I am actually impressed at the simplicity and robustness of the design. Large bearings, simple timing chain setups (that seem to hold up well for 150k), and no crazy fasteners!!
I do like the simplicity of Hyundai/kia engines. There tends to be more space in the engine bay for working. Seems fairly rare on new vehicles these days.
As the current owner of a 2011 4.6 genesis sedan, I had no choice but to join in for this video. Just turned over 150k miles yesterday and still going strong. Holy crap, I immediately went to write this comment as soon as I opened the video and am returning shortly after to laugh at how this engine is from a 2011 genesis with 150k on it 😂💀
Right? Read this comment after hearing it in the video and couldn't help but raise an eyebrow. Hopefully yours gives you many more miles of trouble free motoring. From what I've seen in this video alone (admittedly not a wealth of experience) they seem to be good engines.
@@_supasped_ I’ve had mine since august of 2020 with just under 102k miles on it, so about 48k trouble free miles since then as far as the engine itself goes. I believe as long as I keep up with my oil changes and other maintenance like I have been, and choose quality fuel to put in it, I should be able to keep it going for a good while. I’m sure it also helps that I follow Eric’s advice and “floor it every once in a while” 😉😂 it’s nice to let that 385hp loose when the road is empty, and it helps that I have exhaust work done on mine. Lol
@@KHALABEEB thankfully, it’s not as often an issue on port injected cars, especially when maintained properly. On account of some of the sludge seen in this video, I’m willing to argue lower quality oil and/or improper frequency of oil changes contributed to this particular 4.6s demise. I’ve contributed about 48k miles or so to the cars current mileage, and haven’t had an issue out of the engine itself. Done an alternator and AC compressor, but the 4.6 itself hasn’t left me in a bind yet. I’m not looking forward to changing my spark plugs however, but I definitely need to do that here soon. I also do occasionally throw in a fuel system cleaner when I fill it up to help keep clean, and appropriate quantities of fuel coming through the injectors. So far, my nearly 3 years with this car give me strong belief that if nothing else, the engine will be plenty healthy if/when this car ever leaves me. Barring any circumstances beyond my control, at least.
I am surprised you didn't recognize this engine. I went to school on this engine and commented to the Korean instructor about how this thing looks just like a 4.6 liter Ford. He gave me a shit eating grin and said " No comment". I then asked him about the Borego looking like the Explorer, same grin, same answer.
I have a sneaking suspicion the reason why Hyundai didnt stick a V8 in their genesis coupe was to avoid a lawsuit from Ford. Also kinda funny that Hyundai released their 5.0 Tau the same year that Ford released the Coyote
Metal water pump Metal oil filter housing Metal thermostat housing and metal pipes for the water gallery in the center valley. Keyed harmonic balancer, Chain guide made to not fall apart after 50K miles. Metal oil pan. Sounds like BMW could learn a thing or two from Hyundai
I worked for Hyundai for a couple years. I left right as soon as the Theta engine fiasco started up. As much as the Theta is a turd, the Tau are pretty decent engines in my experience.
The Car Wizard has a video on those Theta direct injected engines... his customer had a 2015 Sonata... engine failure. Low oil, engine seized. Every place he called, including the dealerships, said they don't even touch those engines. No one rebuilds them. But, he said, you could replace the engine but it would cost more than the car's value. So this specific customer ended up getting rid of an otherwise perfect car with relatively low miles because it wasn't logical to fix it.
@@rushking19 The gamma is pretty bulletproof, too. 130,000 miles on my engine. Had to open the top to replace the turbo and it looks pristine in there.
Glad I checked UA-cam one last time before bed, to see this uploaded 7 seconds ago. The day just isn't right without a teardown. Hope you're all keeping well - it warms my heart to see just how much growth and success Eric has deservedly had. We're all here for the same reason and I love seeing how many of us have fuel running through our veins. Gives me hope for the future.
@@TheBandit7613 I wish. Getting ready to move out for summer and got driving lessons tomorrow as well... yet here I am at 3am. I'll still likely end up sleeping through my alarm anyway so what the hey.
Overall im pretty impressed with the engine design. Oil squiters, bed plate/girdle holding the crank with 4 bolts mains along with beefy chains keeping everything in harmony. This case was definitely caused by shitty gas and extended idling and maybe short tripping constantly.
I’ve got one of these recently but I work 2 miles from home and idle on break some times but I also floor it and do burnouts and stuff. Do you think I’ll have issues?
This episode reminds me of my Grandpa. He'd take me fishing in his late 60's GMC pickup. Every time we would start out he would floor it and shift through the gears. He'd look over at me with a big smile and say "Every now and again you gotta blow the carbon out!".
Thanks for doing this teardown...I have a 2010 Genesis with the 4.6...when you step on the gas, it goes...I take it on the turnpike every couple weeks just for fun!
Enjoy that fine piece of machinery. Genesis focuses on three key areas: Luxury, Performance, and Technology. I have a 2011 Genesis V8 Tau, I drive it like I stole it on the interstate!
I love that you did this Kia /Hyundai engine. That build up of extremely compressed carbon is exactly why I use premium and add Techron fuel system cleaner like twice between oil changes and never use regular.. Not to mention full synthetic 5w30 gets changed at least by 5000 miles. Of course I'm hoping for 300,000 miles. ✌️
I’m actually pretty excited about this one! I have a 2015 5.0 - always been curious at how they would tear down… knock on wood, haven’t heard much for major problems on them.
I'm impressed by the relative simplicity and stout build of that engine. No crazy timing system, just simple chains running the cams and long guides. Same chain running the oil pump and all of the chains are solid, beefy pieces. Those cylinder walls are beefy too. Big bearings and that chonky bed plate. This block looks like it will support some pretty serious power. The crank looks like a cast piece. The rods are decently hefty although not the most hi performance parts ever. I've never looked into Hyundai Tau motors, but I suspect that the rods and pistons are the weak point and the factory motor would probably be fine with 550+hp. You could probably push a lot more with all forged internals. Drop the compression slightly, big injectors and a turbo.
What a Father's Day gift. I've been looking for a Tau teardown for the longest and you gifted us with one. 😢 Can't wait for a 5.0 GDI, but the foundation I'm sure is here.
Ive always been fond of these korean v8s, really considering an equus as my next car, only bad thing is the lack of aftermarket support for a speed junkie but those cars are beautiful for a steal of a price
I had no idea that Hyundai made a V8. It did not seem overly complicated like so many of these modern engines do and the fact it's rated at 385 HP makes me wonder why it isn't more valuable or popular. I've learned a lot from your videos please keep up the good work!
Hyundai still has a rep for being a cheapskate's car, plus the Genesis sedan was pitched more as an E-class rival than a 5-series rival. Also they never put the V8 in the Genesis coupe even though I'm 75% sure it would've fit.
@@lust4life09 I wouldn't be surprised if someone tried to pitch it, but the brass said no. Reason I think it would've fit is because I've been under the hood of a couple Genesis coupes, as well as having a rough idea of the external dimensions of the Tau; might've been a case of it fitting, but not having enough room around the engine for crash dissipation.
@@CaptainSpadaro I hear that. I've seen under the hood of a Genesis coupe as well, and I agree, just not enough room in the engine bay for crash dissipation; unfortunately. :0
@@lust4life09 Well as of today people are putting GM LS V8 engines in the Genesis Coupe. So a V8 can defintely fit. Probably not a DOHC engine but a OHV engine due to its lower profile.
My stepmom had one of these, I was visiting and took her car out for something. At one point I needed to get on it and a giant black cloud came out the exhaust. Makes sense now.
Happy father's day to you and all of the other dads out there. Currently 5 hours from home visiting family with one of my little guys sleeping next to me, and a teardown is the perfect thing to end the night on 🤙
If you include 5L and below, the E39 M5, E92 M3, The 4.2L Audi V8, Lexus IS-F, all make about 400bhp and are N/A. Technically the E60 M5 V10 is only 5L and it makes 500bhp. Still, for Hyundai to make an engine that can hang out in a crowd of BMW M's, Audi's, etc is quite something
I believe the 4.2 in the S6 wagon and S8 hit 360hp. The normal ones ranged from 300 to 340hp depending on year and application. Only the RS4/RS5/R8 4.2 was over 400.
