I recently bought a 1988 Rx7 Turbo II and have had a mechanic tell me the corner seals on the enlgine have gone. The engine has only done 10K miles and the turbo even less (I have all the receipts from the work). So I am a little skeptical at his diagnosis (it took two months to find the problem). The symptoms were poor idle and wouldn't start when hot. Anyone know of a backyard guy who knows what he is doing?
 
Compression is about 100 in aech rotor housing but engine only 10K miles old. Current mechanic says dirty fuel caused it but it doesn't make sense. Says its the corner seals and the engine needs a rebuild. With an engine that has recently been rebuilt would you need to completely rebuild it again if in fact the corner seals had gone?
 
You may not need a complete rebuild but you might need all new seals and so you'd have the labor to take it all apart, install new seals and reassemble. If you're rebuild guy is good, he might be able to reuse some of the seals, not sure, but they may be assemble-once-then-discard type items.

Either way, new seals aren't too much money but the labor would be the killer. The seals on rotaries are the fragile parts. When they go, you don't have many options and they can go if you get dirt in the engine, but I'm not sure about it getting in through dirty fuel. Was the engine ever run with the air filter off or ram air or anything like that? Dirt can get in that way pretty easily if you're not careful. I got only one racing season on a 13B when I tried a ram air setup and think I got dirt in through the air filter (at least that what my engine builder said). Back in the 90s, there was a guy Carol Ashley, he went by the name A.J., who ran a shop on Long Island called Father & Sons Auto where he prepped a bunch of 2nd gen RX7s for racing. I'm not sure if this is the same shop as the used car dealership with that name but it could be. You might want to call them and ask for AJ and, if he's there, find out if he still works on RX7s. Otherwise, I don't know anyone else on LI but I sold my rotary several years ago.
