I've been tearing down engines on camera for 2 and a half years! Search my channel to see what I've torn down. Here's a few recents:

Todays engine is one often thought to be impossibly reliable, but like any engine ever made, the general public has found a way! A 2010+ Toyota Prius 2ZR-FXE. This is a 1.8L Atkinson cycle aluminum 4 cylinder that makes just shy of 100hp on its own. With the relatively low power output, you'd assume these low stress engines would run for ever but really, these engines are kinda notorious for this type of failure. That's why used engines are $2000-3000 even with higher mileage. The high price of a used engine usually means there's a significant demand and a relatively low supply of good used engines.
Why am I doing this? I own and run a full service auto salvage business and part of our model is dismantling blown up engines to salvage the good parts to resell. We do not rebuild engines, but we do supply parts to those that do!
I really hope you enjoyed this teardown, as always I love all of the comments, feedback, and even the criticism.
Catch you all on the next one!

I TRULY HOPE YOUR REQUEST HAS BEEN COMPLETELY SATISFIED

Get schooled scrub 😂
Literally woulda took 5 mins on google tops but you had to make a fool of yourself

You must hate Toyota's, but sure. You have provided 'facts'. What do you recommend for reliability? Audi? Perhaps BMW
@@hariranormal5584 I actually love Toyotas and I think they’re amongst some of the most reliable Japanese branded cars you can buy. I own two.
That’s why when they have a notorious problem it really stands out.
If you want to take what I say as an attack on the brand, I can’t help it. 🤷♂️
@@hariranormal5584 I mean look at the vehicle next to my name… it’s a Toyota 😉
"It's a reliable car" means you shouldn't be stranded by it or need to throw lots of money at it. It doesn't mean you can completely forgo preventative maintenance. A lot of people have a hard time with that distinction.
For "a lot of people" there might as well be a hamster-wheel under the hood ;)
😂😮😂
To the comments so far.
Even reliable engines need the oil checked or changed
Its electric, really the gas motors cheper then the batterys are
My kids prius battery failed under warranty the bill was over 2k for a rebuilt unit i believe ( seems the hampster was out of nuts)
No seriously its not a bad car, but you cant forget you have to matain the gas motor like any other car.
Gas mileage is friknig outstanding if driven right.
I think they should have just used a air cooled 26 hp diesel engine that runs on any fuel type to charge the battery and the battery for motion
The motor is a jet like the Abrams a1 tank but exhaust gases are reburnt and it only runs to charge the battery, heat off the motor can be used to keep the car warm in the winter and start on its own even without the key in a parked outside mode it uses detection to find the spaces its in or if its outside, its also a plug in hybrid so if its plugged in its always warmed up ready to be driven, no snow on it.
The body is aluminum/fiberglass and not ferrous materials so it cant rust its water tight dust tight and water dust nor anything else can get inside it parked
If there's a flood it just floats.
I know from experience that Toyotas are extremely popular among penny pinchers who buy them with the idea that you can save by skipping the maintenance on one. And on the rare occasions they do maintenance on it, it's the cheapest place they could find or just by themselves with very little clue about how to do things.
Old Toyotas here are often absolute ticking timebombs due to years of neglect and half assed repairs.
“How do you blow up an engine at 56mph in the left lane?” I laughed out loud😂
It’s so true. Prius drivers are some of the slowest and most annoying on the road and their engines still blow up because they’re poorly designed.
@@sharedknowledge6640 You were referring to the drivers right? 😆
@@sharedknowledge6640 Not only Prus drivers. All Toyota drivers . Always below speed limit
@@sharedknowledge6640 I had a teacher in high school with a Prius. He would go 55 in a 40 and pass students in the center turn lane.
@@sharedknowledge6640 I don't drive that way and I own a Prius. 2nd gen and I've had mine up to 130 mph. It's a weird thing too. At about 45 the aerodynamics of the body starts to really show. I've gotten on the highway, got up to sped and then 10 minutes later I'm doing 80+ and no, I wasn't "giving it the beans" either.
As a Taxi driver, I drove the Prius for 14 years. Never had one blow up. In fact, it was one of the most reliable cars I have ever driven. Considering what we put them through, that's quite an achievement!
Proof that regular inspection and maintenance works!
The only reason I bought one was because the taxi drivers in Chicago were driving them to 300,000 plus miles. If they can take the abuse of taxi style driving, my hwy driving was going to be easy on it.
What did you do for .get long millage
I was following a taxi one day,a Camry hybrid, it was blowing clouds of white smokefrom the tailpipe so bad that it was like driving ina fog for those behind.Not sure what the issue was, but one friend haa Camry hybrid and his problem was OIL CONSUMPTION @200 Kms, that's roughly 120,000 miles. a liter of oil per 1000Kms was his consumption, or a quart per 600 miles.
My 2010 started to go around 250,000. I pulled the head and installed a new head gasket, water pump and timing chain.
Also I think one of the most overlooked things is the pcv tube hiding under the intake manifold, completely clogged.
Back together and now with 25,000 miles on her still not burning any oil like it did previously. Thanks Gaskets Masters for some helpful tips.
it exploded🤣
My Fiat diesel (bought with broken cam chain) has been fully rebuilt and now doing fine. But the head and inlet manifold were severely clogged with soot. It had been driven ridiculously slowly leading to spot deposition and excessive loads on the cam chain. Pretty carp for 120K but Brits do 1/2 the miles of USA and mostly in town. These particular engines have sacrificial rockers so valves usually survive.
That's how they go. Did you have oil in your intake manifold? PCV is the culprit usually
You have to clean out the EGR cooler, EGR valve, and small passages from the EGR system in the intake manifold roughly every 80k-100k miles. At that same time change the PCV valve and also install an oil catch can so it doesn't get plugged up like yours did!
