Thnak you so much for this video, i took my car to the shop and they told me that my car needs a new timing chain kit and that would could my $2250 for parts and labor, but after watching this i ended up only spending a $100 to get the tensioner replaced and its working perfectly fine now. Thank you again Mayo Cars DR
Thanks. Changed the tensioner. During acceleration engine was getting very loud. Still the same.😢 Sound is there. Also check engine light came on. Any idea? I have exactly the same problem as you showed.
Hi brother, mine makes this sound only at startup and ideal. Ehen i accelerate it does not make the sound. I bought the tentioner already but after watging this video i think its not the problem. Can you advice please ?
My noise is very similar but I have to be off the throttle and at 2000 rpm. I hear this noise when decelerating. Could this be my problem? 03 corolla. 1.8l. I actually had valve cover off today and the chain had a little bit of slop but only like a .25 to .50 of an inch. Seemed tight to me
Thanks, my Yaris suddenly sounded like this today at 260,000 km. Idles fine, only hear it when I am driving and accelerating. Pretty sure it isn't water pump, and I know it isn't the bearings in alternator. I will give this try. I appreciate you taking the time to record the sound. Very helpful. Edit: I discovered that the 1.5 engine in a Yaris/Echo has an internal tensioner that is not the same as Corollas, Matrixes etc. One of the dealer techs agreed my engine sounded like a timing chain, but he'd also heard water pumps make this noise and he has never replaced a chain or tensioner on the 1.5 engine. So, I went for it today and jacked it up, and took the serpentine belt off. Yup, i could feel the rough bearing on the water pump right away. So, if others come across this sound, you can quickly narrow it down by removing the serpentine belt and feeling the alternator, water pump, and AC compressor bearings. If they feel a little rough or make any noise as you spin them, that's probably the culprit. If you can't tell, start the engine up for a minute with no belt and listen. If the sound is still there it isn't bearings driven by the belt - it is likely the timing chain slack hitting valve cover or dampener. I replaced the water pump as described by others and all is quiet again. Was about a 3 hour job and a little difficult to get at with big hands.
Hey thanks for the comment, i have the same yaris 1.5 2009 and was wondering about this, I have replaced my water pump, so the tensioner in the yaris is different?
@@makeit.primetime99 When I removed the belt to water pump and turned it I could just barely feel rough bearing. When I started it up without pump connected, it was silent. It was the bearing after all. I was so sure it was the tensioner, that I'd ordered one one from Toyota. As soon as I saw it, I realized it was completely different. That 1.5 Yaris engine has an internal tensioner that is much more difficult to replace and that's why there are no YT videos on it. You have to pull the pulleys and timing chain cover off to get to it. So, I returned it at 10% restock charge, went to the local part store and bought a water pump. OOps so long ago, I forgot I've already gone through this above.
On my 2010 Toyota Corolla repair manual said to release tensioner hook turn crankshaft to counterclockwise then clockwise. Now I have 2016 Toyota Corolla 2xr-fae should turn clockwise to release the hook
I bet you can't diagnose my 2003 Toyota matrix that's sending code p300 and sounding the way it does wit the video a send to you if you read my comment and reach out if you do I'll subscribe just ask for the video. When you do diagnose the problem do a TH-cam video complimentary of me it's all yours, I'm waiting.
The P0300 engine code indicates a misfiring cylinder problem in your vehicle. The misfiring happens when insufficient fuel is burned or when the spark plug gets damaged. In addition, it can damage your car's catalytic converter in extreme conditions.
My car started making a slight noise on start up when the engine is cold.it stared after I changes the oring on my chain tensioner but I didn't put it back in at tdc could that be why. And I also when and bought a new tensioner from toyota today to see if it helps bur it still makes the same noise.its on the 1zz engine

