Update: It's not about \psclip, it happens with \pscustom only:

\documentclass{article}
\usepackage{pstricks}
\usepackage{pst-coil}
\begin{document}
\begin{pspicture}[showgrid=true](0,-4)(8,4)
  \pscustom[linewidth=1pt]{%
    \psline(0, 2)(4,4)%
    \pssin(4,4)(8,4)%
    \psline(8,4)(8,-4)%
  \closepath}%
\end{pspicture}
\end{document}
