The Lambda engines are one of the best engines from Hyundai/Kia. Very reliable and no horrendous recalls or engines failures unlike Nu or Theta. They have a reliable and simpler design. They also have better build quality as all the Lambda engines are built in Korea. (Nu and Theta sold in US and Canada are built in the US). These engines were found in the Veracruz, Genesis, Genesis Coupe, Azera, Entourage, Sedona, Armanti. These engines can go up to 200k without any trouble. Overall great teardown. This engine could have lasted a lot longer.
I have lambda 2 3.3 in my 2015 Santa Fe. so far no issues at 148 000 km. changing oil every 6 k km since new, synthetic only. still good power no noticeable drop in fuel economy.
I have a 2017 at 115000 it just started consuming 1.5qt every 1000 miles. And has a ticking noise on coming from passenger side any thoughts or opinions would help
@@calvinpeterson3203 Oil consumption + ticking noises means an engine rebuilt in your near future. You can do it now while the engine is still in one piece or wait until it dies and replace the whole thing. But who knows, maybe it will go for another 20 or 30 thousand miles before something happens.
@old_dan hyundai just extended that motor and year for our car to 150k 15 yrs and good news they will replace motor but only a 12k 1year warranty. Which I kind of disagree with I would at least like the difference of 150k from our 115k but better than paying 9k for the motor.

My 2012 kia sorento sxv6 has 305,000 miles, no internals replaced to my knowledge, purchased it 4 years ago at 243,000. It still runs and drives like a 190,000 mile chevy 😭💜 bless its heart
Bullet-proof engine. I drove a 2006 V6 Sonata for 255K miles with only changing the PCV about 80K miles. No other parts replacement. Currently on a 2014 Genesis 3.8 V6 with 218+K miles with a PCV replacement at about 75K miles.
Nice. I have a 2018 Stinger with the 3.3 twin turbo Lambda 2 and I hoping to get at least 150k trouble free miles. So far it's been a daily driver for the last 6 yrs and nothing but basic maintenance.
Hey Speedcar, rebuild that engine. Make a series other than your teardown videos. Show us how you would clean the engine, check tolerances and do a modular rebuild. That would be enjoyable to watch. Everyone else is rebuilding old tractor engines and it's getting boring, we want to see a newer engine rebuild. Have a buddy build an engine run stand, hook up a harness, and run it, that would be really cool. Great videos, I've learned a lot, thanks.
The types on engines he gets it would cost too much and take too long to clean the engine. Most people would take a few parts from the engine, clean then, for theirs, for repair. Well on normal cars, not Korean garbage.
@@greggc.touftree5936 Korean garbage eh. Did you not watch the video? Have you not seen any other engines before? What sort of data sets are you cherry picking from to label anything from Korea as "garbage"?
This engine appears to be very well designed. What irks me is the lack of preventative maintenance on this engine and this can be seen by the heavy staining left by the oil. The excessive use of sealant is a worry and the use of a wrong head gasket speaks volumes why this engine failed. All the bearings were good and the oil ring was also unblocked. So why did the engine overheat.....poor ongoing maintenance by the owner.
I believe this is the 3.5 lambda, the best of them. No gdi stuff. Our 3.5 has 190k and running great, no oil consumption, no timing issues. The plastic oil housing, the plastic fuel rail and the oil pressure sensors are prone issues. Overall its much better engine than i thought for a kia.
What's interesting is that the MPI 3.8 doesn't have the plastic coolant transfer pipe. The intake manifold is all aluminum as well. And the knock sensors are on the outside of the banks. I have cracked one of the plastic fuel rails before though haha. They have to be treated with care.
The video I've been waiting for. Many thanks bro. These engines are very reliable and can run more than +500k km maintenance free. The only drawback is the intake manifold tends to fail rearly and cause loud noisy sound
Would you say that the issue with these engines comes down to bad maintenance? I keep hearing that the dealer recommended 10k mile oil changes is what keeps these from lasting. Makes sense since the design does seem very simple.
As a Kia master I see the back bank head bolts pull out and strip the threads on the block, this causes the head gaskets to go. Normaly the back bank goes. This is just the 3.3 v6 on the newer v6 3.8 I have yet to see this failure. If you have a 2016-2018 sorento with the 3.3 there is a TSB that will replace long or short black depending on how bad the failure is for the bolts stripping out. Extended warranty is 10 years 180,000 miles.