@@jimsgaragetoys4963 I just replaced my intake all together. Cleaning out the small passages within the intake is almost impossible. Better to just replace it and it takes less time
I’m sure you were having LT3 flashbacks with the dipstick. But the forklift practically lifting the engine by the dipstick, is a whole new level.
The dipstick resistance are going too send a terminator from the future too handlenthis guy
It's all fun and games until your dipstick gets seriously stuck.
I don't know why he even bothers with an engine stand, the manufacturers make the dipstick tubes that tight for good reason.
The dipstick is stronger as the connecting rods?
@@Swedish_John_Wickj
Our 2013 Prius V courtesy car made it 350k km before the head gasket went. It was burning quite a lot of oil at this point. Found a 130k km used engine and it's back up and running. Still a great vehicle. Still on the original hybrid battery. Wish Toyota would bring the Prius V back.
I think that wagon body with the new style would look pretty sweet. Sadly I doubt we'll ever see it as it seems if something isn't labeled SUV or crossover, nobody wants it. I'd love a Prius V Prime with AWD.
I've found out, that 300k km is the magic number for head gaskets. Usually the engine starts to fart exhaust into the coolant, and the temp needle starts acting really weird.
215,000 miles really isn't great for a toyota
Exactly. Mine blew at 340k
Answer for head gasket failing is water pump. After 200k km they aren’t efficient and engine get overheated if use at higher speed or oil hasn’t been changed in time. This electric pomp need to be changed every 200k km
It's simply amazing the amount of torque that MG1 can put onto the engine. You can fully hydrolock one cylinder and the motor will spin the engine over regardless, leaving the rod in all sorts of fun shapes. On this engine, I would expect low oil to have caused the #3 rod bearing to spin, which lead to the localized overheating on the crank and subsequent failure.
I don't know where that engine comes feom but my Prime like to turn oil into mayonaise during winter so i buy the lacks of lubrification theory.
Water from outside in the oil? Strange. And its not coolant? @@marc-oliviercabot3380
not true. There is a clutch assembly pack with dampening springs in the torque converter to prevent this.
the clutch is always engaged but will release at a certain amounts of torque. Look at assembly diagrams of a prius Hybrid you can find this safety device.
I'm stunned, I never thought I'd see you save a WATER PUMP 🤯
He made $50 !
My mechanic for my Prius made it very clear to me that any time I run my vehicle more than 65 mph the oil consumption goes way up. Some sort of mechanism to keep the engines running long and happy at higher speeds and higher rpm. That amounts to about a quart of oil every 1000 miles or so 75mph. You have to check them often and keep them full of fresh, clean oil. If you only drive around town the oil level basically never drops. Mine is closing in on 300k and it's been a happy engine.
I would think that if you only drove around town the gas engine would rarely get used. Maybe that is why around town driving didn't use oil. But hwy driving, where the engine is constantly running, the engine is showing it's true colors as far as oil burn goes.
Check out these 2 service bulletins that Toyota put out for the 4-cylinder engine they were putting in the Corolla and Camry cars for a few years. (T-SB-0024-11 and T-SB-0094-11) They were burning a quart of oil every 800 to 1500 miles after 50k of use.
You've GOTTA be kidding me!
@@InquisitiveSearcher I think you're confused about what a Prius hybrid is, versus what a Prius Prime PHEV is. A Prius engine gets used around town, because you can't plug it in to charge it, and it really doesn't get far on battery alone.
A Prius Prime on the other hand, like my 2017 Prime, can go as far on electric after you charge it, as it can go on 1/2 gallon of gas. The EPA says 25 miles, but for me it's usually more like 30-35 miles, sometimes 40 if at modest speed. Yep, that means that I normally get 60, 70, even 80mpg on gas alone, without dropping the battery state of charge. My last 43.0 mile round trip to a grocery store yesterday got me 248.4mpg, and would have been more if I hadn't forgotten that the defroster (hence AC) was on for the first several miles. 43/248.4 = 0.173 gallons .... plus of course the 6.6kWh of electricity I had charged it with. From experience, I know that the $0.79 of electricity I used, saved me 0.50 gallons of gas, and that using only gas, I would have therefore used 0.673 gallons and averaged 63.9mpg despite the defroster mistake and all warmup losses (which also happened while burning the 0.173 gallons I actually used).
I love that every time I get home after using up my EV range, I can "make a half gallon of gas" at a cost of $1.58/gallon. And it never knocks in EV mode, so that's really comparable to premium gas, for $1.58/gallon. And via the deal offered (to everyone, not just EV/PHEV owners) by my town through an alternate electric supplier, my price of "EV gas" isn't going up above $1.58/gallon until the summer of 2026 at the soonest.
Maybe I just got a good one, but my 2017 Prius Prime has 111K miles, made two 8000 mile round trips out west and has not used even 0.2 quarts of oil on either trip. And at no point did I go as slow as 65mph on the highway for any extended period.
In Texas, where the speed limit was 80mph, I set the cruise control on 94mph for a full tank of gas. But that gets me about 34mpg, so I actually prefer 84mph to get 42mpg all day long when I'm covering a lot of ground. In another unnamed western state, where there is a lower speed limit but plenty of places where you can see 10 or 20 miles ahead and behind, I hit the governor at 104mph (where it doesn't sputter, just acts like you set the cruise on 104) and set the cruise at 103mph until approaching a curve or somewhere a cop could be hiding. In yet another place, I was at full throttle or under braking during a 4000 foot drop in altitude down into a canyon, and a 4000 foot climb back out of it, on a road that looks like a caricature of twists, turns, hairpins, and short straightaways between switchbacks. It's an awesome car to push hard. Much, much faster cars simply can't run with it under those conditions, and those who try, end up with actual smoke coming from their brakes before they give up.
