I am a Mazda Technician. Though I havent been with Mazda for very long, this is by far the worst damage I have seen in one of these engines. This looks like a little bit of customer abuse and a whole bunch of shady mechanic work. Great Video!
RTV clogged pickup, bearing spun due to lack of oil, the rest is history. Seeing how clean the head was, I dont think this was customer abuse, clearly oil was changed. Only if the customer did his own maintenance would you have a point.
It's clear this an intentional destruction. I've seen dozens of gearheads take an engine on its' last legs and intentionally over-rev it to destruction. That's what this is.
I've seen folks get into a cold car or truck/start/ when it fires, their foot's on the floor and they rocket down the street as fast as it can go. This is done every single day until it explodes. They go get another & start all over again.
The turbo models were known to burn oil through the valve stems. This combined with the factory recommendation to only fill the oil about "1/3 full" at service time created lots of people running low on oil.
My phone number is on every engine I’ve done work on more than valve covers on. It’s 7, 3 have hit the scrapyard, one I’m driving, one my aunt is driving, one got sold to someone who scraps, and one got sold to someone I’ve seen on a daily basis.
My theory of what happened: 1. an oil leak developed, probably in the bed plate area. 2. Inexperienced mechanic assumed that the problem was the oil pan gasket. 3. Replaced oil pan, and gasket. 4. Oil still leaking. Inexperienced mechanic assumed the pan gasket was still the problem. 5. Mechanic SLATHERED on gasket seal to try to stop the leak and told the owner not to come back. 6. Owner drove car to the middle of nowhere. 7. While driving, a piece of gasket seal got stuck in the oil pick up. 8. While STILL LEAKING OIL, the oil pressure dropped. 9. Owner ignored warning lights. 10. Bearings spun and heated up the bottom end. 11. Cylinder 2 (or 3 not sure) broke and started ripping up the bottom end. 12. Owner kept driving the car despite all the horrible noises it was making. 13. Engine seized while the owner was still in the middle of nowhere and forced the owner to stop.
What i find the most impressive with this engine, is the fact that it still ran in spite of all the damage, until the timing chain snapped, which finally put it to rest.
@@dans_Learning_Curvethey either ran it out of oil or the drove it knocking for long enough that bearing material clogged the pickup and it went full meltdown. Based on the quality of these engines and the fact that this engine looks very well maintained, I’m willing to bet that this involves an “oopsie” during an oil change.
Yesterday evening I watched your video about the Mazda Skyactiv-G 2.5 and thought it would be great if you could make one about the Skyactive 2.0. This morning I woke up, turned on UA-cam and couldn't believe my eyes. My engine is on your channel! Thank you for your contribution to the community. Keep up the good work 🙂
I daily a 2014 Mazda 3 with the 2.0L & 6spd manual. Purchased new and now has 140k miles. Zero issues. Just oil changes. 👍🏼 I have been changing the oil at 3-4K miles (40-50% oil life showing) with synthetic 5w30 all these years though. 🤷🏻♂️ Lots of short trips, idling with AC on full blast (FLORIDA!!!) and the direct injection nature of these engines had me worried about using 0w20 and I have done several Used Oil Analysis to monitor engine wear all these years. 💪🏻
The only thing saving this engine from more failures is smarter drivers.😅 The heavy use of RTV reminds me of a F 150 with a 5.0L I had with gobs of RTV on the Valve cover. Got worse the further you got down.
These non turbo Skyactiv engines are really something. When this guy who deals with core engines daily says there is barely any demand for these engines and its hard to even come accross a blown up core engine, you know its a good engine. Its insane to me that somebody managed to blow up a known to be reliable 146hp 4 cylinder to this degree of damage.
Eric, everyone who watched this video is probably equally amazed as you. It took real "skill" to destroy an engine that badly!😱 To quote Garfield The Cat: "Every time I think I've hit bottom, someone throws me a shovel!"
