X-Mozilla-Keys:                                                                                 

To interject my 2 cents into this discussion, this is how I install the inner
and outer O-rings:

The O-rings, as they are packaged in Mazda's gasket, are taped to a cardboard
sheet (the inner combustion O-rings) and looped into a small group (outer
black rubber O-rings).
The inner silicon O-ring is installed with it's seam at approximately 1:30,
this is just above the intake port. The orange sides face vertically: one
against the bottom of the O-ring groove and the other against the rotor
housing.  The Teflon sides will be facing the side walls of the O-ring
groove. I place the O-rings in the grooves as they are oriented on the piece
of cardboard. In other words, I do not flip them inside out. After tearing
down approximately 35 to 40 core engines, I have never found one of the metal
protector strips in an 86-95 engine. I have seen them in earlier models but
they were never present in the late model engines that I have taken apart.
Beware: The Haynes manual engine section is just an updated article from
their older generation 1 book. Some of the pictures and text are for the
earlier engines.

The outer rubber O-ring does not have a seam and therefore is simply placed
in the groove with the black sides facing vertically. The O-rings supplied in
my gasket sets have white paint on both sides so there isn't any way to
differentiate which horizontal side faces the water and which faces out.
Hope this helps,