@@burntnougat5341Isn't it, and the engine configuration looks a lot simpler than the BMW setups. Therefore the $64,000 question is, why do the Germans do it? (Edit - spelling)
The 4.5L from the early Porsche Cayennes made 335hp, and the later 4.8L Cayenne GTS engines were 405hp. And then they stuck turbos on both for extra fun.
Thank you VERY much for taking the time to do this. I know that this takes a lot of your personal time,and I greatly appreciate this content. To my knowledge, this content in this much detail is not available anywhere else.
Super interesting teardown this week Eric, we never the Tau V8 in any Hyundai/Kia vehicles here in Australia (much to the disgust of car guys here). Looks to be a decent engine and definitely better than some of their other designs.
I’m curious, with how crazy (in a good way 😎🫡) Australians are, if these Tau V8s would’ve had better aftermarket support if they’d made it over there. 🤔 perhaps the Australian market would’ve pioneered performance modifications for them. Sadly it was just a bunch of old people that got into these when they first came out and it took forever for the v8 genesis sedans to get discovered/fall into ownership of the younger folks. I know of one guy here in the States though that’s been doing some fun stuff with his 5.0 R-spec sedan including running it on ethanol.
@@Genesis385 we have them in genesis I thought. But there's few genesis her but TONS of Hyundai and kias. Like they outnumber fords. We DON'T HAVE all the kia and Hyundai issues America has because the Korean made stuff we get is better quality than the US made kia and Hyundai.
Might as well do a combustion chamber cleaning using some Seafoam. Then change the oil, spark plugs, PVC valve. Throw in a new air filter and that engine should be purring like a kitten.
They're a beautiful car. Nice big machine with more bits and bobs than you can think of. But word of advice. Turn off the crash avoidance because if someone next to you is waiting to turn and you come up BESIDE them on a green light, it think you're about to rear end them even though they're in the NEXT lane. The thing will then automatically SLAM the brakes on and anyone behind you will rear end you. Badly designed collision avoidance on them.
I just got a 3.8 2009 non gdi sedan yesterday with 90k on it. Car is in mint condition. My 2013 Sedan is the 4.6 with 150k on it. Bulletproof cars! If you know how to maintain a vehicle they will last forever. These take little maintenance and drive very smoothly. Full synthetic oil changes and premium gas.
The Volvo/Yamaha B8444s would be a fun teardown. 4.4l naturally aspirated V8 with pfi and 315hp. I know they had some issues so there may be a few broken ones out there to play with. I think polestar developed a 650hp version of it in 2014 for use in their race cars.
I think that most of those race engines were for Australia's V8 supercars series when there was more competition, sadly now it just Chevy and Ford. I think one of their downfalls was a design flaw in the balance shaft bearings. After reading up about it the balance shaft is in the valley without adequate drainage for water and that in turn ruins the ball bearings on the balance shaft.
I am on my second one just because I love the car so much with this engine. My second Genesis has a lot more features than my first one. Including AWD with the 5.0. Wonderful combination once you put it in sport mode. Breaking traction is NOT a concern anymore.
I think he said that was a Genesis. They entered the market as a 50k luxury Sedan. People are easy on them. They were probably upset they got in an accident. Short trips will do the job, but that's just the nature of the territory. We techs do not mean to take advantage of hurt your vehicles when we perform service. Far better that the vehicle break in our possession. Basically part of a test drive, kind of like a Pro Delivery Inspection. Sometimes we let the consumer know that is what caused the malfunction or necessity of a repair. We recommend the same, at least when entering the highway, but some people just prefer caution. That said, that engine does appear to be very nicely engineered. I also appreciate the four bolt setup. Very nice work on Hyundai part. The bottom end is excellent. I also noticed very nice looking positions, I assume hypers. The connection rods also looked very nice, I couldn't tell if they were forged as they were surfaced in that area. But a strong looking designs. Lastly, Forged Crankshaft! Very nice.
1960-61, a neighbor's son bought a new Jaguar XK150 and said the dealer told him to 'open it up to blow out the carbon ever week or so'! So many cars never get on an expressway ramp, surprised that the hard carbon buildup doesn't break a lotta top rings on the rare occasion that they are revved!
Really enjoy all of your videos. Never had an appreciation for the complexity of internal combustion engines before seeing you disassemble them. Please keep searching for new engines to tackle.
As someone who rebuilds motors professionally, i get offered these for almost scrap value (and lots of other Hyundai and Kia engines) but i don't touch them and idk who does. In my experience, these engines aren't worth rebuilding because the reputation mostly. I know a lot of comments are praising this engines, but I've never seen one over 300k km, and i deal in a lot of engines. They seem very adequate in that they survive just a little after warranty ends for the owner to sell it. I've seen a lot of oil burners too, it seems to be piston rings. And inadequate filters. What i mean by reputation is that it's kind of obvious right now that Hyundai and Kia are the "cheap" brands, they're the car non car people buy as disposable appliances. Nobody wants to shell out the money for a 0 mileage Hyundai engine, there's a market for used ones as they do go bad often enough but they're not super expensive, because typically when the engine goes, the car goes. A direct comparison to the Toyota and Hondas, their run of the mill v6s GR and J series are still asking 2-4k around here and i've always got requests to rebuild them because even if unsellable here, pack them up and off to africa.
I agree. I think this might be one of the best four valve designs for the V8’s out there. It’s a shame. Somebody drove it like a grandma. By the way, that crank is a forged part, and those rods are pot metal crap. I was thinking this was kind of like the Ford modular v8 design, and then I saw the bed plate. Which in my opinion makes it superior. It just reinforces everything down low. Regardless - VERY cool engine. Thanks for the tear down.
My K900 5.0 has 215k miles. It's tuned on E85 and catless. I race it often. Never any issue outside of basic maintenance. Plus mine revs to 7,500 on every shift
Thank you. I would have never seen the inside of this engine if it weren't for you. Looks like the engineers did a great job with the cam chain guides and bottom end. I think something was wrong due to oil getting into the combustion chamber and causing carbon to build up on the quench area. Don't know why maybe EGR, crankcase ventilation or the wrong oil being used. Any way's the basic design of the engine looks good. Much better than the last engine you tore down.
I definitely agree, and that singular main bearing cap design would make for a very good candidate to up the power on one of these engines. 385hp from a 4.6 v8 is damn good from factory. I would just make sure to delete any emissions BS before modding it.
I have a 2011 Sonata. It has 233,000 miles on it. It burns oil at about a quart ever 500 miles. I'm going to see if it will make 300,000. 🤔 Other than the oil burning it's been a good car. The oil burning started at about 150,000 miles. Done my own oil changes at 7,000 miles. I've used Supertech Synthetic oil and High Mileage Supertech the entire time. Good oil for the price. I did bump oil viscosity to 5w-30 a long time ago. Anyway....thanks for the teardowns. They are fun to watch and informative. Here's to 200,000 subs. 👍😉
Thanks Eric for another great video. Totally agree with you that the performance numbers are super impressive and it's very evident that these are built to last. Unfortunately it seems like that trend is fading or is already gone. I look forward to your next Video.

In Germany, are the German cars like BMW, Mercedes Volkswagen, and others in the shop more than they’re on the road there like they are here in the US? I’ve always wondered that. They brag about making such great vehicles, but it seems like they’re just always broken all the time over here. I wonder if they make them better there than they do here
@@SteveB88 IMO people in the US don't seem to bother servicing their cars as most Europeans do. Most of the engines that are torn down on this channel are the result of negligence and misuse. Engines are identical and built on the same production line, but may have different performance levels for different markets. 🙂
Oh come on….who doesn’t love BMW’s hollow, oil-filled alternator bracket or my Audi’s thermostat living underneath the supercharger? Just fun, quirky Germanic engineering.
super interesting - I'd seen a few of those v8 Genesis sedans that smoke a bit and figured maybe it was the type of person that happens to buy them (ie fails to regularly change oil.) Looks like this might be a perfect example - not enough oil changes, maybe cheap gas and a bunch of short, low speed trips and still got 150k out of it. The motor actually seems really well designed - shame it got dumped for the turbo 6.