Music was too loud and unnecessary. More importantly you totally failed to mention. The engine crankshaft must be turned CLOCKWISE to allow the tensioner to extend to the proper length. It's in the instructions of the tensioner.
Muy Bien video ...gracias ,una pregunta ,cuando pones El chain tensioner ,no necesitas mover El crankshaft para que queden. Posicionados Las valvulas ..y la varilla del tensor tiene que quedar afuera o en su posicion normal ...gracias de antemano
Al parecer el tensionador se coloca con la varilla (embollo) adentro y enganchado. A la hora que giras la cadena con el crankshaft manualmente, se libera el embolo cuando suena ese "click" que se demuestra en este video.
thanks...you directed me to this video from another one I watched (of yours) with similar symptoms. I will do as you described and pull the valve cover and swap the tensioner. From looking at videos, i don't think I have that dampener piece, but will verify when I pull the cover. My engine code is the 1zz-FE according to the VIN decoding I did.
My Corolla engine is 2NZ-FE and the tensioner is inside the engine. Can I change the tensioner while the engine is on the car or should remove the engine completely
Thank you so much for your helpful videos 🙏 What kind of product do you apply to the tensioner gasket, and is this the same product you use on the valve cover gasket?
I'm having similar symptoms of engine noise after 2k rpm, the fiat Punto MjD, clocked 3.52 lakhs kms. Will check with chain tensioner. Thanks for the video
I wish I k ew this two days earlier. Just now TH-cam started to suggest them to me. TH-cam algorithm has failed me. I paid $700 in total to fix it with used spare parts otherwise it would be skyrocket cost.
السلام عليكم قمت بتبديل بآكن الرأس ولكن بعد تطبيق المكينة اشارت لمبة التشيك فحصتها عند كهربائي سيارات فقال ان التيمت غير موزون ولكن السيارة هادئة وكل شيء فيها طبيعي .. ما هو سبب إضاءة لمبة التشيك برأيك ............. Peace be upon you, I changed the head machine, but after applying the machine, the Czech bulb indicated that it was checked by a car electrician, and he said that the timt is not balanced, but the car is quiet and everything in it is normal. What do you think is the reason for lighting the Czech bulb
I had the same sound and checked the timing chain tensioner, The plunger was stuck back in the body of the tensioner and the body was also cracked along its length. I am sure it would have broken along the crack lines and fallen into the engine. I replaced it and the noise is gone. But now, I have a whistling sound coming from the engine.
Did you get rid of this problem. If you didn't, here I am gonna tell you something. Because the timing chain tensioner failure, probably your engine's timing valves got into some different gaps. Check your valves' gaps, probably they need adjustment.
You are great teacher!! One question....in the US most of the tensioner tiny retainer clips are released 45 degrees counterclockwise (Part Number: 13450-0D010). The tensioners you've featured on your channel release in the opposite direction; clockwise. Did someone rotate the tiny retainer clip 180 degrees or is that how they come from Toyota.
Thanks for comment dear Not important you return the Crankshaft 45 degree If you rotate even a little unclockwise and return clockwise so you hear some sound and continue rotet the Crankshaft As much as you want

Cool. Would you recommend replacing tensioner at 193k miles on 1ZZ-FE engine? Chain did seem a bit slack when changing valve cover gasket and there is a tiny 1 second rattle on cold start.

@@drdelirious8899 I checked it about 6 months ago, no leaks. The VVTi solenoid O-ring did have a tiny leak, so I replaced the solenoid/o-ring assembly.
Question ❓ I'm just trying to replace the gasket on the *timing chain tensioner!* (It has the only oil seepage I see on the whole entire engine) is it necessary to pull off the valve cover, and as an engine have to be top dead center?
Timing chain tensioner in VVTi engine always produces noise on cold engine startup for a few may be 5 secs and some times less than that even after some hot engine startups. Kindly comment

It is not necessary to remove the valve cover, but it is better to fit the crankshaft pulley at zero mark.
What is that "rattle" noise #1 @9:07 and high pitch noise at the end of #2 @9:14. Is that starter issues? Thanks
Vvti gear
Timing chain tensioner in VVTi engine always produces noise on cold engine startup for a few may be 5 secs and some times less than that even after some hot engine startups. Kindly comment
In this case, the VVTi gear or chain tensioner may be damaged
Same to all vvti engine with 300000 mileage and above
There’s any reason why did you remove the top engine cover? Is it necessary to remove?
Thanks for comment,Remove the valve cover simply because when the chain tension is bad, the small chain sleeper on top of it also breaks, to check it.