Other than that, take care of it and they hold up really well, keep the coolant and oil fresh and they will go 200k and I have seen a few in the 300k mile range with minor problems.
@@doodledo5226I had a 2018 sonata..I got a recall for a knock sensor software update. Then I got a letter from Hyundai giving me a lifetime warranty on the engine. That’s only for people that did that recall.
Great video man, I own a 2018 Kia Sorento V6 with a Lambda II GDI engine. Getting look inside a Lambda II engine and hearing about the heat and oil burning issues. Makes me think more frequent coolant flushes and more frequent oil changes as the car gets over 100k miles would be a good idea. Also did you use your wifes shirt to wipe up oil at one point? No many shop towels have a floral pattern lol Great video!
8:54 "They're known to overheat & they burn oil" Not so sure about that. Well engines don't just "overheat" As long as you keep an eye on the coolant all will be fine. One thing for sure, they use some rubber which I believe has to be bio-degradable on the upper radiator hose. at 70k miles/5 years, my upper radiator hose got a slash on it. Parts for this engine are not readily available and needed to be ordered, so I cut the hose in two pieces and connected it with a fitting. When the hose arrived I did not changed it over because well, it was working fine. Guess what, less than a month down the line, another slash appears. The rubber was just basically expired. Anyways, with a new aftermarket hose its already been years no problems. Zero oil consumption on my end at 129k miles, and I change my oil every 3k because I do a lot of high-speed highway cruising 130/140 most of the time and this engines don't come with an oil cooler so the oil gets degraded pretty quick, and its a GDI too.
Thanks for the video and the explanation/opinions on all the aspects of the engine. We're looking at replacing our Toyota with a new Carnival, but never owned a korean vehicle before and was wondering about the reliability of this class of engine vs a turbo 4 cylinder. I realized that I'm running a bit on hope that Hyundai/Kia has maintained a lot of the methodologies shown in this 2012 engine to a 2024/2025 (in short, more metal, less plastic, especially where it counts like the oil hose under the intake, timing cover, etc.)
I have a 2008 Sorento on 2” spacers with the 3.3l Lambda 1. It fkn rips. Sounds way sportier than it’s probably supposed to. I tried the FRAM XG9999 or whatever full synthetic filter and it caused the oil to drain back into the pan so only use OEM i guess if you’re reading this. It sounded even sportier and picked up better after I got a new oil filter :/ I love this rig. It’ll go where some jeeps have had a hard time going, but I did have to replace a steering rack, both front steering knuckles, tie rods, ball joints etc

Not really true, the similarities are basically none. This only applies for the"G6CU" engine which was essentially a 6g74 flipped around. Everything was identical except on the mitsubishi motor they put the bell housing on the left/ timing components on the right, whereas hyndai took the same engine literally and put the bell housing & timing components on the other side. Everything is just different, the bore and stroke, the all aluminum construction, the timing chain instead of timing belt system, the variable valve timing, the cam bucket design, pretty certain the crankshaft and rods are cast instead of forged as they were on the 6g7 series, open deck design vs closed deck on the 6g7 series. What else can be said, literally a completely different engine.

As you said, " a pretty simple engine design". Not a bad looking V6 either! And I know, you know the correct way to use a crescent wrench. Hate those things! LOL
Maybe it was because we had the early 2014 sorento, but it had gone through 2 lambda 2's and we sold it after getting the 3rd motor.. all were replaced under warranty because they all developed knock. The first engine made it till around 100k and the second -shit you not, didnt even last until the end of its breakin period... When we got the third engine we already wanted to sell the car but i noticed that it was also experiencing the same "knock"/ tick at startup that the other engines did.. apparently this is just the way the VTC system works on these POS engines and oil needs to flow before it goes away.. but like i said, every single engine i had developed knock from normal driving (and not just at startup)
How did you donate the cvvt assembly I’m in doubt because I assembly new phasers but it didn’t run well and the cold start still noising and check it again and the intake phasers blown off
I don't think there's any Lambda engines with both DI and multiport. I have a 2018 Stinger with the Lambda 2 and it's DI only. I wish Kia would've put the dual system like other manufacturers have done. 😞

There's a recall for the 2024's Lambda II V6 engine replacing the engine sub-assembly. NHTSA Recall No.: 24V-077 & Manufacturer Recall No.: SC296 “2024MY Telluride Engine Valve Spring Chronology.” Certain 2024 model year Telluride vehicles manufactured from October 1, 2023 through December 6, 2023. The engine valve springs may break while driving due to fatigue cracking as a result of damage to the springs during manufacture by the supplier. A broken valve spring may result in a loss of motive power. In rare cases, a hole in the engine block may occur due to a broken valve entering the combustion chamber. All owners of the subject vehicles will be notified by first class mail with instructions to bring their vehicles to a Kia dealer. Kia dealers will replace the engine sub-assembly. Kia will reimburse owners for repair expenses already incurred pursuant to Kia’s General Reimbursement Plan filed May 10, 2022
I don't blame hardworking folks who dare NOT touch any Kia or Hyundai vehicle. With the massive bill they shouldered from the engine failure/engine fire fiasco plus other major safety recalls, guess who will foot the bill eventually?
