This is a teardown for the books! Some of you have seen this engine floating around in the background of previous teardown videos. I've been avoiding this one for a month or two, and have burned through all of my "easy" engines. Decided to rip the scab off, and get to this 5.2L BXA Audi V10 core that came in. I knew nothing about it. It was cheap, not a high risk engine. This was filmed over 3 different occasions, and required a lot of on the fly research to get it apart remotely correctly. I'm hardly an Audi or VW guy, and this is the first engine of this type I've ever torn down.
The 5.2L BXA came in the Audi C6 S6 starting in 2007. They are rated 435hp and 398lbft of torque. Personally, they seem incredibly complex for the power they make however they do sound pretty amazing. This particular engine was pretty pooched. Whoever was behind the wheel when this happen tried to power through whatever the situation was, and it wasn't the right call and it likely cost them their car as it was junked after this.
I really hope you enjoyed this teardown, it was a lot of fun to learn how it came apart both the right way and the wrong way.
As always, I appreciate all of the comments, feedback and even the criticism. Catch you all on the next one!

This is comedically accurate if you’ve ever worked on any of their 2000’s V8, V10 engines. Nothing disassembled easily and is even harder to re-assemble because you’ve forgotten where and how components go back together after it took you a week to disassemble it, a month for parts to arrive, and then a week in meditation to motivate yourself to work on it again.
Lol!
Accurate lol
i thought it was just me that stewed like that
I really think these are "Disposable" cars. For what they cost I would think they would be more serviceable.
@@brianallen9810 kinda weird- i have 180k on my car now. its not rusty and it drives fine. if it was a 82 ford anything it would have been at the junkyard years ago. what do you think makes them disposable?
You say you read comments so I wanted to let you know things i absolutely LOVE about your channel. No stupid music, no loud stupid intro graphics, no fake excited yelling about boring stuff, no shilling for VPN or gaming companies I'll NEVER touch, and no shilling for hello fresh (not fresh). I love the way you do what you do and I hope as you grow it's without the previously mentioned annoyances. I don't know what I like, but I KNOW what I hate. Also, just subbed.
And no thumbnails making stupid faces.
+1 I really appreciate the down to earth and calmness of it all with a flake of sarcasm and rhyming😃
Me too
I’m glad someone said it
Definitely as above!!
Love this channel.
Man, the complexity of these engines is just nuts. No wonder repairs cost a lot.
That complexity is why I will never buy one. I like my old school 1940s-1980s US iron instead. Nice and simple.
if you pussy foot these engines, direct injection, they fk up. need to use fuel cleaner as well. idi still better.plus if it has butterflies in the inlet, which it will, like bmw ect. take them out,they destroy engines.
It’s really not that bad.
@@TestECull well LS swaps are extremely popular cos of ridiculous engines just like THIS
@@lancecooper4646 And how many LS's have we seen Eric tear down by now that've had catastrophic internal failures due to overcomplication that doesn't serve any practical benefit?
Go older. Carburetted. 350 4-bolt with a massaged Q-Jet and a 268 cam will make roughly the same power with 0.0005% the complexity. And a better sound. And better reliability. And 99.99999% less randomly chucked rods.
I love the constant "oh no", "that's not good", "that's not supposed to go there" 😂
My favorite was ,"I can't tell, something is ungood in here."
Look at the design of the engine.. french cam make better engines, that's not even a fleet engine and they use patines all over that's an engine that will fail sooner or later.
@@ovidiurusu4490 just like the renault diesel which sticking in those a and b from daimler ? real great engines, mister piston headache - such like i those known from the 1990's
It's so weird. I work at Audi and nobody ever mentioned anything to me about the BXA. Water-cooled alternator? That is definitely a FIRST for me. You are teaching me things, and I love every bit of it, good or bad.
the BSM is an higher output in the S8. That what I have.
Some R8 5.0L V10 had a water cooled alternator. I think the Passat 4.0L W8 may have had one. 4.2L Touareg's had them. BMW V8's are fairly common for having them as well.
My 2005.5 B7 Audi S4 4.2L with the Automatic had a water cooled alternator. Beefy sucker. @@corythomas4427
I actually just picked up a 2003 bmw 540i and it has a water cooled alternator too 😂
BAR 4.2 engines also have water cooled Hitachi alternators
The valve train explosion was just what I needed today. It was right out of my play book. Well played.
Correct, These video s never get old
I was sitting here thinking...he took all the bolts out of the cam caps, must not have a lot of pressure on th....hahaha oh shit what a mess🤣
Yeah that one made me bust out laughing. xD
Also known as a RUD. Rapid Unplanned Disassembly.
I agree with this statement.
I sold VW/Audi's when these came out. First, what an amazing engine when you give it some right pedal! Second, what a maintenance and service nightmare. You most definitely do not want to service this thing out of warranty.
What I always was amazed at is when it came to relatively expensive vehicles like this, how hard it was to get people to service/maintain them. Even with free maintenance we had to call and hound owners to bring their vehicles in. Audi had (I can't remember exactly now since it's been many years) either 15,000km or 20,000km oil change intervals, in North America where people do not check their oil ever. On a high output performance engine. Ummm, yeah.
You are correct, almost everything WAS engine out. The service department had motor trays/jigs for lack of a better term - tech would put the car up on the lift, raise engine tray/jig to engine and/or transmission and disconnect everything and just lower it down. They could do it pretty quick on all models since engine out was the norm for most things. Was common to go into the Audi shop of 6 bays and see 4 vehicles engine out. Crazy.
And that uber complicated timing system with the A/C running off of it. Just imagine the shock to the system every time that cycled on.
