What's inside a 500,000 km Toyota Engine?

- Ever wonder what's inside an engine with over 300,000 km?
In this video we teardown a Toyota Prius 1NZ-FXE 4 cylinder engine from a 2004 Toyota Prius. The engine features drive by wire throttle body, cast aluminum intake manifold, aluminum head and block, dual over head cams with variable valve timing on the intake, an accessory belt for the water pump only, and a timing chain powering the two camshafts.
The Prius engine is the detuned version of the 1NZ that makes less power but is more efficient because it runs on the Atkinson cycle.
After removing the oil pan, timing cover and valve cover it is evident that after 17 years and 300,000+ miles the engine is tarnished dark on the inside. The oil control rings are clogged, and carbon buildup is evident on the piston heads. The bottom of the sludge and oil pickup is lined with sludge. The intake system has carbon buildup from the PCV system. In conclusion, while there is no evidence of mechanical wear just due to high mileage, the lesson learned here would be to take care of the oil system in your engine if you want it to last longer than the rest of the car.

Not enough comments about the awesome editing on this video. So many mechanics’ videos show you every bolt coming out, every gasket removal from start to finish, every repeated step. You show us the first one, pause to explain what is important, and move on. Thank you so much for all that extra editing work!!
Yeah I’ve never seen better pacing in a mechanic video. Humble Mechanic and Eric The Car Guy have some decent ones, but too often it turns into a fucking blog. Speedkar gets it done, and I hope he has it in him to keep this style up for a long time to come!
He is a great teacher and know what need to be explain clearly!
Too many comments about it, i counted 488 of them.
I would also like to add a generic comment about how good the edit is
Agree, this was almost professional editing. Really well done
This engine lived on in the Yaris Hybrid in Europe until mid 2020. That makes 23 years in production for Toyota's first shot at a Hybrid power train. Simply outstanding.
It was on the Prius C in the USA from 2012-2018. I have a 2013, bought it last year before car prices went crazy in America. Seeing videos like this makes me wonder why anyone would buy something other then a Toyota, especially a hybrid car.
It will be difficult to replace - the Toyota ZR engines are very nice and they don't burn oil but they will not last as long as one of these NZ engines.
@@zoidberg444 There really is nothing like owning an ancient Toyota and knowing that every drop of oil you lose is due to wiping the dip stick with a rag
Good for you, my 500k 4S engine both burning and leaking oil 1l/1000km😄 Probably needs a light rebuild someday
@@xkenny1995 Mine was like that too. I added some seafoam and mystery oil to the oil and gas. Fixed the problem in the first 500 miles. (Follow the instructions on the can)
Sold a 22 year old Civic last year. Original engine and transmission. Running strong. 500,000 miles
Nice!
Машина это как женщина надо не пропустить встречу и расставание . ...
Impressive up to a million
Honestly the D series civics were tanks. Not so much their brake lines though.
Is the body still intact? I meant by intact is no rust.
My '02 Prius died almost 3 years ago with just shy of 800,000 miles! Engine was still good, the hybrid battery died on it. I got the car with only 38 miles on it. Great car!!!
Can it be fixed with an overhaul?
@@christianphillipampoloquio6484 I'm sure it could have. Just didn't make sense financially.
Oh man did u make a world tour in that car?😅
44000 miles per year!
5 trips from Portland, OR to different places on the east coast and back. Also weekend trips from Portland to Salt Lake City. Yes, lots of driving!
Yeah Toyota has some of the best engineering and mechanical friendly assembly. I learned on Peugeot, then worked on Honda, then in an open garage with all kinds of cars and now on Toyota and everything is so easy to work on and they really have quality parts its like night and day compared to other brands.
From the work you have done on Peugeot. What can you say about this brand from your expirience?
@@SunStarcz Their absolute garbage tbh. I really dont like hating but spare your time and money and get something else.
Almost all Peugeots with +100k km (around 65k miles) leak oil at one seal or another, or all of them.
There's honestly nothing better than japanese brands.
Yeah maybe you pay a little bit more in the beginning and parts are also maybe a little bit more expensive but in the long run youre having much much less problems and its definitly going to be cheaper.
We have Toyotas with 30+ years and 300k km and they look better than some peugeots with 50k km.
@@benistingray6097 Thank you. You have only strengthen my cureent opinion. Once I will have enough money to buy a new car I am definetly getting a Toyota. Right now I have my first car and it is and 98 Peugeot 306. So far I cant say complain because it is my first car and I got it for free but still. Good to know that I better not buy from Peugeot again.
@@benistingray6097 Hi, same question as before but with Honda? How much difference is there between Toyotas and Hondas? From your experience
@@MHNK77 Hm their both really good but i would still rate Toyota higher.
We had more "non service" work with Honda, mostly small stuff that broke, for example the Honda Jazz always had problems with the EGR systems clocking up.
Also i would say Toyota is more servicable. The way the engineers build stuff makes working on them super easy which in return should make repair bills lower just because the work is done faster.
But take that with a grain of salt, i havent really worked on Honda in the last few years so things could have changed.
Also im only working on Toyota for maybe a year so i dont have the same experience as with Honda.
You cant really do wrong with both of them.
Best is to do your research on problems with the specific car and engine your interested in and avoid problematic things.
That was the break in period, good for another 500K
Dude....the cylidners are not even round!
@@hussamjamil4980 It's been properly sized to the pistons for optimal performance!
Agree. Fill with high detergent petrol and slap in some good quality oil and filter and change every 5000km most of that sludge will be gone.
these cars were probably scrapped because of battery issues, rather than the engine problem
I put just shy of 400k miles on a slightly diff varient (1nz-fe). These engines are gutless but reliable as frig! Worst part is my 1nz didn't even die naturally! I hydrolocked it on a rainy day and flooded roads :(
I believe Toyota has a formula for how much power is enough to make thier engines last. Scotty Kilmer covered that. Less horsepower, the longer it'll last. Hence why exotic cars don't last. Too much power and heat destroy an engine.
Aww man. Good engines though.
Aww man it could've went longer!! I only had 64k miles when I totaled my Yaris with that engine. Sad day.
I too have a 1NZ-FE in my ‘07 Yaris with 271,000.
Drive it every day since I bought it with 18,000 miles.
I’ve changed the oil at 10,000 mile intervals with Mobil 1.
Currently uses a quart every 10,000 miles.
Only replaced the alternator and starter.
Best car I e ever owned !
@shawn 1nz-fe got some kick to it and it's very reliable. If you want gutless then buy a Toyota corolla with 1.8 and cvt 😂🤑.

