22R E EGR and Air Injection

Description of how the Toyota 22R-E EGR (Exhaust Gas Recirculation) system and Air Injection System works. I discuss the pros and cons of EGR delete kits.

[@techenstein]

This truck and this engine are FOR SALE! Yep, it's finally time to find this thing a new home. Check out the details here: instagram.com/p/CtRv6-VR0L5/?igshid=MzRlODBiNWFlZA%3D%3D

[@mattrowan2680]

Just the most tremendous presentation of EGR & Air Injection that I've ever seen. Congratulations on taking a somewhat bewildering and complex system and breaking it down to a concise, simple to understand lesson. Bravo!

[@dutly13]

I would say its the best explanation I have seen yet in regards to doing an EGR Delete on a 22re. Much appreciation for the information.

[@sleeks9939]

dutly13 I TOTALLY AGREE.

[@BassSniper209]

Great so through

[@amosharting9521]

This was absolutely the Best explanation of the EGR system for my 1985 Toyota 4 Runner...Nicely done Bill!!! I have had mine plugged off for over 10 years after I saw my intake...that looked like a cave with stalagtites and stalagmites and more crap than I care to discuss...Very, Very precise and concise!!!

[@cosmedic]

Great video, thank you. Im a technician myself and just picked up a 22RE as one of my projects, amazing little motor! Ill just add one thing that is very important that anyone considering an EGR delete should know. The reason for the reduced NO(x) from the recirculated exhaust gases, is two fold..it also serves to reduce combustion temperatures, therefore running temperature. Above about 2000F is when molecules get blasted apart in the combustion chamber to form those harmful NO(x) gases. I would be more wary of too hot conditions in a performance motor though, not a 22RE. Thanks again.

[@healedbypitbulls6995]

Wow!! Finally someone tells me what I needed to know bout an EGR delete!! Thank u so much

[@chancecamp4752]

Thanks for explaining the whole system. By far the best video on KZbin. Straight and to the point. Thanks

[@docstockton5564]

I deleted the egr and air injection on my 1981 22R twenty five years ago. When it was running a little hotter, I put in a 180 thermostat instead of the factory recommended 195, and it runs consistently just below half on the gauge.

[@oscarramos1694]

Great Detailed and not overwhelmed explanation...Thanks Bill

[@rafaelperdomo2182]

I just removed the head for a burnt valve. this is the first time I worked the 22r-e. it so simple. I am so lucky it came to me. it brings back my HS shop class. but I did not have to adjust the dwell angle. thank you, Toyota... and thank you for the lesson on this beauty.

[@randallring4193]

Wow... VERY informative and very well presented! Best explanation I've ever seen on those two systems on a 22RE.

[@LittleRiverKingfiser]

I would also say this is the best explanation of the EGR delete on a 22re! Thank you!

[@ocell]

Thank you so much for this! I'm starting a rebuild and assumed I'd want to remove these systems, but after your perfect explanations I'm planning to keep them. You've made sense of the madness.

[@collinlennon1181]

God I love a clean engine. so good.

[@fluxcapacitor1621]

Makes me sick!

[@scotts8364]

I too live in California and get hit up every two years for smog. Your video help me understand what the egr does and why. Thank you. I think my numbers will be better this coming probing. Keep up the good work!

[@snippits75]

Very good video! Lots of love went into that engine build. Secondary air injection had me stumped the first time I had to tear down my 22RE for head gasket and timing chain kit. I am on the EGR delete side especially if the vehicle is not subject to emission testing. Bitmetal switching valve and EGR modulator both gone. Spaghetti vacuum line mess gone. No more throttle body and intake plenum black goo/crud.

[@JardineiroRaizes]

Fantastic explanation. Thank you for that. Also, what a beautiful 22re!

[@paulcini6084]

finialy someone talking about stuff rhey actually know. well done man! subscribed

Excellent video and information. Best 12 mins spent on youtube.

[@theloop82]

This is the best technical video i have seen on this subject. I have a 81 22R and most of the information here seems to apply as well. Nice work and beautiful engine and garage

[@catherinepoloynis]

Thank you. I never realized how complicated all that equipment is. I live in California, taking my 1990 Toyota pickup in for smog retest, and trying to understand the system. It's very technical and delicately balanced... clearly, one needs much experience to diagnose a failure in that system.

[@rondetorres3842]

Great explanation of the EGR and AI. I have a 2WD pickup 22RE and was curious on the function, how it exactly works, and it's related parts. I also live in CA so all these parts have to stay on. Great post and keep bringing the 22RE info!!!

[@gazoodags2683]

Great video! clear, simple, and easy to understand. Thanks man, I really appreciate it

[@BriansGarage1989]

Thanks so much for the information! Very thorough and concise.

[@jessew7978]

Man! This is by far the best explanation of this whole system I’ve seen! Thanks! And beautiful 22re by the way.

[@richardbarreto6205]

That 22RE engine is beautiful! I have a Toyota Celica GTS Convertible that has a 22RE all original but it does not look like that. I wish... I must say these 22RE Engines are very reliable. Thanks for sharing this video.