The noise this thing must have made as it blew up surely echo'd off buildings for blocks.
So, what did I learn after working for Audi/VW for years? Never ever own one of these things out of warranty.
You got that right, about outta warranty ownership. It’d cost a small fortune to go thru the timing system and replace everything. Typically why people off them right before or soon after off warranty. Let someone else deal with the inevitable. Now on the flip side, to someone like me who has the facilities and capabilities to work on them, they have their place and can often be picked up cheap enough in very nice condition with the presumption of going thru and fixing/replacing alot of high dollar stuff right of the bat as preventative maintenance. That is when the price is sooo right you just basically budget that into what your not spending on buying the car itself.
regarding the a/c - they use a continuously variable displacement unit that doesnt switch on and off. Even Golfs (mk5 and newer) have this.
@@robertmason8341 Complexity of this design makes the average BMW engine look simple! This could be the poster child for German engineering run amok. Also explains how the resale value of German luxury / performance models sinks so low as they age. The third or fourth owner thinks they are getting a deal on a great ride. Then they learn how expensive it is to maintain correctly. Sooner or later something breaks and the engine has to come out to fix it. Now they know why a used Camry cost twice what their same-year used Audi cost!!!
@@billyjoejimbob56 If you got one of those cars for free plus $10,000 cash, you’ll be in the hole in one year.
@@alskooper3319 Guaranteed money pit!
Damn that timing system looks like a steampunk convention.
Indeed!
@@lizkrinsky5209 The 97-10 Ford Explorer had a german Cologne SOHC engine that had rear chains.
@@alb12345672 And no timing marks to make it easier to work on,lol
@@KRRZ350 Just guesstimate :lol:
Ya, hay-soos.
I do notice though that while he criticizes Mazda's MZR 4s for having a single-row timing chain, this V10 has several of those, and it's driving 6 more cylinders putting out 2X more power.
As an industrial electrician, I found out that if a panel won't come off when you remove the bolts, replace the bolts even if loosely. Because the next panel is trapping the first panel. Which is eager to jump into the buss bar and the nearest ground
That failure mode does not sound desirable either 😅
I'm more appalled at the design of the engine than I am at the damage done to it
Overhead cam engines are always so complex with lots of potential breaking points.
It's honestly not that complex. I'm very familiar with them. The actual internals of most Audi engines are very strong. The components around the engine... not so much. The 4.2 v8 engine in the RS4, for example, has a closed-deck block with a ton of reinforcements, forged pistons, forged connecting rods, and a forged crankshaft. It can handle an incredible amount of abuse. This V10 is also very tough. I'm not sure how this one met its end, but most likely, it wasn't maintained properly. My Audi engine has over 120k miles on it, and the internals look brand new. There's not a single stain or varnish on anything. I've had a ton of issues with everything surrounding it, but not the engine itself.
@@ejkk9513 I used to own a 2005.5 Audi S4 with the 6-Speed Auto and loved that 4.2L V8. First thing I did after buying it, was swap out those junk plastic timing chain guides for the metal RS4 guides/tensioners. I ran it from 98k miles to 127k miles with zero issues, until one day it was 15 degrees below zero and the coolant reservoir broke in two spots pretty much draining the engine of coolant... had to get her towed somewhere and she got stolen :/ Yea, it sucks. Smoothest engine I have ever felt, the V10 is probably even better!
@ftffighter The coolant reservoir in all Audi and Volkswagen cars are designed to fail. I have replaced them on every single car that is over 10 years old. Like I said, internals are strong. Everything surrounding it is crap. Purposely so. I've driven a Lamborghini Gallardo with the 5.2L V10, and it sounds lovely. It's actually not that smooth because it's a V10. This design is inherently prone to vibration. It has problems with primary balance, and it has an uneven firing order. A V10 has to have a V angle of 72 degrees to have an even firing order, and this V10 has a 90-degree angle without a split crank journal. Audi uses a balance shaft to counter the balance issues though. The Lexus LFA is the best balanced V10 ever made. The 72-degree angle used is perfect. I love the sound of most V10 engines, but on an engineering level, they have some serious challenges.
@@ejkk9513 Yea, I definitely figured that out the hard way. Breaking at both ends of the reservoir at once was pretty bizarre. The cooling systems rely on plastic couplings, not metal, in order to "Expand" properly under heavy loads. The worst part is, if you do end up using metal on one piece, it'll just add more pressure to the other plastic places. Which means you ideally have to replace all the joints with metal or you're stuck with using plastic still. Not to mention, aftermarket isn't the greatest so if you used metal you'd have to manufacture the parts yourself. Not sure if that would cause anymore failure points do to improper expansion of the system too. So, you're kind of stuck with plastic. The plastic does seem to work well as long as it's maintained properly and the pieces are all checked ahead of time for cracks and failure points due to long-term wear and tear however, so it's not like it wasn't engineered well. The design is fairly solid and kind of cool when you dig into it, but you are right though... the plastic is designed to fail long term. Don't get me wrong, you CAN bulletproof these engines/cars in the end. It just depends on how much you umm... "Love your car" per say XD.
This was probably one of THE BEST teardowns I've seen on this channel yet. Just based on the complexity of this Audi engine and the sheer and utter carnage inside the block was a sight to see. And yes, the valve train "explosion" was epic!!! This channel keeps getting better and better. Well done and keep the carnage coming my friend.
Yep, enjoyed this one almost as much as the Miata teardowns
That was an impressive teardown! This engine is another monument to unrepairability. I wonder why they aren't welded together on the assembly line. At least we would know the truth. I don't recall that you've ever torn down a W8 or a W12. They are even more complicated throw-away engines than the V10. Thanks for my weekly fix. You have a great channel. It never gets old.
