Thank you for watching, and good luck with your repair! 👍

[@UnifiedPeoples]

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.

[@L35inColorado]

​@@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: kzbin.info/www/bejne/kJq1oHWIZ5eXbMk

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 KZbin. 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!!

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!

[@L35inColorado]

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! : )

[@92Pony]

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!

[@L35inColorado]

Wow, thank you for your comment! Haha - there probably is a special tool, you're right! Thanks for watching : )

[@somap8380]

I was saying the same thing to my friend about the Producer L35

[@craig357]

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.

[@L35inColorado]

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! : )

[@albertluker3032]

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!

[@L35inColorado]

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 KZbin 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 : )

[@L35inColorado]

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! : )

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.

[@menguardingtheirownwallets6791]

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.

[@L35inColorado]

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 : )

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.

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.

[@L35inColorado]

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!

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!

[@vapewilder7843]

I know this video is a year old, but at about 10:22 you said you did a rebuild on this. Did you mean you rebuilt the engine or just top end? I'm just curious. Thanks.

[@L35inColorado]

Thanks - by "rebuilt" I meant that I did all the head work, piston rings, and rod bearings, but I didn't do a full rebuild (no work on the crankshaft or main bearings). To be more detailed - I bought the Matrix for very cheap in 2018 after it had been sitting about 6 months or more due to a blown head gasket: the head gasket failure was apparently caused by a shop tech who forgot to plug in the electric fan, which caused an overheat. Mileage was 196K miles, and the original owner had never had any issues with it since new. To repair the head gasket problem, back in 2018 I removed the head and had it professionally milled (there was some pretty good warpage and the machine shop had to remove a bit more than I was expecting), but the block appeared to be re-useable/within spec. But I wasn't certain that the block was actually still good, so I hedged. So, I just removed the oil pan so that I could remove the pistons to the rings and rod bearings, since those parts are were cheap enough and these engines do have issues with oil passage obstruction at the piston head holes. I didn't split the block, and I didn't remove the crankshaft, though. I didn't hone the cylinders, either, because I learned at that time that this Matrix has the "newer" 1ZZ-FE version that has specialized cylinder liners that apparently you don't want to hone. I lapped the valves and replaced all the valve stem seals, and all the other seals/o-rings I could; the camshafts didn't require any work and valve clearances were good. I put everything back together (with a standard head gasket), and she's been running great since, and I've put about 30K miles on since. I did that work with the engine in place and didn't remove the timing cover, either (I suspended the chain to keep it on the crank sprocket while doing the other work): the reason I didn't go deeper was because I really wasn't sure that the block was actually good (seemed to be, but I wasn't sure) and didn't want to regret throwing parts at a bad block. But apparently the block was good enough! That's a very long answer to your question, but I hope that answers it! : ) Thanks for watching, and if you're wondering about a video for the sort of "rebuild" I did, check out this outstanding video: kzbin.info/www/bejne/d2acZn-IabiEpqs Thanks for watching! : )

[@keepcalmandfarmon5401]

OMGosh!!! This is THE BEST DIY video on the entire KZbin! 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!

[@johnmcminn9455]

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

[@L35inColorado]

Great job on your DIY - thanks for watching! : )

[@kevingok]

What's your opinion of the Molykote 55 so far? Do you think it has helped or too early to tell?

[@ericvannielsen]

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?

[@L35inColorado]

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! : )

[@ericvannielsen]

@@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.

[@larryangel9204]

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

[@nowa-huta-krk]

Hi perfect video,I have question for engine 1.8 ZR-FAE valvematic is same procedure like on video?

[@L35inColorado]

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]

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)?

[@L35inColorado]

​@@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 : )

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

[@Cstoreri]

[@L35inColorado]

Thank you, and thanks for watching! : )

[@rahalati]

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

[@L35inColorado]

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)?

[@314Draken]

I have a leaking timing cover and was wondering what the process is to remove/install the harmonic balancer and timing chain tensioner to avoid the chain form jumping? Should the harmonic balancer be removed(using impact gun) before the timing chain tensioner as this would mean that the chain is tensioned and it's safer if the engine were to rotate? I've seen some people use zip tie to tension the chain on the exhaust sprocket to avoid the chain to skip during the work. Any advice regarding this? Should I zip tie it before removing the tensioner? When should I remove the zip tie? After rotating the crankshaft counter clockwise to dislodge the hook on the tensioner and then clockwise to engage the tensioner? Lastly I'm thinking of tightening the harmonic balancer once the tensioner is engaged.

[@tacosdelengua5051]

You used RTV where the timing chain cover meets the head to prevent oil leakage through that little gap... have you considered using a bit of RTV on the base of the tensioner (certainly not on the o-ring itself), where it mounts on the block, as insurance against future o-ring leaks?

[@L35inColorado]

I am aware that some people do that - the pro's and con's have been discussed at length on the boards, especially the Toyotanation.com forum, for example here: www.toyotanation.com/threads/diy-2003-2008-corolla-matrix-pontiac-vibe-1zzfe-timing-chain-tensioner-replacement.1255385/ www.toyotanation.com/threads/timing-chain-cover-oil-leak.1689219/ www.toyotanation.com/threads/timing-chain-tensioner-replaced-leaks-more.369697/ Those experiences show some limited success with that approach, but generally it doesn't work out so well and tends to just add a mess to the leak, because the real issue is that darn o-ring. So personally, I don't use RTV for the chain tensioner because unless I have a very good reason to, I will generally stick to the FSM and adhere to the original design on components, and the original design on this is that the o-ring seals the bore. It is true that for whatever reason, Toyota hasn't got it quite right with their choice to use an o-ring to seal this bore in particular, because it leaks so often (in other applications they used a gasket which seems to have leaks much less often). I'm hoping my "upgraded o-ring" will solve the problem, but we'll see! Personally, RTV would pretty much be my last resort because RTV is indeed a real bother to clean up. But I can certainly understand that people get frustrated with this recurrent leak and resort to RTV - it's just not something I'm willing to do yet : ) I hope that helps - thanks for watching!

[@tacosdelengua5051]

@@L35inColorado Thanks for the reply. With that in mind I'm going to skip the RTV and just go with your / the FSM's approach for when I do mine for the first (and hopefully last) time. Awesome channel btw, keep up the good work.

It is unlikely, but it is possible. Did you hear/feel anything unusual while rotating the crankshaft, and how much did you rotate 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?
