Timing chain question

Hello again. I did an inspection on my timing chain. Just how stretched the chain tensioner is. I watched a video and one guy showed his timing chain is fully stretched and needs replacing. Could you take a look at these pictures and let me know where do I stand? It doesn't look as bad as the one in the video but still looks stretched. Thanks for any info! I have 2011 Taco with 322k kms

 

Doesn’t look too bad to me. It’s a got a lot length.
Yours looks “normal” to me.

 

This one is stretched. Enough that it threw codes.

 

Thats got to be 3/8"+ more than the op's.

What where the codes?
Is there a measurement that is considered unsafe stretch?
Have you ever heard of a plunger popping out with too much stretch?

 

Looks like neglectful OCI practices causing sludge which will increase stretch.

 

Cam/Crank correlation codes.
I never seen one pop out. Not sure it's even possible the way it's built.

@Bishop84 has much more experience than I do.
He's a tech at Toyota, if one has popped out, I'd say he's seen it.

 

Good visual.

 

Ya I wouldnt even think twice about this chain, its fine. Usually stretched chains show 50% tarnish.

Also you will have codes for stretched chain.

 

Off the top, do you know these codes?

 

P0012 specifically but it can be P0011, on here we see guys cleaning VVTI screens successfully, but where I am we change the chains out depending on mileage and VVTI test.