On one of those two trips, I also spent 17 days in southern AZ in temps up to 119F, and left the engine on 24/7 all month, except when filling the gas tank and checking the oil. It didn't use any, despite the engine running 700 hours that month.
I use 0W20 Pennzoil Platinum (sometimes Ultra Platinum, not always), for whatever that is worth.
I don't notice any difference in toughness or oil consumption, between it and a 2005 Prius I had earlier and actually didn't part with as a spare car until I'd had the Prime for 5 years. Both sure seem bulletproof to me.
@@EfficientRVer : Well, regardless as to if I am confused between a Hybrid and a Prime, I think you'll agree that the info that the dealer is giving to @abpob6052 about expected/normal oil burn is a pile of horse manure.
If you read up on those 2 service bulletins I listed, of which Toyota put out years ago for another 4-cylinder engine they made, you'll find out that the problem was that Toyota was using a piston with out enough oil pass through holes at the bottom of the oil ring slot. The excess oil in the oil rings would carbonize and then prevent the oil rings from working at all. This left lots of oil on the cylinder walls that would get burned up so the engine went though a quart of oil every 800 to 1500 miles. Toyota would give the customer, free of charge, a short block with the new/updated pistons but the customer had to pay for the labor of putting it in the car.
The rate of oil burn that @abpob6052 talked about in the original post just sounds so very similar to what was happening in a 4-cylinder Toyota engine years ago. Maybe a similar problem?
Most of the people who drive a Prius don’t know that you have to check the oil and change it on a regular basis. I watch your channel religiously. I’m a retired heavy duty mechanic and enjoy watching the carnage.
We have 35 Priuses, many over 250k miles and a couple over 300k. We have been cycling them out over 5 years and never had one blow up. Head one head gasket, a few leak oil from the timing covers and oil changes are every 5k miles. Never had a battery go bad, even in our 2005 models that do have over 300k. Most reliable and dependable vehicle I've ever seen. Electronics can be finicky in some. Mostly shift modules.
What business do you guys use these in?
May I ask why you have so many?
@@kinglangren @dertmatyui utility locating. Most of our guys are hard on vehicles, stop and go environments. Typical work day is 10-12 HOURS, 200-300 miles, cars never get shut off. They have been battle tested. We might consider the Ford mavericks now since they are leasing the hybrid system from Toyota but we need to find out if Ford did what for always does, replace metal parts with plastic.
Well maintained they are bulletproof. Personally however, i need to do an oil change every 1-1/2 months during winter as the oil never gets up to temps and gets loaded with water. From March to December it's mostly ok but December to March i do like 2 oil changes just to flush the water.. I'm considering putting a sandwich oil cooler to actually act like an oil heater so it would get up to temps faster during winter months..
@@marc-oliviercabot3380 That's all true, oil, water and achieving a long engine life don't mix.
I was surprised to hear Eric say 222,000 miles is early for an engine failure.

Just got back from the local Autocross. Seems like watching an engine tear down is the next logical step of the night.

Good on ya. Killing cones, and hopefully not con rods.
I have driven my 2013 100,000 miles interstate @ 80+ mph. Top was 105 and no oil consumption at all. Amsoil ev. 6 months, and Lucas fuel system lubricant each tank of gas. Runs great!
Eric,
I think it'd be really interesting if a motorcycle engine found its way into your shop. I know your primary focus is on cars, but maybe a grenaded sport bike or Harley engine may find itself in your vicinity one of these days. They aren't too much harder than car engines to yank apart, and 99% of the time, they're way smaller than your typical car engine. Lots of cool mechanisms and features set them apart from car engines too. Maybe some channel viewers are curious about bikes and how the engines work, and I bet they'd be really happy to see something way out of left field on the channel. I know i would ;)
Look back thru his list. A few months back he did a Victory engine.
Anything will fail if you fail to maintain it long enough
To be fair, if it takes a hammer, chisel and a fork lift to change the oil, I don't blame the owners.
@@CheezeCracker Actually the fork lift is standard protocol and specifically mentioned in the Prius owners manual.
@@LongBoy.0 well, at least that says a lot about Toyota, VW didn't warn me about pulling coil packs
As Mark Novak likes to say: "Do the maintenance!"
I drive a Subaru, and it gets a lot of miles on it, because it's my daily driver and I have a 42-mile commute. But...I don't redline the engine unless I have to (it had happened) and I'm careful to get the oil changed on time whenever it's due for a checkup.
@@CheezeCracker I own a 2008 Prius. 210k miles, original battery pack. Oil changes 3k or 6 months. I don't have that issue with the filter. That is either a problem with the last instillation, lack of oil changes or it rusted from being outside.
I could have gotten that dipstick out in a much shorter time, but the way you did it is WAY more epic and it will now be the way I do it from now on.
Do my spark plugs the same 😂😂
That tickled me too!
Diesel injectors....
50 ton gantry crane with sawzall-cut access hole through hood?
This is one of the best videos to date. Fork lift appearance simply to check the oil, that's something I havent seen before. While checking the head gasket the compressor kicks on, a compressor test. "Perfect timing" indeed, and fantastic. So after much consideration I believe there are more jokes in this video than there were piston nuggets, and that oil pan looks like the bottom of a fryer at a bad county fair on closing night, so you know it was packed with burnt nuggets, but somehow still not quite as many. As always this is another fantastic, fun filled, action packed hybrid edition teardown. Great content.
