These kits from Real Gasket Corp replace problematic pushrod tubes of continental engine models: A-65, A-75, C-75/85/90/125/145, 0-200, 0-300 and GO-300. The installation does not require loosing or removal of the cylinder and converts it to an "independently serviceable" spring loaded pushrod tube system, similar to IO-470, IO-520, and IO-550 continental engines. It also allows access and service to the lifters. 

The kit is designed for easy installation and uses real gasket's FAA-PMA pushrod tube seals as used in the continental IO-470, IO-520 and IO-550 engines. For certified aircraft engines, form 337 is required.
