I must say this function seems rather obscure to me, but how about:

function {
  (-(x+3)/7+abs((x+3)/16))^2  
  + (y-abs(y/4))^2 
  + (z/3)^2
  - 1
}

I personally would use a combination of two ellipsoid functions rather
than this.

something like:

#declare fn_ellipsoid=
function { 
  sqrt(x^2 + y^2 + z^2)-1
}

isosurface{ 
  function {  
    (fn_ellipsoid(x*1.0, y, z)) |
    (fn_ellipsoid(x*0.2, y, z) & (-x))
  }
...