Hoooboy I almost bought a B5.5 Passat W8 new. Glad I set my sights lower and ended up with the 1.8T, but that W8 6-speed was a blast to drive.
@@geeniusatwrok w8's probably amazing until time for the belts...
2 kinds of audi/Volkswagen cars, broken, or losing value so fast they aren't worth fixing.
Believe it or not, these engines get repaired over here, they are to expensive to replace, so the vehicles get often scrapped and engines repaired to second hand owners
I honestly think I get more excited for these videos to come out than any other youtuber I watch. I love this channel, I see you hitting a million subs sooner than later.
I love the sound the air impact makes when it's sped up, it sounds like a blaster from some kind of sci fi movie.
🔫 Pew Pew ! Cracks me up every time too. It's the little things in life.
Someone on a SRT forum tried to convince me that Audi engines are very simple and easy to work on.
I almost died laughing so hard !
It always blows my mind to see how complex these VAG engines get. Makes the LS look all the more genius every time you pull these crazy things apart
Ya, if we Americans do complex engine stuff that requires engine-out and/or transmission-off it's usually to cut corners and graft new tech onto old engines.
"Vag" engine is RIGHT...
3 cheers for pushrods
@@ramenbo 🍻 for cheers...
Imagine you had to work on one of these in a vehicle!
Awful
It took longer than I'd like to admit to realize the timing chains were on the rear of the Audi engines when I first saw the pictures online.
I think part of it was disbelief that a modern-ish design could be that terrible.
Timingchains on the Mercedes 220CDI engines are at the back too
It is not that uncommon, why in that world they do it like that is a mystery thou..
BMW also put timing chains on the back end on some of their engines. The N47 diesel (used on numerous different models) is infamous for chewing up timing chains and destroying the engine at quite low miles, even if you caught it in time it is a big job to repair with multiple chains at the back.
Ford's 4.0
@@GodiHateOtakus Ford's SOHC 4.0 was an effort to modernize a pushrod engine and convert it to an overhead cam engine. So there's a jackshaft where the cam used to be, connecting the front half of the timing chain setup to the back. Maybe so the cylinder heads are still the same side-to-side? Idk. Terrible design, terrible idea. Also, based on the Cologne v6. A German engine. Lol
My dad sold his to a tweak when his s4s chains went...tweak assembled a sort of chain and pulley system in the apartment parking lot and had the chains replaced on his own through the night.
The more of these videos that I watch the more I appreciate the engineering in an old Chevy 350!
More like lack there of
@@charliep4680Exactly, less crap to break.
OR an LS 🔥😛
@@xtremeboost7 Also much less efficient. Lets not pretend like every sbc is a 500hp street machine when they came with 250 on a good day from the factory
@@charliep4680 i have old magazines that have articles showing just how good the small block Chevy v8 is: brake specific fuel consumption figures of 0.38. Very few modern engines can achieve this. Diesel engines can deliver better numbers (lower, down to 0.30), but high oxides of nitrogen pollution is the result. Not so with the highly efficient small block Chevy.
Bang went my interest in any V8/V10 Audi! I swore off Audis after the parts cost on an Audi 4000 Quattro back in the late 80s/early 90s. Any hankering left is now gone! Superb video -- thx!
I remember going to Chick Iverson Porsche/Audi in Newport Beach around 1987 and looking at an Audi Quattro. I couldn’t believe the price tag on it, not too far from a 911. To me it looked so cheap with so much plastic bodywork.
I replaced the A/C compressor with the engine still in the car in my 2007 Audi S8 which uses this same engine. I assume it has marginally more space than the S6 does to work but it was still a bear to do. Front bumper has to come off along with the condenser and the radiator along with the thermostat. Once there, you have to remove the driver's side engine mount and then you can work the shaft driven compressor out. I did this in the driveway and took the whole damn day but saved me tons of money.
I can't speak for all subscribers but because you are probably the only person I know that would go to the trouble to verify the burnt Miata engine runs is why we are subscribers.
Yup. I agree
I’m a heavy duty diesel tech and I’ve seen so much carnage on big diesels from blocks with windows to broken cranks and everything in between. I just found your channel you’ve got a new sub. Kinda wish I filmed some of the stuff I’ve seen.
If people really had any idea what mechanically speaking was rolling down the road with 40+ tons behind it, they would drive more carefully and give trucks more space.
Poured myself a LARGE, boozy eggnog drink to celebrate the holidays, lit a fire, and settled in for 57+ minutes of the most entertaining thing on the web - you did not disappoint. Thank you!
Yep. I'm crocheting Christmas gifts while I watch along with some custard nog... sip, double crochet, glad I'm a Toyota girl, chain 3, single crochet, yikes, that made some noise, sip, chain three... holy schnikey what a mess... piston McCrumbs.
Yep... Toyotas and Hondas for me... never had less than 248,000 on any of them and they still ran like tops when I got rid of them... and always do my services and regular oil changes. A weekly reminder on why wee do those things... or deal with malice in the palace.
I've been binge watching these... Normally I see a video that's 45-60 minutes, and I think "who has time for that?" I will watch 3 or 4 of these in a row... no problem. Also, I just realized something during this video... no swearing... not even a "beeped" cuss word. Sometimes it can be funny, but in your video's it's refreshing. I've never laughed so hard while learning. Keep up the great work.
the completely disintegrated piston coming into view was almost like a horror movie. The sheer amount of carnage!
It's rather mind blowing to imagine the forces involved here to turn forged steel parts into confetti...
