Jeff,

It is lifter tap from the lifters bleeding down from sitting for a
while.  You could run the van more and it probably wouldn't happen but I
understand why you don't want to drive it in the winter.  It is a mere
annoyance at best.  Once you take it out for the spring and drive it
more it should not occur.  I would just not worry about it unless it
starts doing it every morning, then you might want to track down that
lifter and replace it.

Hope this helps,
Ken Wilford
