You didn't cover rotating the crank a few degrees backwards to release the tensioner. Very important.

[zombitroid]

Yeah, I agree you need to emphasize releasing the tensioner Brian. Extremely important! Or at least touch on how to do it

[mikalcobbs]

Yes you can do this yourself, just make sure it’s the tensioner gasket and not the timing cover. You can actually do it with a quarter inch ratchet without jacking the vehicle up if you reach over the back of the valve cover. I use a quarter inch ratchet with a deep well magnetic 10mm socket. After reinstalling make sure to turn the crank clockwise by hand until you hear three clicks telling you the tensioner deployed. If you just stick it in and crank the car up it can possibly jump time.

I bought my 2000 Corolla which has 1ZZ-FE engine back in 2016, and it had this pretty much the same timing chain tensioner. It keeps leaking, and the dip stick went from high to low in about 2k miles. I took it to few repair shops and none of them told me that I need that gasket until recently. Once the gasket was put in, the dip stick drop about 1/3 between high and low after 2k miles.


This is one of the most common cause of oil consumption which isn't really consumption, but leakage. So much talk about 8th gen Corolla with 1ZZ-FE engine burning oil, and I think that's just a joke. Not much people really know what's wrong.


Once the engine leak enough oil, the rest of the oil inside the engine will just get worked harder, so they turn black faster. If the owner doesn't pay attention to it which most owners don't, the engine will get gunked up oil fast. That will make it looks like burning oil, but it actually is not.

Great repair! I've done this exact repair on my 2002 Celica and 2003 Pontiac Vibe. One additional step upon installing the tensioner I included was to manually rotate the engine clockwise to release the tensioner prior to start up. I normally did this by rotating the alternator/serpentine belt. I have not seen a 1ZZ/2ZZ that did not have this leak.

Thanks Brian and Scotty K for your great videos!

I had no idea this fix was so easy.. tensioner on my girlfriends car has been leaking like a cut siev and I thought it was the cover.. already on the phone to Toyota ordering a new tensioner!! Thank you!!

[hevosmies]

Thank you for this video because it was very informative. I bought new gasket from dealer for 7 dollars and replaced it today so i hope it solves my leak issue on my 2007 corolla

[vadneysean]

99 corolla i just bought and noticed alot of oil on that side. Thought it might be oil pan but too much oil above pan and on smog pump. Gonna check this first so thanks for the tip.

[AndrewAlvarez-pyzz]

Wow! What a fantastic video. Thank you. I am going to begin diagnosing the leak on my girlfriend's Toyota Corolla this weekend. I will start here. Also, thank you to the viewer comments for adding additional feedback.

[callmebackfriday]

After watching this video, then I check my 2009 Toyota Corolla, and yes, I have oil and dirt around that area and I think I have a small leaks. I will monitor it. Thanks for the video.

[DylanRabier]

I didn't see how to release the tensioner after installing it back. 😁 Good tip on the sealant. They do leak all the time.

[nathanrandall]

I’ve noticed some models have a O ring an a gasket this one doesn’t have the o ring.

[Cypherus]

My 2002 Celica GT with the 1ZZ has been seeping oil from the timing chain tensioner for 10 years, and still no problems. Just make sure you change your oil, but it is not a 'do or die' issue.

Brian you vids are brilliant, you are my go to media / youtube mechnic. Your vids have helped me keep my old 2001 Corolla going strong. Please do a vid, on the notorious Corolla 1.8 liter valve seals replacement if you haven't already done so, or a link to a good video showing valve seal replacement for the 2001 Toyota Corolla s....Thanks, Peace P.S. I was quoted $500+ for complete remanufactured head with all new seals, from local chain auto parts retailer, I think I'll save my money and replace valve seals myself :). Crazyhorse.

My girlfriend has a cricut maker! I never thought to do this. Now how to figure out how to make it an SVG... wow, the possibilities this unlocks! Great idea, thanks!

Do you used the dye to find the oil leak I got a 11 corolla with a leak around timing cove

[pistonring]

I did this on my corolla 1998 and my son's corolla 2002. From time to time, oil leaks return. Tired fixing them. Hope those who did this made it a success.

[klyetry]

Not saying this is the correct way, but I reset (unhooked) the tensioner after reinstalling it by unplugging all 4 coil pack connections via the plastic wire harnesses and started the car. Obviously it just turned over the engine without firing. Then I reconnected coil pack wire harnesses and started car up like normal. This will likely give you a check engine light though.

[williamstrasser]

911 big mistake in this video you must turn the engine counter clock wise to release the tensioner spring
You have to or it won’t engage !!!! Watch other videos
