The newer Camry has better plastics on the handle. The pre-2002 are notorious for becoming brittle. My Prius 2006, Sienna 2004, and Corolla 2016 has no issue on the plastics.

But seriously... any single head engine is going to have a simple setup. _UNLESS_ it uses a pushrod design. That’s part of why GM and Dodge continue to use pushrods in the 21st century. One chain that’s far simpler than this one. Too bad about the roller lifters and cylinder deactivation, though.

Man...the switch from American engines, to Japanese engines is eye opening. A VVT doesnt mess around. VVT is fascinating. I wonder how far we are from individual, independent, valve control? Like the Freevalve. Seems like Toyota already has very tuned control over valve timing. The next step must be the ultimate control over a combustion engine; a computer controlled, independent valve train....Cool
I took a deep dive into those in my Corolla Camry RAV4 mechanical Reviews. They are quite complicated for a conservative company like Toyota. Hopefully they last as long as their predessesor
Good stuff! One thing I liked about the old 3RZ-FE is that it had an easily accessible/replaceable timing chain tensioner (accessed *without* having to remove the timing cover).
I had the trusty 2ZV-FE(2.5L V6 DOHC 160 hp/tq) on my 1990 Lexus ES250. Had 275k miles on original engine and it was still running strong but some kids vandalized my car and it got totaled out :( RIP ES250 5MT.
the 2 middle pistons get hotter than the 2 outer, being as they are central in the stack and don't benefit from having the extra cooling the outer pistons do. extra oil to help cool them down is a no brainer.
This engine must have very reliable seals for the 5 large horizontal sealing surfaces. Most engines have only three: valve cover, cylinder head gasket, and sump. No doubt they use excellent materials. I own a 1982 Honda CBX-1000 6-cylinder motorcycle that doesn't leak. Nice video!

I've got my '99 2E corolla engine tear down last week because of broken conrod bearing. So while the mechanic is tearing it apart i was watching your videos.

@@speedkar99 Thanks man, watched most of your videos, keep'em coming! The new 2.5 Toyota engine is pretty good aside awful noise during acceleration and lack of low end torque and most of hp coming up high rpm.

I currently drive an 07 matrix with the 1ZZ-FE and it's got a cracked manifold seal (according to the local mechanic, not sure if it's true), bad engine mounts, and a few other minor issues but at nearly 200K miles most of these issues I honestly think I can just overlook until the rest of the car falls apart (been this way for a while - car has had a hard life, especially with the previous owners who I know). Im not sure if these new engines will be capable of running into the ground like this. I certainly hope they retain the legendary reliability.
@@scenicdepictionsofchicagolife I hope so. I guess people were hesitant to DOHC and EFI and VRIS etc, new tech is always scary lol. I hope my Corollas M20A-FKS runs for hundreds of KM lol!
Still got my 1991 3S-GTE turbo engine, just finished a rebuild and was very happy to see there was very minimal wear, mine was starting to use oil alot, turned out to be all valve oil seals were cracked and 8 oil return holes on oil control rings on all 4 pistons were full up of waxy stuff, the control rings were also solid and didn't really move, thank god for the oil squirters! ended up stripping down, washing entire engine with chemicals to remove the waxy stuff from holes gallerys etc, new piston ring set, light hone out, new main bearings as 1 had worn slightly through coating, 2 new thrust washers, new big end bearings, I polished the crank and cam bearings, used plastigauge to size replacement bearings, stuck whole lot back together with new seals and gaskets, its literally going back in the MR2 this week, hopefully will last another 30 years, legendary engines, now got a 3S-GE to put in a Caterham so that's up next for clean & rebuild if needed.
I watched this video a few times, and it had major influence on my decision to buy a RAV4, which I just got this past week. Thanks Speedkar99 -- your vids are a public service.
I had a 2016 Camry le with this engine, 70k miles no issues, I currently have a 2013 rav4 limited with this engine and it has 170k miles, burns some oil not much but no other issues except for that, very reliable engine. and the vvt rattle is pretty harsh on cold starts.
