Here's weekly dose of your catastrophic engine forensics! Every week you can find a new teardown of some abused, misused and/or poorly designed engine. Here are some of my favorites:
Toyota Prius CARNAGE • BLEW UP A PRIUS?! 2010...
Incomprehensible Honda J35 Failure • Obliterated Honda Acco...
6.7L Cummins Destruction • DEMOLISHED 6.7 Ram Cum...
The WORST Kia Engine Failure • Taking "Blown Up Engin...
Today's teardown is a 2.3L "Duratec:" or "MZR" Mazda/Ford engine that can be found in most of the mid-late 2000's Mazda and Ford Lineup. This includes the mazda 3, Mazda 5, Ford Escape, Mazda Tribute, Mercury Mariner, Ford Fusion, Mazda 6, Mercy Milan, Ford Focus, Mazda CX-7, etc.
There are many different variants of this engine, some turbocharged and direct injected, most of them naturally aspirated.
This particular engine is out of a 2005 Mazda Tribute that my brother bought to fix and sell. I sourced him a used engine to replace the bad one, and this core sat in his garage for a while. This engine has 158K Miles on it and its pretty clear what happened here. Many of these 2.3L's meet their demise in the same way and its still apparent there is demand for them because they are still relatively expensive engines.
Why am I doing this? My name is Eric and I own and run a full service auto salvage business called Importapart. Part of our model includes dismantling blown and bad engines to salvage the good parts to resell. We do not rebuild engines, merely supply parts to those who do.
I really hope you enjoyed this teardown, as always I love all of the comments, feedback and even the criticism. Catch you on the next one!

Yeah, I have quite the track record of not draining oil from engines and transmissions I remove from vehicles. Whether that oil ends up dripping down your leg from a RX-8 transmission or creating an EPA-alerting spill on my driveway out of my 3 rotor, I deserve that bus you threw me under. - the brother
I like your old Protege BPT Videos. Been thinking of turboing my DX Protege but the tranny won't like it
I still run my '03 P5 wagon, all stock with the sport stick no less. It still runs fine at nearly 200K on it. Yes, the FSDE 2.0L 4.
@@Shiznit304 Yeah the F-boxes don’t hold up well to boost compared to the G-box. My ‘94 is running stronger than ever, still on its original G-series, though I did destroy the diff once, about 10 years ago. Has a Mazdaspeed Protege LSD in it, all good.
Thank you for the engine! And uhh... Not ALL families do that.... Just saying. So thank you for your generosity.
You must be the black sheep of the family
You're spoiling us with this two-videos-a-week schedule.
Agreed but I am happy with the results. : )
Keep the new tradition👍🍸
It's nice, as long as he doesn't get burned out doing it.
That Tribute lays down a pretty sick beat.
I was nodding my head to the beat
If my Mazda starts doing it it'll be much more sad 😂
Came here for that comment! Sounds like a steel drum band!
Lol I just put the same comment
Syncopated!
Sounds a bit like a skip-fire engine
That engine was trying out for the band.
That drum solo...
Been following this channel since there were maybe 10 teardowns uploaded, and the fact that there’s a midweek video most weeks now is freakin awesome!
When I joined he had 67,000 subs. Now he's exploded to 308,000 and growing!
10:15 - Cranks without a keyway are complete madness. It's negligible added cost and manufacturing time, while negating the need for a special tool to do a very basic service. Even if you aren't messing with the engine's timing, harmonic balancers do fail and need replacement on occasion. A keyway would make that job very easy.
Yeah, stupid.
Bean counters at work... Probably eliminates 1 step during assembly.
@@volvo09more engine failures, more engines sold - some CEO
Well they have to make compromises somewhere for your precious government.
Some know nothing bureaucrat.
The cams too.
But the oil pump!!! Yeah yeah yeah!!! we'll key that!
Madness.
I grew up in workshops. I ran a mechanical business for 12 years.
One day I'll be in a pub and get to meet some bloke who designs engines. I can't wait for that day to come.
Some people think time really runs backwards and the ancients were the tech people and we lost that tech. Heading for extinction due to our stupidity.
"Now it's time to pull the bearing basket" Bearing basket!!! 🤣🤣🤣🤣
I was waiting for the "Uncle Rodney" reference as soon as I clicked, but the subtle Rodney Dangerfield reference was perfect.
Between the Safety Tote, the cram craps, and the piston nuggets it's always a good time with Eric!
Don't forget to appreciate the bearing basket and the rod bearing concentrate....
