311543 OMC GROMMET VALVE COVER

The OMC 311543 is a rubber grommet designed specifically for valve cover applications on Johnson/Evinrude outboard and inboard engines. This sealing component prevents oil leakage at the valve cover and engine block interface, maintaining proper lubrication and protecting the engine compartment from oil spray. The grommet is an original equipment manufacturer part made from durable rubber compound formulated to withstand engine heat and oil exposure. Replacement is recommended during routine valve cover maintenance or if oil seepage is observed around the valve cover.
