No, didn't take it out yet. Still waiting for some prior experience from the board. The hard piping has the typical frozen fittings like the tranny filler tube fitting except smaller. I couldn't break them loose in that little space under the intake. The best way to get to the breather box may be to just remove the flange fitting at the intake and pry the gizmo over a 1/2 inch. The connection at the exhaust is another almost un-viewable pipe fitting. I would think that the two bolt flange fitting on the manifold has a gasket.
