From Kenya, thanks alot mayo cars Dr your videos are very informative and helpful,I have learned a lot from watching your videos, thanks may God grand you more energy to continue with the good job you are doing,🇰🇪......... thanks alot
Very well done job. Big ups to you and thank you for putting these videos together. I wish there were good mechanics here in my part of the world like you. Continue to make videos to help us car owners so that we can diy or at least have some ideas of what might be happening when a certain symptom arises on the car.👍👍👍👍👍
Thanks for the hint on timing chain diagnosis, I took the valve cover off and saw top chain guide was fine and chain was still tight. Turned out my noise was alternator bearing and water pump. The engine noise sounded the same as a failing timing chain.
OPQRST: Onset, when and how did it start ? Provoking factors, better or worse, Quality of noise, grinding, rub, banging, Radiation to another location, Site of the problem, Timing of the problem (cold start, certain rpm, shifting ?) Then History of work recently, Inspection, instrumentation,
@@MayoCarsDR yes I know that otherwise goodluck getting it in. Anyways i found it did release even though I didn't hear the clicks. Guess engine took time to settle everything back into place. But its running like a top and the click is gone. That engine was torn into by someone else because the timing marks on the chain never matched up to the cams so I made my own on the chain.
Great video, really nice details. I have a 2011 Toyota Highlander with the 2TR-FE is a 2.7 L engine. It has a strong rattle noise in the engine bay, which is loudest when in Drive or Reverse with the brake on and apply and let off the gas to make the engine go from low revs to higher revs and back to low revs. The car has 265,000+ miles on it. I use synthetic oil and change it every 3,000 to 5,000 miles. Possible problems could be with chain tensioner, chain dampener (if it has one), throttle body, alternator bearings, engine mount, VVT gears and/or VVT actuator, water pump, etc. Can you narrow the list down at all? Also, other friends with high mileage Toyotas have suggest do an engine oil flush (AutoZone or Amsoil) but I don't like that idea too much. Any thoughts? Thank you again for the great video.
My 03 corolla has that same groaning sound when in gear and idling. Sometimes does it in neutral at idle also. when RPM's come up a bit, sound seems to goes away. Does it with hot or cold engine. Was the top guide (im assuming you called it the engine dampener) broke off when you first showed the loose chain on the first engine? Or was that an additional part added? A bit confused on that part because if it WAS there on the first engine, where did it end up? in the oil pan? Or are you saying it was worked on previously and someone failed to reinstall it afterwards? Ours is making this sound and its very concerning. Need to try and fix it asap myself if possible. IF its just replacing the Crankshaft tensioner, Im seeing a lot of videos doing it without pulling the top cover, which didn't look to bad. OR, do I need to pull the cover and verify that I have an engine dampener in place along with changing the Tensioner? REALLY hope you find this comment and can assist if possible. Thanks!!
Yes, you can replace the tensioner without removing the valve cover. The purpose of removing the valve cover is to check inside that everything else is OK
What year was this Corolla please? I see it only has barely over 200,000 km on it isn’t that pretty early for a tensioner to go bad? I have 275,000 miles on my 09 Corolla all still seems quiet thankfully
I Have a 2010 with only 30K miles and the tensioner is bad! The spring gets weak over time and it needs to be replaced! The Miles have no impact on when it goes bad! Lexus Recalled this Tensioner on their VVT engine because it is a safety hazard but Toyota feels you have air bags and you should be fine :O( I just got back from the dealer and got a mechanics opinion that If You can install this Part Be very careful not to alter the timing while turning the engine without the tensioner being released As specially if you have high miles and the timing chain has stretched so I wondered if you could install the tensioner with the clip released? One Comes out and the other goes in without turning anything and the Mechanic says you CAN! No need to remove the valve Cover!
@@dugeep Bit of tech info for your help. The tensioner for the timing chain is oil pressure based there is no spring that is something very old. The passages for the oil to this system are very small and if oil is not changed often in a low mileage car it will varnish and gum up, restricting passages and cause detriment to the tensioning system just like building a plaque in arteries to the heart. This is why your tensioner system has gone bad.
I have a 2013 Corolla 1.8, it has a slight crackling sound at rpm1.5 to 2, and when running, the car is considered new, and it has less than 50,000 km of mileage. Could the reason be from the chain tensioner?
I noticed in your Video that one Corolla (SILVER One) had the Chain Damper already installed and the other corolla the (Dark Grey One) Did Not! I called my local dealer and they said that my 2010 has the Damper P/N 13562-0T020 but I replaced the Tensioner thanks to your Video (Thank You So Much!) but My chain is still hitting the Cover both when you first start the car and on Acceleration! My 2010 Corolla only has 36k miles and I didn't think anything was wrong with the tensioner I took out comparing the two, Latching and Unlatching them they seemed the same to me and after installing a new one made no difference, My Question is: Is It possible that the Chain damper is not in there even thou Toyota Dealer Says It is? Because if the Damper is in there NO WAY COULD THAT CHAIN Hit the Cam Cover! I guess I might have to take the Cover Off But What year is the Dark Grey Corolla in your Video? It looks just like my LE 2010? Thank You :O)
Not an expert, but I've been preparing to do this and from what I've seen there's hardly any oil that comes out when changing the tensioner. I would reccomend to change time the tensioner change with your next oil change or if you're very careful not to let contaminates in you could just top up that small amount that comes out. My main concern would be with contaminates getting in and possibly clogging up the holes in the variable valve timing system or something.
Thanjks for the video. The best thing about this channel is to explain everything and at the end showing before and after. Subscribing.
You welcome
im truly grateful in subscribing your channel because im truly learned a lot about toyota engine...thanks
Thanks for comment

