Need help finding a thread

Last weekend I found a thread that had several pictures of various member's timing-chain tensioners as viewed through that little plate.
The thread was a guy who was tracking down a leak, but there was a discussion about (with pictures) of the tensioner and when its been extended to its limit.

I've been looking for a half hour, I can't seem to find it. Any help pointing me to that thread again?
I want to see how far the tensioner will extend. Or how far it'll go. Mine is showing 4 of those little rings on it.

 

Maybe this one

No this one had actual photographs and there was a discussion about those rings that appear each time it comes out a notch.
One fella had picture of his and it was way out and he said it was fine. I wanted to see that pic and compare it to what I'm looking at.

 

Is this it?

Yeah that's it. Thank you!
Not sure why search wouldn't find it for me, unless its the hyphens in the title.
