Thank you for watching, and good luck with your repair! 👍
Thanks for the great DIY video. I believe I'm experiencing the same problem that is addressed her. I would like to ask if you may have seen oil elsewhere due to Chain-Tensioner leak? I myself had oil all the way up to right side of radiator on the splash guard, on the CV Axle and on serpentine belt. No leaks near filter or pressure sending unit. Nor on the valve cover gasket,etc. I do see oil on the back side near chain-tensioner and below it. Also, how has your chain- tensioner replacement gone? Did the experimental seal replacement seal better? Thank you for your time and I look forward to your reply.
@@UnifiedPeoples So far, so good on my repair, but I really haven't driven too much, so I'll need probably a few months to really determine if the Molykote 55 and alternate/harder o-ring will do anything to prevent the leak. As for the leak - this leak can make a huge mess, to include the big mess you're describing. However, if you're not sure where the leak is originating, drive the car up on some ramps and slide under with some Super Clean (or other cleaner) and a roll of paper towels, and clean up what you see. Try to get it rather clean - it is worth the effort, and I know it is a pain in the neck cleaning under there! Clean up around the tensioner itself, then check back after a few drives to see if you can definitively locate the source. Another spot you can get a messy leak is from are the o-rings on the VVT solenoid and camshaft sensor - check out the video link below to see those items (they are super easy repairs, luckily!). Basically, if you're not sure where the leak is originating, it really is worth the time and effort to clean up the oil leak and try to find the source. I hope that helps : ) Here's the video on the other o-ring oil leak sources: th-cam.com/video/ZiRoBR22d6g/w-d-xo.html
I have been an aerospace educator for over 40 years, I rebuild Porsche 911 engines as a hobby. These are far and above the absolute best automotive repair DIY videos I've ever seen. Teaching/educating is solidly in your DNA! GREAT JOB! Keep it up.
Wow, that's a very kind comment - thank you! And thank you for being an educator for over 40 years and teaching so many people what you've learned - you've made a wonderful contribution to the whole world! There must be aerospace people all over the world who have learned from you - how cool is that?! Thanks for watching : )
This is the best repair video I have ever seen! Great videography (picture in picture), easily understood explanation with documentation, thoroughly detailed, narration was pleasant, the pauses with highlighted annotations, time stamps, listed part numbers & you did not talk down alternative ways shown by others on TH-cam. You put a lot of work into this video! Bravo!!!! I really enjoyed watching it. I didn't skip forward at all while watching this video like I usually do. 😃 I am a subscriber for sure.
Agreed 100%!! Informative, great cam work, and great little tech tips.....d.i.y.'rs don't understand what damage can be done when messing with timing components. Great job explaining how to get it to cyl #1 TDC BEFORE removal and the detailed camera work showing the timing marks on the crank pulley.....are you really a videographer or an auto tech??.....a bit of both huh?😊 Best repair vid I've EVER seen. No bs!!
This video is freaking FANTASTIC!! From the narration, to the camera work, to the pauses w/circles, arrows and text..... pure master class in how-to / tutorial videos! Love it! Also, cool tip for putting the new O-ring on! Toyota and Snap-On probably make a special $300 tool for that - LOL!
I am 17 and I just got done rebuilding my 1zz-fe for my Toyota Celica and I have never seen a better teacher. I recently graduated from online highschool because I couldn't stand any of my teachers. But during this past hour and a half I have never been so intrigued and have never learned so much about a process that I have already done. I absolutely love how you go into grave detail in every single portion of this process and take the time to teach the watcher how it functions and how you can better understand each and every mechanical attribute of this system. Thank you for taking the time to add in every detail and edit these videos we all appreciate it!
Wow, that is outstanding work - congratulations on your 1ZZ-FE rebuild! You should be very proud for having completed such a technical endeavor - well done, very well done! Great job!! I'm so glad that you liked the video, and thank you for watching! : )
The tensioner is a culprit on the 2ZZ GE (Celica) engine and the O-Ring leaking. However, many replace the O-Ring and/or tensioner and it still leaks. Usually the timing cover gasket is the culprit then. The gasket dries out and cracks and leaks oil. However, always make sure some RTV is applied in key areas according to manufacturer tech book and correct torques when refitting timing cover. Otherwise the leak can come back. Brilliant step by step video here. Wish many people took the time like you have to explain clearly.
Yes, unfortunately that is a fairly common problem on the 2ZZ-GE engines as they get older. The 1ZZ-FE has a form-in-place gasket (FIPG, gasket-maker, RTV) for the timing case cover, and it seems to be a bit more durable as timing cover leaks are less common on the 1ZZ-FE. Thanks for watching and for adding your tips! : )
Bravo! I already know how to do this on my Vibe ( same engine) but I learned several things and heck was “infotained” for an hour. I will use this as inspiration for a video in my line of work to teach people who already know how to do something their way ,how to do it the right way going forward. And why it’s important. My multi billion dollar business could learn some best practices from you!