I drive a 2005 Prius just crossed 200k miles. I had an 07 before that, both fantastic cars, easy to maintain, easy to fix things, timing chain lasts forever. The 1.5 liter is more durable that's for sure and I'm not missing any pep. You'd have to hold a gun to my head for me to ever buy the 2010-2015 Prius. Somehow that 1.8 liter blows up head gaskets too 🤔 Yea try making sense of that. You'd think an Atkinson cycle would be lower on compression but they increase the ratio so the Atk cycle compensates. Idk why they bust head gaskets tho, it's crazy and it happens to at least half of them once they hit 200k miles. No sir, I'm riding my 2005 til the wheels fall off, or until the 2016+ model is affordable. 2023 model looks great but I can't afford one until 2040 😂 or I hit the jackpot.
Props to the dipstick! When you have to tag team it with a forklift, you know it was epic!
My son has a hybrid. It's not a Toyota, but I've asked him about oil changes and he goes years between oil changes. He blew me off when I told him he probably needed to change it more often. Oh well. It's his loss when it blows.
Send him to this channel especially if Eric has done a teardown of the engine in his hybrid???
His attitude is so mind boggling. What is it about oil changes that the younger generations hate so much?
It really depends on which car he has, if it’s a plug in like the Volt he may only be putting a thousand miles on the engine per year and changing the oil when the car says it’s time. I do mine yearly on the Prius and at 330k so far it can’t be hurting it, no glitter on my filters so far.
@@906MediaProductionsoil goes bad with time, certain additives do not stay dissolved in the oil with time
@@user-vk2cd9qw7i correct, but if it was causing a major issue it should have wiped my engine by now considering the average car would be scrapped at 2/3 this mileage.
I love your postmortem inspections of engines. It's amazing how much you can learn by tearing into these dead engines!
I loved the video. I own a 2014 that I've drive about 140k in 6 years. I feel victim to needing a head gasket. I proactively replaced it at a costly coin as it was consistently hard starting, blowing the white smoke, and probably used just a few ounces of coolant a week. What I wished I would have done in hindsite, was see how long it would have gone, but I'm not a gear head and I couldn't get a consistent answer on what would have happened had the head gasket blown completely. I can definitely say that I did the 10,000 mile oil changes religiously and I never checked the oil *until* the dealer casually told me one time "bro, your oil was low today. Be careful." Not their fault, but I do wonder how low it was during other oil changes (always the dealer). Oil is cheap, engines are expensive. Now I know. One question that I don't know that I've ever found the answer to... why do the burn oil? I'm asserting that if you check the oil regularly, don't let it run low, and don't let it go 10,000 miles- you'll be fine.
That dipstick removal was gold!
We need more mention of pig mat and angry parts removal with hammers and prybars !
I had a 2007 Toyota Corolla with a 1.8L engine and a C59 transmission. It was a great setup with plenty of power and as long as you kept up with general maintenance, it would go forever. My only complaint about the transmission is that the input seal is internal. I replaced my clutch, flywheel, rear main seal, and input seal all at once because I’m not a fan of doing any of that again. I had to disassemble the entire transmission. And it wasn’t an easy one to do. Worst of all, AAMCO won’t touch a C59 internal. They’ll replace the whole thing but they won’t replace an input seal. Toyota makes great cars but sometimes the design makes you wonder. Anyways, sold it while it was still going strong at almost 190,000 miles.
I have a 2010 Prius, and because of public knowledge of this engine being an oil-burner, I meticulously have checked the oil as long as I've had it. It never burns a drop and is now at 252,000 miles. I'm not saying this to "defend" my Prius, but because I'm curious as to why mine has been so dependable and near perfect, while this engine has a reputation of being the opposite. Even more so, because my car is not a garage queen or grocery getter. My previous vehicle was a Silverado Duramax 4x4, and I've treated my Prius nearly the same (off-road access trails, overloaded hauling, trips through the mountains, etc...). I'm paranoid that something bad could happen at any moment now. But every oil change (I do it myself), the dipstick shows exactly full, just as when I previously filled it after last change. And the oil is nice pale golden color, looks like it doesn't need to be changed.
Did the oil burning problem start at the end of 2010? Were ALL the engines from 2010 to 2015 the same, built at the same plant? I'm really curious to know if I have a ticking time bomb and the inevitable is coming at any time now.
I had a 06 Prius. Very reliable. I changed oil religiously every 5K. Checked oil level anytime I put fuel in it. First 150K it never needed a top off between changes. Around 200K I would have to add a partial quart of oil between changes. After around 235K I was having to add a full quart or a little more between changes. By 300K it would need about 2 quarts between changes. It was still running when I sold it with 340K. Point is what you say is true about regular maintenance. Any car will eventually wear its internals to the point of using oil. Also these engines do not hold much oil so you have a very small margin for error. Overall the Prius was the most trouble free car I have ever owned.
the cause for the P2 oil use at higher miles is oil coke formation on the piston rings.
I had a 2011 Prius and never had any issue with the engine. I took care of it correctly, which isn't generally what happened to engines that make it to Eric's video.
Oil changes are one of the easiest things to do.
How many miles did you put on it?
@@edwardspaccarelli5944 Sold it at 135k
I heard the problem was they used low tension rings round 2011.
I don’t often disagree with you, but in this case I think you got it wrong. I don’t think it was a low oil situation at all. Looks to me like an isolated failure to cylinder 3 caused it to spin the rod bearing which caused the failure. The knock went ignored while that material went into the oil packing the pickup and filter and damaging the pump before probably lifting the bypass and pushing some of that into the other bearings. There is wear and scoring on the bearings but not nearly enough to scream lack of oil to me. It also doesn’t follow the general progression of lack of oil, ie the bearing condition get steadily worse the further down the oiling system you go. Not much scoring in the top end as well.
