87 4kq coolant reservoir cap bad?

[Cade Carvell]

Hello,
  The other day I had accidetaly put in to much coolant in the resevoir
tank (expansion tank), which later caused the famous hood raised and
coolant vapor spewing out.
  So, after car cooled down, got it home, ad put in more coolant, and
was careful to watch the lines for level....
  Now, when the engine is warmed up I can hear a hissing coming from the
cap on the resevoir tank, meaning that it is not sealing properly, or is
realising pressure to quickly.
  Anyway, I am going to need to replace it, does anyone know of a place
that would sell this new?  I can find it used around here...But I would
rather spend more and get it new.

Thanks,
