NO!!! All rotaries have the sleeves in the exhaust. N/a's have the diffusers int he sleeve. I removed my sleeves. Look at the exhaust port pic again.

Sorry I didn't reply to your question a couple weeks ago . . it's probably too late but just in case, I could tell that the coolant seal was the problem because one was ruptured completely through the teflon, exposing the inner silicone O ring, which allowed coolant and exhaust gasses to change places and go where they weren't supposed to. Two others were mildly pinched, but not through, on the inside edge. None of the seals fit well when I first put them in.
I used the "teflon encapsulated (reusable) coolant O rings", available through Rotary Aviation, Atkins Rotary, and you might be surprised to learn that my replacements came from McMaster-Carr (mcmaster.com) and cost $45 shipped for 4. These directly sourced replacements fit MUCH more exactly than the ones Rotary Aviation sent me; I had to **** with the first set for a while to get them in (resulting in one jumping out during final assembly and getting pinched), while the Mcmaster ones fit _perfectly_ .
If anyone wants the Mcmaster part number, let me know. And they continue to seal perfectly as of three weeks and ~460 miles. My coolant tank level has been right where I left it when it was filled and had the initial bubbles burped out. And of course, no more fog machine!
It's having some idling issues but those are so easy to fix compared to a pinched coolant seal!
Is that what it turned out to be?
How did you finally find out?
Was it leak into both rotor housings or just one?
How did it look when you went back in there?
I ask because I think I may have a similiar problem.

Mazdaspeed7, how did you go about removing those sleeves? arent the press fit in?

Cool good looking out, but I think my problem maybe some epoxy that I used on one of the intake ports. I know everyone swares by the J.B. weld, but I'm starting to think thats what it is. Because everything else went in clean-no problems with any of my factory new seals-notha.. I'll find out this weekend when I take it back out. Sucks I hat taken out TII's.

You have to drill out the roll pin, or otherwise get it out, and then the sleeve comes out. If can only be done with the engine apart, and its a pain in the *** at that.

I wouldnt mind building motors for people, but Im not going to go out of my way to try to find customers. If someone comes to me asking me to build a motor, Ill do it. But Im not looking to make a living out of it.
I dont remember the specs of the exhaust port, but it does idle fine. Its not as smooth as a less ported motor, but this motor is idling at 600 rpm with the 6 ports closed, and the VDI wired on the high rpm setting. It holds a steady 600 rpm, but just not quite as smooth as a stock motor. The car is easily every bit a drivable as a stock car, possibly more.
