Engine Seized up. kinda. Would turn but hard. Found bent rod.

The engine just stopped running and would not turn over for some reason. I removed the head cover, breaking a head off a bolt in the process, and saw the rod was bent like an s shape. Ordered all new parts, and installation was a breeze.