Always nice to see how a good engine looks inside. My daily driver is a Volvo 940 that has 550000km on it, and it runs like new. My hobby car is a Citroën DS from 1973 with over a million km on it, also runs like new. Some of todays manufacturers have a lot to learn from my old cars and of course any Toyota.
most manufacturers now build it strong enough to last a certain amount of miles, not too much so that the consumers buy newer cars more frequently. also because technology became more advance, they don't have to overbuild the engines.
@@jakejakedowntwo6613 Good thing that Toyota avoids doing that.
Those Volvo’s are insane
The pressure on car makers to lower emissions, fuel usage and increase power are the causes of unreliable engines. Direct injection, CVT, EGR valves, soy electrical wires, turbo..all unreliable. The Koreans almost got there, but their engines crap out due to piston slap.
La mia Citroen Berlingo 1.9 d aspirato del 1998 oggi ha 320000 km ed è perfetto
Your videos are like being in a college automotive class. Excellent.
Thanks
6:22 "Looks like the plastic still held up" unlike VOLKSWAGENS!

VW simply is CRAP
@@joskd8491 Yet some people love those pieces of crap unconditionally. 🤷♂️ Specially in places like Portugal, Spain etc. Go figure. 🤦♂️
@@tiagofigueiredo2529 Portugal and Spain don’t have freezing temperatures, plastic has nothing to fear. Up north German plastic just disintegrates, not just VW.
494 000km on my 2nd gen Prius. It's so freakin reliable. Just warm up/cool down your engine and change oil regularly, then the car is gonna last forever. Current oil consumption is 0,3l/10 000km, which is pretty acceptable I guess :)
WOW😅
awesome reliability.
What kind of oil did you use? Are you a sporty driver?
My 4.0 i6 intec burned zero oil at 400,000km
@@Elaba_ so, 3 days ago I passed the 500 000km mark :-D
oil change every 10 000km, I use Mobil 1 5w30.
I always let the engine warm up properly and never push it when its not on perfekt operating temperature. My Prius gets pushed once it´s warmed up, quite often over 150km/h+ on the highway. Sometimes, I need my car to go that fast, that´s why I don´t use 0w20 oil but 5w30. Seems to work fine.
Kudos to the engineers that design these things

And no thanks to the people that are negligent and ignore servicing, they'd rather pay for an expensive engine replacement than for a $100 oil service. If you think education is expensive, try ignorance.

Keep up the good work
those are Tartar from years of carb and sugar abuse diets..
Toyota's are just amazing. I have seen many vehicles with 500k kms. No other makes comes close.
My wife and I both have Chevy Tahoes that have over 300,000 miles on them and only ever changed alternator and water pumps. Granted we are both mechanics and keep up with maintenance but they still run like new with plenty of power and run hard daily. No sludge or leaks. Hers does burn alittle oil but isn't as meticulous as I am
@@christbennett429 Granted bigger vehicles will last longer. But Toyota s small cars r also awesome
My dad's prius (2006) also had done 350k miles before giving out. Brilliant car.
batteries died on her?
@@fidelcatsro6948 the car got hit, and caused problems with the engine & battery limiting it to slow speed.
@@MrAceekidd thats sad..my condolences to the loss of a reliable workhorse
I took the valve cover off my 200k+ mile Tacoma 2RZ-FE engine and it looked spotless.
My uncle was the previous owner and he kept up with maintenance and oil changes.
These Toyota engines will last forever if maintained.
What's left in that engine? Another 190,000 miles. Proper maintenance keeps them going a long time.
Nice...
How you got this engine?
From junkyard?
are you sure about the kilometers in this engine?DID YOU CHECK.?
IF IT IS TOYOTA ENGINE
ITS OK TO HAVE 500K.
Now this days we cannot believe anybody 😪!!
Yep. Lots of life left. Solid build quality. Just needed some more maintenance
i think partially because it has been in hybrid vehicle and you can easily divide the mileage by half
This isn't just proper maintenance (in fact, someone was going way, WAY too long between oil changes), it's excellent engineering and build quality. Even the best maintenance can't make the worst engines last.
