Generac 0E9366 Breather Gasket fits the 530CC engines found on the 10kW, 11kW, and early model 6kW EcoGen Off Grid series units & Portable Generators. This is a common source of engine oil leaks on the 10kW and 11kW units.
The 2 screws should also be replaced on older 10kW units with the new style that include lock-tite patches on them. If not, be sure to use a temporary thread locking compound on the old screws and clean them with a suitable parts cleaner before re-installing.
Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, & Bryant.