We have a 2009 RAV4 with this engine and less than 55,000 miles on it. Actually ours is a RAV2 cause it's not 4WD. I also change the oil every 5,000 miles and I've done three drain and fills for the ATF.
Quite impressed that this 2.5L 4 cylinder in-line engine can pull a heavy Toyota RAV4 and additional towing capacity. Engineering has come a long way. Congrats Toyota.
That balancing system is the most interesting thing. It would be interesting to know how much longevity that gives to the engine, though, quite how one can do that I don’t know.
This same type of motor is in my 2010 Camry. Best car I ever owned. Great job explaining the parts and operation of this engine. 210K miles and still going strong.
I had a 90 toyota pickup with the 22R-E, 2.4L, I put over 400K on it over 19 years, other than basic maintenance, i replaced the alternator twice, 1 starter motor, and the radiator once. Used to pull a 3500lbs travel trailer with it and it was still running fine when I sold it. best vehicle I've ever owned.
@@ianspeckmaier9565 Mine was pretty good, its a small engine to be sure and it doesn't make much torque until you get the RPM's up, I don't remember at what RPM the power kicked it, but without your trailer get it up to about 10 put it in 2nd and hit the gas, I think around 3K you will fell a good increase in power. I used to wind mine up to 6k regularly and in fact you can get it up to 60 MPH in 2nd get. I used to hold 55 in 2nd climbing mountains if 3rd wasn't doing the job. don't hesitate to let the gearing do the work for you. keep in mind my little truck was well maintained, I always changed oil after 3000 miles and if not on the button but within a couple hundred. Plugs, wires, cap and rotor were also maintained. Buy the time I sold mine it was 19 years old and well over 400k on original engine, not going to say it wasn't getting tired, it was. still ran and drove it around town, it was past its prime for towing, if I still needed it to I think a rebuild would have been the best bet, don't know how many miles you got on yours or how well its been taken care of. but those are things to consider. do a compression test, that will tell you if its still up to the task or needs a bit of care first. I've said many times, that little 90 toyota is the best vehicle I ever owned. best of luck to you and your little truck :-)
oh and one more note, back when I was using it for pulling the national speed limit was still 55, to go over 60 had to take it out of 5th and use 4th, to hit 70 needed to use 3rd. Don't think I'd use it to pull anything with a lot of wind resistance today. with speed limits up to 80 in places you need a bigger engine for like a travel trailer, its not the weight its the wind resistance. My trailer was 2 foot wider than my truck, its like pulling a brick wall.
@@kirknelson156 Awesome appreciate you sending all that that's exactly how mine drives too. I just rev it out and when I get halfway up the power band she seems to have a lot more juice.
The record of these is excellent, the record so far with Dynamic Force engines is impressive for how much more is involved in hitting those efficiency targets. I get excellent mileage on mine.
@@speedkar99 I’d say from what I’ve heard so far is they are even more reliable. The electric water pumps are more reliable than the old leaky belt driven one on this engine. The dynamic force engine is durable enough to run on 0w16 oil. Most people will probably be better off switching to 0w20 after the warranty is done.
Great tear-down - thanks! Bonus is that I now see for the first time how those oil filters with reusable housings work. Can you do their 3.5 V6 sometime please! 😎
I had a 2007 Camry. I bought it brand new. I have had over 20 brand new cars of Ford, Chrysler, GM and Kia in 50 years of servicing my own cars. This Toyota was the only car that started using oil at 30,000 miles. About a quart per oil change which was 3500 miles. First heard it was the valve guide seals then it was low tention rings. So much for their reliability!
There are tons of articles on that series engine showing that it's the oil control rings. It was a _design_ issue; Toyota is still one of the most reliable automakers.
Great teardown. The design looks super simple, compared to some of the other engines you've showcased on your channel. My 2AR-FE Camry is still running just fine at 180,000 miles.
We have a 2010 Toyota Avalon that was given to us by my Brother-In-Law. It was his wife's car. We have the oil and filter changed every 3000 miles without fail, we don't floor it, we don't drive it much over 70 MPH, yet at only about 76,000 miles, it has a bad piston pin. So much for Toyotas being so fantastic.