I really appreciate for showing the piston and piston rings closer, so we can see what happens with the engine by time. The engines suffer oil consumption early, mine does it on 126k miles, oil changed at every 5-6k miles. I now try to clean it from the inside with special chemicals through oil and with full synthetic oil at every 3k miles or a bit less
Marvel Mystery Oil is a good, cheap, cleaner fyi. It’s not harsh like some other crankcase cleaners.
Our 2006 Prius has 275k miles and still running strong. It went through years of East Coast weather and towed my motorcycles to the track. Great build quality.
That looks really good for 500,000km, someone looked after it, I’ve taken apart some Mazda 3 and 6 engines and the cam shafts were caked in old oil at 230,000km.
I have a 2006 Tacoma 2.7L 5speed manual. Just passed 200,000 miles and works great, doesn't burn a drop of oil.
However, it leaked oil, and I've replaced the head cover gasket. The old one was brittle. Old rubber parts die first. But with a bit of care, Toyota engines go forever.
Great job, my friend, love your teardowns. I just bought a 2010 Matrix with 353+++ km, manual, for 500 bucks Cnd. Runs like a clock, even the ac works. Just had to put new tires on it to get the safety. They are honestly indistractable. I'm gonna drive the crap out of it and see how long it goes.
Take care of the body above all.
Matrix is a good car. My brother had one as his first car and was closing in on 300K. Ran mechanically fine when sold.
@@fun_ghoul The body is still in pretty good shape, I'm gonna spray it with Fluid Film before the winter.
@@speedkar99 my friend had a Pontiac Vibe (Toyota Matrix) the odometer when to 299,999 miles. So who knows how many miles it had haha! I guess Pontiac (GM) thought that was a pipe dream.
220,000 miles - you might get another 200,000 out of it with a bit of luck and as long as you look after it.
In Northern climates its the rust that gets these. My daily here in England is a 15YO Toyota Yaris with 230,000 miles on it and a few years ago I had to do some rust treatment on the underside around the rear suspension, the rear axle beam. I just got a donor front suspension for mine from the scrapyard for £150. Really low mileage stuff, spotless. Here is to another 200,000 miles and 15 years.
Awesome quick video explaining almost every function of a car engine. Thx for the huge teardown! Awesome channel
That's an interesting view: bearings all nice and clean, but those piston oil scraping rings... I have a 2010 Lexus GS 450h, the 2GR-FSE with 356.000 km. I reckon it would look similar inside, perhaps less sludge, as there is some oil consumption, but runs fine.
czcams.com/video/wafZjkY0H_E/video.html
@@sin-sinner7192 no
Seems consistent with my 2008 prius with 287k miles. Used 1qt of oil every 1500-2000 miles
Hlo senpai big fan here
Just use Eneos Sustina 5W30, which keeps the engine very clean. The Toyota 5W30 sadly is a very bad quality oil (but their 0W20 is probably the best among the 0W20 oils). I couldn't find the TDS for the Toyota/Lexus 5W30 so I am not sure if that is better than the Toyota 5W30 but you don't go wrong with Sustina.
Wow, ironically my ‘09 Prius inverter pump took a dump today. Easy to replace, but really expensive for a simple water pump. But at 250k, the engine runs brilliantly. Thanks for the video!
The simpler the better; I like the internals! The sludge inside is not that bad for a 500,000 Km (310K miles) engine.
Yeah it's very simple which I like. I don't feel confident about the sludge though, given the mileage it's acceptable
But my car at 130k miles is absolutely silvery clean. 17 years old
Impeller is metal, unlike some VW 🤣
I have a 1.8T, I felt that
😩😩😫😫
What engine are you referring to? I have a AEB 1.8T, and honestly I don't know if the water pump impeller is made of metal or not
@@STFDVC1 probably plastic. Mine is an AWP and has a plastic impeller, I'm replacing it with metal soon.
my 2000 1NZ-FE is at 589, 000 km and overheated due to bad fan relay sensor, im doing the head gasket now and hope the head is not cracked but the motor is beyond outstanding, thanks again for your excellent videos and production.. God Bless

