Paul,
    Do you recall the dash number or part number for the Teflon O rings

from

McMaster Carr for the inner coolant seals (or their dimensions).

Thanks

No I don't Ed. The ones I bought were from an expensive source and
they did not use the standard o-ring numbering system.

... BIG SNIP

IMHO these high temp Teflon encapsulated silicone O-rings are a major
improvement in the durability and toughness of the rotary engine.

Thanks Paul,

    I'll take those measurements and see what I come up with.  I may just
order one to see if it fits.  When I took the six port apart (with the stuck
seal - had to finally punch it out with a punch and hammer), the Teflon "O"
rings were just like new.  I laid a straight edge across the housing face
and they still had enough resilience that you could slip a 0.01 " feeler
gauge under it.  I considered reusing them (Hayes claims the racing crowd
does), but just can bring myself to put together the 91 Turbo II with "used"
coolant rings.