Thanks for comment
I have the same issue my brother said it’s not a big problem.
How did you line up the chain to the marking. Dealership will charge arms and legs.
Thanks for the video and Happy New Year.
Thanks for the hint on timing chain diagnosis, I took the valve cover off and saw top chain guide was fine and chain was still tight. Turned out my noise was alternator bearing and water pump. The engine noise sounded the same as a failing timing chain.
It was 07 corrola same as yours
If you remove the drive belt and start the engine, you should know if the noise is coming from inside the engine or something else
@@MayoCarsDR that's a great idea 👍
Hi m8. I have a similar noise. What was eventually the cost for you?
@@gloryths around $350 for new water pump and alternator from car wreckers
Thank you, just learned another thing.

After how much mileage of engine, tensioner can wear up to point where it does not function properly
MaahAllah
I just did the vvti replacement, I need to recheck to see if the new tensioner released. It's all in time, getting a tick though...
The chain tensioner has to be released after installation.
@@MayoCarsDR yes I know that otherwise goodluck getting it in. Anyways i found it did release even though I didn't hear the clicks. Guess engine took time to settle everything back into place. But its running like a top and the click is gone.

It is not appropriate to tell anything like this, can you make a video and send it to me
@@MayoCarsDR Yes can do. Will send you the link where I upload it. Thank you
What's the valve cover screw torque? Does it must be tightening from center to the sides? Thank's great video.

I see the video of the manual. 10 Nm all 13th screws.
Hi, I just want to know what if not replacing it, will it damage the engine when timing chain hitting the top cover? Thanks
Yes
very good video
Thanks for comment
👏❤️
Good quality work manship money well spent I would like to Go to the who do good work on my car
Thanks for comment
Could you please let me know how to get to your place of work
The timing chain look like its loose before even removing the tensioner. By changing the tensioner, will fix loose chain ? Thanks for all the help
If the chain sleepers are fine
thanks for video.
why is top chain guide missing ? is it broken inside engine ?
Anyone who has worked on this engine before has not installed these part
Fantastic
Thanks for comment
How many miles should this be replaced? Or does it just depend on if the engine is making this noise
Thanks for comment,it just depend on if the engine is making this noise

Replace the chain tensioner and open the valve cover to make sure nothing else is wrong
ruclips.net/video/pYU75JprB5k/видео.html
I suspect my 2010 Toyota Corolla has that same issue. Can I just replace the tensioner without opening up the top? See if that works?
Yes
I never knew you could start the car with the belt off, can you replace the chain tensioner without removing the valve cover
Yes, you can replace the tensioner without removing the valve cover. The purpose of removing the valve cover is to check inside that everything else is OK

Yes
Yes replace chain tensioner and check it
Can you adjust the chain with put opening the engine head? It the chain tightening by you using the wrench near the compressor pulley?
What would cause small vibration at idle?
Throttle body or bad engine mountain
Really nice but the timing was off and the chain skipped two teeth and you didn't correct it

Damper 13562-0t020 and 13562-37020 same no problem
Is your car's chain tensioner correct?
Dark grey Corolla 2014 model
If the sleeper damper is bad, the chain tensioner will also be bad

Probably a dumb question, do you have to drain the oil?
As nice as it was to get a heart instead of an answer id still like the answer

There is still some little sound
Min 4:44 anyone see that face figure on the valve cover?
The timing chain was rubbing here
I see that, but I also saw a face figure with the oil lol
