Customer told me this would be the third engine that did this in this car! He said it is time to send it to the crusher. Game over for this fine GM product.

Now that sad 2 engine did that
wow, 3 strikes & you're out Caddy
He's changing the oil??? 😮
Nothing to see here. folks, just another fine GM product headed to your local crusher and then to China 🥴. We know how to build engines that last. Why are we still dealing with this type of situation?
Wow. The worst part of being a mechanic is giving the bad news. So disappointing.
For this old backyard mechanic, it is always fun to watch a true technician at work that knows what he is doing. No
verbal gobblygook, just straight talk. Thank you for the videos.
Depstech endoscope，perfect，
We have a piston manufacturer in my town, that used to be our largest employer. They make pistons for GM, Toyota, Nissan, Ford and many others. They have in the last 10 years or so, been moving all of their production to Mexico. They were supposed to have moved everything and close our plant by the end of last year. They have not closed our plant yet and sound like they might be bring some of the production back from Mexico. Apparently, Mexican quality isn't as great as they thought it would be.
I know of a certain Japanese company that moved some of their production to Mexico. It is the LOWEST QUALITY of employee you can imagine. They use illiterate people in rural, drug infested, regions to do the work. The definition of IDGAF. Gang violence in the plant is so bad they have armed security throughout. From the outside it looks more like a prison than a manufacturing facility. They literally have guard towers - you can see the razor wire fencing and guard towers from Google maps. They had to fly a US executive out of there in an emergency because they were witness to a gang shooting at a restaurant - right in front of them as they ate. They had to go straight to an airport, onto a private jet, and leave everything behind in like 30 minutes. It's not America by a longshot. Point being, do not purchase a vehicle assembled in Mexico, no matter the brand.
No way José! 😁
Yeah now we have millions of the goofs in America that don't know anything
@@gatolibero8329companies want to make things in Mexico because they pay the employees close to nothing and want mass production for profit. Can't blame employees that get paid way below minimum wage. If manufacturers choose to get things done in Mexico for cheaper labor they are to blame and not the people manufacturing the parts. It all comes down to greed.
@@frenchonion4595They cut their prison costs by 100% thanks to Joe Biden.
Unbelievable that there are ‘shops’ who still replace coils, plugs etc. when the engine sounds like this when cranking.. Talking about incompetence.. Greetings from across the pond!🇳🇱
That lope during cranking is a dead giveaway.
Lack of desire to grow as a tech!!
Mechanics have done this type of crap for years. It's about the money!
🇳🇱
As someone who works on their own stuff but isnt a professional by any means and has never heard that kinda crank my first move would have been a coil.... so may not have been a professional who did it.
Now we need that engine sent over to I Do Cars for a Saturday night teardown LOL.
Eric's a cool dude 😎
It needs more crank case viewing ports; probably not a bad core for other bits though - I'm sure there will be a good water pump for him to resell.
Very, very cultured comments here
@@cheeseburgerbeefcake 🤣🤣🤣
That was one of the piston set we manufacture at the Federal-Mogul facility (now Teneco) located in South Bend Indiana up until about three years ago when all the piston manufacturing was moved to Mexico. When I started there 35 years ago one full production line was dedicated just to Cadillac. The last major project I worked on was the GEN V engines which included 5.3 L, 4.3 L and the 6.2 L. Take a look at the crown so those Pistons that are completely machine no casting surface left and we did it with only three tools and we had to achieve a cycle time of 12 seconds per part. We were able to do that by using a dual spindle machine and using two of them.
I was more than a little surprised to see casting on those pistons. Which is good from a casting quality perspective... but not something I have seen in piston design.
Tenneco went to Mexico/China on the Struts/Shocks that used to be made in Kettering Ohio. They are a horrible company.
Mr. Wiggles gives an excellent picture!
Yeah, that thing is top notch! The picture quality is excellent, and the lighting is just right, and you can flip the camera to look upwards? They did a good job on that thing!
Would also be great to use for checking wall studs in houses for insect damage and insulation fill.
I just bought a Mr Wiggles after watching this.
