Can Toyota Engines Fail? Blown up Prius Teardown!
HTML-код
- Опубликовано: 26 сен 2024
- This 1.8L 2ZR-FXE engine from a 2010 Toyota Prius failed catastrophically and locked up. This was likely due to a lack of lubrication to a connecting rod bearing, which caused it to seize. The connecting rod wrapped itself around the crankshaft, causing the engine to lock up. As a result, the MG1 inside the transmission could no longer start the engine, until its hybrid battery was depleted.
Other common issues with the 2ZR-FXE are headgasket failures, EGR valves becoming clogged and oil burning due to low tension oil rings. While Toyota's were once known for their reliability, this particular generation (2010-2015) Prius's were one to avoid.
Here's another 2ZR-FXE engine teardown from a Lexus CT200h that suffered a headgasket issue:

I guess he's really expecting us to believe that is HIS toothbrush? After he steals everything else from family members?
I have a growing daughter now, soon it'll be her brush
@@speedkar99 Nice😀
@@speedkar99 the sacrifices you make for your family are inspiring to the rest of us.
Why would you wanna have variable timing on the exhaust valves?
I'd love to see your bolt collection...
Can't wait for the hybrid portion!
The VVT on the intake only is a specific design to run the engine as an Atkinson cycle rather than Otto cycle. The engine has a compression ratio of 13:1, but the intake gets left open for a moment during compression stroke to reduce the pressure. This allows the amount of fuel and air to compress like it was 9:1, but allows the full expansion. Bad for torque, great for efficiency.
You got it...not a very powerful design but the electric motor makes up for it
The heat cycle of hybrid engines which expands and contracts the metals multiple times DOES damage the head gasket more often than normal cars
No this is Just a shit engine from Toyota

Not aimed at being a great powerful long-lasting engine...
it is aimed at being fuel efficient as part of a system...
It's amazing the amount of damage you found in there. I wonder if the engine was already knocking for some time before it went kaboom
It probably was. This car was trashed inside I can only imagine
Good morning. This is going to be a GREAT day with a new video!
Thanks I'm glad you enjoyed it
This is one of the very best car engine of all time and cars.
Most of the failures occur as result of misuse or neglect.
Timing chain tensioner is oil pressure loaded .
Man I have a 2015 and love it but dread the day the head gasket fails. Some people on forum's are convinced that not completely cleaning the EGR system is what leads to failures but I don't think it's the full story. Really looking forward to the transmission tear down as I know they are unique. Rumor has it that you can change the fluid without the worry of it slipping afterwards.
How does a planetary gear set slip?
Bravo! I always enjoy your shows! I hope you never run out of family clothing which can clean spills, nor toothbrushes.
Small point from an old goat: I see younger people refer to an oil passage as a "galley". Actually the term I think is "gallery". Otherwise perfect, you waste no time, and explain all in great detail. You have a gift for that.
Regards.
first thing the apprentice learns is, how to get clothes from your relatives to clean up oil
@@TheModmc Dobby gets the socks
I've never seen such a crusty head gasket before wow.
my condolences to your tooth brush.... but many thanks to you pointing out the innumerable failure points on that engine. Normally a typical Toyot engine usually outlast the body😄
I don’t know if you can get a metal filter cap for the Prius or other 1.8 motor cars. The ones that have an optional metal cap have a bigger oil filter
the secret to avoid headgasketproblems is changing the electric waterpump (only use an Aisin, which is the OEM!) before it fails, and clean the EGR-system every 30-40 k km's. This can be done by yourself if you are a little familiar with engines. And don't drive like a maniac off course
Oh god, the EGR-system. Source of every problem.
We ALWAYS change oil and filter at 6 months, regardless of miles.
So this motor was burning oil and it just ran out, everything else pretty good.
Top info as always and great explanation. Are the Orange lines attached, HV cables?
Yes they are
I'm here for his wife's old toothbrush and brother's old underwear.
She's so big now! where does the time go..
She sure is 😢😢
Amazing to see how fast they grow and develop skills.
Car care nut says not to swap from original to different oil filter housing because there may be small differences in size so it's not compatible (if the oil filter housing is incorrect it may allow oil to bypass the filter which is bad
Yeah you gotta make sure it fits, they make aftermarket ones.
Oh, not so bad. The engine is still as good as new! 😉
so what caused the failure ultimately? you say it's lack of lubrication but how did that happen? sorry if I missed that part

The low tension rings cause burning oil faster than many other engines.
You might not realize there's no oil until it's too late like this !
@@JohnSmith-pl2bk thanks
Looks like it ran out oil.
You can't blame toyota if the owner doesn't check oil level in a car over 300 ooo miles
The low tension rings used on the pistons accelerate oil consumption
Great mileage before failing.
304km is 188 US kilometers
@@speedkar99 Thats 188,000. US km
Sounds like the head gasket failed for a while possibly coolant killed this cylinder

Thanks for reiterating
This hybrid transmission has two induction motor generator how it works that you create a rotating magnetic field and the rotor lag behind that called positive slip in generator mode the engine drive the rotor faster than the synchronous speed of the stator which is called negative slip.
Great post!
Prius is impressive!
Your daughter came out looking for her dress.....
@7:35
"Daddy, where is my Minnie Mouse dress?" 🥺
Haha! This is probably what she was asking 😂
Premature failure... at 340k kms :) Not bad.
Stop leak gummed up cylinder 3 somehow? Seems like the only smoking gun.

Can you compare this engine with honda k20 engine, which is better ?! Thank you.
Any car brand engines can fail even so called "KING OF RELIABILITY" Toyota can fail, mainly due to irregular oil and filter changes. I have seen Chrysler, Ford, GM engines last forever with proper maintenance which is oil change/filter every 5000km or 3000 miles...........
Cool story bra
@@mann_idonotreadreplies
Even cooler if you remember to check oil levels every time you fill the fuel tank when your engine has low tension oil rings and is getting old.

What year Prius?

Hello there!👋🏻
Hello there!
👍👍
Finally 😁😁😁
They can fail big time.
Oh no! At 7:55, your cute daughter must have noticed you've used her best dress to wipe up the oil!
I think I need a direct link for that bad boy. Can I see how you tear down that transmission?! 😮🫣🖖
Next vid he promised....
Had a neigbour with that engine,he couldnt be bothered checking the oil for a few years until the engine starting to make funny noises,i check the oil & there wasnt any on the dip stick. Wrecked engind,some people are stupid,lazy.
"Hey Princess, watch out, the King may steal your dress." 😂🤣
I think the bars leak type sealant ruined the engine. Engine was fairly clean & pistons not steamed cleaned.
Maybe burned oil, had to add frequently, so it kept the engine clean. I own a gen 4, so this interested me. Gen 4's have heat exchanger that leaks coolant, hence, overheating & possible head gasket probs because of it. 🙄👍🖖🇺🇸

Do you drown everything in Liquid Wrench a day before disassembly ?
kindly make a video on Suzuki M16A engine