A rack of Rod Bearing Concentrate bottles would be a talking point in the awaiting rooms at service centres everywhere....
Okay maybe I looked away and missed it but I didn't see the test! The ever popular test of the piston rod connection system. I don't know, I don't know...
Funny I wondered why he made a comment about that in his next video I watched before this one
Oh snap , your right.
WHERE WAS THE TEST? WHERE WAS SCIENCE?
Eric, you forgot!
It was a running engine.
It’d* be a real pita to film but it would be cool to see two or more competitors’ engines torn down side by side, like a 3.6 pentastar vs a 3.6 gm, and compare things 1 to 1.
yes please. and so many 2.5L!
As well as 2gr and vq35 and j35
You forgot Safety Tote with the chop saw, we almost lost you!
As a master tech of 35 years, I've watched a lot of your videos about the engines that you tear down. It seems to me that the biggest common denominator is that people simply just don't check there oil level frequently enough or don't have there oil changed every 5k miles. We run a fleet of cars of various makes and models and some will use almost 5 qts of oil in 5k miles, some don't. That is the reason we dont do extended oil change intervals in our fleet. We have not ever had one blow up due to low oil level but close.
First, thank you to Ryan for the engine donation. Second, thanks to Eric for making yet another quality, informative, and educational video to expand our knowledge. I am sure this takes volumes of time and money to plan, secure resources, and produce each video. That said, thank you and I look forward to the next one.
I've got a 2.3L 09 Ranger. My biggest gripe with these in the trucks is they only hold 4 quarts of oil. Mines doesn't burn too much, maybe a quart over 1500-2000 miles. But that's still a lot of the capacity. Oil temp is probably on the moon too, even full. I like the simple little turd, but I did also use to own a built MZR in a speed6. As you said, I might be a bit of a glutton.
I love these, and the 2.0 even more. I changed my oil religiously though so that's prob a contributing factor. My profile pictured 05 focus 2.0 had 470k before I sold it to a friend.
my father has a 2007 mondeo with a 2.0l engine and it's well over 300k km. all you need is regular oil changes
Same here, I'm actually surprised with his opinion of these engines. I've had 3 of these in my family, all had over 200,000 miles when sold and ran great! One of them actually DID nearly run out of oil a few times (pcv valve failure and bad maintenance)...it kept going though
I had my 08 Focus with the 2.0 liter go to 230k before I sold it. Still ran great and never had any major issues. Just a spark plug well seal leak. Changed oil every 7500 miles
@@conmanl4959 yeah the valve cover gaskets turning into plastic was very common. I never had to make any major repairs either other than an alternator and a starter.
@@conmanl4959 I sold it to my friend and he didn't even make it to 500K before he totally trashed it and it went to the junkyard. I was actually kind of upset that I didn't get to see that car make it to 500k.
I just looked back, and it appears I have been viewing since summer 2020 and have loved every moment. Eric, please go to Harbor Freight and by a cheap small band saw for cutting stuff up. I am a cabinetmaker and have cutoff tips off 2 fingers, and I don't want to see you get hurt. Chop saws are not your friend.
Ive seen alot of these 2.3's blown up so i cant deny their tendancys but I have a daily driver cx7 with the turbo 2.3. It has 200,000 miles and is still running strong. I drive it an hour everyday on the highway to work, but I also check the oil every 3 is days and change it every 5k miles. Fingers crossed it's lasts many miles yet. Awesome teardown video as always man!
Noo ! Engine knock ? Throw in some a synth , glow sticks , strobe lighting , and you've got a rave.
I remember the 1970's Ford Pinto engine used in a lot of European Fords and some American. It had a spray bar running over the top of the single cam that sprayed lubricant onto the lobes and when owners failed to service and change the oil regularly the spray bar would block up, fail to lubricate and drastically wear out the cam.
Can’t fix lazy owners
The pinto was almost unbreakable even for taxi drivers and builders😂
Fantastic Lighting for the "Bearing Sauce" and the Wear/Damage of the Oil Pump, also very much appreciate the close-ups of the damage.
Great Content, Thank You.
This video hits close to home. Owner of a 2007 Mazda 3 here. Original owner at 107k.
Engine sounds like Prog Rock or Jazz Drummer! 😁👍
Mike in San Diego. 🌞🎸🚀🖖
Back in their day, the L3 was a glorious compromise between the lack of power on the LF and the NVH on the L5, all while getting the same or better economy as the LF.
3:16 It’s a catchy beat, and you can dance to it.