That`s 450 horsepower at play. Well a little less since its a s6 not s8 engine but still a LOT of power
@@Nordic_Mechanicsome quick math given the stroke and 7000rpm redline of this engine reveals that the pistons are experiencing 20,263m/s2 of acceleration, or 2067Gs. Say the piston weighs 0.25kg (around half a pound). At 7000rpm that same piston has the effective force of 516kg (1,137lbs). That’s if it broke on a non-ignition stroke. If it broke during an ignition, then as you said, you have 435hp on top of that half ton of force.
Somebody sent it for sure😂😂
This is hands down the best teardown video I watched on RUclips. I have to wonder if this was a "money shift" that overrevved it enough to cause this kind of wreckage. But the amount of sludge and varnish in the oil pan suggest lots of deferred maintenance as well.
How does one money shift an auto
@@kyleshehadi4119drop it down 4 gears lol
I really appreciate that when my 5 year old wants to watch I don't have to worry about what you will be saying. Thank for the great content!
what a moron which try to moralize otherones ?
nothing knew in the east ?
Easily the most entertaining/satisfying teardown you’ve done so far. The rapid pace and transition from suspense to comedy was worthy of the best Warner Brothers cartoons. The quick progression to ever-larger BFHs (6:50) was Bugs vs. Yosemite Sam level great. Chuck Jones would be proud! The Jack-in-the-box cam gear surprise (21:14) was also a high point. The final camera shake from scattering engine parts hitting the tripod (21:19) was a deft comedic touch. Now when people ask me what “double overhead cams” means I can just show them this clip.
with cam cradle/plate explosions like this, unexpectedly, is why we wear eye protection and/or face shields kids 😂
It’s amazing the engineering that goes into some of these engines. Some of the castings that you find are intricate. I’ll stick with the push rod engine.
They should have saved rocket engineering for rockets. It is unnecessary complicated.
The sheer amount of engineering gone into this is deeply insane. With the EV changeover in full swing I can't see too many newcomers willing to learn all this. Thanks hugely for such great information presented so nicely, could watch such stuff all day.
Yeah, the people who will still have such (unnecessarily) complex engines in "historic" cars a couple decades into the future are going to be paying absolute fortunes for servicing...
All the crazy engineering for what - no help in passing upcoming emissions targets.
@@HenrySomeoneMeh, I mean that's somewhat true but not really. Service costs will go up, yes, but ICE cars worldwide won't be considered "historics" in such a short timeline, eventually EVs are going to reach a steady market equilibrium with ICE cars and by that time the benefits of EV transport on such a scale would likely have significantly cut emissions in an optimistic scenario, so why litigate away the remaining ICE cars or expect them to be so cost prohibitive (compared to any car) to own?
@@coliimusic I wasn't talking about ICE engines in general, but specific, high-end and very complex ones like this V10.
take a look at the older large piston engines before the jet turbine engine replaced them in aircraft
That rube-goldberg timing system was hilarious.
Thought the exact same thin😎
I know you spent a whole lot more than 57 minutes making this video but well I sure enjoyed the 57 minutes of watching it, thank you
The timing chains on the back (and a lot of the rest of the design) make a lot more sense if you consider this engine in the R8. In a mid engine car, the front will be against the firewall and the back will be more open, usually they have a small access panel in the car's interior to have access to service belts. Audi taking this and slapping it in a sedan equals service nightmares/engine-out for everything, I'm sure the fancier and more expensive sports car is actually a lot easier to work on, ironically.
First = The owner of these cars in germany have an better level of money ...
Secound = The car mechanic for these performnce Audi / Lamorghini are skilled (plus 3 years standart car mechanic school . Every german car mechanic passed these 3 years car mechanic school 2 days a week and 3 day at the car garage) .
BUT a car mechanic for these AUDI is adittional trained some days/week at a special AUDI school to service + repair these performance car.
Third = I think the Audi (and no name garage) know that is is normal to build the engine out of the ...
Even if he spend one day for these work plus one day to fit it under the engine compartment.
For difficult work it is easy and he can do a better work.
Remember the owner is person with higher incoming and is able (and will) pay a lot of money. The owner know these.
These is a performance engine in an performance car for sales man. He will use the abillity to drive unimited speed level at these parts at the german Autobahn with no speed limit. And the owner is able to pay the premium 98 ROZ (normal he drive to shell with 100 ROZ or ARAL petrol station with 102 ROZ). The highest prize petrol is good enough for him. I think in US you can not get these quality petrol. In germany you can get these at ervery petrol stations and at Shell or ARAL petrol station these top level petrol. By the way thise is not a special raceing petrol.
The owner is able to drive with these car 200 mph at german Autobahn.
A lot of owner say = well 155 mph is enough for me.
An Audi R8 V10 is a sport car. These engine you find in a bigger size Audi RS6. You drive with you wife and family shopping.
Enough space for the shopping and the children. And use these car for your daily long distance was to your customer as a premium sales man for big companys.
Service nightmare for the car mechanic = yes
The owner know the amount of money and can afford it.
The Audi garage know these and say ok we will sell these service nightmare. We have a skilled trained car mechanic with addition AUDI school training.
If you are not a trained AUDI mechanic leave your fingers away.
If you are not a Space ship mechanic you leave normally you fingers out of an space ship aswell.
If you are only able to service a american V8 well and ok. No problem for me.
By the way I never ever but my fingers in these Audi V10 or Mercedes perfomance engines (or BMW performance) because I dont like these engines. But if my boss send me to these special traing schools for these performance cars ...
Well then I really like to work with these engines. My boss will buy all the nice tools for that car. Enough working place and enough time to work. And a computer with direct access to the car manufacturer plus telephone hotline to constuction engineers.
Only fighter jets and Space crafts mechanics are better ....
These car mechanic are toplevel trained ...
