Known Issues

Apex Seal Wear:

Premature apex seal wear can occur if the engine is overheated, not properly warmed up, or if lubrication is inadequate. Regular maintenance and proper engine operation are key.

Carbon Buildup:

Carbon deposits can accumulate in the combustion chambers and exhaust ports of rotary engines, potentially affecting performance and starting. 'Italian tune-ups' and decarbonizing procedures can help.

Oil Consumption:

Rotary engines are designed to consume a small amount of oil for lubrication of the seals. Excessive oil consumption can indicate internal seal wear.
