Wow, thats a champ engine. Your posting in the 2nd gen section, your car is a first generation rx7. ATF is bad, just use marval mystery oil as a substitue.

Mazda zoon cleaner will be awsome if you can run that. Not much you can do on a low compression engine. Hope it keeps running for you.

Your rotor housings can in fact be worn, as well as your seals on the rotors themselves. Keep reading and searching around and read the FAQ's, lots of information on here regarding all these topics.
