Known Issues
Apex Seal Wear:
Premature wear of apex seals can lead to loss of compression, misfires, and engine failure. Proper warm-up and avoiding extended idling are critical. Premixing 2-stroke oil with fuel or using an effective oil metering system is often recommended by enthusiasts.
Catalytic Converter:
Overheating and failure can occur due to unburnt fuel entering the exhaust, often caused by ignition or fuel system issues. Can lead to engine damage.
Oil Consumption:
Rotary engines naturally consume oil as part of their lubrication system. Regular monitoring and topping up are essential.
Starter Motor:
RX-8 starters can be weaker than typical engines due to the higher cranking speed required for a rotary. Frequent short trips can exacerbate this.
Ignition Coils:
Ignition coils, especially trailing coils, can fail, leading to misfires and potential engine damage.