Thank you! That's great that you're making a video to show the proper techniques for your field's applications: I'm a big fan of detailed videos, especially for technical operations because technicians can watch and re-watch a detailed video as a sort of practice for the real work ahead. A good video can give a technician more confidence for executing a new operation, and for common operations, a good video can explain why a certain technique/step is necessary even when it is not apparent why it's necessary, and may even seem like "a waste of time". That's basically why I did this video - I noticed many people wondering online as to why a conservative mechanic might price this job higher and coupled with a valve cover gasket replacement, while many other mechanics don't. Some people mistakenly thought that the first mechanic was just "ripping me off!" because they didn't understand why he'd remove the valve cover when they've seen several videos on TH-cam of regular people doing the tensioner replacement in 15 minutes, without removing the valve cover and "everything was fine". So, I just wanted to explain that while, yes, it is possible to do the job in 15 minutes without removing the valve cover (as shown in many other videos, and as even often done in shops by technicians, including Toyota techs), ultimately the person paying the bills and making the decisions needs to know that executing the repair in that way ("blind") comes with the very low-probability but very high-impact risk of timing chain skip on an interference engine, which typically causes catastrophic engine damage when it occurs. Here is an example, with a picture: www.toyotanation.com/threads/broken-cam-chain.1466994/ An average DIYer might not know that such catastrophic damage is possible from "such a simple DIY on youtube", but a technician or mechanic ought to know. A conservative tech or mechanic is simply not willing to risk chain skip on an interference engine, period, so he will spend the extra time and gasket to "just do it right" and simply remove the valve cover so he can see what he's doing, confirm tensioner release and double-check timing, and therefore eliminate the risk of catastrophic damage. Conservative mechanics also prefer to resolve doubt as much as possible/reasonable rather than to rely strictly on chance, so the visual confirmation resolves the doubt, too. So - anyways - a big thanks to you for making videos for your people, too, so that they can do their operations well and understand why they're doing what they're doing! And thanks for watching : )
I am Iraqi and I do not speak English well, but this video is very good, rather excellent, and even those who are not fluent in English understand it, and I understood 90% of it. Thank you very much and keep broadcasting
Great video. Many thanks. If you continue offering us this kind of video lectures many of us will rather spend our weekends working on our cars. I really appreciate what you are doing. We need more teachers like you, honestly. Regards from Florida.
Thank you for this video! I changed my valve cover gasket today to stop a leak only to realize it was the tensioner o-ring. I ran out for the part, and your video really helped me do the job without damaging my engine. You rock!
Subscriber for LIfe! You are absolutely the BEST teacher on the internet. Thank you so much for all of your hard work and effort. You are much appreciated!
Thank you! I have rebuilt this engine, but didn't record video because there is actually already an excellent bolt-by-bolt by another youtuber here: th-cam.com/video/A595LR4SQpI/w-d-xo.html That video is outstanding: there are a few little differences since he's working on the oldest version of the 1ZZ-FE (for example, you wouldn't hone the cylinders on the later version 1ZZ-FE found in the Matrix), but overall it is a gem video. I hope that helps - thanks for watching! : )
Holy crap! This is the best DIY car repair video I have EVER seen on TH-cam. Thank you SO MUCH for putting the time and effort into making this. The notes and annotations we super helpful. Yeah it's long, but 100 out of 100 times I'd rather be able to fast forward the parts I don't need than have incomplete instructions. Please keep making these, especially for 1ZZ-FE engines!!
Watched your door check video for my '04 Pontiac Vibe a number of years ago, and here I am again! You make absolutely excellent videos - thank you for what you do. Here's to many more miles out of my 1ZZ-FE! :D
I love your attention to detail!! I wish I could find a mechanic like you here in Waco Texas. I am disabled in a wheelchair and I take my Toyota Sienna to the dealership, but I always worry who is working on my van. I enjoy all your videos!!
Thanks! : ) I know what you mean about shops: it's difficult to find a shop to trust, unfortunately. I'm not familiar at all with the Waco market: you might be able to find some suggestions in the Sienna or general Toyota forums about independent shops that people in Waco trust. Hopefully your Sienna doesn't require too much repair - they are reliable vans that last a long time! Thanks for watching! : )
I'm doing DIY repairing my corolla. At first time, it started cleaning manifolder intake, and then I am getting disassemble the engine, and need some information how to set up crank and camshaft, your video clearly shows how to set up crank and camshaft, I am searching another video how to remove engine block...LOL. Thank you for your video. 😀
This below is one of the best videos I've seen on the 1ZZ-FE - it doesn't show the block removal, but it shows a lot of other great info: th-cam.com/video/A595LR4SQpI/w-d-xo.html There are some differences between the early 1ZZ-FE (like the one shown in that video) and the newer 1ZZ-FE (for example - you don't the cylinders on the newer engines), but overall that video is a real gem, if you haven't seen it! Good luck - sounds like a fun project! : ) Thanks for watching
Thank gou so much for this outstanding video. Everything about it is top level. Production values are above and beyond. Referncing, specifications, explanations, options, tips and tricks, every checkbox ticked and exceeded. All delivered in a clear, concise one hundred per cent understandable manner. Thank you, thank you, and thanks again. Very best wishes 🙏🏼😊
The way you do your repairs with explanations is good. It help those of us who want to learn automobile engineering so easy to to understand. So now I would want to you send me some of your repairs videos. So captivating.
Best video so far I have seen about Toyota Celica tensioner reinstallation/reactivation, detailed and explained clearly why Toyota procedure calls for counter-clockwise procedure! Well done!
Thank you! This video did take a lot of time, LOL - my videos tend to take me way longer than I ever expect them too : ) Thanks for your comment, and thanks for watching!
it was one of the best videos i’ve ever seen in you tube automotive industry! the only comment that i would add to this video ! toyota updated this o ring and the latest version is a little bit different and they resolve this problem ❤❤❤
Wow, that is outstanding info - thank you very much for adding that info! I will check that out: do you happen to know if the updated o-ring has the same Toyota part number, or another part number? Thank you for watching, and Happy New Year! : )
Wow, I did this procedure without watching this first. Did the counter clockwise clockwise move listening for the soind. But seeing this, just made me realise that i got lucky, results could have been disastrous. Thanks for explaining this procedure in detail.
