Since piston #4 is junk, I must replace it but I am not sure about the rod. It looks good and didn't get bend, however there is some binding when I try to move the connecting rod with the piston attached to it. I've soaked it in oil, which helped a bit but not much.

I also noticed, that the wrist pin moves which is not a good sign. What do you guys think, could I just replace the piston in hopes it's the piston causing the binding or do I have to get a new rod? I've already sourced a piston with 1.2mmx1.5mmx3.0mm grooves with rings,bearings and a wrist pin for a good price.

Check out the pictures.
