5.9 mag tear down with pics...no tensioner?

I paid 100$ .. the guy wanted 650 on CL but I told him I would pass because it was a pig in a poke and gave him my number.
He called me 6 months later .

As for the guide wearing. Wouldn't any shavings be picked up by the oil filter ?
And if it takes as little as 20k miles to eat it away the particles would have to be very minute I would think.