Great attitude & video! My 03 has 260K miles and I'll soon be opening it up to check valve clearances. Six exhaust and two intake valves needed adjustment at 170K. Those last two exhaust valves are a concern since you can burn a valve if you run them too tight for long and they usually get tighter as the seats wear. Glad I got lucky when I replaced the tensioner over a decade ago.
This is the work I need in my 2006 Corolla with 285K km…the engine is soaked in oil from behind by where the timing chain tensioner and wet oil on ignition coil so valve cover gasket needs to be replace for sure, I’ve notice when I replaced the spark plugs….after watching your video I’m less intimidated to do it myself….thanks for your video.
Thanks for making this video !!! Chain skip is a really big risk for people who have older Corollas with lots of miles on them since the timing chain will be more stretched and have a much greater risk of having the chain skip a tooth. I have a slight leak on my tensioner and instead of changing the O-ring I simply added a 236 ml bottle of 'AT-205 RE-SEAL' to the engine oil when I changed my engine oil and that seems to have fixed the oil-leak problem for me.
Yes - some people do use RTV: I haven't heard of people using it on the o-ring itself, but on the flange I have certainly seen that. Personally I don't use RTV because it just tends to make a mess for the next person. Here's the perspective from a Toyota tech on the matter: www.toyotanation.com/threads/diy-2003-2008-corolla-matrix-pontiac-vibe-1zzfe-timing-chain-tensioner-replacement.1255385/ I hope that helps - thanks for watching : )
I am amazed, proffesional work and videoedit. I just did the same on my mini 3ZZFE engine and it was pleasure to follow your instructions :) Greetings from Prague.
What a well documentated and beautifully executed tutorial. Love your video style and your calm soothing voice narration. Subscription worthy 100%. Very surprised it leaked again....what is going on with Toyota quality? At least that tensioner doesn't require a grenade pin and doesn't require Herculean pressure to push it back in like some Subaru ones.
Haha, yes this tensioner is much easier to work with, and it is nice that it is accessible without removing the chain cover. As far as the o-ring leak - I'm not sure what's going on, but unfortunately it has become a common issue. From what I understand, the factory installed o-rings (ie, installed in '03 - '08) lasted quite a long time and typically didn't start leaking until 10 years or more later. But at some point, the quality/supplier must have changed, because these o-ring leaks too often. I hope my experiment works! : ) Thanks for your comment and thanks for watching!
Thanks! I myself don't teach, but I have taken lots of courses over the years on different subjects, and I highly appreciate a good teacher! : ) Thanks for watching!
Wow I'm so impressed this is the most detailed video I've ever seen in my life that's absolutely freaking amazing thank you for producing this amazing video I will share it with everybody I know who has this engine are you a master mechanic you should teach shop class definitely
Such a GREAT VIDEO. MY 2012 COROLLA AT 176K MILES HAS THIS ISSUE. I PERSONALLY GAVE MY CAR TO MY MECHANIC AND GAVE HIM YOUR VIDEO AND SO I AM SURE HE WILL CHARGE ME FOR THE valve head gasket replacement I should have got that, bummer. But I did buy a new timing chain tensioner and gasket from Toyota OEM PARTS. My wife and i just visted Colorado over a month ago. We had a blast. Beautiful State
It's been a year since you posted this video but thank you very, very much for doing it. I followed the video's fantastic directions and installed a new chain tensioner last weekend with no drama. I opted to use a screwdriver to release the chain tensioner, which was very easy and guaranteed no chain skip. Please let us know if the O-ring you installed with the moly grease is better than a Toyota O-ring. It's relatively still new but, if possible, please post any videos on how to do maintenance on a Toyota's hybrid system and the A25A-FXS engine.
Excellent work, this level of detail gives DIY’ers the confidence to get these jobs done right. Would you recommend cleaning out the valve cover gasket with brake cleaner or degreaser before reinstalling?
Thanks! If you mean cleaning out the channel where the valve cover gasket fits with brake cleaner, then yes, you can do that. If you don't have brake cleaner you can use degreaser, or even just a paper towel to remove the old oil before installing the new gasket - just something to get it clean so you don't mistake old oil as a new leak after the repair. If you mean that you're re-using the valve cover gasket (like I do in the video) and you're asking if you should clean the gasket itself - then, no, I wouldn't use brake cleaner or degreaser on the gasket itself. Instead, I'd just wipe the gasket with a paper towel, and clean the channel where the gasket fits. I wouldn't put any chemicals on the gasket itself, as chemicals might degrade it's durability/make it brittle. I hope that helps - thanks for watching and good luck! : )
@@L35inColorado Thanks for your response! I just meant the inside of the cover itself (definitely will clean the channel/not clean or reuse the old gasket). For instance, some shops throw them in their parts cleaner tanks before applying the new seal. As a DIY’er I was curious whether it was safe (or necessary) to clean out old caked-on oil with brake cleaner or whether that would affect the oil in the engine in a negative way, even if it was dried with a shop towel, etc.. EDIT: didn’t mean to say “valve cover *gasket*, just “valve cover”, my bad.