If a low budget garage or an unskilled garage owner is the boss of the car mechanic ... well
When I am a owner of a Audi V10 engine and I go to a Yugo garage ... 🙃
@@callishandy8133 well stated.
In 2003 Audi came out with the B6 S4 4.2l and I believe that engine was the first to have the timing chains in the back. I read that they did this because of packaging issues. This looks to be about the same setup. It's unfortunate they had to go this route because the 4.2l timing belt motor I read is supposedly a boom proof motor. I bought a S4 with a 4.2l in it. It had a new engine form Audi installed. The bill was over 30k for that new engine and install.
I don't believe that is correct. IIRC the Lambo and the R8 have the engine flipped backwards in the car so that the transmission sits in between the seats. This means that in the car, the timing chains are still up against the firewall.
@@callishandy8133 Our (US) 93 octane fuel is 98 RON. That's about the highest octane we generally see at a mass-market gas station. Most states carry that, though some states sell 91 octane as their premium fuel.
"Strategery" (0:08) is my new favourite word. 😁
This failure would've been one heck of an event to witness. Super interesting disassembly with great commentary. Great channel. I'm hooked :)
Looks like it literally detonated. High energy failure indeed.
Really makes you appreciate the LS's simplicity compared to this. Opening the timing cover looked like looking inside a Rolex watch...
I had the same thought, absolutely ridiculous
Nah, judging by that "This $25,000 Rolex Explorer Was Exposed to Seawater" video (ruclips.net/video/xasm3GFL7mM/видео.html) the innards of Rolex are somewhat neater ;-)
Indeed a work of art. Also as a mechanic once you learn how to work on these engines how to do the timing it’s like opening a new level of knowledge in your brain. Really sets you apart from other mechanics.
@@Angelo80907 _Indeed a work of art_ - yes, but then there's this German ironic saying "warum einfach wenn's auch kompliziert geht", or "why make [it] simple when you can make it complicated"... ;-)
@@MrKotBonifacy 🤣 damn show offs
Wow! I'm not much for the German varietals, but this is a rare treat indeed!
Decently reliable for what it is, and I am a huge fan of the concept of stratified fuel injection. The only issue, of course, is dealing with the carbon buildup that is a problem on all direct injected engines (a problem with a solution that I love: simply add another set of injectors in the ports). From the moment I saw the mechanical re-gapping and the amount of buildup in the ports and on the plugs, I suspected a typical third-owner 'run it until it breaks' mindset. Green coolant, worm gear hose clamps, and varnish buildup tell me that it wasn't professionally maintained, which means that there is a decent reason that the S6 loses 75% of its value after just ten years.
German complexity and a lack of reliable aftermarket, coupled with not a lot of shared parts with their 'lower' offerings means that these engines are destined either for destruction or overly-expensive maintenance. The number of times I've heard something along the lines of "just because I drive an Audi doesn't mean I have Audi money" on a five-year plus old model is both heartbreaking and infuriating. So, I tell people the prices and have them yell at me, then go about my merry day selling VVT solenoids for GM LAF/LEA 2.4s.

Toyota did add injectors to the ports along with their direct injection. works well.
The biggest thing is people don’t realize that just because the car was 20k to buy used doesn’t mean the parts are gonna be for a 20k car. There still priced at the new 80k price.
Slant six would be boring..its about 30 pieces and none will be bad.
VAG has used dual injection on their European market cars for quite a while, likely even before Toyota. Obviously with US market being skewed towards lower price point, all we've got here was flashy big rims. Priorities;)

They look happy, except the one on the end that had it’s face busted into pieces.
Highly entertaining teardown, thanks.
I've seen far worse "shrapnel" and Involuntary Self-Disassembly Products in my days working for a race engine company. Including an F1 piston that let go at 18000rpm, after which no piece of it was larger than a pea.
Usually I was in the design office, but visited the engine build / rebuild workshops regularly.
On one memorable occasion, an 800hp 3.8litre V12 had broken a rod at 12,000rpm, destroying the cylinder bore and breaking the block. It was bleeding fluids on a build stand, awaiting teardown.
As I took a closer look, some education expert was giving her opinion on the radio: "The word "failure" must be banned!" she adamantly insisted. "There is no failure, there is only 'delayed success'."
Ignoring what she was trying to say (about avoiding being negative regarding any child's future development, and encouraging them to keep trying instead, except she had not clarified that context), I looked at the guys at their workbenches and said, "In that case, I look forward to this engine's delayed success..."
Seeing the (relatively minor!) devastation of this engine reminded me of that moment when an engine failure became an engine's delayed success.
Best passive aggressive comment ever
Here in Germany, everyone knows that especially this engine is scrap! It has nothing to do with the lambo engines, a lot of people thinking. There was a technical service information changing oil and intervalls. Despite of this, the coating of the cylinder walls are short lasting.
A lot of praise need to be given the engine block here.
The amount of destruction coming from the one pulverize piston and rod would normally escaped out of most engine blocks but this one kept everything inside.
Emailed the sales people about the recent LT-1 teardown and got a great price and quick reply but remembered where I live at the moment and that shipping would be more expensive than what the engine costs. When I make it back to Tennessee, I'll be doing some business with your company
The complexity of this engine is just amazing to see.
Thats what it take to run 170 mph all day on the Autobahn.
For how long?
@@quicksilver462 do you live in Germany?
You had me at the first "Oh oh!". The complexity of the engine and engineering involved is pretty amazing. Never knew they water cooled the alternator. What I'm trying to imagine is the sound of the engine tearing itself apart. Assuming, as you said, it was a high RPM failure, that V10 instantly became a V8 metal grinding machine. Eight cylinders still firing with good plugs turning the crank and beating the out of the one that failed. Wonder how long it kept running. Thanks for a most enjoyable tear-down. Take care.
