If I get her running, my plan is to keep her. She's a bit of a beater, but she was my first. She doesn't have A/C, but the heater works awesome so I'll use her to save some miles on my '09 Tacoma, especially during the cooler months.
You asked, I delivered .... more pics below.
On the 3rd picture, I've noted a couple more area's of damage on the TC cover. I can only assume that as the chain was rounding the crank gear, it caused that damage as well. The red box indicates an area where a good chunk of metal was very obviously worn down. It's hard to see in the pic, but the green box shows an area with the same kind of tracks as the side of the cover has.
Additionally, there is evidence that the chain was making contact with the head starting at the point the distributor bolts in at. They don't seem that bad to me, but I'm definitely keeping it in the back of my mind as I put this thing back together.
Also, in the 4th pic, you can see the tensioner in action. I have no basis for comparison, but it certainly seems that it's taking up a lot of slack. Additionally, as the chain is rotated in place, the slack seems to transfer back and forth between the driver and the passenger side of the truck, which seemed kind of odd to me. Does that sound normal?