@@speedkar99 this video came on some big car forum, thanks for the good job, please give your opinion about how each engine can survive in kilometers
The engine is so well made. Although a hybrid car uses its engine less, there is a lot of start/stop on the engine. So Toyota must have figured out how to prevent wear on start/stop situation in order make the engine last forever.
Starting only causes wear due to low oil pressure and cold oil being ineffective. Once the motor is up to temperature, starting it again only wears out the starter motor itself.
@@grahamek86 and a hybrid doesn’t have a starter motor. The secret is: they start on the drive engines, permanently connected through the single planetary gear that makes up the transmission.
Extremely simple, mechanically.
Thanks for this upload, I was waiting for this vehicle motor breakdown, cheers!
Your knowledge is so good about your engines! Hats off to you.
Thank you for this video! Very good lesson to learn some engine knowledges.
Crazy the build quality. I wonder how some of the engines of today are going to hold up long term
they wont hold up. extended drain interval. sp oil lacking proper additive package and 0w-16 will kill them.
Yep, all metal construction
just after the warranty expires
@@thisismyalt9010 that’s weird in Saudi Arabia the owner’s manual recommends 5w-30 with 5k km interval
@@FerasAlhawas yep and that is wrong. look at your oil pressure. engine needs a minimum of 10 psi per 1000 rpm. anything over 80 deg f needs to run 40w oil. hot weather makes the oil shear faster and breaks down the elastic modifiers even faster. if you can find 15w-40 thats what i would use. shell rotella t5 15w40. still has lots of calcium and zinc in it to protect the engine. they pulled the zinc out of t6 under 1000 ppm. no zinc no long lasting engine.
There were definitely some extended oil drain intervals on this engine, the OCI and oil type would be interesting. Tough little engine! Thanks for showing us!
nice, very straight forward explanation
People can be literally tearing down a 500k km engine, saying it's in good shape, and still be like "ew a Fram filter"
fram filter and cheap oil??? so, not bad
nice video i have a 1NZ-FE in my xb im currently at 282x after watching your video im definitely going to be taking off that oil pan and cleaning it and the oil pickup screen thanks.
Good idea!
Gonna need a toothbrush, lol
Wonderful to watch. Thanks for the experience.
I bought a used 3 year lease return 2012 Rav4 (base model) for one of my daughters back in 2015. I liked it so much I ended up getting another used 2014 lease return Rav4 (base model) for my other daughter. Both vehicles have been absolutely fantastic.
This man is a mechanic God. Wow, I am shocked by the insane amount of knowledge and expertise. Amazing!!!
Most if not all workshop mechanics nowadays are called technicians. There's a big difference between a mechanic and a technician. Mechanics can take an old damage part and repair it from scratch. Technicians simply replace damage parts with new ones ie strip and assemble.

