I can see why you guys like the rotaries so much. I am pretty neutral on pistons vs. rotaries but my ported keg that I just got going sounded so cool. I almost forgot how rotaries hum and whirr over this last year of putting my project together and being stuck with my POS integra.



Even with stock exhaust it has kind of a barky tone because I got rid of the NA diffuser sleeves in favor of TII ones.



It's burning coolant so I have a pinched O ring in there that I need to fix. It'll be easy doing the tear down and reassembly compared to the first time because I got some serious wrench turning practice getting this far. https://www.nopistons.com/forums/pub...IR#>/smile.png

Oh yeah. I feel all bubbly inside now. Too bad the coolant was that way in the engine.

I cant wait to be able to afford my RX7 rebuild, i love my car so much.

nice! hopefully u can take care of that o ring

Thanks to a burst of abnormally virile motivation, I just got finished with a four hour slam session of engine removal and disassembly. And I fould out what went wrong: an O ring was ruptured because of its ill fitment and resultant pinching between housings, but not the O ring that I suspected. It was the one I stretched a little too far which made it a little too big for the groove. I thought it would have been one of the tight fitting ones which kept popping out during assembly. All of them were pretty tweaked. The ones that fit tightly had pinch marks on their inside edges, with the ruptured one showing pinch damage on both the inside and outside edges.



A note to anyone using these "Teflon encapsulated combustion O rings" from real world / rotary aviation or Atkins, make sure they fit perfectly in the grooves. You will probably have to stretch them a tad, but if you stretch too much, they eventually shrink back to their original size.



So anyhow, time for me to find some different inner O rings. Anyone know where to find the more conventional kind? Somewhere there was a thread where someone found out how to buy them from their source for like $8 apiece.