0:01 OMG There has got to be something better to watch 15:02 OMG This was the best thing I have watched in a LONG time! Brilliant delivery, VERY interesting. Thank You!
had a 2010 rav4 4wd 212000 no problems at all! with 2 front accidents! I was HORRIBLE with my oil changes too, stayed nice and strong. just got a new to me 2018 rav4 awd, gonna treat this one better!
Legendary engine. I had an old toyota pickup in high school, well over 350,000 miles...ran perfectly. Out mudding around I was routinely pulling broken full size Fords and Chevys out of the muck.
@@pryme2013 Nice problem to have, although I don't get why this engine needs balance shafts. Literally millions of 4 cylinder engines around that run just fine without them
I have a Toyota Aurion with a 2grfe v6. I've Just hit half a million kilometres and it still runs perfect. I've thrashed this car regularly since owning it!
I think that engine was recalled by Toyota. My friend had a 2007 Scion tC with a 2.5 L (2AZ-FE) and he got a letter from Toyota (he was second owner) and took it in. Toyota changed the oil, put taped locks on drain plug in pan, on dip stick and on oil fill cap. Told him to drive it 1100 miles and then bring it back. They then decided it was using too much oil and they rebuilt the engine. It had 67,000 miles when this was done. It now has around 120,000 miles and does not use any oil. I guess Toyota knew what they were doing. Good luck.....Jim
@@jimpie231 thanks for the advice maybe I’ll use a magnetic drain plug but she’s going to be selling it soon anyways. The consumption slowed down after doing spark plug seals and higher quality oil but once it breaks down the oil is consumed like crazy.
Your ability to break the engine down and explain everything minute detail is very educational. It seems to sum it up to excellent lubrication and heat control. Yes?
The 2011+ Scion tC also uses the 2AR engine, Ive been trying to find a turbo kit with no luck. Sketchy turbo kits for he 2AZ are plentiful on ebay though.
Just a super well done video. There are people who should make TH-cam videos and people who shouldn't. This Guy definitely should. Keep up the good work.
Owned a '89 corolla and '06 Scion tC. Had only a timing belt issue with the corolla because I got the car used at 140K. Had the tC for 10 years, not a single issue. Planning on getting a Corolla Hybrid at the end of the year.
You CAN actually remove the balance shafts, permanently. You need to plug one of the oil passages though. Grab 2 intake cams and the high compression pistons out of the 2ARFXE to get 260BHP! You will, however, need a standalone/piggyback ecu to manage the timing. The cam phazers need slightly stiffer springs to prevent that noise
5:20 those are GDI injectors, they basically inject straight into the pistons rather than go down a small tunnel like other injectors, 3:20 the timing chain guide rails are made of aluminum not plastic or at least feels like that, but they do have plastic blocks on them, meant to last ages. Also @ 6:48 what engine, the 2arfe, for a brief period ran from 2009-2012 ran a power steering pump and newer versions run electric power steering which makes it easier to service items like the pcv valve and serpentine belts, some people tend to refer to that. The timing chain cover was also changed accordingly getting rid of a few 10 mm wholes where the power steering tensioner would go, difference is the part cover is 310 and 320 for the newer model from the sticker on the side of the timing cover,. 7:48 i like how you mention how it functions as an oil return, have seen quite a few people say their oil piston rings are stuck and thats why there is a lot of oil burning in their car when in reality the pcv valve has failed and its burning roughly 1 quart of oil every 300-400 miles. also a quick and easy test and or fix is to get lucas fuel injector cleaners and throw it into half a tank of gas next time you refuel if you see an improvement after that tank of gas is gone in your oil consumption that means oil ring were stuck and u should proceed with a sea foam clease to reduce oil burn (saves consumer money by mitigating the issue to be more manageable). if no improvement than pcv valve. 13:00 on 2arfe 2013 and newer there was a part revision for the intake cam gear which would make the intake cam gear last longer than previous revisions, it was a defective part or claimed to be defective part since it would break around 100k miles, but the engine would keep going on. Its meant to last a lot longer than that around 200k as thats what most engines should last (lifetime of the engine), but it could go on for longer with the gear broken. Deffo one of my favorite motors though especially for a daily. Never have to worry about that car.
