That's a bunch of damage...
Looks like the pump cavitated at one time causing extreme friction and heat to the valve plate...
The valve plate warped and made contact with the cylinder..there is usually a layer of fluid between them..even under pressure..
A piece of the valve plate wore into the cylinder block...look closely at the slits in the plate..the hot pressurized fluid did the rest..
1200 psi is normal between the valve plate and the cylinder around 300 degrees..
Any leaks between them will act like a mini pressure washer ...blasting away more and more metal until it fails..
The metal residue in the hydrotank is all that's left of the missing metal...
