Toyota 2ZR-XFE 1.8L Engine Teardown Disassembly - due to bad head gasket on a Prius

- čas přidán 21. 06. 2022
- This engine has 185,000 miles on it and came out of a 2013 Toyota Prius. It has a bad head gasket and I will be tearing it down to the bare block and potentially rebuilding with all new gaskets and seals.
See • 3rd Generation Toyota ... on how to remove this engine from a Toyota Prius.
The 2ZR-XFE engine is an Atkinson version of the 2ZR-FE and is found in multiple vehicles including the Toyota Prius, Corolla, and Lexus CT 200h.

Incredible good engine still, no bearing damage and all. It's very important to clean hat EGR-system every 50 - 80k miles, in order to prevent the headgasket from blowing. The reason is that a clogged EGR-system will cause higher temperatures in the engine which makes the headgasket fail, so coolant comes in the combustion chamber and cause hydro-lock. That makes the engine knock, which is very bad. And do an oil- and filterchange every max 6k miles (10.000 km) with the right oil (0W-20). It will keep your engine from burning oil, so the EGR-system will stay cleaner!
This engine is pretty jumpy on the timing cover and needs passion to work with. The head gasket problems are a kind of a mystery because some have problems and some never. The head gasket is actually revised at the end of 2013. The best one is after 2015 model with revised piston and piston rings. It reduces oil consumption that leads to clogged EGR valve. Clogging EGR valve is believed to be the cause of the head gasket failure. People who clean the EGR valve regularly every 75k miles, or engine without oil consumption issue rarely have head gasket problems. Change oil every 5k miles/6 months reduce the oil consumption risk significantly.
@@rondhole and drive it conservatively!
@@rondhole How do you clean the Egr system?
@@garyvincent9663 there are tons of video how to do it. Especially from car care nuts channel. It is very clear how to do it without too much complication. It is doable DIY as long as we are patience.
@@rondhole My family all have Corollas and we just had one blow a head Gasket. I change oil at 3,000Miles But all the cars where bought used and you never know what was done b4
Its insane how clean that motor is. So it looks like they may have did great on changing the oil. Sadly the EGR design is bad on them and after pinging and detonating on the head gasket for 80k miles from the lack of egr condition the head gasket blows on them. And its cylinder by cylinder too as cylinder 1 loses egr first.
I thought they fixed this in the latter years
@@kimlog7476 I think it should be fixed on the 5th gen but 4th gen has the same issue. Just clogs slightly slower. But at a certain point literally all egr or dpf systems clog.
What a great video thank you so much.
Good disassembly video. Looking forward to the rebuild or maybe even spec checks before assembly. I recently pulled the timing cover and internals along with the head assembly off a ~150K 2011 for some practice testing specs and potential saving of the parts to rebuild so for a quicker swap when I do the head gasket on my 2013 with ~285K miles.
Where's the vdo for putting it back together?
still waiting on this next video!
5 months later the disassembled parts are still laying on top of my work bench just like I left them at the end of the video lol. I should probably put them back together.
I currently own a 2010 Toyota prius, I’m going to drive this car to the ground or when the head gasket blows, get a new car, rebuild the prius engine and sell it for about a grand more than what I paid for it (6k, paid 5)
Going to try to rebuild it myself, doesn’t seem to hard
Great video! 💪🔧
I was hoping to see the piston and rings that was the oil burning problem in the past
What oil was used? What was the oil change interval milage?
How much you charge for complete tear down, replacement of head gasket and re assembly the engine. Very good video
If I were to charge, it would be in the $1.5k - $1.8k range. That includes all new gaskets/seals, new rings, and resurfaced head.
Do you think better piston rings would help with the burning oil problem in the future?
I can't say specifically for the prius but on other engines that I have worked on, replacing the rings fixed the oil burning.
Did you happen to make a reassembly video ? What size bearings were needed?
Still have not had time to reassemble. I will most likely reuse the bearings and install new piston rings & gaskets.
Are you reusing your main and rod bearing bolts too?
If that engine made bottom end noise, given its condition and how there's no bearing damage, you absolutely have a slightly bent journal...
Link to the rebuild by any chance or are you still waiting for parts?
Correct, still gathering parts. Video probably won't be up for a couple weeks.
r u in MN?
I would like to see the cylinder wall. Just in case it has oil consumption issue and a worn cylinder wall. Did you regularly clean the EGR valve and intake manifolds every 75k miles? This helps the risk of pinging/detonation and head gasket leak.
No idea on the maintenance history, I was just hired to swap this engine out. However, the cylinder walls were in great condition. I bought the OEM gasket kit and should be putting this engine back together next week.
@@happywrenching Make sure you get the updated newest part number for the head gasket or it will fail again. There is also updated piston and piston rings from 2015 that completely eliminate oil consumption issue. OIl consumption leads to clogged EGR valve, pinging/detonation and eventually leak head gasket.
@@rondhole thanks for the heads up on the parts revisions!
@@happywrenching Some mechanics recommend Felpro head gasket for 2ZR engines because it has thicker lips than the updated Toyota head gasket. Similar situation with the QR25DE Nissan engine. I owned QR25DE with a blown head gasket at 70k miles and 150k miles later has no issue with the Felpro head gasket.
Have you ever put together an engine and then at the end realize you have 1 or 2 parts remaining?
Its always some bolt that I forgot. That's why now I literally check all nuts and bolts three times when putting something together. On rare occasion I'll leave a rag in the intake manifold and have to take everything off to remove it lol.
Toyota ia king
What size is the crankshaft bolt?
This one is 19mm
what are the other 2 markings at 4:34?
spark delay probably
can u fix my prius?
buddy DIY
Wow. No siezed bolts at all lol
It's a Toyota, that's why. And only 10, 12 and 14 mm bolts...
@@joskd8491 Glad I've got a Toyota then. Just had awful experience with a Honda....but that is a motorbike 😆
Buenas noches amigo muy bueno el vídeo me podrías decir como se llama esos conito q van en el culo de la válvula de ese motor
Can't be worse than the Ford Ecoboost 1.0L engine, which is comfortably the worst engine I've ever owned....