Ended being sold but not driven. 😎 Combustion ain’t going anywhere where they are still running. Also electric is just more fragile oh and also did I forget boring. This whole false pretext of not worrying about reliability of an electric vehicle is such a false reality with you folks it’s so fucking funny.
My 1984 M-B diesel 5 cyl has similar timing chain guides. Aluminum with a plastic liner the chain runs against, perhaps nylon. It also has a similar hydraulic tensioner. My 2002 Chrysler 3.8L has a similar oil pump in the timing cover, driven directly by the crankshaft. The oil drip tubes in the valve cover look like a simple solution and perhaps eliminate having to drill numerous oil feeds in the head.
@@speedkar99 idk, but when i saw my friends '11 camry (xv40 model), they still use the 2.4l 2az. When the facelift came to asia market in '12, which is the xv50 model, they finally use the 2.5l 2ar. Is it still good enough to take the xv40? Or just go ahead and choose the xv50?
I dont think anything will beat their '90s stuff for absolutely overbuilt and simple reliability. The VZ, RZ, MZ and S engines will probably never be topped. Masterpieces of cast aluminum and very minimal use of plastics for anything important. Even the factory timing belts were known to last an absurdly long time though its obviously not a good idea to push it. My buddy bought a 25 year old V6 Camry with 200K miles on it and it doesnt look like anything on it has been touched except the brakes, timing belt, plugs and a couple of vacuum lines. It does need new struts though.

I took a deep dive into those in my Corolla Camry RAV4 mechanical Reviews. They are quite complicated for a conservative company like Toyota. Hopefully they last as long as their predessesor
Entropy tends toward simplicity,unless you are a biologist but they dont need physics
@po18guy What's your point? Simpler engines are also far less fuel-efficient and far more polluting. Complexity exists for a good reason.
@@iankemp2627 wrong. we are talking reliability here, not fuel and emissions. complexity sucks.
@po18guy correct.
Good stuff! One thing I liked about the old 3RZ-FE is that it had an easily accessible/replaceable timing chain tensioner (accessed *without* having to remove the timing cover).
I had the trusty 2ZV-FE(2.5L V6 DOHC 160 hp/tq) on my 1990 Lexus ES250. Had 275k miles on original engine and it was still running strong but some kids vandalized my car and it got totaled out :( RIP ES250 5MT.
I think the oil squirters are primarily for cooling where there's no water jacket. That's why the middle cylinders have more than the outer ones.
Open deck design... I'm sure they cool the bottom of the piston but they are also much better than relying on splash lubrication alone
The oil squirters are purely for cooling the underside of the piston crown and skirt.
the 2 middle pistons get hotter than the 2 outer, being as they are central in the stack and don't benefit from having the extra cooling the outer pistons do. extra oil to help cool them down is a no brainer.
Pretty simple answer here-well designed, made from quality materials, and assembled by hand with care and precision.
This engine must have very reliable seals for the 5 large horizontal sealing surfaces.
Most engines have only three: valve cover, cylinder head gasket, and sump.
No doubt they use excellent materials. I own a 1982 Honda CBX-1000 6-cylinder motorcycle that doesn't leak.
Nice video!
You are right. Not a design I'd prefer but hey it works
@@speedkar99 would you prefer to not have the balance shafts and their complexity? Also why no thrust washers?

I've got my '99 2E corolla engine tear down last week because of broken conrod bearing. So while the mechanic is tearing it apart i was watching your videos. Glad he put it back to normal after replacing the bearing and cleaned my engine. Now feels like i have a brand new car. Reborn engine 😂 even though it has more than 200k milage on it.
The current gen A25A-FKS 2.5L engine inherited a lot from this design, including more plastic parts lol
The A25A is another wonder in itself...lots of new tech. See my Corolla / Camry reviews for that.
@@speedkar99 Thanks man, watched most of your videos, keep'em coming! The new 2.5 Toyota engine is pretty good aside awful noise during acceleration and lack of low end torque and most of hp coming up high rpm.
