[Vwdiesel] The importance to lining up oil pump gears with markings on ea...

  That kind of knocking CAN be caused by bad injector/s.  Will just 
found that out.  Oil pressure drop is usually from non replaced int 
shaft bearings.
  Not quite sure what you mean by lining up the gears.  You do need 
to always be sure the drive shaft slot and tab properly engage so that 
the oil pump will turn but I don't recall mesh/timing marks on the 
gears themselves.  Even so, it would continue to pump oil, just perhaps 
less efficiently and the pump might wear but the oil filter should catch 
the wear particles and so long as you don't drive it with no pressure, 
the mains should survive fine and you'd just need to replace the oil 
pump.
   Ahhh, just realized what the "mail" bearings are!  "L" typo for an "N".
 :-D
  Maybe it's just something with the oil pump AND a bad injector or 
two instead of bearings?  :-)
