I just wanted to let you know that you can replace the tensioner without removing the valve cover. You do not need to release the latch on the tensioner with a screwdriver after it is installed. If the tensioner is compressed all the way the latch will release itself. Engage the latch and install the tensioner, then you can use a socket on the crankshaft to rotate it slowly in a counter-clockwise direction. This will take the slack out of the timing chain without moving the cam sprocket. As the chain tightens it will depress the tensioner completely and release the latch. You can actually hear it click.
Awesome video, but I found somewhere that you can turn the crankshaft counter-clockwise until you hear the click of the latch releasing, and then turn it clockwise to make sure the tensioner released. It saves you the trouble of opening up your engine!
Peter, To release the little retaining clip on the tensioner all you have to do is turn the engine over backwards with a wrench on the crank. It will release the clip by turning it about 180 degrees and you don't have to try to stick a screwdriver in through the valve cover.
Great video. Very informative. My Toyota dealer told me $600 to fix an oil leak from my timing chain cover. I think it might just be the o-ring on the tensioner.
You just turn the engine backwards a bit so it tensions the the slack side of the chain. It will push the plunger releasing the latch, the tensioner will pop out automatically 👍
btw..there is an "Inspection hole" on the front cover Crankcase Chain Cover, that is precisely meant to "FLIP" that Lock open that holds the spring in for installation..(it should be a rubber plug)
inside the tensioner is a small spring and valve! that lets oil pass through to help to tension the timing chain! the small hole in the valve can become blocked with sealant and will cause a noise from the timing chain as the engine warms up!

You have to turn the engine manually clockwise after inserting the tensioner Wait for the click of the tensioner before staring the engine

This video just saved me. I am putting together a 1zz Toyota motor and needed this information to finish. Thank you, Peter! :)

Excellent video Peter, Keep up the good work.
Excellent video, very detailed. Thank you!
You are very good at describing all your projects! I have watched several. Thanks for your thouroghness and patience.

Hi Peter, Thank you for your videos

Obrigado, ajudou muito
Thank you so much for the information
you are the best car docter👍keep up doing the good work

Bolshoe spaseeba, Peter for your helpful video :-)
Good series of videos very detailed.
What if you break one of the bolts? By getting it too tight? Can you fix it? Since it’s attached to the engine.
