My 2010 prius had engine knocking noise during cold start. Headgasket replacement needed about 800$. Then i totaled it. My 2011 prius was burning oil every 2k miles no oil on the stick . Had to replaced whole engine with 50 k miles engine . 2800$ with labor. Now my prius went over 200k miles on that engine . My car is 393k miles now. Still going strong
Must have gotten a good JDM engine. Many don't realize the gen3 engine was sold in the Asian and European Prius v's until 2022. So it is possible to get one used in Japan that might be from a 2019-22 car.
Toyota had several revision on this engine. The head gasket is revised in 2013, piston and piston rings in 2015. So, only buy 2015 or newer with this engine. REgardless it is Prius, PriusV, Corolla hybrid, or Coroll Station wagon
Thanks Peter for the video! This is a perfect example of owner abuse! Not sure how this car made to 270,000 miles? No oil, gross interior and a botched attempt at fixing the problem in the first place. This car needs to see the crusher! IMO! Who would sink 5000-8000 dollars to repair it? Not me! P.S. Hope you had a great Christmas and Happy New Year to you and yours!
My 2010 lasted 240k before the head gasket failure, I over serviced the car since new with 5k oil changes but this is a design defect. Totaled the car….
99.9% of all Prius problems are owner negligence. Priuses attract people who do not maintain their cars, for example, one of a leading categories of Prius owners are school teachers. School teachers tend to hoard, this is a psychological fact. Look in the back of a school teacher's Prius and you will see a poopload of crap. The only real problems with that generation of Prius is the head gasket and the EGR valve. The engine heats and cools at a much higher rate than a typical engine because it's not always running. Therefore the head gasket is exposed to more expansion and contraction and fails. One way to delay that failure is to change the coolant at 5 years or 50,000 miles before the acidics start showing up. The EGR valve can easily be managed. If the owner just takes care of the oil changes, uses top tier fuels, keeps the air filters clean and the coolants changed, along with changing the transmission fluid which is a simple drain and fill and something like 3 and 1/2 quarts of OEM world standard fluid, that car will last for 40 years.
Ooh! Some brand new lexus!! I wonder about that in the back.. it wpuld be grand if thw automaker loaned pete a new model nx to play woth for a little while.
Viewers in Cali anywhere near this man’s shop need to get the word out so people can get their vehicle in to him before this happens! Many people treat their cars like an appliance and need a honest place to guide them to getting the most out of these vehicles!
Once it’s damaged not much. Change oil consistently every 5K miles before it gets to this point. I have 2010 Prius with 260K and runs strong. I change the oil myself every 4K.
It is very important to keep EGR-cooler, EGR-valve and intakemanifold clean. Change motoroil and filter every 10k km's (6500 - 7000 miles). Replace the electric waterpump previously before it fails. Do only pedal to the metal when the engine is hot. Don't drive like a maniac.
Not much. Primarily because of low tension rings but the gen4 1.8L was redesigned and became reliable if not overheated and run 5 more miles. Gen4 completely redesigned the cylinder cooling, added an insulator plate to even cylinder temps, resolved oil burning, routed egr intake from before the cats to after and more.
Petr, I haven't been getting your videos after that one video you made about taking a break 😢. I have so much to catch up on. Idk why RUclips hasn't been suggesting your videos. Though it did suggest this one
No one can answer this question. Why does my car start at 2000 RPM on warm days and around 1500 RPM on cold days around freezing or below? I've always thought it was the other way around. Any help would be appreciated. 2003 Toyota Camry XLE 3.0 V6 with 136,000 miles on it. Cleaned throttle body, MAF sensor as preventative maintenance. After cleaning I've had a high RPM idle at start up and it started 5 months ago after the cleaning. So about a week ago I decided to replace the throttle body by a certified mechanic that mainly deals with Toyota. So now I still have the 2000 RPM at start up when it's above freezing out but when it's cold below freezing my car starts at around 1500 rpm. It's always been my understanding that during freezing temperatures your RPM at a cold start should be somewhat higher than when it's warm out
Have you disconnected the battery to reset the idle stored? And like the other person said here list all the other engine repairs or modules touched. Location and other pertinent details because the car senses all that with regards to air
@LAactor I pretty much told everything. And yeah I unhooked the battery and ran a jump wire from neg to positive and left it that way for about 4 hours but it didn't do shit. I had no issues with the car just decided to do some preventative maintenance. I recently had a shop replace the throttle body and was told they did the relearn procedure. But it's still doing the same shit. The owner of the shop said bring it back and he would personally reprogram it. I have no check engine light and there's no vacuum leaks. So I don't know what else I can say
When the coolant is below a certain temperature, the ECU detects this and limits the engine's RPM to prevent potential damage. Revving an engine when it hasn't reached the proper operating temperature can lead to harm
You could check the Idle Air Control (IAC) valve or Engine Coolant Temperature (ECT) sensor to see if its sending the correct voltage to the ECU or has the proper resistance. I believe Petr did a video with a V6 Tacoma about it. That could be affecting your idle.
Some people think you can drive a Toyota forever and do no maintenance whatsoever. While a Toyota will last longer than other manufacturers without maintenance, they surely won’t last forever! No excuse to not have any oil in the car.
Will you bill the customer for a diagnostic if they take it somewhere else ? Are you looking for a Prius for yourself ? Do you still have the Tundra ? Don’t those Priuses generally last a lot longer than that one ?
If they keep driving it with a leaking headgasket then sooner or later they will get a haydraulic lock up and when that happens the electric motor is strong enough to bend conrods and write off the engine completly. Top Tip - if it absolutly must be driven with a blown headgasket, remove the radiator cap to depresurise the system. That puts less water in the cylinders
For the gen 3 Prius Toyota completely omitted coolant service from the Scheduled Maintenance log book that the dealers handed new vehicle buyers. The log book goes out to 120K miles. Coupled with Toyota naming their new coolant “Super Long Life”, I suspect loads of new owners never had coolant service performed. With age the coolant became acidic and began to attack the soft black material outlining the galley passages on both sides of the MLS head gasket. Just my hypothesis.
What's with these Toyota head gaskets? Everybody says they're the best. Are they having their Subaru moment ? It's not just the Prius. It's the V-8s too. It does seem a bit odd that people switched to those felpro gaskets. On the one hand I understand why they do it. Because if the Toyota gasket fails, why use OEM? But what is the issue here? Was it assembly? Was it a design issue? Is it just a feature of this engine?
The failure rate is pretty unfortunate on these. Even when in decent condition it's not worth replacing the head gasket. A low mileage used engine or JARKO would a better option if the customer wanted to keep it. It's not worth the liability to the shop or tech to just replace the head gasket and then be married to it from now on. I've had customers that got angry with us because we wouldn't do just the head gasket. Haul it outta here. Not worth the liability.
Maintenance only costs more if you dont take care of your car and that isnt exclusive to Hybrids. Head gasket jobs are expensive regardless of the type of car. Every single thing about this Prius tells you its owner did not car about doing basic maintenance.
Enjoyed your video. Great job troubleshooting the engine.
That poor car - rode hard and put away wet. Thanks for bringing us into your garage once again Peter.
I like the way Peter does not hold back bashing customers vehicles when they are not taken care of :)
He needs to do his damn job and keep quiet. And people wonder why mechanics are dying out..
@@Clooger- Hmmm...the last time I checked, it is his own channel and he can run it the way he wants too.

