Oil Cooler Mount Cracks - Replacement Follow Up...
      
      
      Dear Listers,
      
      First, let me say thanks to everyone that responded to my post regarding the
       oil cooler mount cracks.  Lots of great feedback; I really appreciate it.
      
      Rather than subject the Oil Cooler's mounts directly to the mounting screw's
       tension, I decided to craft some angle brackets that much more evenly
       distribute the load over the original mount.  I made a set for the front
       and back of the rear mount and a single top bracket for the front mount
       that would sandwich the Oil Cooler mount to the rear baffle.  I very
       carefully trimmed the tube spacers to exactly fit between the front and
       back brackets; much more precisely than the original installation.  The
       inside rear Oil Cooler mount got the requisite top and bottom notching to
       clear the engine mount and this time I hogged out a bit more to give even
       better clearance.  (A couple of people noted the scratches on the motor
       mount near these original notches; I believe these were from when I was
       filing the original oil cooler, I got a little over zealous and scrapped
       the power coat; I don't believe that there has been any incounters between
       the oil cooler and the mount due to engine shake.)  I also added a few more
       rivets on the flanges between the rear and left-rear baffle sheet metal
       pieces.  
      
      To absorb some of the engine vibration, crafted a "gasket" of sorts from the
       same rubber material the baffle seals are made of.  This really seem to
       nicely isolate the Oil Cooler from the baffle/engine.  
      
      Finally, I crafted a sweet stabilization strut from aluminum tube stock to
       form a brace from the engine to the top of the rear engine baffle.  This
       made a HUGE difference in the overall stiffness of the oil cooler and I'm
       hoping will be the final modification in solving this Oil Cooler cracking
       issue.
      
      Thanks again for all the feedback!