That L84 section reminds me of the first time I saw a Desk Ornament in high school auto shop (yes, I'm old enough to have had that) which was a GM diesel locomotive piston that had all 4 valves embedded into its crown. I hope plenty of kids get to see this one.
What a change from last week's teardown Eric. Last week, almost no damage. This week, carnage. As always, thanks for the Saturday night entertainment. I got a good laugh when you made the reference to the "Jump to comclusions mat." :) Enjoy the rest of your weekend.
This was genuinely impressive! So much carnage, it does make you wonder how it happened. (I mean, oil starvation, as you point out, was the primary cause, but you can just pull over when the oil light comes on.) Clearly, someone kept their boot in until the engine refused to turn any more.
Doing the regular maintenance as intended helps with longevity of most engines. Also, if you live in an area where they use salt on the road, then you should have the undercarriage washed once the snow and ice season has ended
@@johnathanedwards9054 I'm in Wisconsin and honestly I don't think you can rust one of these out if you try. It gets a little here and there but the rust never seems to penetrate
1:29 - As the owner of a 2017 Mazda 3 with this engine, hearing this information for the first time has made me very smug. I always knew these were good, but now that I know these entire engines sell for $600 used is incredible. Shit, I might just blow mine up tomorrow for the learning experience. I could buy 8 of these engines for the price of your average sold RTX 5090 on ebay right now.
I have the 2.5t, which he's had before. They're about the same price, if memory serves. I'm eventually rotary swapping my 3 and have debated sending the original engine to Eric when the time comes.
Got home early from the bar. That means I'm watching on Saturday night instead of Sunday morning. And maybe this means I'm getting old, but I'm super stoked to catch the teardown on the night of release 😂🥰
I love your teardowns of smaller, more passenger car focused engines. I am looking forward to you tearing down a Honda K24 engine - I live in Japan and drive a 2006 JDM Odyssey RB2 (4WD) with a K24A 2.4L iVETC. It has barely any miles on it (65K, most of it from its grandpa first owner) - and watching your channel made me take the fluids way more seriously than I did in the past. The car goes in for “inspection” every 2 years - but they never replaced the air filter in 18 years! It was a black nightmare!
Great Video! I like how passionate you get when you try to visualise what happened. Like you I find it hard to imagine the noises and vibrations associated with this failure AND YET the numbscull driving just kept his/her foot on the loud pedal! INCREDIBLE damage for such a moderately powered engine! All of the drivers senses would have been assaulted but this poor engines death throws you would even have been able to taste the superheated metal/oil/coolant vapour ! On the other hand it does demonstrate how much abuse these machines can take before finally letting go.
Yes, another outstanding video. I learn more with each video you produce. Thanks for the update on your ICE sculpture. That will make a spectacular ornament.
As a lover of my 2.0lt PE-VPS engine, I was awaiting (and dreading) the day this engine featured😅 but good lord!! This wasnt a tear down, it was a crime scene investigation! You can find the workshop manual online for free?! But I guess whoever killed engine wouldnt know right from left.
the rtv plugged the bearing pump. the rod let go, smashed the balance shafts, which broke the timing chain. I'd say the customer went back with a complaint after the oil pan swap, and it came out of the mechanic's pocket...hence the sloppy job. great video!
One thing I noticed is the gap on the #4 plug is absolutely massive. Just like the autozone special on the bottom, clearly corners were cut up top too. Edit .... or not? Wow, that valve train. Super duper clean!
I'd love to know what that thing sounded like when it came apart. That truly is an impressive failure and I've seen some stuff. 2-stroke outboard engines absolutely nuke themselves when they come apart, but I still don't think I've ever seen a counterweight bent! Wow!
We had a 2015 CX-5 with the 2.5L SkyACTIV engine. blew up 1month past the powertrain warranty when the oil pump failed for a known issue - Mazda even has a TSB for it (01-023/15). I provided oil change proof etc. They refused to do anything to help, i even appealed to corporate and was told to pound salt.