Pretty interesting, the engine and its Teardown. It seems an easy engine to work on, all things considered. At least you didn't complaint about multiple bolt sizes, like you sometimes do with other brands. Also, pretty smart tensioners in comparison with other engines.
I think the failure mode was that this engine smoked! If you look at the cylinder walls you can still see the factory hone job. After 150k miles that should be gone. I suspect that it was soft rings that then caused it to smoke... that also would explain the carbon buildup. Compression would be low and cause hard starting and poor performance. Cleaning the carbon out wouldn't have fixed anything... Great job on the tear down... (Remember the rocking pistons.... soft rings, no tension!)
I have a 2010 Kia Borrego which I bought for $ 8 k cad years ago. It now has 170 000 miles on, beautiful engine. Service every 3000 miles. Been all over Canada in it and really is a pleasure to drive
I used to work for Kia for a couple years a handful of years ago and I don't think I ever saw one of these engines in person (except at a training center). I only saw one or two Borrego's and both were V6's.
This engine was roughly based on the Mitsubishi 8A8 that was co built by Hyundai. If you compare the block design they are very similar. With a shorter stroke and a larger bore they were able to squeeze out some decent numbers and increase the displacement. The firing order is also very uncommon, in the last 20 years I think only the 8A8 and Tau use it. It has an interesting sound with a proper exhaust system.
@@OffGridInvestor interesting! I'll keep my eyes out on the forums to look for a hybrid 8A8/Tau. I've had a 2011 Genesis 4.6 for the past 5 years without issue. If you're interested a bit about these cars they also have a ZF 6HP26(7 series, 5 series, Bentley Continental, Rolls Royce Phantom, and many other luxury cars). It was also the first car that Lexicon worked with outside of Rolls Royce. If you cross reference parts in the infotainment system you'll find that some of the modules are the same. They also respond fairly well to light modification. With a tune, secondary cat deletes and a cold air intake some see 340 ish rwhp which is roughly 400hp at the crank.
I own a 2009 Kia Borrego with a 4.6l V8 I put 307000 km on it and it run very well and i use it to tow my 6000 pounds RV. By far the best SUV I ever owned..
We had a Genesis with the 4.6 show up at my shop a year or two ago with a timing issue (can't recall exactly what it was). Lead tech looked at Identifix to get an idea of where to go with the diag and the lone submitted fix for this issue, whatever it was, was to...replace the long block. Okaaaaaaaaaaaaaaaaaaaaaaay. Car left on a flatbed IIRC.
You can get a lot of carbon buildup when the O2 sensor is dying, if it's one of ones that uses the old-style sensor whose voltage goes to zero as the mixture goes lean. With that type, an intermittent signal or anything that causes the voltage to read low will result in the ECM running the fuel delivery up. Combine that with an engine whose service intervals might have been a bit long, and you're set for buildup of crud in the chambers.
Interesting, though wouldn't the car throw a code if the O2s were dying? It also wouldn't pass smog. I was hoping Eric would have given a better explanation as to why that specific engine had so much carbon IN the cylinders...
@@carsonw722 It may have been intermittently tossing an O2 code, but a heck of a lot of people have become used to the way that trouble codes can be a bit Chicken Little-like at times, and often will ignore the O2 in particular until they don't have a choice. Also, if the car is registered in an area with lax emissions testing requirements, like most of rural Texas, it will pass as long as the Check Engine indicator isn't lit when it gets in front of the tech. No history and no driver feedback came with the core, so any of that could have been happening, and we just don't know.
My guess is the oil control rings got stuck, they look almost flush when you showed the pistons then, it started burning oil and that was the carbon on the pistons.
Thinking the same thing. When those oil control rings get stuck, it's still a perfectly fine engine, just burns a lot of oil and builds up carbon on the pistons fairly quick. It's a double-edged sword though too because if you floor it to try to "clean" away the carbon deposits, it only accelerates carbon buildup as it allows more oil to enter the combustion chamber which adds to the carbon buildup and can possibly lead to a burnt exhaust valve (happened to me), clogged cats, and/or O2 sensors failing or reading erratically
He specifically said the rings were free. He's also really shade tree and inaccurate keeping going back to the carbon which was NOT the cause of failure. Bad storage killed this engine. It was running when the car was rear ended. While we can't know if a check engine light was on, etc, every single car and truck prior to things really getting tuned in around the turn of the century, ran the latter half of its life with more carbon than that.
Much like the pre-GDI Lambda V6, this is an absolutely tough engine bolted into depreciation queens that owners never cares about. I honestly can't fault Hyundai for their current ways, as their owners didn't care enough to maintain their old Mitsubishi engines, continued not caring when they actually made some really rugged engines and attempted to rival Toyota on some reliability fronts, and now have just given up, making cars laser-focused on their "60k and throw away" cheapskate customer base. Their roughly 2006-2011ish engines are well engineered and built engines that can withstand near-zero service and not break as well as a 2GR or MZ. The cars just never last long enough to matter.
You gotta let loose from time to time. Nothing stupid, just clear the engine every now and then, like we clear our throats. Odd analogy yeah but you get the point. Definitely signs of poor fuel ran through this.
The Tau could run on regular gas. Hyundai's computer would monitor the engine and de-rate the performance. Hyundai even published separate power & economy numbers. I believe the same is true for their 5 liter V8 & their naturally aspirated 3.8 liter; IIRC, the 5 liter went from 429 hp to 375-ish if regular was used instead of premium. Really enjoy the channel and the editing. Something might take three minutes, but you speed it up to prevent subjecting viewers to three minutes of bolt removals. Thank you.
That is a nice straightforward engine design. The older KIA / Hyundai pre GDI engines were good. The newer GDI stuff perhaps not so much. My wife drove a 2007 KIA with the 2.7L V6, it ran like new at 150K miles, used no oil, transmission worked like new also. Alas, my kid totaled it and that was all she wrote. Who knows how long it would have kept going.
The 2.7l is a great engine mine in my tiburon has 200k miles and I drive it hard abd rev it past what the factory intended and its still running strong .
If I may make an observation, having grown up working on the 'old' technology motors. Watching your videos it appears that these new hi tech motors actually run dirtier. The only time I would see that much carbon inside a motor was 200,000 + miles without an oil change and carburetor tuning completely for majority of those miles. Thanks for the videos
Nah. If you were around for the late 90's working on vehicles from 86-91 manufacture date- I'm talking early and mid generation 4.3 GM, Ford 3.8, GM 305/350 TBI, Chrysler/Mits 2.6 - they were all much worse than this by the 50-60% point in their lifespan. At that point I was doing tear downs- in fact much as Eric does, the difference being we were trying to do budget rebuilds for fleets and car lots. Quite successful in terms of quality, but it was a crazy low margin business. I left, but I think cash for clunkers did them in as a business model and that aspect of the industry had just been too weakened by trying to fix customer engines so *they* could profit- at our expense- to ever bounce back.
@@iadr I have to admit that when I got those vehicles they went straight to the junkyard, all the vacuum operated devices and the control valves made them not worth working on, lol
Yes and no. DI and silly long oil service intervals have made "modern tech" look bad and added sources of carbon and dirt, but the core "old style" processes themselves are much cleaner and more efficient in modern engines. The whole point of PCV, EGR, DPF is to recirculate crap that used to be vented out the exhaust, back into the intake Tldr emissions tech bad, combustion efficiency tech good.
yeh, all the carbon being retained in stuff like oil and recirc systems and all of that was just being yeeted into the upper atmosphere. newer engines are burning purer fuels with detergents baked in, and doing a _much_ better job of it, they just look worse bc they do a better job at doing it _efficiently,_ and they hold on to pollutants instead of just shitting them into the sky. and like Eric said, it's a 4.6 liter putting out as much _wheel horsepower_ in a genesis as a 6.5 liter olds super rocket could put out _at the crank with no accessories._ while getting what, 2x the gas mileage? 2.5x? hard to complain about any of that when you can abuse the hell out of them on top of everything else 🤷
These are great engines, the V6 is very good too, i have 2 Borrego V6 with high milleage, and they're still running great and don't burn a drop of oil, the Borrego is a very reliable SUV, and you can have them for cheap.
