Neat!  What a good tool this internet and digital/cyber stuff is.  But
that sound stumps me.

  I would not say rod knock or main bearings...Doesn't sound like many
motors I have had, those running on their last legs that have later grenaded
a motor...The sound is too intermittant for that, in my not so informed
opinion.  It could easily be something with the intermediate shaft or the
dist drive..
  For peace of mind, cut open your oil filter and check for metal
flakes...that will tell you if you have bearing problems.