I am surprised they did not goodwill the warranty. My dealer absolutely would have in that situation, even if the dealer hadn't, Mazda Corporate would have. I had a 2016 CX-9 recently get most of the repair cost of a cylinder head covered when they were 12,000 miles past the warranty extension for that TSB. Very strange indeed.
I'm going to guess that someone knew this engine was toast, thus the ATV pan reinstall. Got a replacement engine for the car, blew this one up for entertainment, swapped engines, and gave this one back to the yard. I agree that it was probably driven without oil, most like due to a damaged oil pan and perhaps thought they could salvage the engine, but realized it was too far gone, leading to the entertainment portion of someone's video, and then you got it.🤙
These are great engines. My aunts 2016 cx3 with about 73k run like an absolute top and is nice and quiet. I have seen one other skyactiv with a damage worse than this. It was on a Mazda 6 that drove through water and had a giant hole on the side.
Loved your comment of the "bearing pressure tensioner". I had a good laugh at that one. Couldn't have been more accurate though! That sump pan was so full, of bearing material, you just knew the bottom end was going to be a total mess. This teardown had it all. Really enjoyed it.
Looks like RTV from the pan starved the oil and toasted the crank temping the journals and rods to explosion results . Amazing the amount of filing from the block grinding. Wow
Technically that’s Atkinson cycle, it would have to be boosted to be Miller, and it’s achieved with a long duration intake cam as well as variable cam timing.
Change your oil at 3000 miles or 1 year and your engine will live 400,000 miles. And then it will only need a simple overhaul in order for it to run another 400,000 miles. Check your oil on occasion. Check it far more often if you see a few oil drips on the driveway the way I do with my airport car, a 2001 Subaru Outback H6. Keeping an engine from being in one of Eric's videos is not hard folks...
Man, that's some professional-grade destruction! Only 146 HP and all that damage? LOL. Crazy destruction. Thanks, Eric, for sharing all these great teardowns. Take care, man, and stay cool!
I have a Theory: the car got an oil change and the shop forgot to put oil in it. Engine starts making noise and the customer takes it back. Shop says, “we can fix this! We didn’t do anything wrong!” And after a couple attempts to try and fix the problem, they tell the customer that you need to “break in” the repairs we have done so just drive it hard to “set the rings”. So, they did and Snap, Crackle, Pop, and Boom!
I just replaced one of those last year. Driven by a late 50's lassie and maintained. ~75K. When I heard the shop had told her it was "blown", I told her I'd take a second look wondering if they weren't trying to scam her .. but nope .. gold rush in the pan. Never had the time to do an autopsy, but I was a bit surprised to find a dead Mazda under those circumstances. When asked why it failed, best I could guess is Monday morning saki hangover in the bearing installation department.
I have a used water pump off of an '82 Mitsubishi Cordia 2.0 liter that has sat in my garage for 32 years and only has 110,000 miles on it. I'll sell it to you for three easy payments of only $59.95 and with some JB Weld, RTV, and Bondo you should be able to make it work....
Congrats to new company president W.P. You are right - the rpm must have been astronomical when the rod let go, to do that much damage after the mains ran. I think whoever RTV'd that pan just wanted it airtight when the submarine dived...oh wait...8^)
My girlfriend had a 2016 that self-destructed in Dec 2023. She bought it new, so there’s no chance it was owner/operator error. One of the bed plate bolt heads completely broke off. The bolt head fell straight down and the counter weight on the crank shaft pounded the broken bolt head into the upper terrace of the oil pan. It caused a massive oil leak. I’m glad I took photos and a video because it’s one of those things that no one would ever believe unless they saw it. I bought a new OEM bolt from Mazda, and an aftermarket oil pan. Extracting the broken bolt was difficult but I got it. Finished repairing the car, and traded it for a 2021. I kept the two bolt pieces, and she kept the oil pan. Mementos.