I own a genesis sedan with one of these 4.6 engines in it. I typically stick to the old reliable 3k mile oil change, synthetic 5w-30 with a wix filter. Comes out to about $75 or so depending on price fluctuations for the oil and filter, but I’d rather spend that $75 every few months than to need an engine or new car. 😅
You look at the engines that they actually sell and they’re crap. Then this, they sell barely any and its so well made, so beautifully designed, so simple.
I owned a 2009 Kia Borrego quite frankly it was the best vehicle I’ve ever owned. It never broke never nothing and I had 140,000 on it when I sold it and he just in a tuneup and spark plugs and it ran like a champ never had an issue.
I bought 2 kia spectras new, a 2005 and 2007. Both were great cars. I bought a new 2017 Hyundai Elantra , fully loaded, it just turned 100.000 miles last week. Absolutely 0 repairs, and 0 issues. In May of 2021, I bought a new kia K5 GT LINE with premium package. Very nice car, 26.000 miles now, again, no issues . The Elantra is now mostly used for my 78 mile round trip to work. I bought the K5 at just the right time, paid MSRP, and qualified for thier 0.0 intrest promotion! SWEET!
I had a 2011 genesis with one of these motors briefly at the end of 2022. I say briefly because a knock developed in the engine shortly after and when I dropped the oil to see what was up, I had a ton of glitter in the oil filter and in the oil itself. Seriously looked like an oil painting with how it was mixed in. Didint keep the car after that and from what I understand. You gotta use 5w-30 in these, the manual even said you could. 5w-20 is what the oil cap says but that is way to thin for these engines
I have the Hyundai 5.0 engine and watching this video was a joy. I hope one day you can obtain a 5.0 GDI from Hyundai or Kia and possibly compare both 4.6 and 5.0 if you still have this engine nearby. I think it will make for an interesting video and to hear your thoughts on the two propulsion system.
not only a good flooring it to clean out putting some good quality injector cleaner in gas tank a couple times.. On my gas cars which tend to be hyundai when the tank gets to 1/4 tank left i put a whole bottle of techron in and drive it like i stole it for a couple days.. hard acceleration and some WOT runs.. you can start to feel it getting cleaner,, then when i fill up i put another bottle in tanks and run it normal.. techron and seafoam are two of the best for cleaning out injectors and carbon deposits in gas engines. PS don't know how you film and post so fricken fast. it's a job on both ends... THANKS a million.
The thing about Hyundai is they tend to over exaggerate their engine power outputs. And it gets worse when you compare to the Germans who do the opposite.
I have a 2012 Hyundai Azera Limited that I bought in 2016 with 33K miles on it. It's just shy of 100K as of now 5/13/24. That vehicle seems to have it own kind of engine that's not in other Hyundai's, Genisis or Kia models or so I've read from many articles and forums online.. It's a V6 GDI 3.3 liter I'm very curious whether you've ever gotten your hands on one if those. I'm also on top of its maintenance needs and do full synthetic oil every 6K miles. It's still going strong, smooth and quiet!!!!! Other than a new engine mount last fall (I live in southern AZ) I've had zero issues. It still runs and looks like new. It's a pleasure to drive. Great road trip car. 35 MPG highway.
My borrego has this engine and is now cocking at 250 miles with no problem. Just replace pcv valve last week and found that i took out the original one.

@@alro2434 I understand american for this: you got a lot of immigration from us back then, and mainly from the south Italy and lower classes. Now you've to know that Italy is *heavily* different between north and south even now, Milan compares to NYC like Enna (Sicily) compares to some rural Alabama town. And back then was even worse: around 1900 four millions of Italians (mainly from the poor south, where Mafia has its home) came to the US. Back then the illiteracy was around 35% in the north of IT and up to 92% in the south. You got those 92%...

For the first time ever my 22 month old son is actually leaning against my shoulder to watch instead of running away when he sees a "Dad" video
Lol my boy watched some Hoonigan This vs That with me and now goes around doing arm drops saying "go"
TMI
My son said I watch 'dad' videos
Now, that is an absolutely great Father's Day gift.
Pro tip give your son some linclon logs. Turn off the phone
I am actually impressed at the simplicity and robustness of the design. Large bearings, simple timing chain setups (that seem to hold up well for 150k), and no crazy fasteners!!
the heads off chain service kinda sucks tho
@@misterdeedeedee Yep..but they looked pretty good for 150k miles.
@daktah if you have a recent Hyundai, you quickly learn that 150k is a target the motor probably won't see.
@@daw162exactly. I swear those motors are designed to fail at 150k.
I do like the simplicity of Hyundai/kia engines. There tends to be more space in the engine bay for working. Seems fairly rare on new vehicles these days.
As the current owner of a 2011 4.6 genesis sedan, I had no choice but to join in for this video. Just turned over 150k miles yesterday and still going strong.
Holy crap, I immediately went to write this comment as soon as I opened the video and am returning shortly after to laugh at how this engine is from a 2011 genesis with 150k on it 😂💀
Dude, get a carbon clean treatment asap!🤣👍
Right? Read this comment after hearing it in the video and couldn't help but raise an eyebrow. Hopefully yours gives you many more miles of trouble free motoring. From what I've seen in this video alone (admittedly not a wealth of experience) they seem to be good engines.
@@_supasped_ I’ve had mine since august of 2020 with just under 102k miles on it, so about 48k trouble free miles since then as far as the engine itself goes. I believe as long as I keep up with my oil changes and other maintenance like I have been, and choose quality fuel to put in it, I should be able to keep it going for a good while. I’m sure it also helps that I follow Eric’s advice and “floor it every once in a while” 😉😂 it’s nice to let that 385hp loose when the road is empty, and it helps that I have exhaust work done on mine. Lol
@@KHALABEEB thankfully, it’s not as often an issue on port injected cars, especially when maintained properly. On account of some of the sludge seen in this video, I’m willing to argue lower quality oil and/or improper frequency of oil changes contributed to this particular 4.6s demise. I’ve contributed about 48k miles or so to the cars current mileage, and haven’t had an issue out of the engine itself. Done an alternator and AC compressor, but the 4.6 itself hasn’t left me in a bind yet. I’m not looking forward to changing my spark plugs however, but I definitely need to do that here soon. I also do occasionally throw in a fuel system cleaner when I fill it up to help keep clean, and appropriate quantities of fuel coming through the injectors. So far, my nearly 3 years with this car give me strong belief that if nothing else, the engine will be plenty healthy if/when this car ever leaves me. Barring any circumstances beyond my control, at least.
Drive it like you stole it for about a week maybe youll clear up that carbon lol
I am surprised you didn't recognize this engine. I went to school on this engine and commented to the Korean instructor about how this thing looks just like a 4.6 liter Ford. He gave me a shit eating grin and said " No comment". I then asked him about the Borego looking like the Explorer, same grin, same answer.
it's an adaptation of a Mitsubishi 8a8 and ford 4.6
I have a sneaking suspicion the reason why Hyundai didnt stick a V8 in their genesis coupe was to avoid a lawsuit from Ford.
Also kinda funny that Hyundai released their 5.0 Tau the same year that Ford released the Coyote
@@LSDelta92just direct competition there imo
Metal water pump
Metal oil filter housing
Metal thermostat housing and metal pipes for the water gallery in the center valley.

Sounds like BMW could learn a thing or two from Hyundai
Wow an intelligently designed engine for maintenance. I must say I’m impressed.
It's a Hyundai thing.
It was not at all an intelligent design it's a stupid design
I worked for Hyundai for a couple years. I left right as soon as the Theta engine fiasco started up. As much as the Theta is a turd, the Tau are pretty decent engines in my experience.
