on the wrist pin are pretty huge mistakes. I think the way Donut was able to get a new motor out of it is because they properly documented the mistakes that GM made so there is basically zero wiggle room for GM.

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.

[@jacobturner9073]

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….

[@cosmic7234]

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 😅

[@TwinShards]

It's crazy there is not even quality control for a buffed performance engine.

[@maximiliankehler2547]

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.

[@upinarms79]

It's pretty much that way in any corporate-ran workplace these days. If they have to choose between quantity and quality, they'll always choose quantity, especially if it means cutting the least bit of profit. I mean, how else are the CEOs going to afford their 3rd vacation home on a private island?

[@lHlEIDLEBAUGH]

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.

Got a lawyer and GM owned up about those parts all having issues in the 6.2L LS specifically. Got a good chunk of money back but now we have an SUV that we can’t in good conscience sell to someone.

Now they have got to pull up their socks, at least momentarily.

[@QuinnShaw]

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.

[@michaelbrinks8089]

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.

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.

[@jaclynvassallo7604]

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!

[@gabrielulibarri9950]

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.

[@lemon19mmm]

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.

[@RevZilla]

Amazing video as always boys!

[@agentsleepyhead]

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

[@josephmatuszak3855]

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.

[@Chache1527]

and then give it to me 🤣 I want a Syclone so bad!!! lol

[@masonholland9909]

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

[@adrienross8458]

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?

[@sergiojurado8887]

Now that's a brilliant idea, I too would like to see this. I vote for this!

[@lucasrose2889]

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!

[@AN2Felllla]

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?

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

[@RVMD95]

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!

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.

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

[@christianmcpheeters8638]

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.

[@americansmark]

The LT is still an LS-based engine. It's the same architecture, just modernized.

[@christianmcpheeters8638]

@@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.

[@americansmark]

@@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.

[@christianmcpheeters8638]

@@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.