Like I said, to me this looks more like something happened to that rod, maybe a plugged crank passage, that caused the bearing to fail in over a short time. It shed bearing material pushing it into the oiling system and continued to run without operator intervention until the rod bolts let go from overheat. The crank then came back around and hit the rod ripping it out of the piston pin bore and ejecting it out the block.
Holy crap, you did a request I wanted to see like… a year or so ago! Ran a 2016 Prius to 205k with no issues. Great car, drove it into the ground.
I've owned two priuses (Pri-i?) and a Chevy Volt. Not a single problem with any of them -ever. Anyone who is too lazy to check their oil at least occasionally, deserves what they get.
Really enjoy the humor and comments while you're dismantling the egines. Keep on truckin'!!
I don’t know if this makes me a geek are not, but I look so forward to your engine teardowns on Saturday night
The bend on that rod is impressive
Those Toyota engines sure make a lot of grunt at idle, huh?
It only had to break some thin & brittle aluminum, not a cast iron block too.
Pretty cool to me that it could bend like that without crumbling.
Electric motor makes sure that rod gets seriously bent.
We have a 2011 prius, gonna be hitting 200 k soon. No issues so far but I admit, it does seem to consume more oil between intervals versus our 2004 rav4 and 2002 tundra both at about 200 k.. my Prius manual even says it can consume 1.1 qt every 600 miles! I am well below that mark, but it is still something that's been in the back of my mind..
Thank You for showing and exploring my car's engine for me !!
Tech tip: you were using those channel locks backwards on the oil filter cap. Flip em around and the jaws will be oriented so that they don't slip away from the cap but rather the cap fills deeper in and gets clamped tightly. 😎👍
I had a 2010 Prius, paid $5K for it off the Buy here/pay here lot.
After Six months, the engine blew up, going up a hill it had gone up hundreds of times. I did keep track of the oil. I replaced the EGR cooler which was coated in grime, and I installed a catch can. A few weeks before the engine blew up, it had a bad misfire in the 2nd Cylinder. I got really good at removing the wiper cowel.
Then suddenly, it blew up.
Damn so what did you do to it? how many miles?
@@javajav3004 2010-2014 Prius engines have issues with piston rings causing oil burning issues. The piston likely cocked to the side, jammed in the cylinder causing the connecting rod to detach and spin creating an inspection hole
@@thatguyontheright1 "inspection hole" lmao i saw that on a plane once so you're not kidding.
How many miles was your prius at when it blew?
@@javajav3004 220k
i'm a livery driver, & my boss has 3 prius's... a 2010 & 2 2016's... ALL w/350,000 miles & more... bought ALL USED, about 2 or 3 yrs old & started them on AMSOIL... NO issues wutsoever... loaned the '10 2 hiz son-in-law, who then sabotaged air-conditioning while getting a "D" f/hiz daughter... got it bak & had a mechanic start working on it & he could NOT believe how CLEAN the inside of engine was... he changed AMSOIL Signature Series every 24/25K... NOTHING better than AMSOIL as far as i am concerned... 🤩
Ex-2010 Prius owner here. Something like 1 in 10 cars in Japan are some sort of Prius, probably because all the taxi companies switched to them. There's even a variation with a special over-sized body specially for them. They are so common that it was going to cost me more than the car was worth to fix the brakes suspension, which were the only things that really needed work after 9 years. I can't remember what mileage I had on it, but I think it was around 100,000k or so.
The early 2zr-fe engines did burn oil, but the piston rings were changed and the later generations of the engines do quite well. They used them up until 2018/2019 in Toyota Corollas. I own a 2019 Corolla with the 2ZR-FE - it's the last year before they changed to the Dynamic Force M20 engines. Toyota recommends 10k mile intervals and 0w-20. I run 5w-30 or 0w-30 for 3-5k miles. I know people who are at 300k or more on these engines. You need to take care of them and even the older ones before the piston rings were fixed will still treat you well. The oil in this engine and the filter look DISGUSTING. These call for 0w-20 which ONLY comes in full sunthetic. To get full synthetic oil that BLACK, you really need to abuse that engine. Someone ran this for WELL over 10,000 miles on an oil change interval.
I can't understand why so many people believe that you can treat an engine that way.
it's the egr cooler versions of the engine that have blowing up issues, that's not shared with corollas
The way the engine functions in the corolla is wildly different from how it functions in the prius, hence why they're so reliable in them but not the prius.
Toyota KNOWS (insider info) the 10 K is too much. But so many dealers give the farm away with free oil changes for like 2 years after purchase so Toyota obliges the dealers with an extended oil change interval to save the dealers money. seems stupid but I know this on good authority and no I will not reveal the source.
@@michaelbenardo5695 because they have no idea how cars work, all they know is "change the oil at X miles" a lot dont even know that X, because advice ranges from 3k, 5k, 7.5k, 10k which is a big range and the brain doesnt register it. and sometimes they forget. its a shame but a symptom of a overly busy life/society.
You're becoming my entertainment on Saturday nights! Keep up the great work
This engine is very reliable, if you do the maintenance required for it to stay in top running order. Most Prius owners never service and clean the EGR Cooler, EGR Valve, and the small EGR passages in the intake manifold are critical to keeping the engine running properly and not blowing a head gasket. I service can be expensive if you have a dealer do it since they just replace parts but if owners do the work themselves and clean the parts they can save a boatload of money and after doing it the first time the process isn't very hard to do. The early 3rd Gen Prius has a bad reputation because of owners not doing this service when needed. If done every 80k-100k miles you should be able to catch it before the EGR cooler gets completely plugged with carbon and the engine will remain very happy. This engine also responds very well when an oil catch can is installed. My wife loves her 2010 Prius and it runs like new because I do the proper maintenance on it.
the 1.5 was pretty solid in the gen 2, they're used a lot as taxi's here in the UK because they're ulez exempt, like any engine you have to get them serviced, oil is the lifeblood of an engine.