OMGosh!!! This is THE BEST DIY video on the entire TH-cam! Detailed, thorough explanations, great editing, great filming, lighting, graphics. Not only the how, but the why and the why not! I came here because I have a P0016 code--"crankshaft position camshaft position correlation bank 1 sensor 1". My Autel code reader gave some possible fixes. I have replaced both crank and cam sensor (because they were easiest to do). Next is replacing the chain tensioner (its leaking oil also)--and while I do the procedure so expertly detailed in this video I can check timing and whether the chain skipped a tooth. Any additional suggestions? Do Toyota timing chains stretch/wear after 200k miles? Thanks again for the video!
So I went counter clockwise 20 degrees like you said then forward till the piston compression was fighting 4x Car runs good After the Counter clockwise motion going forward I heard it zip and ratchet a little bit
Very didactic video! Besides a good instructor you're a very very good PRO. My only concern was about the distance of the tensioner piston once unlocked. If I may give you one advice, you should breakdown the video in parts (Part I, II...). Thank you, you are awesome. Cheers from Brazil!
what you do with the timing chain tensioner was the great help I know you change the timing chain itself on that motor I can use all the torque specs on it I would appreciate it
Great video! Very instructional! The videos that I have seen show tensioners being installed with a gasket in addition to the O-ring on newer models. Question is why is there so much pressure at that point?
Thanks for sharing. That was a great and thorough tutorial. I wish you have one like it on an 2Z-FE or 1Z-FE engines that have the chain tensioner inside the timing chain cover. I need to know the minimum things that need to be removed to reach the tensioner and replace it
Do you mean 2A-FE and 1A-FE engines? If so, those have the tensioner accessed from the outside, like the 1ZZ_FE. What is the application (model & year)?
Thanks! No, the ZR-FAE will be different in a few ways. As far as I know, the ZR-FAE engines use a different gasket for the timing chain tensioner (not an o-ring as shown in this video). Double-check this info for your model, but I believe the part is Toyota 13552-0T020. Also, the valve cover gasket is different, and there are a few more items to disconnect to remove the valve cover. As far as the install: I don't have an FSM for any ZR-FAE, so I cannot say for sure, but it is likely very similar. I hope that helps : ) Thanks for watching!
@@nowa-huta-krk I don't have an FSM for that engine group, so I cannot tell you for certain. If I had to guess, I would think the tensioner release technique is identical or similar, since this is a tensioner style used across several Toyota engine groups - but I cannot say for sure without reviewing the FSM. As mentioned in the video, the method shown (removing the valve cover) is the most conservative, "fool-proof" method. It is the only way to do the repair with certainty of no chain skip, because you visually confirm timing and tensioner release. Also, as mentioned in the video, it is certainly possible to do the job shown in the video without removing the valve cover (I've done it that way before myself, and many mechanics do it that way everyday). There are many youtube videos which show various version of that approach. Personally, I just don't do it that way anymore. I remove the valve cover, because in my opinion, it is just not worth the risk of chain skip, especially when removing the valve cover only adds a few minutes to the job. I don't say it is wrong or bad to do it "blind", but I don't do it that way anymore, personally. I hope that helps : )
this is the best video that I have ever seen . i have a 2002 toyota corolla with the same engine it has a misfire on cylinder 1 and 3 I have chandged everything coils ,injectors,spark plugs,check for vacuum leakes, and redid timing change I have fuel and spark and I still have the same problem please let me know if you have any idea on what it is thanks
Don't worry just yet - the colored links will only line up with the timing marks every several dozen rotations, because the colored links are intended to help with install. You don't actually need the colored links to confirm timing itself - you just need the timing marks on the cam sprockets and crank pulley (not the chain links). For example, you can see in the video at 01:00:07 that while I started with the colored links aligned with the timing marks (as if I just installed the chain), after the very first rotation, the colored links aren't aligned any more - and that's normal. You verify timing using the timing marks. The colored links on the chain itself are mostly for helping when you're installing the chain. It takes lots and lots of rotations on this engine (maybe 50 or more?) for those colored links to happen to line up again with the timing marks - they will NOT re-align with the timing marks every other rotation. So, the fact that the colored links don't align is not something to worry about. Instead, what you want to confirm are the *timing marks* themselves: the marks on the cam sprockets and the mark for TDC (0) on the crank pulley. Review the video at 27:26, and follow along on your engine. If your timing is good, then those marks will re-align every other rotation when the crankshaft returns to 0/TDC, as shown in the video. Don't worry about where the colored links are - just verify that when your crank pulley mark is at 0, the dots on your cam sprockets are aligned. If they aren't, then make another rotation, because if timing is correct they will align every other rotation. If the timing marks on the cam sprockets align as shown when you have the crank in the position shown (every other rotation), then your timing is good! I hope that helps! : )
Thabk you for this incredibly detailed video! I'm certain the leak is coming from my tensioner based on what you said. I bought the part but I'm nervous to start because I can't see the tensioner. It seems very difficult to access. Is it easier to see when the valve cover is off?
Hello, L35 in Colorado. What is the consequence of doing this job for installing a new chain tensioner not according toyota recommendation? I ask because I did this on my daughters 2007 Pontiac Vibe (base) viewing another video that wasn't as detailed as your. It starts up a little rough but goes away after that. Just wondering if that is the issue. I didn't take the slack of the chain and just pulled the tensioner out.