I bought a 2013 f350 super duty diesel a few years back. When it stopped starting I took it in for repair to a guy near me who only works on ford diesel trucks. I wondered at the time how a mechanic could be so focused on such a narrow product line and still make a profit. 5 years and $10,000 later, I now know why.
I know a one man shop that does almost exclusively Subaru head gaskets.
Ya diesels went down the tubes around 2005 when the govt put all.these regulations on diesel engines.
We have a shop in Denver area that does nothing but moonroof motor replacement on Ford pickups
😂 All of the diesel specialists make coin. Doesn't matter which brand either but Ford seems to have cornered the market.
Fix Or Repair Daly. Found On Road Dead. F'ing Old Rebuilt Dodge. F-O-R-D Ha!
After watching Mr. O's diagnostic skill I have come to the conclusion that if he can do it...umm no I would not even try. Excellent diagnostic skills!
if he can do it i can do it , with his tool sets 😂
Legend has it Mr.O has a tool to make a car disappear if it's being ridiculous.
@@attilakohbor3360 and his skill set?
This is too easy of a diag. You can hear the engine when cracking; next to tell the customer if it is an upper of lower end of the engine. Either way will be costly and recommend a new engine instead of rebuilding which is usually more expensive.
@@Sneakdisscommentbelow what are you implying?
Owning a Cadillac with a turbo outside of warranty is a dangerous proposition.
Owning an Out of Warranty Caddy, is a Dangerous Proposition, Period
Same with Euro trash ones
owning any gm product is a dangerous proposition period.
Just about EVERY, manufacturer today with a turbo and direct injection WILL fail
Unless you have tools and median level skills
"Put the pedal to the plastic " always cracks me up !
I’m from Hawaii and just love when Eric says that the next repair is the “crusher” from rust.
Friends of mine in their eighties driving to church 35 mph Blvd. had this same engine blow up. One dropped valve/cylinder destroyed their engine. Cadillac replaced the engine at no cost. "Cadillac, Cadillac, wish I had my money back."
For an experienced mechanic to say "that is the worst smell", that's saying something...must be something really special!
Pulling head bolts or main cap bolts on an overheated engine is way worse in my opinion
Old Supercharger Oil or burnt Diff/Transfer Case Oil. Absolutely horrid.
@@kevinganus4468 Yep. Burnt hypoid gear oil has me almost gagging.
Thats just Cadillac luxury. Running on 3 cylinders to save fuel. Silly Eric!
Just the modern version of Northstar.
@@Asrock73 northstar pulled the studs out of the block. these just stretch the studs instead. too much power for GM to cheap out on fasteners. a $400 set of ARP studs is mandatory for this engine, even at stock.
It's the modern V8-6-4. Just doing it's thing.
That's a pretty standard piston crown for a modern DI engine. That odd depression is meant to concentrate the fuel for the best burn. Slightly reminds me of Honda's old CVCC system with their aux intake valve pre-combustion chamber.
They can change the injector timing and pressure depending on rpms and engine temperature. The depression is used during idle speed. There is a Honda video floating around that explains direct injection very well. Nobody at GM training ever explained to us techs how the system works... go figure.
I bought a new 75 Honda Civic CVCC. The gas mileage was not impressive at all. About the best I got with it was 30 mpg. I loved that little car but reliable, it was NOT.
@@williamwhite9767I recall Honda's goal with the CVCC was meeting emissions and no catalytic converter, so you could run regular leaded fuel that cost less. This was before leaded fuel was eventually banned.
Similar to Honda, except the Honda would go 200,000 with just valve adjustments. The state of the art for IC is now "clever, complex and unreliable". What a shame.
@@scrappy7571 Yep, my 75 didn't have a cat but most cars got one in 74 I believe.
You nailed that turbo sound 😂
Pssstsssp-sttststs-psshhhhh 💨

I love watching you diagnose. You *listen*, and you follow the clues, and you *know* how to interpret the data. That's some craft, and I love it.