@@speedkar99 the dynamic force motors are insane in what they bring to the table hut the complexity scares me. I currently drive an 07 matrix with the 1ZZ-FE and it's got a cracked manifold seal (according to the local mechanic, not sure if it's true), bad engine mounts, and a few other minor issues but at nearly 200K miles most of these issues I honestly think I can just overlook until the rest of the car falls apart (been this way for a while - car has had a hard life, especially with the previous owners who I know). Im not sure if these new engines will be capable of running into the ground like this. I certainly hope they retain the legendary reliability.
@@scenicdepictionsofchicagolife now that you know why don't you replace the seal yourself?
@@scenicdepictionsofchicagolife I hope so. I guess people were hesitant to DOHC and EFI and VRIS etc, new tech is always scary lol. I hope my Corollas M20A-FKS runs for hundreds of KM lol!
Still got my 1991 3S-GTE turbo engine, just finished a rebuild and was very happy to see there was very minimal wear, mine was starting to use oil alot, turned out to be all valve oil seals were cracked and 8 oil return holes on oil control rings on all 4 pistons were full up of waxy stuff, the control rings were also solid and didn't really move, thank god for the oil squirters! ended up stripping down, washing entire engine with chemicals to remove the waxy stuff from holes gallerys etc, new piston ring set, light hone out, new main bearings as 1 had worn slightly through coating, 2 new thrust washers, new big end bearings, I polished the crank and cam bearings, used plastigauge to size replacement bearings, stuck whole lot back together with new seals and gaskets, its literally going back in the MR2 this week, hopefully will last another 30 years, legendary engines, now got a 3S-GE to put in a Caterham so that's up next for clean & rebuild if needed.
You do such a good job at these videos. These are exactly the details I want to study. Well done on the whole channel.
I love this channel. Together with I Do Cars, it’s my favorite engine channel. No promo, no bullshit, no intro, pure knowledge.
I watched this video a few times, and it had major influence on my decision to buy a RAV4, which I just got this past week. Thanks Speedkar99 -- your vids are a public service.
Great choice bro
I had a 2016 Camry le with this engine, 70k miles no issues, I currently have a 2013 rav4 limited with this engine and it has 170k miles, burns some oil not much but no other issues except for that, very reliable engine. and the vvt rattle is pretty harsh on cold starts.
thank you for the this engine review, I own a rav4 with this engine for 10 years still running strong.
How many miles and any issues?
@@speedkar99 It has 150000 k on it now and the engine and gear box still no issues, I change oil every 5000 k on engine and 20000 k on gear box.
We have a 2009 RAV4 with this engine and less than 55,000 miles on it. Actually ours is a RAV2 cause it's not 4WD. I also change the oil every 5,000 miles and I've done three drain and fills for the ATF.
Wow. This dude is like a mechanical engineer and a mechanic combined. Really great video. Genius level. Damn!
Quite impressed that this 2.5L 4 cylinder in-line engine can pull a heavy Toyota RAV4 and additional towing capacity. Engineering has come a long way. Congrats Toyota.
Yes it's quite powerful if you think back 15-20 years ago what a 2.5 was rated it
I have a 2018 rav ,2.5,very interesting breakdown,love all that tech talk.I like your delivery speed.easy to follow
That balancing system is the most interesting thing. It would be interesting to know how much longevity that gives to the engine, though, quite how one can do that I don’t know.
This same type of motor is in my 2010 Camry. Best car I ever owned. Great job explaining the parts and operation of this engine. 210K miles and still going strong.
I’m new to the 1GR-FE would be super rad to see a tear down. I hope to keep the wife’s 2020, and my 2021 going for a long long time.
I would like to teardown any GR engine.
I have the 2GR in my Lexus GS
That’s a great engine. Been around for a longgg time. You will have many trouble free years with it.
I had a 90 toyota pickup with the 22R-E, 2.4L, I put over 400K on it over 19 years, other than basic maintenance, i replaced the alternator twice, 1 starter motor, and the radiator once. Used to pull a 3500lbs travel trailer with it and it was still running fine when I sold it. best vehicle I've ever owned.
Please tell me, what was your experience towing? I have an 89 with a 22re and it feels absolutely gutless.
