The timing chain tensioner oil leak is very widespread across all vehicles with the Toyota 1zz-fe and 2zz-ge 1.8-liter engines. Affected vehicles include Corolla , Fielder, Runx (Japan), Altis (Asia), Spacio, Verso, Allion, Premio, Vista, Ardeo, WiLL VS, Caldina, RAV4, Prizm, Vibe, Celica, Matrix, Avensis, Opa, Isis, Wish, Lotus Elise.
On aged vehicles the timing cover undergoes some very small dimensional change over time. A new original o-ring for the tensioner is not able to provide and adequate seal.
A slightly thicker o-ring is needed to stop the oil leak. The new and improved o-ring is shown in this video.

TRANSCRIPT
this is a 2005 Toyota Matrix with a 1zzfe 1.8 liter engine this is the timing chain tensioner that inserts into the timing cover and it keeps tension on the chain to prevent it from skipping the problem that I'm seeing on almost all of these engines nowadays is that this o-ring that is designed to prevent oil from leaking out of the timing cover is not doing its job so you might think I'll just order a new o-ring from Toyota and install it in problem solved right wrong well we're finding on most of these engines is as they age the dimensions of the timing cover change a little bit in this o-ring no longer provides a seal you can watch any of my videos on how to remove this tensioner and how to reinstall it but in this video I'm going to give you a foolproof method of preventing the tensioner from leaking again [Music] so the answer in order to prevent the O-ring from leaking again is you cannot use the original o-ring you have to use a different o-ring with a little bit more thickness and here I have a whole bag of these aftermarket O-rings that meet the requirement of sealing the tensioner
you can buy these on Amazon and I'm gonna provide you with a link to purchase these O-rings directly here is the old o-ring and the new o-ring side by side you don't see much of a difference but the main thing you should know is that the original o-ring is a metric o-ring and the replacement o-ring that seals a little bit better is a SAE o-ring here's the tensioner with the new o-ring and the latch is caulked and it's ready to insert back into the timing cover watch one of my other videos on how to release the latch the tension over the new o-ring is back in and this solution that I've just shown you has worked every time that I've tried it so I hope it works for you too hope you've enjoyed this video thank you for watching
