Dan, thanks for the suggestion.  I realized after I had sent it that I
wasn't explicit enough.  The smell only occurs if the automatic climate
control is heating (and it does not occur all of the time, typically if the
engine is hot--having been run hard or for awhile).  If it is using A/C, it
doesn't occur... Maybe it is just because the sensation of freon nullifies
the smell.  Additionally, I don't notice it when the climate system is
off. It is almost a smell of burning oil, hydrolic fluid, or antifreeze.
I'm not good at determining the smell.

One person suggested checking the Valve Cover seal to see if it begins to
leak oil.  I recently had the seals replaced (hoping that the side benefit
would be fixing the smell), but, I can check that as well...