>Reliable. >Recalled for head bolts tearing out of the block and stripping the block threads. Costs $420 for the repair kit, and $5000 for the labor to do the job.
The overheating issue is very common BUT its mostly from the radiatior fan connector burning up and causing the engine to be fucked Overall those are the most realible engines hyundai and kia ever made.
Modern engines are technological marvels, but are they "better?" Define better. They make more power, with less fuel, achieving better efficiency. But is that better? The engines are much more complex, much more prone to failure, and more expensive to produce and more difficult to repair. In other words, there's more to it than just efficiency for efficiency's sake. I love engines and playing with tech ideas on paper. That doesn't mean all these ideas are good ones.
Do people actually adjust the cam buckets on these? I feel like you’re talking thousands of dollars for something that’s got not real drivability concerns.

When we got the third engine we already wanted to sell the car but i noticed that it was also experiencing the same "knock"/ tick at startup that the other engines did.. apparently this is just the way the VTC system works on these POS engines and oil needs to flow before it goes away.. but like i said, every single engine i had developed knock from normal driving (and not just at startup)
What kind of oil were you running? Did you ever run it low?
@@speedkar99 was never low but we did have to follow the warranty 6k mile intervals
Also these were the early GDI v6s
Awesome engine for the price; looks decently made.
It sure looks simply designed
Based on the huge number of Kia Tellurides that have been sold since 2020, you'll have plenty of those engines to do an autopsy on in the future.
Would be awesome
What causes 2012 kia sedona 3.5 oil leak from main seal?
How did you donate the cvvt assembly
I’m in doubt because I assembly new phasers but it didn’t run well and the cold start still noising and check it again and the intake phasers blown off
I believe you may be incorrect the new version uses both DI and multiport.
Are you sure for the v6?
I know the new 4 cylinder have both
@@speedkar99 I could be wrong
I don't think there's any Lambda engines with both DI and multiport. I have a 2018 Stinger with the Lambda 2 and it's DI only. I wish Kia would've put the dual system like other manufacturers have done. 😞
Don’t they have some pretty bad issues with head bolts being stripped/blown head gaskets ?
Yes this had a blown headgasket
Any videos of the Tau 4.6? Or is that the one that just never breaks down? :D 🙌
No it's hard to find cheap
Overall clean design, odd they still prone to major defects like head gasket leaks. Perhaps due to open deck design?
Yes. I think it's the head gasket
hey speedkar, can you do a kia seltos review once you've got your hands on one? we've got it brand new, overall I trust the atkinson engine but I'd like to hear your opinions about the IVT.
Check my Forte video. It has an ivt
Lambda is known for overheating? What's cause? Water pump failure?
Yeah but also the head gasket design
@@speedkar99 What is wrong with the design? It isn't just case of bolt not being torqued enough? If it's in fact shit gasket what rough mileage would you recommend a preventative gasket swap.
@@TrollinCrazyRussian certain displacements of Lambdas have TSBs for head bolts.
The 3.8 has a MLS gasket and is high quality. Mine showed zero issues after a teardown at 90,000km. In fact, the entire motor showed very little wear. Save for the destroyed piston ring lands.