@@ianspeckmaier9565 Mine was pretty good, its a small engine to be sure and it doesn't make much torque until you get the RPM's up, I don't remember at what RPM the power kicked it, but without your trailer get it up to about 10 put it in 2nd and hit the gas, I think around 3K you will fell a good increase in power. I used to wind mine up to 6k regularly and in fact you can get it up to 60 MPH in 2nd get. I used to hold 55 in 2nd climbing mountains if 3rd wasn't doing the job. don't hesitate to let the gearing do the work for you. keep in mind my little truck was well maintained, I always changed oil after 3000 miles and if not on the button but within a couple hundred. Plugs, wires, cap and rotor were also maintained. Buy the time I sold mine it was 19 years old and well over 400k on original engine, not going to say it wasn't getting tired, it was. still ran and drove it around town, it was past its prime for towing, if I still needed it to I think a rebuild would have been the best bet, don't know how many miles you got on yours or how well its been taken care of. but those are things to consider. do a compression test, that will tell you if its still up to the task or needs a bit of care first. I've said many times, that little 90 toyota is the best vehicle I ever owned. best of luck to you and your little truck :-)
oh and one more note, back when I was using it for pulling the national speed limit was still 55, to go over 60 had to take it out of 5th and use 4th, to hit 70 needed to use 3rd. Don't think I'd use it to pull anything with a lot of wind resistance today. with speed limits up to 80 in places you need a bigger engine for like a travel trailer, its not the weight its the wind resistance. My trailer was 2 foot wider than my truck, its like pulling a brick wall.
@@kirknelson156 Awesome appreciate you sending all that that's exactly how mine drives too. I just rev it out and when I get halfway up the power band she seems to have a lot more juice.
The record of these is excellent, the record so far with Dynamic Force engines is impressive for how much more is involved in hitting those efficiency targets. I get excellent mileage on mine.
It sure is amazing how complex it is. Waiting on long term reliability data to see how it'll hold up
@@speedkar99 I’d say from what I’ve heard so far is they are even more reliable. The electric water pumps are more reliable than the old leaky belt driven one on this engine. The dynamic force engine is durable enough to run on 0w16 oil. Most people will probably be better off switching to 0w20 after the warranty is done.
I like the way you explain to us, easy, short, no music, no introduction@understood
Thanks
Following you from arab middle east🌹
Thanks from Canada
Short and to the point is how it's gotta be
Great tear-down - thanks! Bonus is that I now see for the first time how those oil filters with reusable housings work. Can you do their 3.5 V6 sometime please! 😎
I had a 2007 Camry. I bought it brand new. I have had over 20 brand new cars of Ford, Chrysler, GM and Kia in 50 years of servicing my own cars. This Toyota was the only car that started using oil at 30,000 miles. About a quart per oil change which was 3500 miles. First heard it was the valve guide seals then it was low tention rings. So much for their reliability!
They're reliable but oil is just part of the running costs on these 😟
There are tons of articles on that series engine showing that it's the oil control rings. It was a _design_ issue; Toyota is still one of the most reliable automakers.
Great teardown. The design looks super simple, compared to some of the other engines you've showcased on your channel. My 2AR-FE Camry is still running just fine at 180,000 miles.
Mine is ready to hit 270k.. Runs like it did in 2010.
We have a 2010 Toyota Avalon that was given to us by my Brother-In-Law. It was his wife's car. We have the oil and filter changed every 3000 miles without fail, we don't floor it, we don't drive it much over 70 MPH, yet at only about 76,000 miles, it has a bad piston pin. So much for Toyotas being so fantastic.
That toothbrush is very reliable too. LOL.
Colgate 👍👌
It’s also made by Toyota!

Great video! Would love to see tear down of the 2AZ-FE engine in the future
That's not a good example of a Toyota motor haha
@@speedkar99 Please do so, Ive been wanting this for so long! I still have my solara since your solara videos
The black sheep of the Toyota engines
Had a scion tc with this engine. Redlined it every gear, all day, everyday. Never an issue and had 130k miles
210k redliner here, still going absolutely no worse for wear! Remarkable motor, going for 500k, because why not
Timing chains also needs to be replaced after certain miles tend to stretch, less frequent than the timing belt driven engines.
