    There are various porous metals used for bearings - not all are bronze colour.

    Since you have it apart, you can soak the bearings in oil - some people heat the oil so any air in the porous metal expands and escapes - when it cools down again, the oil is drawn into the voids in the porous metal.

    No, just replace the bushings with a sealed bearing. Then they won't dry out or be affected with any oven gases. Wouldn't the fan being on keep the gases out of the motor area? Or do you run it without the fan some time?
