Applications
The EQ6989 kit is the premier solution for a complete engine top overhaul, typically performed for the following reasons:
- Low Compression: To restore engine performance when multiple cylinders fail to meet minimum compression standards during inspection.
- Cylinder Head or Barrel Cracks: The only approved solution for replacing cylinders found with cracks or other non-repairable defects.
- High Time / TBO: Used to restore the "top end" of the engine to new condition as it approaches or exceeds its recommended Time Between Overhaul (TBO).

Restore your engine's power and reliability with the unmatched quality of a genuine Continental Motors Top Overhaul Kit. Visit Airparts.aero to order the EQ6989 kit and ensure your top overhaul is done right.
A top overhaul is a major engine repair that involves replacing the cylinders, pistons, and rings—collectively known as the "power pack." The Continental EQ6989 kit is engineered to make this process seamless and reliable. The included factory-new cylinders feature precision-honed barrels with the correct surface finish for rapid ring seating and optimal oil retention. The valves and valve guides are installed and leak-checked at the factory, ensuring proper sealing. By replacing all six cylinders simultaneously with factory-new units, mechanics can ensure balanced compression, uniform thermal characteristics across the engine, and predictable performance, effectively restoring the heart of the engine to a zero-time condition.
Note: A top overhaul is a major repair and must be performed and documented by a certified A&P mechanic in accordance with the current Continental Motors Overhaul and Maintenance Manuals for the specific engine model. Proper break-in procedures must be followed after installation to ensure the health and longevity of the new components.
