You know, those who have been here a long time will know that I've long
suspected the chain tensioner for this problem.  This just really makes me
feel that much stronger about it.  I think the tensioner must leak down
somehow.

Now that this happened right after a cam change makes me believe it even
more.  I have no causal data to back it up.  Call it a hunch.  A feel.  But
I'm sticking with it.