I have a Cadillac CTS 2.0T. When I first bought it I made the decision to use synthetic oil and premium fuel. So far I put a couple of cam solenoids and spark plugs in it. 130,000 miles now. Love your videos
My ATS has the 2.0T in it and going on 125k and had zero issues except maintenance. Same with using synthetic oil changed every 4k and premium fuel. I also had a walnut she'll carbon clean out done at 100k.
And this info is in the owners manual. Premium oil AND fuel. Good on you for treating them right.
@@christopherharris3229 5000 miles maximum oil changes are key to keeping these modern GM engine alive actually not just GM all modern engines really
@@lieutenantdan8170 Here in Australia we do a 5000 klms oil change (about 3000 mls)I always use synthetic oil.
The problem with these high output low displacement turbo engines is that people don't treat them as such, a small block chevy may have less horsepower but you could run one on varnish and dino oil without catastrophic failure. You gotta use premium on turbo engines, knocking and pinging usuallyresults in cracked and melted pistons. I do wonder if pinging was the cause of the issues on these enhine or if its just a design flaw, they are a funny piston design after all.
That camera is amazing! Thanks for sharing Eric!
Mr Wiggle 😂
still here and listening, you are an amazing automotive Technician
Mr Wiggles is quickly becoming my favorite SMA tool.
I was thinking about buying this same model of car a few weeks ago. Now I am very glad I changed my mind. Thank you!
Reminds me of an Opel GT in college that was referred to me as I became known as the car guy in the dorm. It was running rough. I opened the oil fill cap and a hurricane force wind came out. I was surprised how obvious it was and I had to tell the unfortunate owner that it was done.
Hey, Eric's sniffer is back to normal operation, glad the Rona wasn't permanent.
😂 u right. Glad we got sir sniffy again.
I remember smelling rotten meat all the time for a couple of months. It was lovely.
When I got Corona I only lost my smell for like 2 weeks and it came back

Wow that’s crazy about motor being replaced 3 times
Crazy to think Cadillac use to have a 500 and here we have a 123 cubic inch engine.
Can you still get a V8 in a cadillac?
@@eltonyancey6426CT5 V Blackwing and Escalade, at least.
Caddy made the 500 back when Ford made the Pinto. Now the caddy has a Pinto sized engine.
🤣🤣🤣🤣🤣🤣
Sign of the times even Cadillac are feeling the pinch.
@@eltonyancey6426Maybe in the trunk/hatch.
Too bad my dad is no longer with us because he knew just what to do with a car like this. Dump a can of STP in it and take it to the dealership after the service department is closed and when it’s dark outside. Tell the salesman that with the right car on the lot and a good trade deal he’ll move a vehicle before the store closes. No harm no foul. After all, the trade is probably going to the auction anyway.
Lols. Might have worked back in the day prior to OBD, but guessing the used car lot salesman will always have a scan tool and know how to check for those DTCs, and signs of whether it’s been reset recently mean you are trying to pull one.
@@zerog2000 you would be surprised
They fuck you so bad on trades that the probably hardly give a fuck. And they're going to drive it anyhow. Whoever does the buy bid won't be a booger picking salesperson, so even if they bid before a mechanic can look at it, they will know its got a dead hole. The bid guy is going to price assuming dead motor.
Hellz yes boys, SMA droppin’ a video on a Friday afternoon.
It may seem mundane when you see it every day, but it is very educational and Fantastic Content !!!! Thank You Eric !!!
I don't work on cars, but I'm enjoying this video (SMA fan). From now on, I'm gonna call a screwdriver a "piston indicator tool" no matter what I'm using it for.
A flat head screw driver is usually anything but a screw driver.
For many it’s most often a pry bar. Yesterday for me it was a chisel, a snap ring remover, and a punch.
Wow .... very insightful your explanation of the engine cadence sound during startup w/ weak cylinder #1 and the following diagnosis (borescope, compr. check). Thanks !!!
I like the borescope which makes it so easy to confirm your suspicions. Nice job!
Ouch - what a tough break for the customer. Love your channel. Keep up the great work - telling it like it is.....Love it!
