2005 TOYOTA COROLLA - COMMON OIL LEAK - TIMING CHAIN TENSIONER O-RING REPLACEMENT - DIY

[@duffman6675]

Best explanation I have seen of releasing the hook and setting the plunger with the diagram from the manual. This is about video number 8 I have seen. I think what happens is that rotating the engine backwards, CCW, makes the tensioner side of the chain tight, pressing on the plunger, releasing the hook. Rotating in the normal direction, CW, makes the tensioner side of the chain loose again, allowing the plunger to mostly extend. Then when the engine is running, oil pressure extends the plunger a little more, and takes up wear too.

[@keithreed3862]

Thanks for showing this repair! Really easy to do... HOWEVER, my tensioner stopped working after I removed it. When I pushed it down, it initially provided resistance and tried to go back up (as it should). But then it stopped and no longer provided any tension. It seems like it jammed because it wouldn't go further up or down. I bought a new tensioner the next day which I installed and it worked perfectly. I chalk it up as a really old part (my Matrix is 2004) that was likely the original and failed after it was removed. Just something for others to keep in mind...

[@nessgabe1050]

Buy a new TENSIONER

[@achmadrezafahlevi4860]

I think because the tensioner works with the oil pressure, if you compress it the oil will gone and the tensioner loss it's pressure, maybe you old part was still in good condition

[@johnmcminn9455]

K.R. .was the engine making a slight rattle, up to the point of changing the tensioner?

[@MARCELOOLIVEIRA-lg2gv]

But corollas VIN # beginning letter J is from Japan ….much better not leaking!

[@renan8486]

Great information. I have done my 2010 Corolla. I would add that a replacement of the gasket for the tensioner is needed part 13540C

[@JoDo777]

Thanks.

[@chrisnielsen3562]

I allways use a little grease on O -ring before installing on tensioner and a little silicone on base if no gasket is used .

[@ricklebrayd]

This is quite a good video.I have seen some other ones that show that a little sealant is put on the bottom of the plate there around the contact on the ends.Just curious why you didn't do that.Thanks for sharing the video.

[@MarzNet256]

There are two types used. One has the o-ring and the other has a flat gasket to seal. The sealant is used on the gasket only.

[@zmarssojourner7435]

Hi Ty u for the vid! There is a vid by a YT channel called TRQ. There, before they start this entire repair, they ask us to release the pressure on the tensioner by turning the harmonic balancer and the crank bolt. Why did you not perform that step? Ty

[@jordan6556]

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 in the beginning?this is another youtuber told me to turn clockwise to release hook.i dont feel to open engine cover and i dont have camera,and you need to buy new engine cover gasket too and extra.

[@Cranked2Crunked26]

Should the engine be turned to tdc before removing the damper? I was told by turning to TDC, this helps to avoid jumping a tooth.

[@ipaporod]

Mine is also leaking (Corolla 2013 S) but since is leaking a very diminutive/insignificant amount of oil I decided to wait until the timing belt change is due and my mechanic will do it as part of the job anyways!.

[@mikelauderdale9450]

Great video, clear and to the point.

[@happycat0411]

If you cannot get a new tensioner o ring you can re-use the old tensioner o ring. To reuse the old tensioner, first clean the old tensioner that you have. After the tensioner is dry, the groove where the tensioner o ring sits wrap the groove with some Teflon tape and then reinstall the original o ring seal back onto the tensioner o ring grove. The Teflon tape should give the o ring enough o ring pressure to prevent the old tensioner o ring from leaking again. It's better to buy a new tensioner o ring but if the o ring isn't available you can improvise and re-use the old o ring if you have to.

[@alwaysforeigner]

Would it be a good idea to use an extra seal? silicon or rubber? On the base?

[@DhalNaath]

yes

[@ynonser5804]

great video! did it solve the oil consumption problem? these engines are notorious for oil burning, usually is the piston rings but i guess i'll give it a shot😎

[@AmeriFanPicker]

So you went with clockwise? Can’t seem to get a straight answer lol. Have a 2zz so I have to loosen and move the belt tensioner out of the way s bit apparently.

[@markmarxman584]

Does the motor have to be at top dead center, or can you just remove the tensioner at any point

[@davidpouliot]

Perhaps its been covered but missed by me, do you need to completely drain the oil prior to removing the timing chain tensioner?

