Where does your oil level settle cold in an IO-360? My operating level is slightly below 6 quarts. The engine will literally blow out anything above that. POM states 6 quarts to be a minimal operating level and my engine will not hold anything more than 6 quarts. I recently changed the fill tube gasket and could see the oil at the base of the case so I know the case is full. Even considering the surface area of the sump another quart would have pushed the base level above the bottom of the fill tube.
Thanks for any feedback!!