I'm sorry for the late reply - as mentioned in the video, the purpose of properly installing the tensioner by a certain technique is to ascertain that that the tensioner applies tension correctly without inducing chain skip. From what you're describing, it doesn't sound like you have chain skip, as chain skip (even one link) is a pretty big issue that would change your engine timing, so you'd have obvious clues upon initial startup (if it started up at all!). If your '07 Vibe is high mileage, it sounds like you just have the normal amount of chain slack (slack is caused by the chain lengthening over time as the rollers wear), and that chain slack can cause a slight start-up rattle. If you're at all concerned about timing, you can easily check your timing by following the steps in the video. But again - if the Vibe is driving normally, no check engine light, not stalling or failing to start, then it sounds like you just have normal chain wear. I hope that helps - thanks for watching! : )

Thank you for watching, and good
luck with your repair! 👍
Thanks for the great DIY video. I believe I'm experiencing the same problem that is addressed her. I would like to ask if you may have seen oil elsewhere due to Chain-Tensioner leak? I myself had oil all the way up to right side of radiator on the splash guard, on the CV Axle and on serpentine belt. No leaks near filter or pressure sending unit. Nor on the valve cover gasket,etc. I do see oil on the back side near chain-tensioner and below it. Also, how has your chain- tensioner replacement gone? Did the experimental seal replacement seal better? Thank you for your time and I look forward to your reply.
@@UnifiedPeoples So far, so good on my repair, but I really haven't driven too much, so I'll need probably a few months to really determine if the Molykote 55 and alternate/harder o-ring will do anything to prevent the leak.
As for the leak - this leak can make a huge mess, to include the big mess you're describing. However, if you're not sure where the leak is originating, drive the car up on some ramps and slide under with some Super Clean (or other cleaner) and a roll of paper towels, and clean up what you see. Try to get it rather clean - it is worth the effort, and I know it is a pain in the neck cleaning under there! Clean up around the tensioner itself, then check back after a few drives to see if you can definitively locate the source.
Another spot you can get a messy leak is from are the o-rings on the VVT solenoid and camshaft sensor - check out the video link below to see those items (they are super easy repairs, luckily!). Basically, if you're not sure where the leak is originating, it really is worth the time and effort to clean up the oil leak and try to find the source. I hope that helps : )
Here's the video on the other o-ring oil leak sources:

I have been an aerospace educator for over 40 years, I rebuild Porsche 911 engines as a hobby. These are far and above the absolute best automotive repair DIY videos I've ever seen. Teaching/educating is solidly in your DNA! GREAT JOB! Keep it up.
Wow, that's a very kind comment - thank you!
And thank you for being an educator for over 40 years and teaching so many people what you've learned - you've made a wonderful contribution to the whole world! There must be aerospace people all over the world who have learned from you - how cool is that?!
Thanks for watching : )
This is the best repair video I have ever seen! Great videography (picture in picture), easily understood explanation with documentation, thoroughly detailed, narration was pleasant, the pauses with highlighted annotations, time stamps, listed part numbers & you did not talk down alternative ways shown by others on TH-cam. You put a lot of work into this video! Bravo!!!! I really enjoyed watching it. I didn't skip forward at all while watching this video like I usually do. 😃 I am a subscriber for sure.
Wow, thanks for your comment, and thanks for subscribing! I try to put lots of detail in my videos. Thanks for watching! : )
Agreed 100%!! Informative, great cam work, and great little tech tips.....d.i.y.'rs don't understand what damage can be done when messing with timing components. Great job explaining how to get it to cyl #1 TDC BEFORE removal and the detailed camera work showing the timing marks on the crank pulley.....are you really a videographer or an auto tech??.....a bit of both huh?😊 Best repair vid I've EVER seen. No bs!!
Wow this is so amazing, great video , thank you so much,!!
I whis there was honest mechanics like you in my area😊
This video is freaking FANTASTIC!! From the narration, to the camera work, to the pauses w/circles, arrows and text..... pure master class in how-to / tutorial videos! Love it! Also, cool tip for putting the new O-ring on! Toyota and Snap-On probably make a special $300 tool for that - LOL!
Wow, thank you for your comment! Haha - there probably is a special tool, you're right! Thanks for watching : )
I was saying the same thing to my friend about the Producer L35
you are an excellent teaching instructor. by far the most Indepth expiation of a correct trencher in stallion procedure per Toyota thank you
Thank you very much, and thanks for watching!

I am 17 and I just got done rebuilding my 1zz-fe for my Toyota Celica and I have never seen a better teacher. I recently graduated from online highschool because I couldn't stand any of my teachers. But during this past hour and a half I have never been so intrigued and have never learned so much about a process that I have already done. I absolutely love how you go into grave detail in every single portion of this process and take the time to teach the watcher how it functions and how you can better understand each and every mechanical attribute of this system. Thank you for taking the time to add in every detail and edit these videos we all appreciate it!
Wow, that is outstanding work - congratulations on your 1ZZ-FE rebuild! You should be very proud for having completed such a technical endeavor - well done, very well done! Great job!!
I'm so glad that you liked the video, and thank you for watching! : )
You have made one of the best repair videos I have seen on this platform. Fantastic attention to detail. Great job. 👍👍👍👍
Thank you, and thanks for watching! : )
VERY thorough explanation of the whole process! I wish you made ALL the auto repair videos!
Wow, that's very kind - thank you, and thanks for watching! : )
Thanks
Wow! Thank you so much for the SuperThanks! : )
The tensioner is a culprit on the 2ZZ GE (Celica) engine and the O-Ring leaking. However, many replace the O-Ring and/or tensioner and it still leaks. Usually the timing cover gasket is the culprit then. The gasket dries out and cracks and leaks oil. However, always make sure some RTV is applied in key areas according to manufacturer tech book and correct torques when refitting timing cover. Otherwise the leak can come back. Brilliant step by step video here. Wish many people took the time like you have to explain clearly.