@@FonicsSuck whew that sound good. That's almost satisfactory coming from beloved Ford modular 2valve 4.6 in panther platform just plastic intake manifold replacement at around 150k alternator around same time. Steering gave out at 174k ish then got rid of car due to life circumstances not having enough time or money to find low mileage junkyard part. Wish I could rip out motor and transmission driveshaft and axle for some cool off road kart toy or high mpg ultralight car crazy power and torque to weight. Went in debt for Hyundai palisade for new job
In my dads 2010 santafe its been working for almost 155k kilometers and so far the only thing that went wrong and had to be replaced was the cvvts.
Were they rattling? The VVT gears?
@@speedkar99 well yes on cold start you could hear them for 1-2 maybe 3 seconds and it would go away. and as it goes with the usual car owner my father didnt care about the sound cause it would go away. he finally agreed to take it to a shop after like 8 months arguing.
Another PRIMO take-apart video Brotha!!! And as always,I always Love watching You take the engine's apart and EXPLAIN to everyone,exactly what the part is,and what it does inside the engine!!! That helps teach people that may not be aware of what a certain part is for,learn on why it's even there to start with!!! The BEST PART? Your wife handing You a delicious choc.chip cookie at the end!!! Lol. Thumbs up!!! : >)
Glad you appreciate it! It sure takes some effort to do this but I enjoy it, and the cookie treatment haha
Yes it does take time&effort,and we're all glad that You choose to do it for us all! Great job Man!@@speedkar99
Luckyly in my country, we never got the problematic Nu and Theta II engines. Most of Hyundai/Kia products here got the Gamma engine or their U/R diesel engine which are quite reliable.
Good
my colleague from India shares that his Hyundai diesel engine car was outstanding i think its pity Hyundai diesels aren't sold in North America!
Just did a Bank 2 intake sprocket on one of these.
How difficult is it in the car?
Not bad. It didnt take long for a tear down compared to the other engines
Yeah it's a simple easy one.
Hey i got the lambda II 3.3 twin turbo in my genesis g70, I want to change my headgasket and headstuds but I can’t find any information anywhere about how to do that or torque specs etc, any help??
There's a recall for the 2024's Lambda II V6 engine replacing the engine sub-assembly.
NHTSA Recall No.: 24V-077 & Manufacturer Recall No.: SC296 “2024MY Telluride Engine Valve Spring Chronology.”
Certain 2024 model year Telluride vehicles manufactured from October 1, 2023 through December 6, 2023.
The engine valve springs may break while driving due to fatigue cracking as a result of damage to the springs during manufacture by the supplier. A broken valve spring may result in a loss of motive power. In rare cases, a hole in the engine block may occur due to a broken valve entering the combustion chamber.
All owners of the subject vehicles will be notified by first class mail with instructions to bring their vehicles to a Kia dealer. Kia dealers will replace the engine sub-assembly. Kia will reimburse owners for repair expenses already incurred pursuant to Kia’s General Reimbursement Plan filed May 10, 2022
I still want to see the veloster N Theta 2.0T engine (performance pack one)
I don't see how much different it would be mechanically
@@speedkar99 yeah I'm pretty sure it's just a tuning difference
What bolts size you use to mount to the engine stand? Thanks🙏🏻
YESSSS IVE BEEN WAITING FOR THIS
You have a Kia?
Fascinating! Love your videos.
Glad you like them!
It is a nice tip.😎
It sure is!
Looks like a 2GR except for the thin timing chain
Yes very similar. The 2GR has rockers thought
First! Your videos are awesome and funny!
Glad you like them! Thanks
Lots of piston in that water. Yeah
Haha you caught that
This looks llike a great engine design aside from the plastic 6 bolt mains is impressive.
Plastic 6 bolt mains?
Great video!
Thanks!
Me gustan tus videos son muy buenos👍
You are welcome
I don't blame hardworking folks who dare NOT touch any Kia or Hyundai vehicle. With the massive bill they shouldered from the engine failure/engine fire fiasco plus other major safety recalls, guess who will foot the bill eventually?
>Reliable.
>Recalled for head bolts tearing out of the block and stripping the block threads. Costs $420 for the repair kit, and $5000 for the labor to do the job.
The overheating issue is very common BUT its mostly from the radiatior fan connector burning up and causing the engine to be fucked
Overall those are the most realible engines hyundai and kia ever made.
Yes more reliable than their other engines but still prone to head gasket failure
@speedkar99 what's the cause of the head gasket failures ?
Fantastic Video!
Thank you very much!
