Timing chain cover

 
The rear cover of the oil pump assembly is visible in the bottom of the timing chain cover.
  

Oil pump

  
A closer view shows the oil pump cover & assembly.  Oil pump end-to-end clearance measured within factory tolerances.
  

Oil pump internals

  
After removing the oil pump cover, the pump rotors are visible.  Oil pump body clearance and rotor tip clearance measured within factory tolerances as well.
  

Oil pump internals

  
The sides of the pump rotors had some pretty deep scratches.
  

Oil pump internasl

  
The outside of the outer rotor was pretty scratched up also.
  

Oil pump rotor

  
The inside of the inner rotor shows some gouging.  It definitely looks like some metal pieces went through here.
  
Bottom view of head   
A bottom view of the head removed from the block.  The head bolts sure are tight, and a long breaker bar was required.  The valves and combustion chambers were pretty black and had a lot of deposits on them.
  
Valves   
The valves & combustion chamber in cylinder #4.  NOTE: Ignore the shiny layer of oil - the motor has been upside-down & right-side up repeatedly on the stand with oil leaking everywhere.
  
Exhaust valve #4