Yes, unfortunately that is a fairly common problem on the 2ZZ-GE engines as they get older. The 1ZZ-FE has a form-in-place gasket (FIPG, gasket-maker, RTV) for the timing case cover, and it seems to be a bit more durable as timing cover leaks are less common on the 1ZZ-FE. Thanks for watching and for adding your tips! : )
Bravo! I already know how to do this on my Vibe ( same engine) but I learned several things and heck was “infotained” for an hour. I will use this as inspiration for a video in my line of work to teach people who already know how to do something their way ,how to do it the right way going forward. And why it’s important. My multi billion dollar business could learn some best practices from you!
Thank you! That's great that you're making a video to show the proper techniques for your field's applications: I'm a big fan of detailed videos, especially for technical operations because technicians can watch and re-watch a detailed video as a sort of practice for the real work ahead. A good video can give a technician more confidence for executing a new operation, and for common operations, a good video can explain why a certain technique/step is necessary even when it is not apparent why it's necessary, and may even seem like "a waste of time".
That's basically why I did this video - I noticed many people wondering online as to why a conservative mechanic might price this job higher and coupled with a valve cover gasket replacement, while many other mechanics don't. Some people mistakenly thought that the first mechanic was just "ripping me off!" because they didn't understand why he'd remove the valve cover when they've seen several videos on TH-cam of regular people doing the tensioner replacement in 15 minutes, without removing the valve cover and "everything was fine".
So, I just wanted to explain that while, yes, it is possible to do the job in 15 minutes without removing the valve cover (as shown in many other videos, and as even often done in shops by technicians, including Toyota techs), ultimately the person paying the bills and making the decisions needs to know that executing the repair in that way ("blind") comes with the very low-probability but very high-impact risk of timing chain skip on an interference engine, which typically causes catastrophic engine damage when it occurs. Here is an example, with a picture:
www.toyotanation.com/threads/broken-cam-chain.1466994/
An average DIYer might not know that such catastrophic damage is possible from "such a simple DIY on youtube", but a technician or mechanic ought to know. A conservative tech or mechanic is simply not willing to risk chain skip on an interference engine, period, so he will spend the extra time and gasket to "just do it right" and simply remove the valve cover so he can see what he's doing, confirm tensioner release and double-check timing, and therefore eliminate the risk of catastrophic damage. Conservative mechanics also prefer to resolve doubt as much as possible/reasonable rather than to rely strictly on chance, so the visual confirmation resolves the doubt, too.
So - anyways - a big thanks to you for making videos for your people, too, so that they can do their operations well and understand why they're doing what they're doing! And thanks for watching : )
I’ve been watching Toyota repair videos for years, this is the best one I’ve ever seen, very detailed and easy to understand, thank you so much 💙

That video is outstanding: there are a few little differences since he's working on the oldest version of the 1ZZ-FE (for example, you wouldn't hone the cylinders on the later version 1ZZ-FE found in the Matrix), but overall it is a gem video. I hope that helps - thanks for watching! : )
Holy crap! This is the best DIY car repair video I have EVER seen on TH-cam. Thank you SO MUCH for putting the time and effort into making this. The notes and annotations we super helpful.

Watched your door check video for my '04 Pontiac Vibe a number of years ago, and here I am again! You make absolutely excellent videos - thank you for what you do. Here's to many more miles out of my 1ZZ-FE! :D
I love your attention to detail!! I wish I could find a mechanic like you here in Waco Texas. I am disabled in a wheelchair and I take my Toyota Sienna to the dealership, but I always worry who is working on my van. I enjoy all your videos!!
Thanks! : ) I know what you mean about shops: it's difficult to find a shop to trust, unfortunately. I'm not familiar at all with the Waco market: you might be able to find some suggestions in the Sienna or general Toyota forums about independent shops that people in Waco trust. Hopefully your Sienna doesn't require too much repair - they are reliable vans that last a long time!

I'm doing DIY repairing my corolla. At first time, it started cleaning manifolder intake, and then I am getting disassemble the engine, and need some information how to set up crank and camshaft, your video clearly shows how to set up crank and camshaft, I am searching another video how to remove engine block...LOL. Thank you for your video. 😀
This below is one of the best videos I've seen on the 1ZZ-FE - it doesn't show the block removal, but it shows a lot of other great info:
th-cam.com/video/A595LR4SQpI/w-d-xo.html
There are some differences between the early 1ZZ-FE (like the one shown in that video) and the newer 1ZZ-FE (for example - you don't the cylinders on the newer engines), but overall that video is a real gem, if you haven't seen it!

Wow, I did this procedure without watching this first. Did the counter clockwise clockwise move listening for the soind. But seeing this, just made me realise that i got lucky, results could have been disastrous. Thanks for explaining this procedure in detail.
Great attitude & video! My 03 has 260K miles and I'll soon be opening it up to check valve clearances. Six exhaust and two intake valves needed adjustment at 170K. Those last two exhaust valves are a concern since you can burn a valve if you run them too tight for long and they usually get tighter as the seats wear. Glad I got lucky when I replaced the tensioner over a decade ago.
Thanks, and thanks for adding your tips! : )
This is the work I need in my 2006 Corolla with 285K km…the engine is soaked in oil from behind by where the timing chain tensioner and wet oil on ignition coil so valve cover gasket needs to be replace for sure, I’ve notice when I replaced the spark plugs….after watching your video I’m less intimidated to do it myself….thanks for your video.