This engine seems to have a lot of similarities to the Nissan VQ
Modern engines are technological marvels, but are they "better?" Define better. They make more power, with less fuel, achieving better efficiency. But is that better? The engines are much more complex, much more prone to failure, and more expensive to produce and more difficult to repair. In other words, there's more to it than just efficiency for efficiency's sake. I love engines and playing with tech ideas on paper. That doesn't mean all these ideas are good ones.
everything feels so over engineered these days, i say emission standards are really pushing us to the limits.
I feel like better means it lasts longer and is made of higher quality materials
Does not look like you washed hands before eating the cookie 😉
I took off my glove. 🤦♀️
3:20 Peyronie's disease. Poor guy.
I did a short block build on this engine. Haha
How did it go?
It went well. The engine had horrible oil consumption problem and the customer got a goodwill repair from Hyundai. Customer got lucky for that.
Also, when I was tearing it down one or two head bolts weren’t that tight either. Funny how you ran into the same thing.
Headbolt blown out is well known issue.
Ah so the tip of the water pump must be why the oil and water streams crossed and blew the engine!
Ugh
@@speedkar99 "never cross the streams!" I love that movie 😆
Thanks
Welcome
regular "plastic" could not handle the heat that is composite
Notification SQUAD!!!🔥🔥🔥
Thanks
Really hope whoever worked on this engine doesnt call themselves a qualified mechanic. That amount rtv everywhere is criminal
It's crazy!
I have a gen 2 lambada
Way too much RTV as I'm seeing a lot rubber gaskets and grommets missing. Maybe Subaru can learn from this
I think this engine was worked on by a sloppy mechanic
please start a gofundme for a scrapped 1uz or 3uz, I want to see your take
I'd love to get one but the easiest way is to buy a $2000 scrap car.
In a future design, they're planning to use the engineers' wives' old dresses as oil baffles.
Hahaha
Do people actually adjust the cam buckets on these? I feel like you’re talking thousands of dollars for something that’s got not real drivability concerns.
If you're doing a headgasket job and the cams are coming off then yes it'll be worth it.
Would love if you responded to my comment on your vw Tiguan video.
Ok
@@speedkar99 the only reason why the Tiguan was misfiring in your video was because you had the dipstick pulled causing a vacuum leak.
How does a guy so young know so much?
lookin like a vq eh
Kinda. More like an MZ series Toyota inside. The VQ has a different chain Setup.
Not the worst kia design ive seen
It's a pretty good, simple design.
Headgaskets are what kill these.
any solution for it?@@speedkar99
To Hyundai and kia, it's not bad.
Yep. Not as bad as their reputation perceives
Nice
👏😍
Thanks 🤗
Brilliant video
👍
SHARP Speedkar99

Thanks from Toronto Canada
Oh yes the horrible theta 2 just got done rebuilding one
RIP
replaced by a turbocharged bicycle ... 🤣
Yep. It's probably gonna be the fate
I once saw its repair. That was horrible.
They buy there head gaskets from Subaru…
Haha good one
Great video. Really well done. Sorry about your wife's dress, hopefully your kids outgrow some more clothing soon.
Haha
Yep I have some baby clothes waiting for the next teardown
I hope the Mrs didn't spot her summertime dress when she handed you food. No use this time of year in any event, an ideal oil catcher. Was that a rock cake or a scone?
Cookie lol
Like I said before, KIA engine, design to break, KIA, kill in accidents. KIA owners are not going to be happy with this but hey, value king right?
Yes
Kia/Hyundai keeps you in engines to tear down.
And Subaru
Girlfriend has the 3.3 in her 2015 Sorento EX V6 and the eldest sister has this same engine in her 2014 Sorento SX V6 until it took a shit on her that led her to say no more Kias‼️
It may REMIND you of Toyota, but it’ll never be as reliable as Toyota. Korean cars, while better than Fiat, just aren’t great overall.
Agreed.
Failed? Don't tell me you're one of scotty Kilmer's students with a bunch of clickbaits
This guy is nothing like Scotty.
If you watched the video, the engine actually failed. Big time.
@@speedkar99 sir, that's only one engine. Most of those engines barely have any problem. But hey, if that's how you want to make your youtube, i don't blame you.
@@boots7859 you got alot of those guys out there. Scotty is like a senior to them.
Landa not Lambda
So semi junk
If it's not overheating it's fine
You never disappoint! Excellent work! 😀
Thank you