I've got 406,000 miles on my Duratec 25 in my 2012 Ford Escape - besides a few plastic parts breaking due to wear and tear such as the water coolant outlet, the ac condenser springing a leak, and a few fender benders - she's still a great daily.
Here's a big thing about the 2.3 / 2.5L engines; The same bolt size that you use to remove the coil pack when you change your spark plugs, is exactly the same size as the valve cover bolts, not only that, they are literally less than an inch apart from each other. If a clueless person were loosen just one bolt on the valve cover and fails to retighten the bolt to spec with a torque wrench,, it will eventually cause oil to bypass the gasket at some point, and cause oil to be forced into the spark plug area, and thereby into the valve bleeder valve and back into the intake through the throttle body.
This will cause insane idle problems (a gunked up throttle body can turn the escape into a demon), spontaneous shut downs, and total loss of control at the worst possible time.
The simple remedy is to check all your head bolts and valve cover bolts with a torque wrench set to factory specs every time you change your spark plugs.
If you've had a perpetual oil leak, this is potentially where it is found. If it is a severe enough leak, you will see oil pooling on top of the actual spark plugs. not good.
If only the Duratec engineers considered changing the bolt pattern between the valve cover, and the coil packs... then again - cheap is big business.
One of the reasons I like boxers. None of the prophylactic NHV/rigidity stuff.
That run video has a pretty good drum beat to it.
When you said speed 3 owners are gluttons for punishment... sir, I did not come here to be called out.
But you're right. And yes, I carry a gallon jug of top up full synthetic with me everywhere. My 09 has 326000 km and as tired as it probably is, it's still going. I check the fluids every time I climb into it, and its treated me well for the time I've had it. For a C$2500 budget racecar with a long history, i know its going to give up eventually. I'm just gonna enjoy it while it lives
Bearing basket, bearing concentrate…love it! 😂😂😂
Well. It’s certainly NOT the 2.3l engine I had in my ‘85 Ranger.
Was like a little tractor, just keep it maintained and it just won’t die. 😂
Love that engine run video clip. Tear down is going to be great.
Had one in an 07 Focus ZX4 ST. Original owner. 219k, started every time, never consumed or leaked one drop of oil. Bottom of that car was bone dry the day I sold it. Ran exactly the same for all 219k miles. Good low end torque for a 4 cyl, way different approach than anything Toyota or Honda were making at the time. Was nice to have power down at 3k RPM, and not have to be up against the red line into the VVT to get power out of it. Needed an alternator for $400 at 120k miles. Only unscheduled maintenance I ever did on it. Guess I got a good one. Was a good car. 219k on the original clutch, brakes (yes, brakes), everything. Only thing I ever replaced were tires, wiper blades, and that alternator. Averaged 31 mpg for its life. In some ways I wish I still had it.
Agreed. I have one in a '07 Mazda 3. Never replaced anything but consumables. Runs as good as the day i bought it new. Never burned a drop of oil.
Lots of torque for a 2.3
Knocking on the 250K door with my Mazda 5 (2.3)! So far so good!
Don't forget to check your oil level frequently and you'll be fine!
Looking for a manual mazda5 now...many clean 2.3 versions out there but this video scares me. 2012 and later manuals seem harder to find!
this engine played drums for my band in 2003
This channel is something sane in an insane world. Thanks broski!👍
That engine running didn't even sound like an engine. Oops all knock.
Very musical, it had quite a good beat going.
Hey now, it was only 25% knock.
Knock, knock! Oh, gangs all here!
*"Except Subaru!"*
I just got done putting new rings in my '03 Forester. Got tired of 1000 or less on a qt of oil!
The oil rings were glued to the piston. The little oil holes behind the oil rings were filled with carbon that was brown! I literally had to use a drill and a small bit to open them up! I have around 400 miles on it since the engine work. Don't know if I was successful putting it in a 12 step program or will it relapse? LoL 😂😆
My first video(s) a few years ago were the Mazdaspeed 3/6 MZR engine. Full circle.
Alma Boykin's "Familiar" series has a character who becomes known as "Uncle Rodney". He's a talking fox who assists with magic. He can't handle his mage's spicey food. His mage gets sick thinking about what sort of wild catches and finds that Rodney eats.
just started watching your channel, the putting-stuff-in-saw-and-something-going-horribly-wrong gets me everytime lmao
Any engine you tear down, I love watching.
