47-55.1 Chasing annoying oil leaks

since you have an actual crack and some deformed steel already, possibly due to a hit of some sort, you could try the clean and braze idea since it requires less heat. I have had decent luck using toilet cleaner to clean and degrease the area but just know it will start to surface rust right away. use a good flux covered brazing rod, if using bronze or brass, or use a good metal cleaning flux if using nickel/silver. try clamping the pan down to a solid flat surface before heating it up with brazing. you could make a wood frame and screw it down through the original screw holes.