[@shamos999]

This video is Gold standard for 22re egr

[@kimokahikolekalihi]

Thanks for explaining those two systems. I thought they were all part of the egr system. In the early 2000s I "deleted" the egr from my truck thinking I was freeing up some hp. Truth was, I didn't understand how it functioned back then. Now I once again have another truck with the same 22re and I'm keeping it all factory. I saw the air injection system mentioned a couple times in my factory service manuals but didn't know what it was referring to til just now your video popped up in my feed. Learned something new today! Thanks

[@deadjoey77]

so you dont think its worth it to do the delete? it seems like colder air/gas would be better because of it?

[@kimokahikolekalihi]

@@deadjoey77 no it's not worth it. It only circulates that hot exhaust gas at cruising with part throttle and no load where it actually helps fuel economy.

[@steve5912]

@@kimokahikolekalihiyou’re an idiot if you think egr is good

[@steve5912]

Good video, you’re in cali but you can still run the egr unplugged and slip a plate in between where it goes in the intake manifold

[@fernandofonseca2586]

Best explanation ever 👍 ,Can you ad a filter to prevent oil coming back to the manifold?

[@markharris9040]

Thanks for explaining so it makes sense to me a non technical guy! You’re infoowas very useful and I’m glad I took the time to hear you out👍.

[@flakdawg]

Awesome vid! Been waiting for the full explanation on the systems. I'm constantly back and forth trying to get answers on line and so far its all as what you've explained. Thanks!

[@goatboatmoat2476]

Super helpful. Have you heard if taking off air injection will overheat/damage the catalytic converter at all, with the less oxygen it’s fed making it harder to burn the hydrocarbons?

[@JasonKrasavage]

It's funny I was thinking that the air injection pipe looked really nice and clean, I wish mine looked like that. Then you proceeded to call it a "nasty rusty looking thing" LOL

[@cartoonist1975]

I swear these at the time were built ahead of it's time ! I have 85 GTS celica im working on !

Wow that motor tho "BEAUTY" thanks for the information great video man.

[@ronplucksstrings7112]

Absolutely great explanations!...thanks for taking the time! Cheers from Connecticut!

[@josephdavis2427]

Variable valve timing eliminated the need for an EGR system with reduced induction, thus reduced combustion pressures at cruising speeds.

Great information, high five 🖐 for actually explaining this , I’m converting a 84 carb to a 92 low impedance injection, should be great... should....

[@lesklower7281]

Firstly l live in Australia and l own a Toyota Hilux with a 22R engine l like it and l am retired and its my hobby ute l work on it and have done a lot of nothing to do with removing the engine or anyyhing major thanks to the 22R /RE engine been so popular in the USA parts availability is excellent any part l have needed l can get from a local spare parts shop and other parts l have had to have my whole exhaust system replaced no problem there to pass the yearly regestration inspection and with that inspection no emission test so l can keep driving it because it has a carburetor and no cat converter the 22RE engine was available in the 1980s Toyota Corona Avante

[@99FXR]

Dude..Im painting my valve cover like that when I rebuild the top end.👍🏻👍🏻

[@josuegonzales3921]

Best explanation I’ve ever seen

[@m3chan1zr]

For 22R engines, what controls the air/smog pump since there’s no computer in those?

[@shushucan6859]

How does it inject dead air to help with the engine pumping? The only time air should be let in is when intake valve is open. What stroke are you talking about when it “injects dead air”?

[@user-vh5yf7ps9l]

can you please show where the fuel pressure regulator vacuum line goes. it's one of the 3 metal lines behind the egr valve.

[@vobra]

Great video. Wonderful information. Thanks!

[@evansanders71]

Would the EGR/Injection delete have any affect on the fuel/air mixture when passing through the O2 Sensor?

[@sterlingmakara]

Thank you for explaining it to me, very helpful. I was thinking of doing an EGR delete because I didn't know what it did and I've seen others remove it. However I will definitely keep it and save some gas lol.

[@Frankiebonez337]

You're a god damn legend for this explanation bro! Thanks for the video. HAvent looked yet but I hope you make some more informative 22RE videos!

[@fluxcapacitor1621]

Packed full of valuable info. You should make more videos like this then implement ads to monetize them. Explain all of the EFI elements in the same way.

[@vjkumar831]

The best. Thanks for sharing. Please post more videos of anything related to 22R(E).

[@andrewhardcastle7982]

Thanks a lot just tuning up,here inCA smog test soon

[@alvaroeloredo]

Such an informative video. Thank you.

[@artnoll]

Great video mate! Would not deleting the air injection without deleting the cat clog up the convertor?

[@j45acp69]

the statement that you will have worse gas mileage if you delete your egr contradictory to what I have found. I actually got the same mileage when I removed mine, however when I tore my motor down to rebuild (about 240,000 miles later) I had no more carbon build up in the plenum. I recommend removing the egr if your laws allow it.

[@andrewhardcastle7982]

Excellent , very informative and educational.