The Car Wizard has a video on those Theta direct injected engines... his customer had a 2015 Sonata... engine failure. Low oil, engine seized. Every place he called, including the dealerships, said they don't even touch those engines. No one rebuilds them. But, he said, you could replace the engine but it would cost more than the car's value. So this specific customer ended up getting rid of an otherwise perfect car with relatively low miles because it wasn't logical to fix it.
The tau, delta, sigma, and beta are great engines
@@rushking19 lambda II fucking slays
@@rushking19 The gamma is pretty bulletproof, too. 130,000 miles on my engine. Had to open the top to replace the turbo and it looks pristine in there.
Hyundai & decent don't go together.
Glad I checked UA-cam one last time before bed, to see this uploaded 7 seconds ago. The day just isn't right without a teardown. Hope you're all keeping well - it warms my heart to see just how much growth and success Eric has deservedly had. We're all here for the same reason and I love seeing how many of us have fuel running through our veins. Gives me hope for the future.
I'm getting ready to make dinner and your going to bed?
Tomorrow is Sunday, you can sleep in.
@@TheBandit7613 I wish. Getting ready to move out for summer and got driving lessons tomorrow as well... yet here I am at 3am. I'll still likely end up sleeping through my alarm anyway so what the hey.
Overall im pretty impressed with the engine design. Oil squiters, bed plate/girdle holding the crank with 4 bolts mains along with beefy chains keeping everything in harmony. This case was definitely caused by shitty gas and extended idling and maybe short tripping constantly.
I’ve got one of these recently but I work 2 miles from home and idle on break some times but I also floor it and do burnouts and stuff. Do you think I’ll have issues?
@@hitbythese keep idling down its never good to idle for extended periods. No more then 10 minutes.
Vehicles are ment to be driven. Otherwise they brake
This episode reminds me of my Grandpa. He'd take me fishing in his late 60's GMC pickup. Every time we would start out he would floor it and shift through the gears. He'd look over at me with a big smile and say "Every now and again you gotta blow the carbon out!".
As the owner of a 2009 Genesis 4.6L with 176k miles, this was interesting to watch. Thanks for the vid!
Thanks for doing this teardown...I have a 2010 Genesis with the 4.6...when you step on the gas, it goes...I take it on the turnpike every couple weeks just for fun!
Enjoy that fine piece of machinery. Genesis focuses on three key areas: Luxury, Performance, and Technology. I have a 2011 Genesis V8 Tau, I drive it like I stole it on the interstate!
Absolutely love these engine teardowns! Thanks for your hard work Eric!
I love that you did this Kia /Hyundai engine. That build up of extremely compressed carbon is exactly why I use premium and add Techron fuel system cleaner like twice between oil changes and never use regular.. Not to mention full synthetic 5w30 gets changed at least by 5000 miles. Of course I'm hoping for 300,000 miles. ✌️
It says you can use regular gas
@ryanaddy1135 How many miles do yoiu have now?
@@mackfar27 109k
I’m actually pretty excited about this one!
I have a 2015 5.0 - always been curious at how they would tear down… knock on wood, haven’t heard much for major problems on them.
I'm impressed by the relative simplicity and stout build of that engine. No crazy timing system, just simple chains running the cams and long guides. Same chain running the oil pump and all of the chains are solid, beefy pieces. Those cylinder walls are beefy too. Big bearings and that chonky bed plate. This block looks like it will support some pretty serious power. The crank looks like a cast piece. The rods are decently hefty although not the most hi performance parts ever.
I've never looked into Hyundai Tau motors, but I suspect that the rods and pistons are the weak point and the factory motor would probably be fine with 550+hp. You could probably push a lot more with all forged internals. Drop the compression slightly, big injectors and a turbo.
the 5.0 tau is a borred out version of this motor and is good for 430 stock but on e85 with no other upgrades it’s pushing 520*
What a Father's Day gift. I've been looking for a Tau teardown for the longest and you gifted us with one. 😢 Can't wait for a 5.0 GDI, but the foundation I'm sure is here.
Ive always been fond of these korean v8s, really considering an equus as my next car, only bad thing is the lack of aftermarket support for a speed junkie but those cars are beautiful for a steal of a price
I had no idea that Hyundai made a V8. It did not seem overly complicated like so many of these modern engines do and the fact it's rated at 385 HP makes me wonder why it isn't more valuable or popular. I've learned a lot from your videos please keep up the good work!
Hyundai still has a rep for being a cheapskate's car, plus the Genesis sedan was pitched more as an E-class rival than a 5-series rival.
Also they never put the V8 in the Genesis coupe even though I'm 75% sure it would've fit.
@@CaptainSpadaro V8 in the Genesis Coupe?! Take my money, that would be a panty-dropper!
@@lust4life09 I wouldn't be surprised if someone tried to pitch it, but the brass said no.
Reason I think it would've fit is because I've been under the hood of a couple Genesis coupes, as well as having a rough idea of the external dimensions of the Tau; might've been a case of it fitting, but not having enough room around the engine for crash dissipation.
@@CaptainSpadaro I hear that. I've seen under the hood of a Genesis coupe as well, and I agree, just not enough room in the engine bay for crash dissipation; unfortunately. :0
@@lust4life09 Well as of today people are putting GM LS V8 engines in the Genesis Coupe. So a V8 can defintely fit. Probably not a DOHC engine but a OHV engine due to its lower profile.
My stepmom had one of these, I was visiting and took her car out for something. At one point I needed to get on it and a giant black cloud came out the exhaust. Makes sense now.
I had a 2010 Genesis 4.6 and it did not require premium gas. However, it did come from the factory with a defective drive shaft carrier bearing.
Happy father's day to you and all of the other dads out there. Currently 5 hours from home visiting family with one of my little guys sleeping next to me, and a teardown is the perfect thing to end the night on 🤙
This is the first DOHC V8 design I actually admire.
If you include 5L and below, the E39 M5, E92 M3, The 4.2L Audi V8, Lexus IS-F, all make about 400bhp and are N/A. Technically the E60 M5 V10 is only 5L and it makes 500bhp. Still, for Hyundai to make an engine that can hang out in a crowd of BMW M's, Audi's, etc is quite something
I believe the 4.2 in the S6 wagon and S8 hit 360hp. The normal ones ranged from 300 to 340hp depending on year and application. Only the RS4/RS5/R8 4.2 was over 400.
4.0 v8 in the e92 m3 makes 414hp
It's really impressive this engine can hang with the BMW S engines
@@burntnougat5341Isn't it, and the engine configuration looks a lot simpler than the BMW setups. Therefore the $64,000 question is, why do the Germans do it?
(Edit - spelling)
The 4.5L from the early Porsche Cayennes made 335hp, and the later 4.8L Cayenne GTS engines were 405hp. And then they stuck turbos on both for extra fun.
Thank you VERY much for taking the time to do this. I know that this takes a lot of your personal time,and I greatly appreciate this content. To my knowledge, this content in this much detail is not available anywhere else.
Super interesting teardown this week Eric, we never the Tau V8 in any Hyundai/Kia vehicles here in Australia (much to the disgust of car guys here). Looks to be a decent engine and definitely better than some of their other designs.
I’m curious, with how crazy (in a good way 😎🫡) Australians are, if these Tau V8s would’ve had better aftermarket support if they’d made it over there. 🤔 perhaps the Australian market would’ve pioneered performance modifications for them. Sadly it was just a bunch of old people that got into these when they first came out and it took forever for the v8 genesis sedans to get discovered/fall into ownership of the younger folks. I know of one guy here in the States though that’s been doing some fun stuff with his 5.0 R-spec sedan including running it on ethanol.
YES WE DID. In the genesis I believe. There's not tons of genesis but they're around
@@Genesis385 we have them in genesis I thought. But there's few genesis her but TONS of Hyundai and kias. Like they outnumber fords. We DON'T HAVE all the kia and Hyundai issues America has because the Korean made stuff we get is better quality than the US made kia and Hyundai.
@@OffGridInvestor interesting. I’m from the US so I couldn’t tell you.
My first thought was the expense of our petrol but that's not stopped the sale of these SUVs and American sized utes.
I had one of these. Got 130K miles and traded her in. Absolutely zero issues mechanically. Electronics were a different story.
