[Gmecm] Off topic - rear main seal packing

[David Allen]

  The rubber seal fit great, however I haven't run the engine yet.
 On this engine (being Mom's car) I'm not worried about a few HP.   The 
friction and heat in the engine are a concern; as well as the potential for 
clamping fibers of packing between the rear main cap and block, thus 
disturbing the clearances on the rear main bearings.
  My job is seasonal, tied to the farming seasons.  This time right now is 
"in season" and I haven't been home in 2 weeks to work on it!!
  Pictures of install are here:

  Later,
David