Great video as always! You should do a teardown video of a 22R engine, those things are indestructible. In my country there are a lot of those old pickups and never fail.
Probably can't find one. They're still all pushing those pick-ups around and no one wants to give them up.
Great video. I own a 2005 Prius with 193K miles on it. Owned it since 14K miles and changed oil with full synthetic oil and expensive mobile 1 filter every 5K miles. Transmission fluid changed every 75K miles and coolant changed every 5 years. I have replaced the traction battery, Throttle body and a 10 dollar radiator hose. Paid 14K in 2007. Still laughing all the way to the bank. Very happy with the longevity of this vehicle. I do not plan to sell ever. Drive until failure so large that it is financially not able to repair. Great to see this teardown.
Really? $3,000 battery and you’re laughing to the bank?
@@morrisl7 i paid 2800 and sold my used battery for 1000 and returned a completely dead battery from the person who paid 1000. My cost basis is 1800 so yeah still laughing.
320,000 miles on my ‘06 Prius and running. In the past I didn’t even put oil in there at times and when I checked there wasn’t a drop of oil left and also zero coolant lol. Still kept and keeps running. Toyota is just indestructible.
Would love to see the cleaning, reassembly and reinstall on this
Its amazing that this engine is in such good shape with so much sludge on the oil pan. It seems to me the owner put off some oil changes over time.
Seems to be the right choice of oil changes for this engine though. He wouldn't have been much happier with paying for more oil changes.
wow, that camshaft look in real good shape
This was excellent, 5*

Beautiful video!
I think it's clear how important is to do a correct oil change. Regular intervals, good quality oil and filter. With a proper maintenance it could go 1,000,000 miles.
Another thing that I noticed: that car didn't probably drive in the rust belt... Here in Michigan the exhaust manifold would be rusted solid by now, the bolts wouldn't come out so easy.
No, cars are not designed to last 1 million miles. Wear happens regardless of oil changes.
@@justayoutuber1906 : Did you ask a Toyota engine designer??? Recently a Tundra reached 1,000,000 miles. Also I've heard of Tacomas teaching that. And not only Toyotas.