Thanks for the great informational video. You really know those cars well.
Great video, thanks for creating and sharing.

Same for Prius C?
Prius c is a different engine without its big brother's (oil) drinking problems.
Those damn Prius V owners know this and if they've got a 2016, they're wanting an enormous amount of money, even after the pandemic fade.
I live in rust belt and that Prius looks pristine.

We only see what the most recent owner has done. Perhaps it was newly acquired and had been taken care of better before
The funny part is he may have foreshadowing and may end up with it as a content car again 😅
Abused car lasted that long with critters and dirt all over. Its a testament to reliability. My buddy's well maintained Jeep engine died 113k.
mechanic told me jeep stands for just empty every pocket
Thanks Peter
The owner didn’t take care of the car ! Really no oil ?
Or just not keep up to date with the leaks.
@@LAactor My 2008 Toyota Yaris Sedan has over 300,000 KMS and doesn't burn a single bit of oil. Still going strong!
My 2010 lasted 240k before the head gasket failure, I over serviced the car since new with 5k oil changes but this is a design defect. Totaled the car….
Curious… was the EGR system serviced regularly?
Also… coolant change intervals?

just change the head gasket pretty easy to do
Thumbs up sir
Tub o towels ...try wiping that arm rest to see if it cleans up easy...would be a fun video..and maybe get them as a sponsor
Petrr, Love the videos as always. Just one item of feedback: your mic is possibly too far away as it is hard to hear your commentary.
What can i do or not do to avoid head gasket failure? Avoiding pedal to the metal?
Once it’s damaged not much. Change oil consistently every 5K miles before it gets to this point. I have 2010 Prius with 260K and runs strong. I change the oil myself every 4K.

I'm told that head gasket failure can be causes by old coolant - it attacks the gasket when it deteriorates.
Prius was not made for pedal 2 metal furious driving. 5k miles oil changes are easy to remember. Coast until engine warms up. Drive efficiently.

Happy New Year. Good and informative video. Would it be better to replace the engine or change the head gasket? Thanks.

You could add model, year and miles. Then add engine repairs so far. By who?

270k Mi is a spring chicken. its worth it to repair if the owner can do it himself.
This is WHY I'd never buy a used car UNLESS I KNEW the owner.🤔

Most dealers will not simply replace a hg on these. Petr's dealer's stimates were rebuilt heads to rebuilt or new short block engines.
@@rj.parker I've had good experiences with the JARKO remans. They only do Toyota
Yeah, Prius does have head gasket problems.
Want to buy my 200K Prius?
Is it a 2022?
$4-8k for a head gasket job? So much for saving money on gas, the maintenance on these hybrid junks costs more than the gas would.
Maintenance only costs more if you dont take care of your car and that isnt exclusive to Hybrids. Head gasket jobs are expensive regardless of the type of car. Every single thing about this Prius tells you its owner did not car about doing basic maintenance.
@Jumalten001 I'm sure he meant that this is very common on those cars.
papa don't preach.
Put Blue Devil in and keep driving it.
