Hello!
 

Hello everyone, been lurking these forms read some topics and decided to sign up! I love Mazda cars (prob cause I fell in love with the MX6 my dad once owned), and have a growing interest in the RX7. Have been wanting to get a car for a while (money burns in my pocket T_T) and originally wanted to get an MX6, but the more I read about the RX7, the more I want it, well the FC model (looks the best)!

I have just one question, really noob one too, but in reading about the Wankel engine, and peoples posts, I hear about Apex seals, and about them breaking. I assume the apex is the 3 points on the rotor <- (Is that the correct term for the part that rotates?) but what are the seals, and what do they do?