Impressive engine. I may look for a Genesis with that engine when I shop for my next used car.
Might as well do a combustion chamber cleaning using some Seafoam. Then change the oil, spark plugs, PVC valve. Throw in a new air filter and that engine should be purring like a kitten.
They're a beautiful car. Nice big machine with more bits and bobs than you can think of. But word of advice. Turn off the crash avoidance because if someone next to you is waiting to turn and you come up BESIDE them on a green light, it think you're about to rear end them even though they're in the NEXT lane. The thing will then automatically SLAM the brakes on and anyone behind you will rear end you. Badly designed collision avoidance on them.
My genesis had 230k miles still running :)
Interesting stuff every week! Hint on removing parts (old method) "Continue removing bolts 'till the part you want falls off"
I just got a 3.8 2009 non gdi sedan yesterday with 90k on it. Car is in mint condition. My 2013 Sedan is the 4.6 with 150k on it. Bulletproof cars! If you know how to maintain a vehicle they will last forever. These take little maintenance and drive very smoothly. Full synthetic oil changes and premium gas.
The Volvo/Yamaha B8444s would be a fun teardown. 4.4l naturally aspirated V8 with pfi and 315hp. I know they had some issues so there may be a few broken ones out there to play with. I think polestar developed a 650hp version of it in 2014 for use in their race cars.
The Noble m600 uses one. 660 HP
add to that the ford SHO v8 and see just how similar or different they really are. Yamaha claims they're not at all similar buuut
I think that most of those race engines were for Australia's V8 supercars series when there was more competition, sadly now it just Chevy and Ford.
I think one of their downfalls was a design flaw in the balance shaft bearings. After reading up about it the balance shaft is in the valley without adequate drainage for water and that in turn ruins the ball bearings on the balance shaft.
Autonation has one S80 V8. I was tempted. 😂😂😂
The 4.6L and 5.0L Tau, from what I’ve heard, are pretty good engines
I prefer their Lambda V6's but yes the TAU V8's were definitely decent engines!
I am on my second one just because I love the car so much with this engine. My second Genesis has a lot more features than my first one. Including AWD with the 5.0. Wonderful combination once you put it in sport mode. Breaking traction is NOT a concern anymore.
I agree. The design was actually pretty impressive. I wouldn't hesitate to use one in a custom build.
Good one ,Eric 👍
chev should take a look..but then thy,d fk the design,,as usual..
I think he said that was a Genesis. They entered the market as a 50k luxury Sedan. People are easy on them. They were probably upset they got in an accident. Short trips will do the job, but that's just the nature of the territory. We techs do not mean to take advantage of hurt your vehicles when we perform service. Far better that the vehicle break in our possession. Basically part of a test drive, kind of like a Pro Delivery Inspection. Sometimes we let the consumer know that is what caused the malfunction or necessity of a repair. We recommend the same, at least when entering the highway, but some people just prefer caution. That said, that engine does appear to be very nicely engineered. I also appreciate the four bolt setup. Very nice work on Hyundai part. The bottom end is excellent. I also noticed very nice looking positions, I assume hypers. The connection rods also looked very nice, I couldn't tell if they were forged as they were surfaced in that area. But a strong looking designs. Lastly, Forged Crankshaft! Very nice.
Enjoy your tear downs, personality and humor. Keep the vids coming! Thanks for bringing us along.
I don’t think he wants to date you. 🤨

Really enjoy all of your videos. Never had an appreciation for the complexity of internal combustion engines before seeing you disassemble them. Please keep searching for new engines to tackle.
I thought I was pretty clever and handy after I changed a Subaru head gasket…..then I opened a mechanical watch.
As someone who rebuilds motors professionally, i get offered these for almost scrap value (and lots of other Hyundai and Kia engines) but i don't touch them and idk who does. In my experience, these engines aren't worth rebuilding because the reputation mostly. I know a lot of comments are praising this engines, but I've never seen one over 300k km, and i deal in a lot of engines. They seem very adequate in that they survive just a little after warranty ends for the owner to sell it. I've seen a lot of oil burners too, it seems to be piston rings. And inadequate filters.
What i mean by reputation is that it's kind of obvious right now that Hyundai and Kia are the "cheap" brands, they're the car non car people buy as disposable appliances. Nobody wants to shell out the money for a 0 mileage Hyundai engine, there's a market for used ones as they do go bad often enough but they're not super expensive, because typically when the engine goes, the car goes. A direct comparison to the Toyota and Hondas, their run of the mill v6s GR and J series are still asking 2-4k around here and i've always got requests to rebuild them because even if unsellable here, pack them up and off to africa.
I agree. I think this might be one of the best four valve designs for the V8’s out there. It’s a shame. Somebody drove it like a grandma. By the way, that crank is a forged part, and those rods are pot metal crap. I was thinking this was kind of like the Ford modular v8 design, and then I saw the bed plate. Which in my opinion makes it superior. It just reinforces everything down low. Regardless - VERY cool engine. Thanks for the tear down.
Just bought a 2013 Equus with he 5.0. 69k miles. Damn engine is stout. So far so good. Got me looking for another or a K900 with the same motor.
My K900 5.0 has 215k miles. It's tuned on E85 and catless. I race it often. Never any issue outside of basic maintenance. Plus mine revs to 7,500 on every shift
Thank you.
I would have never seen the inside of this engine if it weren't for you.
Looks like the engineers did a great job with the cam chain guides and bottom end.
I think something was wrong due to oil getting into the combustion chamber and causing carbon to build up on the quench area. Don't know why maybe EGR, crankcase ventilation or the wrong oil being used.
Any way's the basic design of the engine looks good.
Much better than the last engine you tore down.
I definitely agree, and that singular main bearing cap design would make for a very good candidate to up the power on one of these engines. 385hp from a 4.6 v8 is damn good from factory. I would just make sure to delete any emissions BS before modding it.
I have a 2011 Sonata.
It has 233,000 miles on it.
It burns oil at about a quart ever 500 miles.
I'm going to see if it will make 300,000. 🤔
Other than the oil burning it's been a good car.
The oil burning started at about 150,000 miles.
Done my own oil changes at 7,000 miles.
I've used Supertech Synthetic oil and High Mileage Supertech the entire time. Good oil for the price.
I did bump oil viscosity to 5w-30 a long time ago.
Anyway....thanks for the teardowns. They are fun to watch and informative.
Here's to 200,000 subs. 👍😉
Thanks Eric for another great video. Totally agree with you that the performance numbers are super impressive and it's very evident that these are built to last. Unfortunately it seems like that trend is fading or is already gone. I look forward to your next Video.

Oh come on….who doesn’t love BMW’s hollow, oil-filled alternator bracket or my Audi’s thermostat living underneath the supercharger? Just fun, quirky Germanic engineering.
The S65 was a 4L V8 with port injection and made 400 hp and revved to 8300 RPM. The MPi TAU engine is still pretty dope.
super interesting - I'd seen a few of those v8 Genesis sedans that smoke a bit and figured maybe it was the type of person that happens to buy them (ie fails to regularly change oil.) Looks like this might be a perfect example - not enough oil changes, maybe cheap gas and a bunch of short, low speed trips and still got 150k out of it. The motor actually seems really well designed - shame it got dumped for the turbo 6.
Some of the 5.0 engines in the 2012-2014 had issues with piston rings and excessive blow-by
Turbo 6 was lighter and the car became more powerful than the V8. Which is odd but that's what happened
I haven't lost to a V6 yet. I'm Catless E85 in my 5.0 Kia
Waited til Father’s Day morning for my teardown treat. Happy Father’s Day to Eric and all the dads out there!
Pretty interesting, the engine and its Teardown.
It seems an easy engine to work on, all things considered. At least you didn't complaint about multiple bolt sizes, like you sometimes do with other brands.
Also, pretty smart tensioners in comparison with other engines.
I have this engine in my Equus. Quiet and smooth, especially mated to the ZF 6 speed
I bet that ZF transmission is better than Hyundai's own 8 speed transmission. lol
@@mackfar27did not experience other Hyundai 8 speeds, but yes the ZF is smooth if you maintain it well
@@kalani1987 I had the 2015 Genesis 5.0 and now a 2018 Genesis G80 5.0 HTRAC and the in-house transmission is A LOT better than 2015.