Thanks for making this video !!! Chain skip is a really big risk for people who have older Corollas with lots of miles on them since the timing chain will be more stretched and have a much greater risk of having the chain skip a tooth. I have a slight leak on my tensioner and instead of changing the O-ring I simply added a 236 ml bottle of 'AT-205 RE-SEAL' to the engine oil when I changed my engine oil and that seems to have fixed the oil-leak problem for me.
Detailed video with good tips. Thanks! Also, some people use a thin coat of RTV on the tensioner O-ring to help prevent future leaks.
Yes - some people do use RTV: I haven't heard of people using it on the o-ring itself, but on the flange I have certainly seen that. Personally I don't use RTV because it just tends to make a mess for the next person. Here's the perspective from a Toyota tech on the matter:

What a well documentated and beautifully executed tutorial. Love your video style and your calm soothing voice narration. Subscription worthy 100%. Very surprised it leaked again....what is going on with Toyota quality? At least that tensioner doesn't require a grenade pin and doesn't require Herculean pressure to push it back in like some Subaru ones.
Haha, yes this tensioner is much easier to work with, and it is nice that it is accessible without removing the chain cover. As far as the o-ring leak - I'm not sure what's going on, but unfortunately it has become a common issue. From what I understand, the factory installed o-rings (ie, installed in '03 - '08) lasted quite a long time and typically didn't start leaking until 10 years or more later. But at some point, the quality/supplier must have changed, because these o-ring leaks too often. I hope my experiment works! : )
Thanks for your comment and thanks for watching!
Brilliant! A lot simpler job than my last chain + tensioner job (2010) on my OM603, 6cyl Benz Diesel. Thanks for great tips.

It's been a year since you posted this video but thank you very, very much for doing it. I followed the video's fantastic directions and installed a new chain tensioner last weekend with no drama. I opted to use a screwdriver to release the chain tensioner, which was very easy and guaranteed no chain skip. Please let us know if the O-ring you installed with the moly grease is better than a Toyota O-ring.
It's relatively still new but, if possible, please post any videos on how to do maintenance on a Toyota's hybrid system and the A25A-FXS engine.

Excellent work, this level of detail gives DIY’ers the confidence to get these jobs done right. Would you recommend cleaning out the valve cover gasket with brake cleaner or degreaser before reinstalling?
Thanks! If you mean cleaning out the channel where the valve cover gasket fits with brake cleaner, then yes, you can do that. If you don't have brake cleaner you can use degreaser, or even just a paper towel to remove the old oil before installing the new gasket - just something to get it clean so you don't mistake old oil as a new leak after the repair.
If you mean that you're re-using the valve cover gasket (like I do in the video) and you're asking if you should clean the gasket itself - then, no, I wouldn't use brake cleaner or degreaser on the gasket itself. Instead, I'd just wipe the gasket with a paper towel, and clean the channel where the gasket fits. I wouldn't put any chemicals on the gasket itself, as chemicals might degrade it's durability/make it brittle.
I hope that helps - thanks for watching and good luck! : )
@@L35inColorado Thanks for your response! I just meant the inside of the cover itself (definitely will clean the channel/not clean or reuse the old gasket). For instance, some shops throw them in their parts cleaner tanks before applying the new seal. As a DIY’er I was curious whether it was safe (or necessary) to clean out old caked-on oil with brake cleaner or whether that would affect the oil in the engine in a negative way, even if it was dried with a shop towel, etc..
EDIT: didn’t mean to say “valve cover *gasket*, just “valve cover”, my bad.
Very informative. Thank you for posting this video.

OMGosh!!! This is THE BEST DIY video on the entire TH-cam! Detailed, thorough explanations, great editing, great filming, lighting, graphics. Not only the how, but the why and the why not! I came here because I have a P0016 code--"crankshaft position camshaft position correlation bank 1 sensor 1". My Autel code reader gave some possible fixes. I have replaced both crank and cam sensor (because they were easiest to do). Next is replacing the chain tensioner (its leaking oil also)--and while I do the procedure so expertly detailed in this video I can check timing and whether the chain skipped a tooth. Any additional suggestions? Do Toyota timing chains stretch/wear after 200k miles? Thanks again for the video!
Awesome 💯... The tinplate is a good idea! Wow!
Thanks, and thanks for watching! : )
oh my!! excellent video!!!!!! all your videos are amazing!!!!!! excellent detail also!!!!!!!
Thank you, and thanks for watching! : )
So I went counter clockwise 20 degrees like you said then forward till the piston compression was fighting 4x
Car runs good
After the Counter clockwise motion going forward I heard it zip and ratchet a little bit
Great job on your DIY - thanks for watching! : )

Thank you for watching! : )
Question, am I correct to use brake cleaner on the inside of the valve cover? If so, should I then give it a good rinse with water and dry? Thx
Very didactic video! Besides a good instructor you're a very very good PRO. My only concern was about the distance of the tensioner piston once unlocked. If I may give you one advice, you should breakdown the video in parts (Part I, II...). Thank you, you are awesome. Cheers from Brazil!
what you do with the timing chain tensioner was the great help I know you change the timing chain itself on that motor I can use all the torque specs on it I would appreciate it
Great video! Very instructional! The videos that I have seen show tensioners being installed with a gasket in addition to the O-ring on newer models. Question is why is there so much pressure at that point?
Thanks for sharing. That was a great and thorough tutorial. I wish you have one like it on an 2Z-FE or 1Z-FE engines that have the chain tensioner inside the timing chain cover. I need to know the minimum things that need to be removed to reach the tensioner and replace it
Do you mean 2A-FE and 1A-FE engines? If so, those have the tensioner accessed from the outside, like the 1ZZ_FE. What is the application (model & year)?