I appreciate the office space reference! Also, for a clue for the mileage, my 2014 mazda 3 with the 2.0 had more carbon buildup than that one at 53,000 miles.
I worked at a VW dealership back in the mid 1970s. Now this is 50 years later, so things may be different now. When our air guns got weak, we could get them back to full power by replacing the little seals on the rotor inside the gun. Took a few minutes, and the Mac Tool truck had the kits on hand. My gun was a Chicago Pneumatic. But other guys had different brands and they all were rebuildable.
The car quest filter is a wix. That used to mean more than it does now. The holes on the inner sleeve on my genuine wix are tiny compared with the old ones. I’ll be checking them out at the store next time to figure out what brand I’m switching to for my crv.
You're such a gem of the automotive community. Appreciate all you do. That being said these are actually shockingly durable engines. It's not easy to trash one. Edit: I've heard of forged internals but never forged externals. LOL And that super clean top end stinks of massive oil leak. It's way too clean. Looks like it got daily fresh oil.
The only mastic I can see with this engine was there was too much mistake. Sorry typo error, the only mistake is too much mastic! Lol! Thanks, excellent video.
Regardless of the noise this must have made for goodness knows how long, it is seriously impressive that the engine still ran long enough to do that much damage to itself.
I am a Mazda Technician. Though I havent been with Mazda for very long, this is by far the worst damage I have seen in one of these engines. This looks like a little bit of customer abuse and a whole bunch of shady mechanic work. Great Video!
I was thinking abuse, like a boy racer burnout, drifting thing. Stolen car? and just blown up on purpose?
RTV clogged pickup, bearing spun due to lack of oil, the rest is history. Seeing how clean the head was, I dont think this was customer abuse, clearly oil was changed.
Only if the customer did his own maintenance would you have a point.

Yep.
Quality time with the wife.....she doesn't get it.....something about me being cute, but stupid.

That’s my story and I’m going to stick to it
Yea,seen that theory on the old Caddy Northstar engine also, thumbs up great video
That's very linear. 🙂
Alternative theory, he ran a single turbo 500hp and that thing said bye bye
as soon as I saw the oil pan, I immediately thought this. Assuming it was a rental car, they'd also throw a bandaid fix on it like that too.
What i find the most impressive with this engine, is the fact that it still ran in spite of all the damage, until the timing chain snapped, which finally put it to rest.
In my 20 years with Mazda dealerships I have never seen carnage like this. Especially on a skyactiv engine.
Do you think it ran out of oil?

You can’t get oil varnish if you don’t add oil!
Or constantly replacing it from a leak

I have a Theory: the car got an oil change and the shop forgot to put oil in it. Engine starts making noise and the customer takes it back. Shop says, “we can fix this! We didn’t do anything wrong!” And after a couple attempts to try and fix the problem, they tell the customer that you need to “break in” the repairs we have done so just drive it hard to “set the rings”. So, they did and Snap, Crackle, Pop, and Boom!
This was a good story, even plausible I’ll believe it
I just replaced one of those last year. Driven by a late 50's lassie and maintained. ~75K. When I heard the shop had told her it was "blown", I told her I'd take a second look wondering if they weren't trying to scam her .. but nope .. gold rush in the pan. Never had the time to do an autopsy, but I was a bit surprised to find a dead Mazda under those circumstances. When asked why it failed, best I could guess is Monday morning saki hangover in the bearing installation department.
Excellent video!
Mazda has always made STRONG engines!
NOT THE WATER PUMP!!!! I NEEDED THAT!!!!
Buddy were you in for a surprise today lol
I have a used water pump off of an '82 Mitsubishi Cordia 2.0 liter that has sat in my garage for 32 years and only has 110,000 miles on it. I'll sell it to you for three easy payments of only $59.95 and with some JB Weld, RTV, and Bondo you should be able to make it work....
