• I run a recent professionally rebuilt AAZ which showed no leak when I ran it first  from the machine shop last year. I have hardly used it, maybe 2 hours altogether. Now there is an oil leak which seems to originate in the block to head interface on the vacuum pump side. My question: should I check the torque of the cylinder head 10 bolts? Do these normally have to be retorqued after a rebuild?
  
  Thanks.

• Normally you don't need to retorque with the metal HG. You can't really check the torque because it's x ft/lbs + 1/2 a turn. It won't hurt to check to make sure they aren't lose though.
  
  Check to make sure it's not a rotted turbo oil feed line or something similar