"Whatever it was, it's a T30 now!" Love it!
OMG, 21:13 is the detonation-mark! One screwdriver, one small poke...SPROING! I actually LoL'd IRL at that.
I am so glad that you upload videos of these expensive engines cause I have learned from your videos to simply walk away from buying any of these european brands of cars & suv's.
Your videos always help me keep my feet on the ground whenever buying a new vehicle cause I know what brands to walk away from.
My 2021 Chevy Silverado 5.3 engine lasted 11,000 miles. Lifter failures and bent pushrods, Just saying. My Audi has 110,000 miles and purrs. Every major company has built a cluncker or two.
@@markhoward9355 My 2004 Silverado pushing 200k . Not bad for a $400 truck, but it is getting ugly.
@@alribee For sure, I love hearing of high mileage, long lasting trucks. Don't think the "rules" of yesteryear apply anymore. European vehicles are thought unreliable because they are overly complicated and computer controls. American vehicles are unreliable because they are built so freakin cheaply.
Thank you for the video.
Obviously, the Rube Goldberg force is strong amongst Audi engineers.
All German car engineers belong to the church of Rube Goldberg. I’ve always wondered is the needless complexity an engineer’s “flex” or is it an attempt to keep all the labor money with the dealers. Pull the engine or pull the trans to work on it in the car…and that would still suck all up under a lift and the transmission tunnel exhaust etc obscuring your view/access. WTF, I can’t think of a single good reason to put the timing chains on the back side of the engine unless it’s got to do with Quattros and engine mounting would be crazy forward/hood length suspension. Probably just answered my own question 🤦♂️🤣
Rube Goldberg came immediately to mind as he tore into this monstrosity. German engineering at its finest. Why keep it simple when it can be designed overly complicated to show how smart the engineers are?
I have to say this was a great teardown. Thanks Eric. Id love to see the 4.2 sometime.
You attacked that stuck bolt in the socket exactly as I would have. Thumbs up!!!
Great teardown. Can't imagine the bang this spontaneous disassembly would have been, would make a great ringtone.
I wonder if the owner realized this was a gonna, and just kept going as there was nothing to lose.
I remember a lady pulling up to a country service station, and asking for help, it made a big bang and was running very rough. Inspection found a rod hanging out of the block. Advice to the lady, yeah try and drive home, nothing to loose, your going to need a new engine.
If someone had told me that I was going to spend almost an ENTIRE Sunday watching a discount Adam Sandler tear apart some really trashed engines and make dad jokes, I probably would have laughed. BUT, that is exactly what I did. These videos are like eyeball crack, I can't stop watching them. I'm not a big car guy at all, so I'm actually learning a lot from watching you tear these catastrophes down. It's very informative and the sound of breaking those bolts loose is like audio heroin (why am I making so many drug jokes?). I can't get enough of it. You are extremely knowledgeable, but you also aren't afraid to admit, "I don't know what I'm doing." To be honest, I usually don't watch videos that are longer than 25-30 minutes because I'm lazy (and at 50 years old, my attention span seems to be diminishing), but I click on yours without ever checking the run time because they're so interesting and enjoyable. I'm hooked and look forward to working my way back through your video catalog. Well done!
That is one overly complicated engine with probably double the failure points and 5 times the cost of a standard LS engine. It looks like it was over revved and sent a piston into the head. While the broken rod hammered everything! You are getting damn good infront of the camera. Keep up the good work!
I think the rod broke. If the piston came apart first, that wrist pin would've been flailing around and had much more damage to it.
@@alro2434 It could be too given the condition of the wrist pin, your right. That means the rod bolts let go looking at the condition of the rod & what's left of the bolts & after that the crank schreaded the parts in the destruction. I thought it was piston failure but thinking about it that could still be the case though looking at the rubbish design of them. The piston in my vehicle that failed had a design like these, no whole piston, just a half piston with skirts, well it was the skirt that broke off on mine which very nearly had the piston turn sideways in the bore, thankfully that didn't happen & only bore scoring happened. a rebore & new aftermarket pistons (whole ones) and she's still driving around 27 years later. Anyway there's a couple of theories.
I thought that too but it was fitted to an auto gearbox so it should no be able to be over reved, i am rooting for a rod failure given how skinny they are.
Rocker arm failure. They designed them with too small roller bearings that eventually fall out… carnage ensues.
Ah, the bolts stuck in the socket. If they haven't snapped off, I usually thread them back in the hole to get some leverage to pry the socket off.
If they do snap off, I throw them down at at concrete surface. That usually pops them out after a toss or three.
I also had to do that to liberate a tophat from a loaded Macpherson strut once; that was an adventure.
This is a great channel. I didn't even know I wanted to watch an engine teardown, but here I am on number 3 in a row. You keep it interesting and funny, both with your comments and your edits, and you don't have any of the super annoying crap you see on most channels. Keep up the great work. Subbed and shared.
I've watch three V10 teardowns in a row, the magnum 8.0L, the Viper V10, and this one. And I've noticed a common theme, they eat pistons regularly.
The sound when this let go must have been epic. Thanks for the vid. As ever, really enjoyed it
I can attest the V8 4.2L variant is the best sounding V8 I’ve ever driven. It’s as if an American small block with anger issues went to college in Germany. They’re insanely good until they have any problems 😂
Given those engines make ~500hp at ~8,000rpm the detonation might have been immense!
I think this was the best teardown I've seen on this channel yet! It definitely confirmed my feeling that I will try to NEVER mess with any of these ridiculous Audi engines, and the humor quotient was high. "Something is UNgood in there" had me laughing.
