this has truly been an education. i get it a little better now. i'll get off my *** and put my plexiglas rig back together and take a closer look. glad to see this thread hasn't filled up with all the bickering like it did on the other board.

Hello. I just took my engine apart after a slow miserable death of my last engine. :/
I ended up with 2 blown side seals, and 2 blown corner seals on the inside of the front rotor. The side seals were blown on the trailing side of the side seal, and the last surviving side seal from that rotor is beveled on the trailing side also.
--Side seal A and B broke off on the TRAILING ends.
--The corner seals between A-B, and C-A, were cracked.
The rear rotors inside sides side seals are also beveled on the trailing side. When I say beveled, I mean they look like this.
The front side of the intermediate plate's ports look like this.
and the rear side of the intermediate plate's ports look like this.
What would you consider the main cause for this? The intermediate iron got a street port. These are from a 13b-RE. If you need any more information, just ask. Everything else in the engine was perfectly fine. (all apex seals, housings, turbo, turbo housings, were all perfectly fine.)
If I could get your opinion Lynn, that would be great.
Thanks

plus something that all people porting engines from 1986 on up need to know. from 86 on up mazda changed to a thinner sideseal, this made the sideseals a weaker sideseal and easier to fall apart. to be continue.

But thankfully now others can learn from it and find other ways to destroy our engines!
Really looking forward to your continuation Judge Ito, this is a very informative thread by everyone, thanks for the contributions.