I think the failure mode was that this engine smoked! If you look at the cylinder walls you can still see the factory hone job. After 150k miles that should be gone. I suspect that it was soft rings that then caused it to smoke... that also would explain the carbon buildup. Compression would be low and cause hard starting and poor performance. Cleaning the carbon out wouldn't have fixed anything... Great job on the tear down... (Remember the rocking pistons.... soft rings, no tension!)
Some soccer mom driving slow and waiting outside of school for the kids for 20 minutes idling because she wanted the AC or heat.
I have a 2010 Kia Borrego which I bought for $ 8 k cad years ago. It now has 170 000 miles on, beautiful engine. Service every 3000 miles. Been all over Canada in it and really is a pleasure to drive
That is a stout engine for sure, forged crank, PM fracture cap rods, four bolt mains/bed plate, extra thick main webs.
Great video Eric!! Sad to see a wasted engine because of a wreck!!
I used to work for Kia for a couple years a handful of years ago and I don't think I ever saw one of these engines in person (except at a training center). I only saw one or two Borrego's and both were V6's.
Love the variety of manufacturers for these teardowns. Still surprised this one made that much hp!
I love these teardowns, thanks!
I've got a Civic with 549k. Thanks for the video Eric nicely done. Take care of yourself and family and be Blessed ❤️❤️👍.
This engine was roughly based on the Mitsubishi 8A8 that was co built by Hyundai. If you compare the block design they are very similar. With a shorter stroke and a larger bore they were able to squeeze out some decent numbers and increase the displacement.
The firing order is also very uncommon, in the last 20 years I think only the 8A8 and Tau use it. It has an interesting sound with a proper exhaust system.
There's a few that Mitsubishi and Hyundai done together. I have seen a video where they had a Mitsubishi block with all Hyundai parts and it WAS FINE
@@OffGridInvestor interesting! I'll keep my eyes out on the forums to look for a hybrid 8A8/Tau. I've had a 2011 Genesis 4.6 for the past 5 years without issue. If you're interested a bit about these cars they also have a ZF 6HP26(7 series, 5 series, Bentley Continental, Rolls Royce Phantom, and many other luxury cars). It was also the first car that Lexicon worked with outside of Rolls Royce. If you cross reference parts in the infotainment system you'll find that some of the modules are the same. They also respond fairly well to light modification. With a tune, secondary cat deletes and a cold air intake some see 340 ish rwhp which is roughly 400hp at the crank.
I own a 2009 Kia Borrego with a 4.6l V8 I put 307000 km on it and it run very well and i use it to tow my 6000 pounds RV. By far the best SUV I ever owned..
We had a Genesis with the 4.6 show up at my shop a year or two ago with a timing issue (can't recall exactly what it was). Lead tech looked at Identifix to get an idea of where to go with the diag and the lone submitted fix for this issue, whatever it was, was to...replace the long block.
Okaaaaaaaaaaaaaaaaaaaaaaay.
Car left on a flatbed IIRC.
Straight to a scrap yard.
@@christinesommerfeld9815 probably :/
I gain a lot of knowledge every time I watch one of your autopsies. Please keep it up, you are entertaining and informative!
You can get a lot of carbon buildup when the O2 sensor is dying, if it's one of ones that uses the old-style sensor whose voltage goes to zero as the mixture goes lean. With that type, an intermittent signal or anything that causes the voltage to read low will result in the ECM running the fuel delivery up. Combine that with an engine whose service intervals might have been a bit long, and you're set for buildup of crud in the chambers.
Interesting, though wouldn't the car throw a code if the O2s were dying? It also wouldn't pass smog. I was hoping Eric would have given a better explanation as to why that specific engine had so much carbon IN the cylinders...
@@carsonw722 It may have been intermittently tossing an O2 code, but a heck of a lot of people have become used to the way that trouble codes can be a bit Chicken Little-like at times, and often will ignore the O2 in particular until they don't have a choice. Also, if the car is registered in an area with lax emissions testing requirements, like most of rural Texas, it will pass as long as the Check Engine indicator isn't lit when it gets in front of the tech. No history and no driver feedback came with the core, so any of that could have been happening, and we just don't know.
@@carsonw722 for many states there just isn't any vehicle inspections
I appreciate that you provide insight into such a variety of ICE, keep on grinding
My guess is the oil control rings got stuck, they look almost flush when you showed the pistons then, it started burning oil and that was the carbon on the pistons.
Thinking the same thing. When those oil control rings get stuck, it's still a perfectly fine engine, just burns a lot of oil and builds up carbon on the pistons fairly quick. It's a double-edged sword though too because if you floor it to try to "clean" away the carbon deposits, it only accelerates carbon buildup as it allows more oil to enter the combustion chamber which adds to the carbon buildup and can possibly lead to a burnt exhaust valve (happened to me), clogged cats, and/or O2 sensors failing or reading erratically
He specifically said the rings were free. He's also really shade tree and inaccurate keeping going back to the carbon which was NOT the cause of failure. Bad storage killed this engine. It was running when the car was rear ended. While we can't know if a check engine light was on, etc, every single car and truck prior to things really getting tuned in around the turn of the century, ran the latter half of its life with more carbon than that.
@@iadr Getting kicked in the ass mighta broken it loose, to then jam up.
I just can't wait for the "let's crack the head bolts loose" part 😂 love that sound!!
Much like the pre-GDI Lambda V6, this is an absolutely tough engine bolted into depreciation queens that owners never cares about. I honestly can't fault Hyundai for their current ways, as their owners didn't care enough to maintain their old Mitsubishi engines, continued not caring when they actually made some really rugged engines and attempted to rival Toyota on some reliability fronts, and now have just given up, making cars laser-focused on their "60k and throw away" cheapskate customer base.
Their roughly 2006-2011ish engines are well engineered and built engines that can withstand near-zero service and not break as well as a 2GR or MZ. The cars just never last long enough to matter.
You gotta let loose from time to time. Nothing stupid, just clear the engine every now and then, like we clear our throats. Odd analogy yeah but you get the point.
Definitely signs of poor fuel ran through this.
As the owner of the 5.0 version of this engine, thank you! I hope they are the same, I heard it’s the same block?
5.0 is GDI after 2012, no?
The Tau could run on regular gas. Hyundai's computer would monitor the engine and de-rate the performance. Hyundai even published separate power & economy numbers. I believe the same is true for their 5 liter V8 & their naturally aspirated 3.8 liter; IIRC, the 5 liter went from 429 hp to 375-ish if regular was used instead of premium.
Really enjoy the channel and the editing. Something might take three minutes, but you speed it up to prevent subjecting viewers to three minutes of bolt removals. Thank you.
nicely built engine , maintenance looks simple 👍😁
That is a nice straightforward engine design. The older KIA / Hyundai pre GDI engines were good. The newer GDI stuff perhaps not so much.
My wife drove a 2007 KIA with the 2.7L V6, it ran like new at 150K miles, used no oil, transmission worked like new also. Alas, my kid totaled it and that was all she wrote. Who knows how long it would have kept going.
The 2.7l is a great engine mine in my tiburon has 200k miles and I drive it hard abd rev it past what the factory intended and its still running strong .
@@mg.2187The 07 doesn't have the GDI, it wouldn't even be the Theta II just the original. Explains why it's still running well lol
@@mg.2187 The Theta II was introduced from 2008 onwards but it wasn't the GDI version
If I may make an observation, having grown up working on the 'old' technology motors. Watching your videos it appears that these new hi tech motors actually run dirtier. The only time I would see that much carbon inside a motor was 200,000 + miles without an oil change and carburetor tuning completely for majority of those miles. Thanks for the videos
Nah. If you were around for the late 90's working on vehicles from 86-91 manufacture date- I'm talking early and mid generation 4.3 GM, Ford 3.8, GM 305/350 TBI, Chrysler/Mits 2.6 - they were all much worse than this by the 50-60% point in their lifespan. At that point I was doing tear downs- in fact much as Eric does, the difference being we were trying to do budget rebuilds for fleets and car lots. Quite successful in terms of quality, but it was a crazy low margin business. I left, but I think cash for clunkers did them in as a business model and that aspect of the industry had just been too weakened by trying to fix customer engines so *they* could profit- at our expense- to ever bounce back.