I had one of those in a $500 s8. A transmission position sensor replacement was to much to keep it alive so I sold it for $500 after almost 2 years of ripping it.
I see several other parts could had caused similar decisions. That car was a blast but to low to actually drive in snow.
So what this video tells me is that being an Audi mechanic is very profitable. When the design team asked how many single points of failure they should include management said :"how many can you fit in an engine bay?"
All this complexity and money gets you 5.2 V-10 602 horsepower and 413 lb-ft of torque
As a mechanic & someone that has made various contraptions over the years ,it grieves me to see the lack of respect & gratitude some owners have for their machinery , the amount of work & effort it took to create that thing & someone can't even keep the oil clean , I reckon we should form some sort of justice for machines club & go around & bash up people who mistreat their engines !!
I agree dude but unfortunately that would be over half of the population of the world!!!!!so many people buy these beautifully engineered vehicles and only take them to a garage when the break!! And not for servicing, I have been a mechanic 4 30 years and it still amazes me how badly people treat there vehicles and call them pieces of shit when they break down!!!! When they never have any maintenance done to them CRAZY
@@SimonHarvey-i4zit’s a half of the population because half of us are women, this looks like a failure due to lack of maintenance. The female driver probably heard some “bad” sounds but thought, it’s more important to get the shopping haul home than to stop. That’s the thing with these v8-v12 complex machines, they can loose a whole cylinder or 2, even three and still get a stupid person home, a simple 4 cylinder would stop immediately and limit damage.
That is by far the most devastated motor Ive ever seen that could still be turned over manually with no problem.😁
xaxol eto peremoga?🐽🤣
There’s a guy in India that can work miracles on that engine block, he might can even straighten out that bent rod.
With Ramen Noodles.
@@TwentytenS4B8 no doubt
Eric you’re a better man than I. So many words would have said at 21:31 when that cam plate flew off!
Don’t worry I said them for him😂
Remember, he has small children....
This one was one of the most interesting and satisfying to watch because it was so incredibly complex, so strange! Water cooled alternator? Long, open shaft drive? But the real kick was at the end, seeing the incredible damage from an over-wound, never-maintained engine! Makes me want to change my oil and keep the revs down. The memory of this one will stay a long time. THANKS!
My 2007 Honda Element SC is 16 yr old it has a small 2.4 Engine, stickshift (manual) and yet its still running strong with almost 150,000 k miles, NEVER gave me any problem except for its normal wear and tear parts ... just break pads and clutch. Its well maintained and everytime i drive it still puts smile on my face, pull strong like the first day. I never had the urge to buy a more "powerful" V8. My 2014 NA V6 Accord Coupe stock has plenty full of power (almost 300 hp )...enough for my daily drive, 2021 Civic Type R and 2015 Mitsubishi Evo X FE on the weekends and both have 2.0 turbo engine. Never have any engine problem and that's all i need, a small efficient but strong robust engine. My family and friends have V8 cars but they spend more time in repair shop. I talked to a lot of mechanics and majority of them told me Rated R type horror stories, scared me for life lol.
how to reduce the lifecycle of an engine ?
build it whith aluminium > daimler 6-cylinder from 1,8 million miles to following well known word:
_" we hope you enjoy the guarantee "_
I have been waiting a long time for this engine to be on the channel! Thank you!
Tip to get a stuck bolt out of a socket, just throw it at the ground slightly hard lol works for me most the time just be sure you do it where you can keep track of where the socket goes
I just thread it back in and wiggle or tap it lightly. Engage the threads, use your heads.
I've said this on each of the last few videos, but they really do just keep getting better and better. I bet all that over-engineered complexity seems great until it explodes into massive carnage.
I own a D3 S8 with the same engine, and i have never seen or heard of a car with such constant problems, genuinely a marvel of engineering.
A marvel of engineering garbage..buy a ferrari
That was, by far, the best dohc extraction EVER...! Thanks, keep up your awesomeness and go enjoy some nature today...!
i said i would love to see higher hp performance or modified engines and you delivered.
That was a decent blow up, for sure... That had to make some serious noise... Love the channel, keep up the Great work...
When are you going to embrace the idea of utilizing the forklift to remove the dipstick?
YES
New to the channel and dig it. As a tech, I enjoy getting "helpful hints" on the new ways automotive engineers show their love for the average technician... Lol
Useful tip, spray a little PUB-BLASTER or WD40 in the socket before you get into really rusty or greasy areas. And don't beat up the defenseless socket. It was just doing it's job, a job YOU put it in, btw!!
Jus messin with ya, but use the tip, it works. Have a pleasant day!
Fourth owner syndrome in effect.
The First owner - Gets maintenance done at the dealer, only uses OEM parts, books car in for oil changes 500-1000miles before it's due.
The Second owner - Gets maintenance done at a local garage, uses good aftermarket parts, changes oil on schedule.
The Third owner - Does maintenance themselves, uses the best parts they can afford, changes oil within 1000 miles of schedule.
The Fourth owner - Can't afford to do the maintenance, bodges fixes out of RTV & jubilee clips, adds oil only when the light on the dash comes on.
The Fifth owner - a guy named Eric, who tears it apart to entertain & educate the rest of us...
Thank you for your time into making these videos. This one was exceptionally hilarious and interesting. Suggestion: you should keep the surviving wrist pins that go through the piston McNuggetfication process from each tear down to sell as channel merch.
Must say this has been my favorite video so far. The lack of external damage compared to internal damage was impressive.
That was the best oops you’ve ever had.
And that mess behind the timing chain cover reminds me of the complexity of a moon phase watch with all the gears visible.
