Known Issues
Apex Seal Wear:
One of the most critical known issues for rotary engines. Symptoms include poor compression, difficult starting, and reduced power. Regular oil changes and proper engine warm-up are crucial.
Sequential Turbo Failure:
The complex twin-turbo system can be prone to issues if not properly maintained, leading to loss of boost or overboost.
Oil Metering Pump:
Failure of the OMP can lead to insufficient lubrication of the apex seals, accelerating wear. This system often requires periodic maintenance or upgrades.
Catalytic Converter Clogging:
Can occur with prolonged rich fuel mixtures or oil burning, impacting performance.