[@DantheFixitMan]

Hi David, No need to drain the oil. It may drip a little when you take out the tensioner, but most of the oil will be down in the pan. Thanks for watching! -Dan the Fix it Man

[@jacintogonzalez7146]

I installed new valve cover gasket new t c tensioner and I still have a leak in the tensioner area it's leaking on my power steering pump . any ideas?? I think maybe the tensioner o ring did not hold the leak maybe. But I'm not sure if the leak is from there

[@DhalNaath]

crank seal

[@calbob750]

If you were looking under the car from the front where would you see the oil leak. It doesn’t appear to be the oil pan, but a surface behind it.

[@DantheFixitMan]

The tensioner is on the back or up against the back of the engine area. It may be this that is causing oil to drip down below. It could also be a leaking valve cover gasket dripping oil down the back. You may need to put the car on a lift and inspect it from below. Best of luck to you. -Dan the Fix it Man

My mechanic applied some gasket maker on the new O ring which came with my new tensioner. I think he did a big mistake

[@KrazyKramer]

He shouldn't have done that. Find a new mechanic

[@JohnSmith-pl2bk]

Unless he added the gasket maker to the flat steel base part with the bolt holes in it.. basically forming an extra seal there..... which some mechanics do so when the O ring gives up again (same number of years later as your engine did with the OEM O ring).. well all the oil will stay inside the engine as it can't leak out past the gasket formed by the gasket maker. Smart eh?

[@steveambrose2349]

In my case I had two Toyota dealerships in Utah swindle me out of mega bucks telling me too that the leak was due to a timing chain tensioner o ring. After installation the leaks leak continued. Seems it wasn’t an o ring failure but the timing chain cover gasket that was the real cause.of the leak. What a waste of money. Premeditated evil on the part of these service departments. I’ll never go back to a Toyota dealership again.

[@investedcrypto9210]

how much did it cost to replace the timing cover gasket

[@DougHinVA]

it may be simple to do IF you know where it is and how to do it, but for most owners it is a job for a mechanic to do correctly. The video cannot even get a clear photo of it!

[@silverstonemalik440]

How much does it cost if change socket from mechanic

[@menguardingtheirownwallets6791]

I had a slight leak in the same area, but instead of taking the tensioner off to replace the O-ring, I simply added a 236 ml bottle of 'AT-205 RE-SEAL' to the oil, and after just 1,000 km of using this stuff, the oil leak has stopped. I read this about the product: ("Engine seals harden and shrink from the plasticizers being removed over time. This professional strength synthetic stop leak revitalizes these worn seals and gaskets to restore them to like-new performance.") Well, it seems to work, and for only $20.

[@jukeboxwiz315]

Is this process going to drain the oil in the car?

[@jonjont320]

I have the 2ZZ engine. Do you have a video on loosening the serpentine belt ?

[@chocolate_squiggle]

From the 7:00 minute mark, look immediately to the left of the power steering cap - there in the background you can see a hex bolt head peeking through under some hoses . I can't see if that's exactly the right one but in that area is two similar looking bolt heads on the serpentine belt tensioner. One is an actual bolt, and one just looks like a bolt head but is actually a part of the casting. You need to get a socket or spanner (wrench) onto the fake cast nut, with the handle pointing upwards, and gently pull it towards the front of the car. Personally I could fit a socket on but had no room with or without extensions to attach a handle, due to some hard (air-con?) lines. So I had to use a spanner. But it requires a lot of force and so if you have access to an 'extra long' spanner or serpentine belt tool that's great - I used the slightly dubious 'double wrench' method to extend my spanner to get extra torque. A cheater pipe may be safer if you have one. Once you pull the spanner towards the front of the car the belt loosens and you can just slip it off the alternator. Takes seconds when you know how. Take a photo or draw a diagram of your belt routing first. I got cocky my second time and got myself confused lol. Good luck. Sorry just realised mine is 1ZZ-FE engine.

This honestly sounds like a clogged cat. A loose tensioner would be indicative of chain rattle...This comment is 6 months later, so did you fix it yet?

[@williamferrante3855]

@@ethan.... no I have not fixed it yet no codes or anything, I’ve tried everything

[@ethan....]

To verify a clogged cat condition, get an OBD II scanner and look at the O2 bank 1 upstream sensor compared to the O2 bank 1 downstream sensor voltage. Upstream should be going from lean to rich or .1 volts to .9 volts regularly. The downstream sensor should hover around .155 volts steadily. If you see both O2 sensors have similar wave forms identical to each other - you have a bad cat. (this is because the cat is not burning the excess fuel) Also, to verify a clogged cat condition, remove the upstream sensor and see if you can rev the engine. If you can, then this 100% verifies there is a clogged exhaust at the cat. make sure you put a heat shroud to deflect the hot gasses from the o2 sensor port do not burn anything.
