Really?  I didn't know any of us _knew_ what the failure mode was.  I 
assumed it was some spring inside wearing out, or a seal blowing.  Also, 
another lister was experimenting with turning the spring or spring
holder 
90 degrees or so, thereby tightening the spring and making the noise go 
away.

This is the first I've heard of the pump filling w/oil.  How long have 
we (the q-list) known about this?  Or have we?

If it's true, "You learn something new every day."