Chain is still better
Great video on a great engine! My Rav4 after 8 years drives like new, phenomenal performance with basic maintenance.
Keep it going!
Wow you are very knowledgeable on these Toyota engines....you would make a great teacher!

9:15 I'm sure you know that kind of play is normal in almost all engines.
Exactly, that is why he didn't find any wear on the bearings.
Wow.....I’m impressed! Good job, no baloney! Thank-you very much! Lots of detail! Jim
PS.....have a 2017 Toyota RAV4.
I’m changing my oil tomorrow
The knowledge that this guy spits out is truly incredible!
I like the looks of this engine. Sure a lot more sensible than that BMW inline six we looked at a while ago.
I know right! Not nearly as complicated and still will out last it.
I mean the BMW engine makes significantly more power in all fairness.
If you're rich get BMW, if you want something to get you from point A to B Toyota is a better choice
had a 2010 rav4 4wd 212000 no problems at all! with 2 front accidents! I was HORRIBLE with my oil changes too, stayed nice and strong. just got a new to me 2018 rav4 awd, gonna treat this one better!
Nice. Please take care of it. Should last you a while.
Can you do a video on the Toyota 22R/RE engine? It was a bombproof piece of machinery.
Legendary engine. I had an old toyota pickup in high school, well over 350,000 miles...ran perfectly. Out mudding around I was routinely pulling broken full size Fords and Chevys out of the muck.
@@RealityIsTheNow I own a corona station wagon for 15 years with 22 re injection motor in it, simple and reliable engine.
Dual row timing chain with metal guides in a small four is way overbuilt!
@@pryme2013 Nice problem to have, although I don't get why this engine needs balance shafts. Literally millions of 4 cylinder engines around that run just fine without them
Old but good. Also hard to find now lol
I have a Toyota Aurion with a 2grfe v6. I've Just hit half a million kilometres and it still runs perfect. I've thrashed this car regularly since owning it!
Love these engines my mom has a 2007 with 210k miles it’ll run no matter what but does consume a lot of oil through the oil control rings I believe
That's probably the older 2AZ
In other words, it's a bad engine that is still on the road with +200k miles lol gotta love how tough Toyotas can be.
@@mr.boostang2064 no not really the engine is really well built besides the faulty piston rings
I think that engine was recalled by Toyota. My friend had a 2007 Scion tC with a 2.5 L (2AZ-FE) and he got a letter from Toyota (he was second owner) and took it in. Toyota changed the oil, put taped locks on drain plug in pan, on dip stick and on oil fill cap. Told him to drive it 1100 miles and then bring it back. They then decided it was using too much oil and they rebuilt the engine. It had 67,000 miles when this was done. It now has around 120,000 miles and does not use any oil. I guess Toyota knew what they were doing. Good luck.....Jim
@@jimpie231 thanks for the advice maybe I’ll use a magnetic drain plug but she’s going to be selling it soon anyways. The consumption slowed down after doing spark plug seals and higher quality oil but once it breaks down the oil is consumed like crazy.
Your ability to break the engine down and explain everything minute detail is very educational. It seems to sum it up to excellent lubrication and heat control. Yes?

If someone told me YOU invented engines I'd believe them. Very impressive young man! New subscriber.
The 2011+ Scion tC also uses the 2AR engine, Ive been trying to find a turbo kit with no luck. Sketchy turbo kits for he 2AZ are plentiful on ebay though.
As a Scion tC owner, putting a turbo in it is just laughable to me.
@@Justin-nx3pw Yea, but I figured getting a used kit for ~$2500 and reaching around 300 horsepower wouldnt be a bad upgrade for some fun.
Not sure how I'd feel turboing a tC
Keep it stock, and it’ll be reliable, play with it and you’ll always be working on it. Been there......Jim (I’m 74 years old)

You CAN actually remove the balance shafts, permanently. You need to plug one of the oil passages though.
Grab 2 intake cams and the high compression pistons out of the 2ARFXE to get 260BHP! You will, however, need a standalone/piggyback ecu to manage the timing.