Another great video! I’ve gained knowledge about making sure one does homework before purchasing a vehicle by watching this channel. Of course, no vehicle is perfect, but some do have an awful track record. You hit a home run and thanks for the content!
Good afternoon Eric and SMA viewers from Fort Lauderdale Florida 71 degrees and raining.
Thank you for the informative video.
How sad, 83 degrees and sunny here in beautiful Southern Az!
Thanks for the tip on Mr wiggles. Just bought one. These are great for checking for valve issues on aircraft engine.
Amazing tools to work with today and having vast knowledge about engines also helps . great video Sir!
Best scope I have ever seen.
Reminds me of towing 20 yrs ago, and I had to take a 1984 Chrysler New Yorker to it's final journey over the car crusher rainbow. It had a 2 liter Turbo with under 100k, that the customer told me had cost him more in repairs than the car cost new. He had seen enough of a car with a engine that was too small to drive all the luxury components of his junk heap, so he was sending it to it's final resting place at the local car wrecker. You just cannot overcome simple physics with fancy turbo technology.
My mom had a 86 Turbo New Yorker that had over 200k miles on it when the transmission let go and it was faster in the 1/4 mile than my buddies 87 Trans Am with a 305 & automatic! That car had 1 headgasket, a water pump and 3 timing belts it's entire life and my dad & I replaced everything in our driveway! The fact that a car built in 84 was still on the road in 2004 should tell you something, it having under 100k miles tells me it was probably a old persons and the car sat all it's life which is the worse thing for any vehicle and the customer probably didnt not know the difference between a torque wrench & a line wrench and would rather have a car payment & dealer service than doing something for himself!
Always good to watch your videos, learning something new every time like using a screwdriver to set the piston...thanks for sharing
I really learned a lot from this. That scope tool is so cool. Thank you for these o really enjoy 🤘🏼🙏🏼
I’ve not heard anything good about them but they are money makers for mechanics. Junkillacs!!! Thanks Eric!
Some of these have a calibration update that injects another "squirt" of fuel into the cylinder to help prevent LSPI. Some believe it's left over carbon that starts the pre-ignition or just the way GDI's are designed. These engines have an amazing amount of oil dilution and direct injection also doesn't allow for any air to be mixed in with the fuel before it hits the bang chamber. I have a 2017 cruze 1.4l LE2 turbo. They claim the issue is fixed but my dealer told me that regular gas is all you run in these cars and I was hitting around 43mpg but came winter, the engine started rattling like it was having some hellacious spark knock. I started doing research and found that people were having problems with their engines grenading from LSPI and the TSB only diagnoses the problem with Symptom: Engine misfire detected, Solution: Replace engine. They also in the TSB tell dealerships to update to the latest calibration on the ECM that supposedly fixes the LSPI issue. I had to start running premium in my car and the pinging went away but my mileage dropped to about 35mpg now running premium. The engine also does weird hesitations and feels like its misfiring since I bought it with around 85,000 miles on the clock. The calibrations were the latest version so I'm wondering if they played around with the fuel maps to make the car run like shit just to keep the engine from blowing up.
There is more BTU (energy) in 87 octane gas than 93. Unless you can benefit from running higher compression or more boost the lower octane is more efficient for mileage. I would not doubt that they also richened up the fuel maps on the NEW updated calibration to save the motors from lean conditions which would cause preignition.
@@cp6027 The 2017 LE2 in my Cruze does not like 87 at all. It runs fine and gets great gas mileage but there is so much knock retard per cylinder it starts rattling like the engine is going to grenade. Some of them hit so hard that it causes a misfire on that cylinder and I can feel it stutter. I think winter grade is more likely to do it because I didn't notice it until it started getting cooler. It was loud enough to be heard over the radio. I also can torque brake it and roll the window down to hear it rapping like 50 cent.
Ex Cadillac tech here. We had a rush once of about 6 or 7 ATS’s with the same 2.0. All had cracked ring lands on cyl 4. I had one that had cracked ring lands on 3 and 4. GM released a recall to update the ECM for this. After that we never saw an issue. I’m surprised to see scoring, as well as a different cylinder lol. We always were able to replace the pistons and GTG
Thanks for the video Eric.