I've seen some cars with high 200 000 km and the valves and guides are still perfect no movement
Nice! Mostly Hondas?
That shouldn't be an issue with most engines used in regular life.
rkan2 well with old cars by that milage valves and guides were junk , partly due lower quality oil
@@bigears4426 Yes - OE oil change intervals and oil types should be followed of course. Not many (western madr anyway) engines since the 90s wouldn't go to 300k with not many issues if you changed the oils per spec.
Toyota engines last. Great story: acquaintance had an 80’s Corolla. Drove in it for many years, then the oil pressure light came on. Drove to the dealer upset about the light, “fix it”. Appeared that he had done over 60k Mi (100k km) without ever changing and checking oil.
They filled her up and off he went.
Wow
I remember my buddy got an early 80s corolla from a police auction years back. Turns out it had 400k kms, still drivable. Those old corollas must have been able to take a lot of abuse.
I remember almost 30yrs ago older lady came to my friends shop complaining her Tercel died. She drove for 60-80k km without changing oil. When my friend ask her when was the last the oil was changed, she replied: I thought the Toyota is so good and don't oil change. He rebuild the engine and she became his regular costumer.
I have a 1NZ FE whit 340 000km and still running so smooot awesome
Another awesome video! I sometime just watch and meditate since your videos are so relaxing and interesting. What's the best defense against the sludge and clogged piston drained plugs that you noticed???? more frequent oil changes...maybe add a oil additive that cleans sludge?
Wow! What an educational video! 😃👍👍👍
After having a Prius Mk. 2 for over 13 years I'm driving now a Yaris Hybrid (XP13) with the same engine.
I'm thoroughly convinced of this well designed and simple engine.
Are the crankshaft bearing inlets made of lead❓
Modern engine bearings are made in multiple layers. The back is steel, which is covered with a thin layer of either aluminium/tin alloy or copper/lead alloy. If copper/lead is used it will in turn be coated with a very thin layer of either tin/lead alloy or pure tin.
It didn't look that dirty. But I am comparing to when I cleaned my 2002 vw jetta tdi at 300000km. I was amazed it had gotten any air into the engine at all.
what a great video, and you're very knowledgable

You are indeed a dissecting DOCTOR.
Sure
In my experience, almost any engine approaching 300k will be burning a little oil no matter how well its been maintained. I'm referring to valve seats and piston rings. I've got a 1mz-fe with 260k. Synthetic its whole life and changed every 6k. It needs about a half quart a month if driven hard and over 80 mph. The valve cover gaskets are famous for eventually leaking on that engine too. They were just replaced and no leaks for now. A few seconds of blue smoke if started a few hours after an aggressive drive.
Valve stem seals will often go before rings or seats. Then oil will be sucked down the valve guides by manifold vacuum, even if your rings are perfect.
you are absolutly right, we owned a corrola verso for 15 years, it was still driving good but we needed the oil just as often as you fill up with gasoline
Huh, despite the sludge and tarnish, this engine looks good enough to put on another 500,000 km!
Yep, it's mechanically sound.
To bad the sludge will kill it

