Hi Will.
Good job on numbering the cylinders and components.

The "wear" flat on the pump plunger is intentional. They should all have that. It allows a constant bleed of oil to lube up the cam gear area.

The engine looks pretty good inside, if you are confident you have found the source of the metal, is it just a case of reassembly?

Will you use some self locking nuts?