[@markreynolds3850]

Thanks for sharing this video, interesting information and informative.

[@camposvazquez]

Thank you for this insightful video... Are you available for consultation? I am rebuilding the 22re in my 1987 toyota dolphin auto trans motorhome....

[@StanKindly]

So I don't have to remove the whole cooler plate to remove the head? Just remove the air injection pipe clamps right? The rest of the air injector piping comes off with the manifolds I suppose..

[@techenstein]

Correct. The cooler plate is only attached to the head, so it can stay together.

[@paulgumper]

Excellent explanation and great video. Thanks for providing the information that I needed.

[@MrJmw8201]

Thanks for this video! Lots of useful info. My 22r is currently getting rebuilt on my 82. Considering getting headers like you have on this. Do you think an LCE header is worth the investment? Just want your honest opinion! Thanks

[@techenstein]

Yea the LCE headers are a pretty good bang for the buck. Not too difficult to install and a noticeable HP boost. I had EFI but I am guessing that on a carb motor it would be easier to tune as well.

[@MrJmw8201]

[@1augustub1]

Great explanation of the conditions of operation for these systems, how do you know that’s correct? Toyota FSM?

[@straightshooterz]

Very informative. Good video and what’s a beautiful 22re

[@alfredobrown]

Hi, is it true that some model years of the 22re came without the air injection system?

[@vicleo1980]

Great explanation very well done.. I had to learn quite a bit about the air injection system because I have a 22R motor and it relies more on the air injection system than the 22RE motor does I believe due to the carburetor. I was getting code 25 fuel lean forever and checked everything even changing the O2 sensor didn't do anything. Went days running fine no codes then 3/4 Days Later code 25 shows up again.. anyways I was going to ask you what did you do with the air injection pipe that attaches to the header you said on the video you were going to make one if so please show us what you did. thanks again good stuff!!!

[@flakdawg]

Great vid! I Would like to see how all the vacuum hoses are hooked up to the metal tree in between the head and plenum. Be cool to learn their use as well. Thanks!

[@kpressler3403]

What paint codes were used for the yellow and orange stripes on the valve cover and on the truck itself?

[@NattyCees]

That was awesome 😎 keep up the good work!

[@Dc5Knightv2]

I have an exhaust leak or I think because the part that is leaking is that air injection pipe gasket after the diaphram, I sprayed it with soap and water and it bubbled it sounds like exhaust leak but you said it's air could you possibly help me understand if exhaust gases could leak from that gasket

[@viciousme90]

sweet! do you have a video for the deletion process for us that wanna do it? what vacuum hoses to take off what to keep etc. thanks

[@jarrodrice9090]

Did u ever get this video? I need one too.

[@RustyRaceHorse]

Excellent video. One other reason to delete the air injection... b/c it costs 2k+ to have the dealer fix it when it threw my check engine light! $35 delete kit and its gone.

[@crashmaster100]

Really great explanation! Good looking motor as well.

[@nabsr]

great video. I live in a county in PA that does not require any emission requirements or testing for inspection. If I do remove both EGR and Air intake on my 1993 pickup will the controlling computer care, and give me some kind of engine lights.

[@techenstein]

For EGR delete, you need to simulate the temp sensor that is on the back of the intake plenum where the EGR connected in. A 10K ohm resistor is all you need. It's a two wire sensor so just use the old sensor connector and wire it in, and tuck back into the rest of the wire harness. There is no sensor for air injection delete and if you already deleted your cat convertor, it's not doing anything anyway. You should keep your first O2 sensor in the pipe though. That is the heart of the EFI system and controls your mixture. The second O2 sensor, if you have one, *might* be optional but it's just as easy to leave it on place.

[@snippits75]

My 92 22RE does not have an EGR temp sensor from factory. I think the EGR temp sensor might be a California equipped thing...not exactly sure. No factory knock sensor either. If you remove the EGR, you can either remove the bimetal switching valve, or disconnect the two vacuum lines to the bimetal switching valve on the front of the intake. Then from there you can remove the EGR modulator...the round hockey puck looking thing. Afterwards, viola,. you can remove most all the vacuum spaghetti. Cap off the three vacuum ports on the throttle body too.

[@jimmyhunt9081]

Damn it...that engine is beautiful. I'm trying to finish up my 4runner engine now. Here in California too. I'm gonna have to guess on all the switches and vacume lines though!😅

[@HamsteakStudios]

What @dutly13 said below me, awesome explanation on performing an EGR Delete. Well done sir! Much appreciated!

[@nicksonthermitus]

Merci pour les informations vraiment complètes. Bonne continuation

[@allseeingI5]

I unknowingly deleted the air injection when I put the CA legal trail gear headers on, and I still have passed smog 4 times, idk how

[@techenstein]

They way they test here doesn't really activate the air injection system so it wouldn't effect the tailpipe during the dyno test, but the tech should be looking for it to be present. I would just keep going to the same place and not say anything.

[@tokyg795]

May we get the link for those exact headers please & thank you.