See my engine flush video
Looks pretty good! I believe it could run another 300k with no major issues aside from burning oil.
I expect it to be cleaned up and set in motion again? 🙂
Not after breaking one of the timing tensioner chains. This vehicle is going to be junked, it was totaled somehow. Maybe the catalytic converter was stolen. The catalytic converter in even the oldest Prius is the #1 sought after thieves because they have the most rare metals out of any other car brand due to Toyota trying to go very low emissions with the Prius. It's so expensive that replacing the catalytic converter costs more than what the vehicle is worth especially with that mileage and many states don't allow aftermarket catalytic converters.
@@SI0AX The Prius gen 2 catalytic converters are still getting stolen in EU so the oweners are replacing them with aftermarket ones. They are holding up pretty much after a few years and they are not even expensive as OEM ones.
You can get inexpensive tiny cameras with fiber lights that you can hook up to a laptop on the USB port if you want to see further into things.
Great video, amazing tech, thank you.
I'd like to see an engine with 300k miles that ran synthetic oil.
Maybe the best edited videos in this genre
Question for Speedkar99 or anyone. I follow you and used ur video on my timing belt replacement video for my 97 Lexus es300 IMZ 3.0 motor. It’s been about almost 3k since the replacement. My question is I’m getting a almost like a higher pitched noise coming from front cam pulley. Any idea what causes this? It almost sound like the pulley is loose. I did take off the cover and inspected it and everything looked good. I used Asin oem parts from rock auto like you did. Could the belt be too tight ? The idler looked fine that was my first theory and the noise is coming from the front cam pulley and I didn’t change the seals. I have looked on forums nobody seems to know but suggest have it inspected. I don’t have the cash for it lol it’s why I done job me self. Any help be greatly appreciated!
Use the stethoscope or screwdriver to pinpoint the noise while it's running. Could also be your accessories as well
If the belt tension is too tight, it can whine like a supercharger belt. Go find a video about a Dodge Hellcat, inevitability they will be driving it hard and you can see if that is what your timing belt sounds like.
How does the hybrid factor into the mileage doesn't that allow the IC engine to not run as often and run off the battery or am I missing something here. Or put another way to the hybrid factor of the Prius skew the mileage high when the mileage really isn't that high on the IC engine?
Some prius are struggle to keep warm in the winter times because of the engine didnt make enough heat.
@@KarrasBastomi Which would contribute to the oil tarnish and sluge
I mentioned at the end of the video. You have to outweigh the time spent running vs the wear of how many times it's been started and stopped
I enjoyed the video sir thanks alot.
I learned a lot from this video! Thanks!
The 'shims' cannot be adjusted, the gap is measured and the shims are replaced with corresponding sizes according to the gap.
Yes, thanks for that
You put yuck on the thumbnail? I have never once encountered a high mileage engine that was clean internally
Encounter more high mileage engines.

Yes yuck, why? The sludge at the bottom was dirty. But nothing out of the ordinary for 300K miles
I have a 1997 Camry with 5S-FE engine with 349K miles and still going strong. Toyota makes great cars.
Amazing video. Subscribed.
Could you imagine if they actually took care of the engine with proper and quality oil changes how many miles this engine could have gone? I'm HUGE on oil changes on my cars.
Lmao ikr? I have a 2011 Prius with 134k miles on it and it doesn't burn any detectable amount of oil. I get it done at the dealership every 6 months, and thing has never had a single issue. Toyota just builds engines different
I’m inspired to do an engine tear down this weekend! Do you recommend I use my grandmas old toothbrush or my brothers?
Choose someone you don't like
Love your video. Feel like a tutorial in details. Very informative.
Glad you like the teardown
The more engine disassembles I see, the more I appreciate my four cylinder Mazda engine for it's simplicity and serviceability.
Agreed. Mazdas keeping things simple
This engine had a lot of start stop cycles, thus more wear then running same temperature all the time. So i dont dont agree on the comments it hasnt run the mileage, it has run even more like short distance city traffic!
Yes and no, the start stop is hard, but it runs more at higher speed than stop and go in traffic when hybrid kicks in.
It looks a lot better than a direct injection would with 1/5 the mileage.
Agreed
More videos like this! I love long life Toyota tear downs.
Very informative video, thanks! Any information on the Prius battery condition?
No new engine will ever go this long anymore. Manufacturers sacrifice the engine to meet emissions now. This is what extended drain intervals and thin 0w oil is all about.
Economy, emissions and warranty. That's all that matters
Nice video , thanks for sharing . 👍
That's a really nice engine. What are you planning to do to the engine after video? Rebuild or use it for another video? Love the video btw
Great video, feel much better about my 2008 now with 160k miles lol the hybrid battery just quit sadly.. new one ordered it will be here next week 👌🏻
Wow Speedy! 300K + Subs! Awesome!
Best ever explanation!
Toyota never die. Amazing.... :) Love toyota engines.
As far as the sludge, these maintenance reminders from the mid 2000s caused Toyota lots of issues. They were still on conventional 5W30 and many of them on factory settings only called for LOFs every 7500 or 8000 miles. IIRC Toyota did an update to lots of cars from this era to shorten the intervals. Possibly related to the 2AZ oil burning.