@@iadr I have to admit that when I got those vehicles they went straight to the junkyard, all the vacuum operated devices and the control valves made them not worth working on, lol
Yes and no.
DI and silly long oil service intervals have made "modern tech" look bad and added sources of carbon and dirt, but the core "old style" processes themselves are much cleaner and more efficient in modern engines.
The whole point of PCV, EGR, DPF is to recirculate crap that used to be vented out the exhaust, back into the intake
Tldr emissions tech bad, combustion efficiency tech good.
yeh, all the carbon being retained in stuff like oil and recirc systems and all of that was just being yeeted into the upper atmosphere. newer engines are burning purer fuels with detergents baked in, and doing a _much_ better job of it, they just look worse bc they do a better job at doing it _efficiently,_ and they hold on to pollutants instead of just shitting them into the sky.
and like Eric said, it's a 4.6 liter putting out as much _wheel horsepower_ in a genesis as a 6.5 liter olds super rocket could put out _at the crank with no accessories._ while getting what, 2x the gas mileage? 2.5x?
hard to complain about any of that when you can abuse the hell out of them on top of everything else 🤷
These are great engines, the V6 is very good too, i have 2 Borrego V6 with high milleage, and they're still running great and don't burn a drop of oil, the Borrego is a very reliable SUV, and you can have them for cheap.
I always feel bad for the engines owned by people that think oil changes are expensive.
Exactly...the typical Kia/Hyundai owner
I own a genesis sedan with one of these 4.6 engines in it. I typically stick to the old reliable 3k mile oil change, synthetic 5w-30 with a wix filter. Comes out to about $75 or so depending on price fluctuations for the oil and filter, but I’d rather spend that $75 every few months than to need an engine or new car. 😅
@@BiffBuffchest more CHEAP kia owners. Not genesis which is NOT a cheap vehicle. It's cheaper as far as luxury cars but not cheap like a kia
@@Genesis385 this is idling too long, not lack of oil changes
You look at the engines that they actually sell and they’re crap. Then this, they sell barely any and its so well made, so beautifully designed, so simple.
And very refined. One of the most smooth running engines I've ever owned. As smooth as my Lexus 2GR-FSE V6 engine.
I owned a 2009 Kia Borrego quite frankly it was the best vehicle I’ve ever owned. It never broke never nothing and I had 140,000 on it when I sold it and he just in a tuneup and spark plugs and it ran like a champ never had an issue.
I bought 2 kia spectras new, a 2005 and 2007. Both were great cars. I bought a new 2017 Hyundai Elantra , fully loaded, it just turned 100.000 miles last week. Absolutely 0 repairs, and 0 issues. In May of 2021, I bought a new kia K5 GT LINE with premium package. Very nice car, 26.000 miles now, again, no issues . The Elantra is now mostly used for my 78 mile round trip to work. I bought the K5 at just the right time, paid MSRP, and qualified for thier 0.0 intrest promotion! SWEET!
Growing up around auto mechanics, I find your videos awesome. Excellent content.
Gotta give your car the Italian Tuneup from time to time to keep it all clean!
No officer I wasn't speeding, I was doing a scheduled 7000rpm service
I had a 2011 genesis with one of these motors briefly at the end of 2022. I say briefly because a knock developed in the engine shortly after and when I dropped the oil to see what was up, I had a ton of glitter in the oil filter and in the oil itself. Seriously looked like an oil painting with how it was mixed in. Didint keep the car after that and from what I understand. You gotta use 5w-30 in these, the manual even said you could. 5w-20 is what the oil cap says but that is way to thin for these engines
A well designed high quality engine - too bad it had to end its life this way.
I have the Hyundai 5.0 engine and watching this video was a joy. I hope one day you can obtain a 5.0 GDI from Hyundai or Kia and possibly compare both 4.6 and 5.0 if you still have this engine nearby. I think it will make for an interesting video and to hear your thoughts on the two propulsion system.
not only a good flooring it to clean out putting some good quality injector cleaner in gas tank a couple times.. On my gas cars which tend to be hyundai when the tank gets to 1/4 tank left i put a whole bottle of techron in and drive it like i stole it for a couple days.. hard acceleration and some WOT runs.. you can start to feel it getting cleaner,, then when i fill up i put another bottle in tanks and run it normal.. techron and seafoam are two of the best for cleaning out injectors and carbon deposits in gas engines.
PS don't know how you film and post so fricken fast. it's a job on both ends... THANKS a million.
Audi 4.2 goes from 300hp to 450hp depending on model year
Those are direct injected engines. He specifically mentioned that at the beginning. This Hyundai V8 was port injected.
Looks like a pretty well made engine.
The thing about Hyundai is they tend to over exaggerate their engine power outputs. And it gets worse when you compare to the Germans who do the opposite.
I'm glad you brought that up...Americans have short memory. It was a scandal several years ago. Me

97 accaod wagon
I have a 2012 Hyundai Azera Limited that I bought in 2016 with 33K miles on it. It's just shy of 100K as of now 5/13/24. That vehicle seems to have it own kind of engine that's not in other Hyundai's, Genisis or Kia models or so I've read from many articles and forums online.. It's a V6 GDI 3.3 liter I'm very curious whether you've ever gotten your hands on one if those. I'm also on top of its maintenance needs and do full synthetic oil every 6K miles. It's still going strong, smooth and quiet!!!!! Other than a new engine mount last fall (I live in southern AZ) I've had zero issues. It still runs and looks like new. It's a pleasure to drive. Great road trip car. 35 MPG highway.
I bet the owner ran 87 octane, instead of 93. That and no where near enough Italian tune ups
Thanks for all the great videos happy fathers day enjoy your weekend with the family!
That engine, looks to have set outside, for a long time.
My borrego has this engine and is now cocking at 250 miles with no problem. Just replace pcv valve last week and found that i took out the original one.
I'm a mechanic and love seeing what goes wrong with these engines.
This is a beautifully designed engine.
it's a shame it had a premature death, likely due to never getting to stretch it's legs.
You mean, doing the ole "Italian tune up" may have saved this engine? MAYBE! Thank you for another GREAT teardown, Eric.

@@alro2434 I understand american for this: you got a lot of immigration from us back then, and mainly from the south Italy and lower classes. Now you've to know that Italy is *heavily* different between north and south even now, Milan compares to NYC like Enna (Sicily) compares to some rural Alabama town. And back then was even worse: around 1900 four millions of Italians (mainly from the poor south, where Mafia has its home) came to the US. Back then the illiteracy was around 35% in the north of IT and up to 92% in the south. You got those 92%... And also the temper is VERY different, and you got those that weren't afraid to use a knife if you looked their woman...

All US Presidents Related to this One King? | SELECTED or ELECTED? | reallygraceful (UA-cam)
In a post-American revolution society, it would seem like the divine rights of kings would be a distant memory, but is the reality really so? Do certain bloodlines still hold power within our current government system? And if all US presidents are somehow united in blood, does that mean our leaders are really elected by the people? Or does that mean they’re selected by few?
All of the US’s “elected” Presidents have been descended from Holy Roman Emperor Charlemagne via King John of England. Only Gerald Ford, who was not “elected” into the Presidency, was not related to King John and Charlemagne. Charlemagne was crowned “Holy Roman Emperor” by Pope Leo III. Queen Elizabeth in the UK was, and King Charles is, also descended from Charlemagne.
The Vatican, not "We the People", decides who will be President.

The pendulum will soon swing from the far-left (Marxism) to the far-right (Fascism) as the solution to a growing Communism problem in the US.

The state must gain glory through constant conquest and war. The past was glorious, and the State can be renewed. (Make America Great Again, right?) The individual has no value outside of his or her role in promoting the glory of the State.
