Known Issues

Rotary Engine Apex Seals:

Wear or failure of apex seals can lead to loss of compression and engine damage. Regular maintenance and proper engine operation are critical.

Oil Consumption:

Rotary engines naturally consume some oil as part of their lubrication system. Ensure oil levels are consistently checked.

Vacuum Lines:

Aging rubber vacuum lines can crack and leak, affecting engine performance and boost control.

Turbocharger Reliability:

While generally robust, turbo seals can fail over time, leading to oil burning or loss of boost. Proper warm-up/cool-down cycles are important.

Cooling System:

Overheating can be an issue if the cooling system is not properly maintained. Radiator, hoses, and thermostat should be checked regularly.
