...The wrist pin clip looked like it was also in wrong, in school (if I remember correctly) the opening in the ring clip is supposed to be riding in the top or bottom of that piston, not the side. (Perhaps they move over time?)
Good catch.
Yes, our oldschool shop practice was to install clips with the opening up or down. Prevents their potential closing and ejection at high rpms.
Your homework.