AH sprite owners manual checked oil, coolant & battery levels every day! Don't recall brake & clutch fluid and tyre pressure but were probably the same.
The 1.5 Litre Gen 2 Prius engine is literally bullet proof. I have mine serviced every year and I keep an eye on oil consumption.
Now I realise regular high speed runs will burn oil at 150k miles.
However it seems to use nothing during regular inner city commuting.
My engine runs as smoothly as it did when I first got the car over 10 years ago.
Shame about the Gen 3 Prius engine.
Eric showing how Jiffy Lube removes a oil filter was Priceless !!!
That dipstick tube has some major tensil strength
I'd have got Dad's old bolt cutters onto it! :)
Never checking helps 😝
One of those oddly satisfying sounds I've grown to love because of your channel - the crack/pop of the head bolts when they're loosened. Music 😁
My daughter has a 07 Prius with over 200k miles, yes it burns oil a lot of oil. I check the level every time she’s home, not fun to drive but it gets great gas mileage and my daughter loves it for that
"Blue" definitely needs a raise !!!! LMAO as usual Eric !!!! AND the fork lift was magnificent with the Dipstick !!!!
A 7.3 or 6.9 IDI international diesel from the old fords would be a cool video. Cool heads and cheap probably. Thanks and keep up the good work!
i do believe a 7.3l has been done
10 months ago. Just go to the 'videos' tab and click the 'search' button.
@@centauri61032 That was a Powerstroke. A 7.3 IDI has the same displacement as a Powerstroke and is also a diesel V8 made by International/Navistar, but that's pretty much where the similarities end. The 7.3 IDI is a bored-out version of the 6.9L. Both IDIs are completely mechanical, distributor-style injection pumps, no electronic controls. Until the last years of the 7.3 IDI, no factory turbo.
@@jasonhaman4670 Yup, you are correct. My error.
Those are pretty hard to destroy. Gutless but they're tough as nails
Great video, I didn't realize how amazing the Prius engine is! Thank you for an evening of chuckles too!
I just found your channel, and I love your style of teardown videos. Definitely the most interesting and informative channel I've seen that does these kinds of videos
Love your forensic analyst as you dissamble an engine. Great job and thanks for sharing your knowledge and time.
Yes this is one of my favorite things about this channel.
What carnage am I finding. 😊
you need one of those work tables the transmission shops use. the top is leaned slightly back with a gutter on the edge to catch all the fluid and run it into a catch barrel
I pretty much watch these for the dipstick tube battles. The Prius engine did not disappoint! Lol, keep the great videos coming.
I owned G1 and G2 Prius. No complaints, no carbonization issues, no oil burning/leaking. Seems like Toyota wants the '70s back.
There's a TSB for the dual-VVTi 1.8's burning exhaust valves, I just did a head on a '13 Corolla, but I have NEVER seen one of these blow up like that one. Insane!
Another great video to end the week. Keep up the great work Eric!
Hello, I really enjoy your videos! Your methods & sense of humor remind me of my mechanic mentor, Wally, who taught me pretty much everything I know about engines, cars, boat motors, etc. years ago when I was still a young person & before I chose to go into construction. He (like you do)always did a very methodical teardown and thorough inspection. I told my wife that you're a mechanical forensic pathologist. Btw, I'm into collecting & restoring old Mustangs & and whatever else my wife allows me to buy, (she's great!) Anyway, keep up the great work! Thank you!
sir we found the other half of your engine it's in your oil filter sir🤣
Tyler Hoovie Hoover put a nitrous booster on his Pris, took it to the track, started driving, initiated nitrous and 2 seconds later a loud grinding noise and that Pris engine was toast !
8:05 My 1993 Camry V6 has an EGR cooler underneath the intake manifold. I was very surprised to find that on such an old engine.
Eric,
Another great video - thank you!
On all your videos now I click the like button before I even watch as I know Im going to be watching a great video. Dont stop doing what you do.
Much respect.
Paul (in MA)
well a guy at work his daughter got an oil change they didn't tighten her oil filter on and her engine gave up the ghost after two days from peeing it's oil out all over the street when the filter came off simply put she got a newer younger engine mileage wise due to that issue
I had a coworker rebuild one of these (headgasket replacement) in a Prius. Got it all put back together correctly. Went on a test drive to verify everything aaaannnndddd #2 rod left the chat. He drove it back in the EV mode.
That sucks .
Taught me a bunch about my wife’s Prius and my first gen Sequoia…cheers mate! Just subscribed!
A fork lift to check the oil. Love it!
Epic dip stick battle!
It's in the Toyota manual.... 😁
Most engines in my family outlast the frame because of Michigan winters and salt. We can make them last about 20 years minimum. I know a 1993 Saturn SW2 could of last a few more years if it didn’t crash. Not our fault and it was cheaper to buy a new car than repair it.
What kind of oil did you use and what was the interval?
The bane of the salt belt. You csn expect 10-12 years before you start seeing serious corrosion if you arent dilligent about woolwax / fluid film / or some treatment.
Wife's 1998 1.8 litre RAV4 put two rods through the side of the block at 50mph in third gear passing a truck. And it had *plenty* of oil and water (which ended up all over the inside of the engine bay and probably the windscreen of the poor guy who was following us past). It actually drove itself up onto the rescue trailer on the two remaining cylinders.
I could never find out why it blew, I did an autopsy and all bearings were perfect, no scuffing or scoring.
