I have a crack in my cast iron oil burner that is in between the 2 rectangular clean out openings right at the bottom of the lifting eye. It seeps water when the furnace gets to the top of the heat cycle and stops as the temp/pressure subsides. I'd estimate it is about 1"-1 1/2 " long. Would this crack also leak into the fire chamber and is there anything I can do externally to repair this? I'd like to limp through the winter with this unit if possible. Any help would be greatly appreciated. Thanks- Mike
