Broken springs and damaged piston-block in a high pressure oil swashplate pump from an early 6.0L Powerstroke.

The springs broke and damaged the surface of the piston-block. This prevented a positive seal and created low ICP. During the air test a leak could be heard in the oil filter stand pipe coming for the HP oil reservoir.
