I just bought a nice 7060 maroon belly (I will post pics later).  I had to start it up and move it yesterday.  The coolant heater didn't work, so I had to use a bit of pocket choke.  It hammered hard for a bit and then smoothed out.  I noticed the oil pressure guage that it has was showing a few pounds less than what it was when I brought it home.  After shutting it down, I noticed a pinhole in the side of the oil cooler, and some oil dribbling out of the hole.  I am sure that it wasn`t there before.  What could have caused this, and what is the fix.

Pin hole is there for a reason. If oil or antifreeze gets past either oring it will come out the hole.
  The fix is to remove the cooler and replace the orings.  MACK

Yea, thats the weep hole.  Sometimes will seep in cool weather, might go away when eng is warm and might stay away during summertime.   Keep an eye on it if it doest leak to badly.
