Why do Rx8 engines fail?

The problem is that there are so many different ways for an engine to fail: Excessive carbon buildup accelerates seal wear, causing compression loss (particularly a problem in automatic RX-8s) Excessive carbon buildup unseats the seals, causing compression loss (particularly a problem in automatic RX-8s)