Can't stress how important maintenance is for one of these MZR engines. I have a dead stock Gen 1 mazdaspeed3 with 181k miles on it. I bought from the 1st owner who maintained it meticulously and have put about 40k miles on it so far. The car's been serviced religiously with oil changes every 5k miles. Other MS3 owners tell me that 181k is "above average" for the original engine, but I'm also convinced a lot of MS3 owners mod their cars and don't change their oil regularly
The mid-week tear downs make the week fly by. Thanks Eric and thanks to your brother.
I hear that drummer on a street corner. The guy was playing some 5 gallon buckets, and probably made more than all of us tax free. Motor sounds great!
What do you mean "It didn't sound good"? It sounded downright catchy! Sort of like drumsticks on the rim.
the pickup cutting gave me flashbacks of the guy at our shop who cut open an oil filter using a bandsaw and was SHOCKED how much metal he found in the filter. I lol'd and then gave him my spare filter cutter. Good times.
Thanks for the mid week teardown. That was nice of your brother to provide an engine 👍.
Love all the videos. Midweek surprises are awesome!
"Next its time to cram the cam crap's loose" LMFAO I am Dying!!!
Thanks for another mid-week video! They're great and make the wait till Saturday much easier! 😁
Awesome tear down… I learn something new with each video you drop.
Thanks!
Keep up the great work!
My 2005 Mazda 6 2.3L with 142000 miles runs beautifully with no oil burning or leak issues.
I do agree that non keyed crankshafts are stupid. It especially is a problem if you like making your car fast and they slip. For example modified s55s, n55s and n54s. However it does make timing the engine extremely easy.
I also was look forward to you’re videos on the weekend and then you make my day when you surprise me with a weekday video 🤘🏻
My brother sold his manual escape with 283k miles, it still ran but was drinking oil.
Would like to Mention he changed and checked his oil frequently. He always has been good about checking up on his fluids.
Hey Eric I’m a long time viewer but it never fails to amazing me how I end up learning something new every video you post. Love the videos tho keep them coming
Keep the vids up man , love watching ya tear down engines, especially the bad ones 😮
The placement of the idler pulley is diabolical. Sadly they are the same on the 2.5L to.
2007 Mazda 6 with this 2.3na is my work car. 190k and runs fantastic. But yes, I do the oil every 3k. I’m praying to see 250k before I shake it off. That’s if the glass trans plays nice😁
Bearing basket lol. That was liquid rod bearing it for fuel mileage. Gets changed when you change the oil. If you change the oil
I stumble across your channel about a month ago and I really enjoy watching you break down a lot of the new engines, it lets me know which brand to stay away from, I do have a 2018 Ford Fusion with the 2.5L that runs great with 125,000 miles on it and a 2015 Wrangler Rubicon Hard Rock with the 3.6 with 48,000 miles, Im trying to avoid the Pentestar tick by installing the Baxster oil filter adapter that uses a screw on filter with the anti Drain back valve. Keep up the good work. enjoy your humor.
Thank you for a Thursday morning video (New Zealand time frame)....
You are a great person... Please keep it up....
I'm only here to see you toss the water pump ...LOL
I own since new a 2009 Mazda 3 with this engine and it has 223,000 miles on it.
I had a couple of emission related issues and that's about it for the engine.
It doesn't burn a drop of oil between 5000 mile synthetic oil changes.
This is by far the best engine I've ever owned.
I have virtually the exact thing going on. 260000 miles,,never burns oil, drive it every day
So where was your engine built????
Window sticker says Japan@@JohnSmith-yv6eq
That may explain it.
There appear to be significant quality differences between Japanese/ European cars manufactured in USA/Mexico
and those made in their "homelands".
@@rhino6285
Like to see you tear down a 2.0 GM diesel that were installed in Chevy Cruze
Rodney was surely knocking on this motor.
I still daily drive a 2008 MazdaSpeed 3. STOCK! Started burning oil around 90k, was consuming it at an alarming rate(like 1qt every fuel tank) when LSPI finally killed it at 157k. The engine never lost rod bearings, ring lands got crushed and cyl2 went to 10psi.The car got oil changes ever 3000-3200miles(at most). Have a new Gen2 based longblock in the car now, 16k miles and SO FAR it hasnt consumed any oil
The camshafts not having a keyway is the primary reason I will never do any work on the family 2009 Mazda 3 Neo BL. I'll do oil, plugs and filters - but nothing else.
As for run videos of failed engines. Watching one of the 105 series Landcrusier 1FZ-FE my friend bought with broken ringlands for $500 (pistons 1&6 - was turbo'd), ran and sounded like normal turbo 4 cylinder - but still with similar power to what it would have been stock.