Congrats to new company president W.P. You are right - the rpm must have been astronomical when the rod let go, to do that much damage after the mains ran. I think whoever RTV'd that pan just wanted it airtight when the submarine dived...oh wait...8^)
No preferential treatment there! No need to inform HR
😮good video, with a great wow factor! Thanks.
chain broken is a consequence not the cause.
The sudden stop from High RPM due to the con rod getting stuck was too much for the chain and it broke
I am absolutely amazed at the amount of carnage in there, I can imagine it sounded pretty spectacular as it was letting go in its final death throes.
I save your videos for Sunday. They go so well with my morning coffee. This morning I felt like I was drinking Starbucks instead of Maxwell House.
My girlfriend had a 2016 that self-destructed in Dec 2023. She bought it new, so there’s no chance it was owner/operator error. One of the bed plate bolt heads completely broke off. The bolt head fell straight down and the counter weight on the crank shaft pounded the broken bolt head into the upper terrace of the oil pan. It caused a massive oil leak. I’m glad I took photos and a video because it’s one of those things that no one would ever believe unless they saw it. I bought a new OEM bolt from Mazda, and an aftermarket oil pan. Extracting the broken bolt was difficult but I got it. Finished repairing the car, and traded it for a 2021.
I kept the two bolt pieces, and she kept the oil pan. Mementos.
I remember that Magnum v10 with the broken crank and all rods except for 2 were broken
My favourite videos always start with custom inspection ports.
5:58 hey Eric you forgot a bolt 😂
I appreciate the office space reference! Also, for a clue for the mileage, my 2014 mazda 3 with the 2.0 had more carbon buildup than that one at 53,000 miles.
Eric your awesome take my 2 bucks and save a waterpump 😂Thanks!
I’ll do what I can for the next h20 pump in need.
Thank ya
Another great teardown Eric! I have to say, why did they even put the bolts in the oil pan when they crazy glued it on 😂
Can’t wait to see these at your garage.
This was a good one. Like he compressor motor. The more it was torn down. The worse it got. This was fantastic. Job well done.
I worked at a VW dealership back in the mid 1970s. Now this is 50 years later, so things may be different now. When our air guns got weak, we could get them back to full power by replacing the little seals on the rotor inside the gun. Took a few minutes, and the Mac Tool truck had the kits on hand. My gun was a Chicago Pneumatic. But other guys had different brands and they all were rebuildable.
The car quest filter is a wix. That used to mean more than it does now. The holes on the inner sleeve on my genuine wix are tiny compared with the old ones. I’ll be checking them out at the store next time to figure out what brand I’m switching to for my crv.
Don"t be lazy go to the dealer and put original filter
A comment for the algorithm. What a sight!
That section of block with embedded conrod would almost make an interesting base for a small table.
Wow, my weekend is now complete. 🤤
Thanks very much for another great video. Wow, what carnage. See you on your next one.
You're such a gem of the automotive community. Appreciate all you do.
That being said these are actually shockingly durable engines. It's not easy to trash one.
Edit: I've heard of forged internals but never forged externals. LOL
And that super clean top end stinks of massive oil leak. It's way too clean. Looks like it got daily fresh oil.
Thanks! I have this type of engine on my car.
I believe someone wanted to use this one for making metallic paint...
The only mastic I can see with this engine was there was too much mistake. Sorry typo error, the only mistake is too much mastic! Lol! Thanks, excellent video.
I was just thinking about checking the channel for a new video, and I clicked on another and boom it was there.
Thanks for making these awesome videos! Your hard work is appreciated.
You need a "desk ornament" category in the drop down list on your site! I'd love to see what you have!
Congrats on the new owner of the company.
Present and accounted for!
sweet find eric thank you kindly!!!
@24:46 "Unless some smooth brain" That's a new one for me! I'm going to steal that.
Thanks for another fun teardown!
Regardless of the noise this must have made for goodness knows how long, it is seriously impressive that the engine still ran long enough to do that much damage to itself.
