Dave,
 
  Cannot t= ell what to do concerning your TES "O" rings (I have them also) as I have no operational
experience with them= yet but considering the hours you have on your engine (And you have been <= /SPAN>
known to "Flog" it).= .......<:)... I would just go back with TES "O" rings in light= of the extra heat load
your Turbo adds to t= he engine...........
 
 Concerning the= corner seal rubber buttons it seems that they end up reverting back to car= bon and
lose all elasticity (particularity under h= igh heat) and become usel= ess for their original purpose which 
was to give slightly= increased compression at starter speeds...........I personally will use th= e solid
racing corner seals = available from Mazda and other sources.................IMHO

Subject: [FlyRotary] Where's the Buttons?

I just finished tearing down my engine.  I am doing a rebuild for= low compression on one of the faces (determined by a change in the force r= equired to pull the prop through on that face and a quiet 'ka-chunk'), and = some leaking of combustion gasses into coolant causing occasional loss of c= oolant if not checked before every flight.
 
Results of tear down.. 
Where are the rubber buttons?  There are no rubber buttons in any= of the corner seals.. not even a residue.  Do they usually disappear?= ?  I am pretty sure I recall them being there in the past, or am I mis= taken?  I used the strip that comes in Tracy's gasket kit.
 
I found a side seal that was stuck at one end.  quick clean shoul= d fix it.
 
Coolant issue:  Not sure I am happy with the TES 0-rings.  Y= es, they seem to have been very resistent to the heat.  In general the= y are in excellent condition.  Except, they have very little elasticit= y and have moulded to the shape of the chanel.  In the hot area, they = no longer extend above the top of the chanel and are more or less flush wit= h the top.  It seems that in this area they would be exerting minimal = sealing pressure there.  I am thinking about going back to the stock.&= nbsp; Anyone else have a similar experience or heard of this problem?
 
Otherwise the engine is in OK shape.  No evidence of overhea= ting.  There are quite of bit of chatter marks on the rotor housi= ngs, the rotor bearings seems pretty well worn but probably re-usable. = ;
