[DML] Re: oil leak in valley-o-death (was first week of ownership blues (crankshaft seal))

Sorry to hear about your oil leak problem.

  From what you describe and the amount of oil you have pouring out of 
the valley area, you may have a hole into the pressurized oil passage 
to the head.  I might be wrong, and someone with more knowledge of the 
PRV engine might have more insight...
Here's what I gather:
  1. You have a hole in the block from the exterior into an oil area.  
That might be only return oil pooling up and spilling out, but from the 
amount of oil and the rapid failure once the leak started, I would 
guess that you've struck an oil feed channel.
  2. Since you may need to replace the whole block anyway, you might as 
well try anything to reair the hole.  However, if the hole is indeed 
into the oil feed passage for the cylinder head you risk damaging the 
cam and valve train, also possibly damaging the head if oil flow is 
lost to that area.  Then you go from needing a block to needing a block 
and a head, and a cam, and followers, etc...
  3. Since you may have hit an oil feed channel, the oil leak you are 
attempting to fix is going to be under pressure.  Possibly 80psi or 
higher.  Anything that you fix it with will need to be solid and 
secure.  The first warning of a failure of the repair might be the oil 
pressure dropping!  Of course all the drivers behind you would have 
known about your leak for quite some time :P  James Bond anyone?
  I may be off base on all this since I don't know exactly where the 
leak is, someone more experienced may have better insight.