I learn every day something more from your channel. Never knew you have to check your Prius engine oil with a forklift
As always another great tear down, Thanks Eric,
Love your videos! For future reference, channel lock pliers are directional and you were using them backwards on the oil filter housing.
I saw that too and it’s not the first time I’ve seen him do it. No wonder he couldn’t break it loose.
lol “it’s not a rotary, it’s not a Subaru if it’s not those two things they generally seem to last” so true!!
I'm pretty amazed at the technology in even a "mundane" or "boring" Prius engine. I remember reading my dad's old Hot Rod magazines from the 1960s and 1970s, and how high tech roller rockers were, and those engines were usually done around 100k miles. Now 230k is a premature death, caused almost certainly by infrequent oil changes. Perhaps oil changes might even have prevented the sticking rings that likely caused the higher oil consumption. Such well made engines.
Great work Eric! Love your videos! Still hoping you can tear down a 1.8 out of a 2016 Chevy Sonic, and a 2.4 SRT4 engine out of a 2003 PT Cruiser GT that has the aluminum intake setup on it. As usual another great video!
My 2004 Dodge Intrepid 3.5 never gave any warning signs before it started Knocking. Drove it 30 miles to my dads place and parked it on the grass and held it wide open until #2 rod went through the block. Surprisingly it still had oil pressure after deleting that rod.
😂 sometimes you just have to show them who's boss.
@@Me-zo8yc yeah. What else do I do with it. Not like can do much short of putting in a different engine. It wasn’t worth rebuilding so might as well have a little fun with it
Thanks for the 2ZR tear down!! I didn’t know a forklift was required to check the oil. I’ve been doing it wrong.
Awesome and informative as always Eric. Thanks to for the tip on how to remove a stubborn dipstick! 😂👍
I know someone who needed an engine on a relatively new Prius because they took it into the Toyota dealer for an oil change and they went to change it while the car was still "On". The engine decided to fire up on its own with no oil in it while in the air, and by the time they got to shut it off it was too late.
Ouch. I hope the dealer paid for that one.
I would assume the hood was open? If so, crazy an engine would fire like that with the hood open.
@@mph5896 sometimes I leave the care thinking it was off but it's not ofc it warns you with a beep sound if you leave without the key but if the key is inside you don't realise sometimes if the engine is off because it's using the hybrid battery so you hear nothing and then will turn engine on automatically to charge, it's not easy to see sometimes because when it's off and leave the screen is still showing stuff.
@mph5896 as far as I'm aware, the first-gen Chevy Volt was the first hybrid vehicle to force the engine to run when the hood is opened to avoid such an issue. The Prius doesn't.
@@mph5896 Aye. The Prius doesn't give a flip whether or not the hood's open as for whether the engine runs or not. The 2nd gen at least (source: own one) doesn't have any kind of hood switch to tell the computers whether the hood is open or not.
This car was one of the first commercially successful hybrids, and they still went by some more conventional car design paradigms. Such as not tracking whether the hood's open or not.
And as Patrick noted, the car's ghostly silent if powered up in battery mode. Even if the A/C's running, a tech might not hear it in a loud automotive shop until it's too late and the car says "Oops, time to recharge".
Some rods get bent that way, but it's okay, they still work normally. And it's kind of unique!
You have taught me a valuable lesson with your request to keep checking the engine oil and sticking to the change intervals. I think here in the UK we don't generally do as many miles as American cars do (it would be very boring driving round our little island just to get over 250k on the odometer!). Strange to say, but until recently I had bikes and even though I only used them in the summer, I changed the oil every other year, come what may. Why not the cars you ask? Lord above knows, but I promise to do better.
Keep up the very entertaining show and my best regards to Blue!
Best dipstick tube fight I've ever seen, right down to it giving up when you took the chain off and the subsequent roar of triumph.
This engine has its own definition of the Atkinson cycle.
I am impressed that this engine is actually all metal! Cam cover, oil pan... So many modern engines seem to be putting plastic in strange places.
Yes, the lack of a plastic valve cover was disturbing. Apparently they didn't take the challenge from Ford of who can make the cheapest (in both senses of the word) 4 cylinder car engine.
bought my 2012 CT200h. same engine. had 221,XXX miles. got it from a personal friend. had a blown head gasket and a bad CVT since the fluid was never changed on it. Got it cheap 6 years ago and put a complete JDM engine and transmission in it that had never been separated. I've had ZERO issues and no oil consumption issues in 62,000 miles on used engine. I pulled the head from my old engine, sent it to the machine shop, surfaced, put a head gasket on it and sold the engine on Craigslist for $950. it still runs too. They blow head gaskets due to the extreme temperature of it constantly shutting off and never really staying at operating temperature. Piston rings are low tension due to it being an economy car. it is what it is.
I'm over here wondering how the CVT went bad when it's just a single planetary gear set lol
I never laughed so hard when that lower pan came off, revealing that con-rod WRAPPED around the crankshaft!! 😂🤣😂 That image is forever etched in my brain! That was GREAT!! 😁 Compound bend, indeed!! 😀
Would be awesome to see the PCV plate removed from the block and see what's underneath. It's always interesting to see how different manufacturers approach crankcase ventilation differently.
Head gasket failure and oil consumption. The hole in the block is usually from a head gasket failure. The cylinder fills with coolant, then MG1 starts the engine and it's much stronger than a normal starter motor.
the complexity of that front cover is amazing!
A friend is a Toyota master tech. He says he gets a lot of Priusesssss in where the owner has ignored the red triangle of death and now the engine is a glitter factory. More than once he's seen where there's some dash trinket blocking the warning lamp completely.
