The cleaning procedure described under the service bulletin is a long process and it is recommended to install the updated SSV actuator and gaskets.

Beautiful and prestigious car but to unreliable and costly to maintain

I bought a 2004 Mazda RX8 Grand Touring this winter. The car is beautiful but...where do I begin? When we tried out the car, there was a noise coming from the rear end.