You have all the fun tools
I resisted the temptation when you showed the Mr. Wiggles in a previous video. Reason being I just purchased a new one with more than one Camera. One Beer and Cadilliac Video later, I am tracking a Mr. Wiggles Camera to my shop. DANG YOU !!! ERIC ....heheheheehe
I'm glad you left a link to that borescope. I just ordered one. Amazon had it on sale.
'HEY NOT BAD ONLY 8 TROUBLE CODES" Very funny ,
He wasn't joking.
8 is not a large number of codes for a car built in the last 15 or so years.
I worked on a 2021 Ram last week that had 68 fault codes. Most of those were caused by a weak battery.
Didn't think these engines were that bad, good to know
They’re not that bad. She was probably using regular gasoline in it. You can’t use it. Top Tier 93. 87 grenades it.
Hi, Mr. O. It is interesting to see how they get so much power out of a 4 cylinder engine. It seems very high tech. Thanks for sharing! Stay Healthy!

The real ouch is that the owner didn’t learn a lesson after the first engine failed…he should’ve sold it after getting it going again.
@@deplorablelibertarian
Ya can't insult someone for not knowing any better. Whoever convinced them to do a second engine without researching the known issues is the one who is at fault, intentional or not.
Most people don't have a clue, that's why they bring their rig to a mechanic because, hopefully they know what to do.
Whenever I do a repair for anyone, the first check is known or common issues, that may not be what I'm fixing, but having that knowledge helps answer other questions they might have later, plus most of the people are friends or family anyway, so I might as well know what's coming.
Evening Eric👍👍
The bore scope is very useful. Great video, thanks
This was a really interesting video. Thanks, Eric!👍 👏
Another fine video Eric. I had 2 favorite Auto channels but the other one has gotten so silly I skip thru most of it. How about you & the family pack up & move to middle Ga. We need a top wrench here. No rust in the eyes.

@@floorpizza8074i can't even stand to watch him anymore, it became terrible after he opened his own shop.
Eric, turbos on small displacement engines are an engineer's pipe dream as they radically shorten engine life expectancy! You increase cylinder pressure at your peril. Gas money saved by high efficiency tuning will be spent on engine repair. Three engines in 108k is a crime! Great show us how video! Thanks!
No, the pipe dream is the EPA setting the rules for how it's tuned to pass their fantasy emissions regulations! None of those idiots know how to change the oil in a lawn mower so expecting them to know how to tune any engine more less one with forced induction is laughable!
It's a real shame Toyota went from their tried and true 6 cylinders to a turbo 4. All in the name of slightly better emissions and MPG.
@tul9033 Toyota could not meet the new EPA standards with their V6 engines any longer that is why. Thank your elected administrstion.
@@tul9033 I put 300K on a '90 Eagle Talon Tsi which had a turbo 4 without engine failure, so one can make a turbo 4 that will last a long time. Mitsu proved it with the 4G63T engine.
The issue is all the fuel economy crap on modern engines like low tension piston rings and what not that makes these engines unreliable there's plenty of turbo 4 cylinders from the 90s that last a long time
In fact, you saved the disassembly of the engine head with the camera, technology! Thanks for the clip
Thanks for the clear flood mode in checking for a bad cylinder compression -
good diagnostic process for those DIYers without a fancy $$$ bi directional scanner
Another GM bad design bites the dust. Do you remember when those beautiful Caddy big blocks would run forever? What happened to Cadillac quality?
JB Weld in cylinder 1. and run the engine @ 10,000 RPM for an hour, the crankcase will release the broken piston and ventilate the block and the new 3 cylinder will burn less gas
¡No quemará nada de gasolina!
While you might manage 10K rpm with a mechanical system, modern ECUs prevent that unless the source of the rpm is the transmission, i.e. being stuck in gear going down a steep slope.
Very cool new tool my endoscope isn't anywhere near as clear and to be able to flip like that is awesome thanks Eric for the info and great video!!!

