[Vwdiesel] Engine knock - TD motor

  Wow, great deal!
  Sounds like you have a couple problems.  The pressurizing is from a blown
 head gasket.  The knock could be from a rod bearing or injector.  Rods 
don't usually get bent in these engines unless someone hydraulic'd the 
cylinder and even then...  The knock could be from water getting to the 
tip of the injector and damaging it so it could be related but still two 
problems.  I'd run the injectors while in the process of doing the head 
gasket.