Hi perfect video,I have question for engine 1.8 ZR-FAE valvematic is same procedure like on video?
Thanks! No, the ZR-FAE will be different in a few ways. As far as I know, the ZR-FAE engines use a different gasket for the timing chain tensioner (not an o-ring as shown in this video). Double-check this info for your model, but I believe the part is Toyota 13552-0T020.
Also, the valve cover gasket is different, and there are a few more items to disconnect to remove the valve cover.
As far as the install: I don't have an FSM for any ZR-FAE, so I cannot say for sure, but it is likely very similar.
I hope that helps : ) Thanks for watching!
Thanks for replying,yes you right but I talking about procedure of release tensioner and I can do this with rocket cover on is a mind (blind)?
@@nowa-huta-krk I don't have an FSM for that engine group, so I cannot tell you for certain. If I had to guess, I would think the tensioner release technique is identical or similar, since this is a tensioner style used across several Toyota engine groups - but I cannot say for sure without reviewing the FSM.
As mentioned in the video, the method shown (removing the valve cover) is the most conservative, "fool-proof" method. It is the only way to do the repair with certainty of no chain skip, because you visually confirm timing and tensioner release.
Also, as mentioned in the video, it is certainly possible to do the job shown in the video without removing the valve cover (I've done it that way before myself, and many mechanics do it that way everyday). There are many youtube videos which show various version of that approach.
Personally, I just don't do it that way anymore. I remove the valve cover, because in my opinion, it is just not worth the risk of chain skip, especially when removing the valve cover only adds a few minutes to the job. I don't say it is wrong or bad to do it "blind", but I don't do it that way anymore, personally.
I hope that helps : )
I rotated my 1zz without the tensioner installed very slowly could I have jumped a tooth? Thx
It is unlikely, but it is possible. Did you hear/feel anything unusual while rotating the crankshaft, and how much did you rotate it?
this is the best video that I have ever seen . i have a 2002 toyota corolla with the same engine it has a misfire on cylinder 1 and 3 I have chandged everything coils ,injectors,spark plugs,check for vacuum leakes, and redid timing change I have fuel and spark and I still have the same problem please let me know if you have any idea on what it is thanks
Aw man, I'm sorry that's happening to you - have you checked compression on those cylinders?
Thanks for getting back to me , well I pulled the valve cover rotated by hand with tensioner and the colored links don’t line up 😞
Don't worry just yet - the colored links will only line up with the timing marks every several dozen rotations, because the colored links are intended to help with install. You don't actually need the colored links to confirm timing itself - you just need the timing marks on the cam sprockets and crank pulley (not the chain links).
For example, you can see in the video at 01:00:07 that while I started with the colored links aligned with the timing marks (as if I just installed the chain), after the very first rotation, the colored links aren't aligned any more - and that's normal. You verify timing using the timing marks.
The colored links on the chain itself are mostly for helping when you're installing the chain. It takes lots and lots of rotations on this engine (maybe 50 or more?) for those colored links to happen to line up again with the timing marks - they will NOT re-align with the timing marks every other rotation. So, the fact that the colored links don't align is not something to worry about.
Instead, what you want to confirm are the *timing marks* themselves: the marks on the cam sprockets and the mark for TDC (0) on the crank pulley. Review the video at 27:26, and follow along on your engine. If your timing is good, then those marks will re-align every other rotation when the crankshaft returns to 0/TDC, as shown in the video. Don't worry about where the colored links are - just verify that when your crank pulley mark is at 0, the dots on your cam sprockets are aligned. If they aren't, then make another rotation, because if timing is correct they will align every other rotation.
If the timing marks on the cam sprockets align as shown when you have the crank in the position shown (every other rotation), then your timing is good!
I hope that helps! : )
@@L35inColorado do you have any videos on replacing that stupid vvti cam gear the unlocking and locking installation process? Thank you
Thabk you for this incredibly detailed video! I'm certain the leak is coming from my tensioner based on what you said. I bought the part but I'm nervous to start because I can't see the tensioner. It seems very difficult to access. Is it easier to see when the valve cover is off?
Fantastic vidéo. Exceptionnel instruction
hola buenas noches excelente video bien explicado me ayudó mucho saludos Venezuela
Gracias - y gracias por ver! : )
Hello, L35 in Colorado. What is the consequence of doing this job for installing a new chain tensioner not according toyota recommendation? I ask because I did this on my daughters 2007 Pontiac Vibe (base) viewing another video that wasn't as detailed as your. It starts up a little rough but goes away after that. Just wondering if that is the issue. I didn't take the slack of the chain and just pulled the tensioner out.
I'm sorry for the late reply - as mentioned in the video, the purpose of properly installing the tensioner by a certain technique is to ascertain that that the tensioner applies tension correctly without inducing chain skip.
From what you're describing, it doesn't sound like you have chain skip, as chain skip (even one link) is a pretty big issue that would change your engine timing, so you'd have obvious clues upon initial startup (if it started up at all!). If your '07 Vibe is high mileage, it sounds like you just have the normal amount of chain slack (slack is caused by the chain lengthening over time as the rollers wear), and that chain slack can cause a slight start-up rattle.
If you're at all concerned about timing, you can easily check your timing by following the steps in the video. But again - if the Vibe is driving normally, no check engine light, not stalling or failing to start, then it sounds like you just have normal chain wear. I hope that helps - thanks for watching! : )
