I wanted to thank this page for leading me in the right direction. I've had my rx-8 and took it for a compression test like the page recommended. My rotors were 5.2-5.9 which is in the failing range. My 2007 rx-8 with 85k miles was still covered by the Mazda warranty so they will be putting a new engine in next week free of charge.

 

 

That's nice of Mazda.

 

I meant to type I've had my rx-8 for a week Thanks guys....and yes it's nice of them.