So satisfying to watch these engine autopsies. Gives me a great appreciation for the sophisticated and complex engineering and manufacturing. Seems like they ought to cost 3 times what they do cost. This also makes me appreciate the two relatively simple electric motors that provide my Tesla with a silent and instantaneous 670 hp.
Your tear-downs are great!
I’m repeatedly amazed at the overkill built into engines like this one.
Fully convinced, as if I need any more convincing, that I won’t ever have an Audi, VW, British Leyland, or many other brands.
Great video! Thanks!!
17:23 when that timing system was shown, F THAT, definition of overly complex.
I really enjoyed this one. Thanks for the effort you put into making these videos:)
0:49 the Audi 5.2L V10 is based on the 4.2L V8; they have the same bore spacing. The original 5.0L Gallardo V10 was a different design that had its genesis in a couple of concepts Lamborghini built in 1988 and 1995; that engine has a bore spacing of 88 mm. The 5.0L V10 also used port injection as opposed to the DI used on this engine. Interestingly, the S6 and S8 versions use a split pin crank, whereas the Lamborghini (and R8) versions use a common pin crank.
8:20 I feel bad for anyone who ever had/has to pay for A/C compressor or power steering pump replacements on these; either one is an engine out service IIRC.
8:56 an...absolute unit?
Kind of recent ford Explorers used a German Engine with very similar setup, rear chains.
@@alb12345672 yeah, the old 4.0L V6 (or as I call it, the Cologne codger). It was a converted OHV design. Real piece of crap, that one.
@@CaptainSpadaro The original 4.0 OHV is a great motor, anything can be fixed easily in the car with basic tools. My 96 Explorer still runs like new with it. SOHC one :lol:
@@alb12345672 The SOHC one is the one I referring to.
Audi Manager: How do we really piss people off?
Audi Engineer: Let's make several unnecessary points of failure, require a 84mm socket to change the oil filter, impossible to mount without a special mount from us and we will charge 10x the normal price, and everything will require a torx bit.
Repurpose your engine hoist as a dipstick remover! Fixed it…. =)
yo true, just use the forklift
You needed the safety tote when taking out the cam carriers lol This reminded me of a blown up Top Fuel dragster engine---everything inside turned to shrapnel. I don't think I've ever seen a cylinder bore that hammered before, it looked like a bomb went off in there
I like the idea of a water cooled alternator. My off road truck goes through alternators as I often do deep muddy water crossings. The brushes wear out very fast. I've been thinking that an alt like that one wouldn't have that issue.
Ask a BMW owner how they like their water cooled alternators.
My old bmw 323i alternator lasted 250k miles before it wore out. On those cars they had a air duct to blow cool air on it.
@@philrab Yes I had an X5 with one and it leaked slowly for 3 years, over $1,000 to replace it so it stayed that way. Although for an off road non BMW application that runs the coolant at reasonable temp a sealed water cooled alternator it a good idea, especially as no one ever buys used ones, you can get a good one on the cheap I a sure.
Crazily built engine. Definetly exotic. No main bearing caps; uses a "bed plate." Looks way stronger than individual caps. And no worries about that flex plate coming loose! Quite the circle of fasteners.
That motor is so complex, I can't see it being a long term, reliable engine.
You have skills and good humor and we enjoy when you drag out BIG BLUE. Your facility pictures are impressive, that is a big brick structure you got brother. Thank you for sharing what you do to the world. May you have many years more sharing and selling car/truck stuff.
I bet that made some amazing noises when it blew
Yeh, these german overengineered engines are some pieces of...well too much overcomplexity.. But those dipstick fights are epic, man! Keep 'em coming! :)
Those cam phasers are worth a ton of money
Absolutely incredible- the engineering is amazing - the engineer that put this together had to be in the diesel industry- crazy motor!!
Being able to zoom in in 4k is so satisfying.
Again a closer look at the rod could have been interesting.
The way the rod cap was stretched, is what i would expect if one rod bolt was lost.
Would be nice to see if one of the bolts was snapped, or was stripped.
Is suspect this *could* be an over-rev failure.
If I'm not wrong, they are only automatic gb, so I'm not sure that you can over rev these 🙃
@@James-rf5xd You shouldn't be able to over-rev it to the point where the rods lets go either way, but systems fail, and sometimes allows things it shouldn't.
VERY good sleuthing. Are you an engineer? I noticed the same thing. ONE bolt came out. The other did not, the rod cap stretched. Why? Not bearing failure.
Dipstick tubes have always been my arch nemesis also. Not that I like to see you struggle, but it does make me feel better about myself.
I've seen some messed up shit over the years but a conrod blasted to pieces.. that's something special. At the same time valves were actually intact, I've had a similar case with a 1.8 TFSI, one piston blasted into oblivion and cylinder walls cracked (bear in mind that's an iron block) but the crankshaft was perfectly fine.. funny how sometimes parts survive miraculously even though the rest of the engine was sent into the 4th dimension 🙂
Having had an Audi 4.2 V8 from 2000, I was very interested in seeing thus teardown. Never had any problems with mine over 160k miles, but regular maintenance wasn't cheap.
My first thought was hydraulically locked after showing off driving through water, but at the end, I'm thinking probably over revving whilst drag racing. My father always instilled into me; never exceed 85% revs, cruise at maximum 60%, sounds dull these days, but very kindly on the wallet!
forget these engines: they came from mussolini and vendettas are there the normal state.
take a look at the supercars - you will find this one again
Very cool to watch this tear down. Thank you for taking the time to video all this engine pron.
Would you sell unusable parts as channel merch? I would absolutely buy a piston or something lol