Outstanding video
I enjoy them all.
Authentic mid week stuff 👍
We didn’t complete the scientific variable compression test? What is this world coming too!?!
i lovely your teardown videos of good or bad engines such an incite into the good and bad thanks for all you do and show us
That thing runs like it's about to feel the air of night
I love my 03 focus 2.3 but I'm meticulous on maintenance. I honestly wish I still had my zetec 2.0 though It seemed to be better balanced. The duratec vibrates a bit more than I like.
I have a 2011 Mazda 3 i with the 2.0 currently. I probably overpayed for it but desperately needed the car at the time. When I was told "the second gen are the worst of them", I was rather disheartened. But even knowing it largely comes down to how it was maintained, hearing you say it's a good engine is a bit of a relief.
Man that engine run video had a rad back beat to it! It would take 3 spoons just to make that again....
interesting - thanks for the vid. I had a 2.3 MZR in a 2009 Mazda 3 5door - put a bunch of miles on it and sold it to another guy who still has it with no issues. I admit I do change oil regularly with decent product so maybe that's the difference? It did have one of the more difficult oil changes - cartridge filter with a stupid plastic under guard you had to take off every time you changed the oil, (maybe that's it? folks are lazy and just don't change the oil because its a little more difficult?)
Knockeroni and cheese? Great one Eric.
You forgot to do the "Test" with the Hammer! LOL
Love the "engine autopsies". Would love to see an A25A-FKS teardown eventually.
Yeah, in the speed3/speed6 community it's very common for a balance shaft delete. More oil! We need it when our turbos burn all the oil and destroy themselves!
I just love watching you tear downs just great
That engine drum beat made me think Mr. Eric was gonna rickroll us.
man the bmw at the end had its shit ROCKED
@3:20 you could play that on a loop at burning man festival and the crowd would go nuts
Been to burning man 11 times, and you aren't wrong about that. Just throw some bass and flashing lights and you'll have a huge crowd
Thank you brother of Eric! Great video. Eric. Thank you!
Special thanks I DO CARS I picked up the timing chain from this motor today . I was in Missouri on spring break from Cedar rapids I clearly enjoyed going to importaprt. I can't wait to come back for more broken parts
Hi. I’m in A town near Glasgow Scotland. I watch all of your videos with interest. It’s great to have content that doesn’t have the usual over produced crap in it. I think the tear downs are great I I like the stuff where you get a piece of crap running again, like the Miata (Mazda MX5 to us Brits)!!!. I find that I learn much more from those videos. All of your content is great. I love it all and see you on the next one. Thanks
did you watch the Bentley teardown?
That beat was sick. Almost "TOOL" like. Not a tool, but TOOL.
I had an 05 Mazda 3, got it one year old and kept it until 2016 with 150,000 miles and it was a great car in all aspects. Never used oil. Wish i had kept it.
My 2008 Ranger with the 2.3L has 181K miles, uses no oil and runs great. I use Mobil 1 and i change the oil every 8-11K miles.
Thanks for the birthday present! Appreciate all the hard work!
My 2007 Ford Ranger had he 16 Valve 2.3 and it was great! never had any serious issues with it. I changed my oil every 3K miles and kept it clean. When I sold it, it had 270,000 miles and still ran great!
Thanks. Great videos.
Gerotor oil pump. Thanks to your brother and I enjoyed this video. My son's early RX-8 (which he tracks and autocrosses) original rotary is till running well with over 100K miles on it so far - those daily Italian tune-ups probably help. I wonder how long my 2020 WRX will last considering I got over 216,000 miles on my '98 Neon Expresso - which I also autocrossed and ran road courses (plus one drag strip day) on the same engine with zero repairs. Guess we've been the Wednesday build owners! 😀
wha-wha-wha-WHAT?! NO SCIENTIFIC TEST??
Glad to hear confirmation on the 2.0 Duratec Ford being good. '09 Focus owner here. I am good with maintenance, though. The DMF makes a little noise, but all I've done engine wise other than maintenance is change the Valve cover gasket. Oil was seeping past it towards the exhaust manifold and had the oil burning smell.
My dad owned an 06 Mazda 3 with the 2.3. He drove it to 220k miles before we sold it to a classmate at my auto tech school. He fixed it up and as far as I know, it’s still running.
When we sold it, the engine was burning about one quart every four days, or every time the gas tank needed to be filled. 😂
