Paul,
The headers and intake tubes should be welded up in a couple of
weeks, so now I am looking for all of the pieces to rebuild the
engine. Lynn mentioned solid corner seals without rubber plugs.
They tend to last longer.  I looked at Mazdatrix and they have one
 for 3mm seals.  Would it be worth the trouble to go to 3mm seals?
 They also have a differnt corner seal sprig that looks like a bent
up flat washer.  Any good words or are these parts all hype?

Thanks

I do not know very much about the subject of corner seals.
I do know the RX8 engine uses DLC Diamond Like Coating on the
corner seals. That is about it. I could be forgetting something
that was said years ago.

I would not do the 3 mm unless your apex seal slots are worn.
Do they pass the vertical apex seal wiggle test? If so I would
leave them alone. I ran across a technical letter recently in
my paper files by Dr. Francisco Iannette. I'll OCR it some day
and publish it. According Francisco silicon nitride apex seals
do not wear the slots I was amazed to find out. We are now
getting close to infinite life for the rotary :)

Check Hurley Engineering website. Corner seals with 3 springs behind instead
of the Mazda springs. 2mm and 3mm available.