Direct injection engines usually seem to have more issues and everyone is making their engines direct injected
@@Jihadbearzwithgunz Yep.. The fuel likes to flood down into the oil.. and then people just drive it that way and engines tend to like good lubrication.. lol... Might be important
@@calholli yes sir and gas is not a good lubricant unless it's diesel to a point
Excellent video and editing with that bore scope.
Excellent video my man!
Great fault finding skills Eric, I got to get me one of them cameras though, looks like it can be used for many things.
Had to replace a car this year. Reading about the high compression turbo'ed direct injected engines from multiple mfgr's having issues, carbon buildup, or short life I oped for an older style engine. I wonder if I made the right decision. Are the newer engines really not as reliable?
As Scotty said "The more they overthink the plumbing, the easier it is to stop up the drain."
I picked up that same borescope about a month ago. We have Snap On scopes for the shop, but this one is leaps and bounds better. Everyone in the shop was impressed with it and one bought one.
Is Mr Wiggles waterproof? Asking for a friend 🤫🙈
Danger Wil Robinson!!
Working at a Honda dealership some years back, performing a 60K service including spark plugs, I unknowing had a Snap On MAGNETIC spark plug socket that had a piece of magnet break off and drop into the cylinder.
With the 2.2L aluminum head, it fell right down on top of the piston.
When the service was complete, I fired it up. It sounded like an empty spray paint can being shaken at high speed for about 3 seconds, and then it was ejected out the exhaust valve, which closed on on the piece of magnet chipping the valve and damaging the valve seat causing an instant dead miss.
Long story short, the dealership ate the parts and I ate the labor. After the service manager called the customer and put him in a loaner car he told all the techs in the shop that if anyone had magnetic spark plug sockets, to throw them in the trash.
Mine was the first one in the can and I will never forget eating that job.
I hope that none of you will ever have too.
Absolutely cool boroscope. Quick diagnosis.
Your video is Tops, man. Best on UA-cam
If this TI wasn't on it, I would have guessed a bent valve, so I learned a thing here. The spot in the wall you see is wear due to piston load/slapping and not deformation due to coolant jackets being close. Built to a budget that was evidently a bit too low to make the engine reliable.
A bad GM 4cyl turbo?
Naw.
Can't be.
No way.
There's no way I'd buy a GM 4 cyl turbo in anything. Including that fancy new Colorado. Nope.
That inspection camera was great, that piston head looked like a vault door pattern.
So clear and close, what a handy tool :-D
Great video Eric. At 15:49 The larger valve on the right is missing much of the outer edges. All the valves in that cylinder #1 are showing this edge erosion to some degree. I could be wrong. I don't see the same valve damage on the second cylinder (#2 I believe).
Eric,
Great video - thank you.
Perhaps you could do a video (WUW, etc) on why modern automobiles have to be so complex* - which causes them to be more unreliable and more expensive to repair. I understand that some consumers want comfort, aesthetics, and performance, manufacturers want to reduce costs, be competitive, and profitable, and governments mandate safety, fuel efficiency, and emissions standards. But is it technology just for technology's sake?
BTW I drive a 2006 4 cylinder 'economy' car with minimal features. It gets me from A to B, doesnt turn heads or make my neighbours jealous. It doesnt have 4/all wheel drive - needed for less than 2 percent of all miles driven. And it doesnt have 9 passenger seating - for one person 98 percent of the time. I also drive the speed limit. *I understand 'complex' is a relative term.

5:00 This explanation is priceless.
Borescopes are handy tools as are the leak down tools....and as always, way to go young man
Thats what you get when using low octane on turbo engines.
Isn't it supposed to detune the engine a little if it senses a ping due to 87 octane?
Right there is the major problem IMO. If it's got a turbo, you need to be running premium gas.
More fantastic GM engineering. And people wonder why I call GM junk when they ask me my opinion of them. Seems like they have taken a willing dive off the cliff, and don't really care. So sad.
Great video and analysis as usual!❤❤❤
