So, what is a Mazda RX-8 exactly?

The Mazda RX-8 is a legendary sports car that was produced by the Japanese automaker Mazda from 2003 to 2012. It is known for its unique rotary engine, agile handling, and unusual rear-hinged doors referred to as ‘suicide doors’.

In total, nearly two hundred thousand RX-8s were produced between 2003 and 2012, according to Official Mazda RX-8 Sales figures. While the Mazda RX-8 boasts many positive attributes, such as its nimble handling and distinctive rotary engine, it also had its drawbacks. These included high maintenance costs, poor fuel efficiency, and surprisingly small cabin.

The most significant issue with the platform began to surface in the early models, specifically those from 2003-2004 (referred to as 04/05 models in the US). Shortly after its launch, there were reports of engines failing from low compression. The primary culprit was the notorious wearing of the APEX seals. This wear was often caused carbon clogging (coking) in the engine, which prevented the APEX seals at the tips of the rotors from sliding in and out due to thermal expansion. This restriction led to accelerated APEX seal wear, which in turn caused the engine to fail from low compression.