The cam phazers need slightly stiffer springs to prevent that noise
Wow you did all that with just a toothbrush! Great video and thank you for your direct-to-content style!
Don't forget Papadakis's stroker 2AR on the Corolla.

103k? 230k still kicking. motor mounts replaced a few times.
I think when you do tear-downs like this it'd be cool to know how many miles they have on them.
And what oil they had in them and how often it was changed.
I don't have history on most of these engines. I just buy them off people who have swapped/scrapped them and don't know themselves

Thanks for this video. Very educational.
Glad you found it helpful. Please share on your network
5:20 those are GDI injectors, they basically inject straight into the pistons rather than go down a small tunnel like other injectors, 3:20 the timing chain guide rails are made of aluminum not plastic or at least feels like that, but they do have plastic blocks on them, meant to last ages. Also @ 6:48 what engine, the 2arfe, for a brief period ran from 2009-2012 ran a power steering pump and newer versions run electric power steering which makes it easier to service items like the pcv valve and serpentine belts, some people tend to refer to that. The timing chain cover was also changed accordingly getting rid of a few 10 mm wholes where the power steering tensioner would go, difference is the part cover is 310 and 320 for the newer model from the sticker on the side of the timing cover,. 7:48 i like how you mention how it functions as an oil return, have seen quite a few people say their oil piston rings are stuck and thats why there is a lot of oil burning in their car when in reality the pcv valve has failed and its burning roughly 1 quart of oil every 300-400 miles. also a quick and easy test and or fix is to get lucas fuel injector cleaners and throw it into half a tank of gas next time you refuel if you see an improvement after that tank of gas is gone in your oil consumption that means oil ring were stuck and u should proceed with a sea foam clease to reduce oil burn (saves consumer money by mitigating the issue to be more manageable). if no improvement than pcv valve. 13:00 on 2arfe 2013 and newer there was a part revision for the intake cam gear which would make the intake cam gear last longer than previous revisions, it was a defective part or claimed to be defective part since it would break around 100k miles, but the engine would keep going on. Its meant to last a lot longer than that around 200k as thats what most engines should last (lifetime of the engine), but it could go on for longer with the gear broken. Deffo one of my favorite motors though especially for a daily. Never have to worry about that car.
combustion engine is going to be ended in a few decades, we don't have to worry about reliability of engines of normal vehicles no more
Reliability of electronics
Ended being sold but not driven. 😎 Combustion ain’t going anywhere where they are still running. Also electric is just more fragile oh and also did I forget boring. This whole false pretext of not worrying about reliability of an electric vehicle is such a false reality with you folks it’s so fucking funny.
My 1984 M-B diesel 5 cyl has similar timing chain guides. Aluminum with a plastic liner the chain runs against, perhaps nylon. It also has a similar hydraulic tensioner. My 2002 Chrysler 3.8L has a similar oil pump in the timing cover, driven directly by the crankshaft. The oil drip tubes in the valve cover look like a simple solution and perhaps eliminate having to drill numerous oil feeds in the head.
I like these demonstration videos, but do you take these engines apart for any other reason?
Nope. Just for my own learning and yours.
I love the toothbrush as a pointer. Truly conscious of the in the environment as a multiple use tool. Good job man
so, do you still recommend if i buy a '11 camry with 2az-fe engine? What are the things needed to be check before buying this specific type of car?
11 Camry came with 2ar
@@speedkar99 idk, but when i saw my friends '11 camry (xv40 model), they still use the 2.4l 2az. When the facelift came to asia market in '12, which is the xv50 model, they finally use the 2.5l 2ar. Is it still good enough to take the xv40? Or just go ahead and choose the xv50?
I dont think anything will beat their '90s stuff for absolutely overbuilt and simple reliability. The VZ, RZ, MZ and S engines will probably never be topped. Masterpieces of cast aluminum and very minimal use of plastics for anything important. Even the factory timing belts were known to last an absurdly long time though its obviously not a good idea to push it. My buddy bought a 25 year old V6 Camry with 200K miles on it and it doesnt look like anything on it has been touched except the brakes, timing belt, plugs and a couple of vacuum lines. It does need new struts though.
you sir are a tru hero keep up the good job