I worked at a Japanese specialty shop for about 5 years. The shop had been open since the 80s and only ever worked on Japanese vehicles (just Hondas and Toyotas at first, then Subarus and Nissans later). The original owner still owned the place and had 40+ years of experience with Japanese vehicles. For all hybrids, he recommended 7500 mile oil change intervals…except for 2010+ Prii. I asked him why, and he said “our customers don’t know how to open the hood and those Prii will *not* last 7500 miles on an oil change.” Ok then lol
Change your oil at 3000 miles or one year and you will NEVER have a problem-
Great post!
Yes, 3K - 4K oil and filter changes. Oil is still cheaper than metal.
I change the oil in my Prius once every year (10,000 miles) - Toyota Dealer UK. I top up if required - never during city driving but only after long distance trips across country at sustained 70+ mph. I normally cruise at city speed limits using cruise control where ever possible. Bought the 2008 Prius at 54k miles. Has now reached 150k miles (UK) - no problems at all. I use high quality oil, not cheap stuff. Economy reading is presently 66.0 mpg with 4 bars of fuel to go and 420 miles out of the tankful so far. My best record was 69.4 mpg @ 653 miles from my 45 litre tank of fuel - during a blistering heatwave last year.
the service regiment for my 2021 hybrid 1.8l corolla is once a year or every 1500km (9320miles), what ever comes first. I wonder why its different depending on which country you are in.
@@albinfiskare Different oils, different climate, different driving conditions?
2014 had redesigned piston rings and the 2015 added redesigned pistons. Both of those improvement pretty much solved the oil consumption on those 2 models. All of the 3rd gen Prius had problems with the EGR cooler clogging up and causing head gasket issues.
I've never understood how a clogged EGR can affect a head gasket, how are they connected? Not saying it's impossible, just that I've never run across an explanation for how one causes the other. Can you offer any insight?
@@myself248 Part of the exhaust gases flow from the exhaust manifold through the EGR system back into the intake to be put back into the air flow (you're basically re-burning those gases for emissions/efficiency). The EGR cooler reduces exhaust gas temperature as it passes through, leaving behind carbon deposits that build up over time. Eventually, the EGR cooler, EGR valve and piping get so clogged up with deposits that it increases exhaust back pressure, basically putting the engine at greater risk of popping its head gasket.
I'm sure someone over at Priuschat has a far better explanation of what goes on and how a clogged EGR system takes out these Gen 3 Prius engines. I had one @ 180k where the previous owner never touched the EGR. Cleaning all of that crap out was........"fun."
Not sure why but watching you fight the dipstick is always fun. Thanks mate!
I've got a Prius (47k miles only, with oil in it), thanks for the great, instructive teardown, love the humour.
This video made me go check my oil. Looks great, smells good, only has 4k ish miles on it (well within mileage for my car's oil change intervals)
Same. These videos make me paranoid about my engine oil.
5k is the longest I’ll ever go on oil change intervals. Seen far too many engine/timing chain failures at the higher intervals that even manufacturers tend to recommend.
Watching how all a bunch of motors fail on this channel is most of the reason why I am always checking fluids on our 3 cars. Just got a check engine light on our 2009 Honda Fit the other day (don't drive it so much these days) with 150k miles. Borrowed neighbor's OBD scanner to see what's going on, hopefully it's something silly like a sensor that I can order and change real quick. Seems to run fine though but I'd like to catch whatever it is before it potentially becomes a lost cause. I wonder how many miles we'll end up getting out of her after all is said and done. I was hoping to teach our oldest daughter how to drive a stick in it, after letting her get the feel of gas/brake/steering in the automatic Pontiac. Fingers crossed!
Just right amount of knowledge, humor and sarcasm. Keep up the good work!
Well done, Informative and detailed. Thanks for taking the time to share your knowledge.
Thanks for the Prius engine. I have a 2010 with 250k, still running great. Did have to do a head gasket at about 230k though. And I check the oil weekly, since it does drink quite a bit of it.
Was it the EGR cooler leak that inspired the lack of coolant which caused HG problem?
I guess its common to have a Prius "drink oil"?
@@geraldf.1222 Yeah, unfortunately. I have to add a quart about every 800-1000 miles. I've had to do this ever since about 75k miles. I didn't need to before. But one day I went in for an oil change. And my mechanic showed me there wasn't any on the stick. Fortunately it didn't get TOO low. And as shown in the video, you 'should' get warnings if it does. It's just the nature of the engine design, and Toyota considers oil consumption to be 'normal'. And the fact that you use 0W-20 oil, which slides past those low friction rings like water. But, oil is cheap in the big picture. And all the other advantages of the car makes it worth it. I actually use mine as my 'work truck'. And regularly haul 8' dimensional lumber and 10' pipe and conduit in it. People look at me pretty funny when I push my cart of lumber to a Prius. Until they see it all go inside, and the hatch close that is!
@@centauri61032
My 2001 Mitsubishi Galant with the 2.4GDI engine (JDM import) also with low tension rings consumed 1 litre of oil per 100 litres of petrol...so basically a lean running 2 stroke.
Every 5000km it would consume the equivalent of the contents of it's sump in oil.
I still used to change the filter and oil at this time...
I used diesel engine oil, a 10w/40 with extra ZDDP, semi synthetic which seemed to reduce the oil consumption.
I had no check engine light, no catalytic converter problems but it chewed through sparkplugs every 8000km...and if you left it to 10k the sparkplugs would load up with carbon and cause the COP extension to be burned through by the shorting spark or the coils themselves to be fritzed.
@@centauri61032dude that's absolutely insane!!! 😢 my 2013 fusion hybrid has almost 240k miles and I do oil changes every 10k miles in hot Texas, it's used for Uber, and doesn't burn a drop.
