2007 SE Timing Chain at 260K Miles

[Bluesky 07]

I found a video describing one way of evaluating the timing chain and decided to have a look. I pulled the inspection plate (front passenger side of the engine) and took a pic. Here's a comparison of my tensioner (left) vs. a screenshot of one where the chain is stretched. The less tensioner exposed, the better.

Here's a view using an endoscopic camera inserted in the oil filler neck.

Everything looks pretty good to me but I'd appreciate opinions from people who know more about this. TIA.

Not a timing chain expert, but if the tensioner rod "extension" is a good measure, and it seems that it would be, yours looks very good in comparison to the other one.
