Ok guys, I dropped out my oil pan to clean it out before reassebling my 235.Well it had a bunch of sludge on the bottom by the drain hole. After scubbing it out it has several holes in it. It was suggested that I braze the holes. After going to town to buy oxygen it seemed to work until I ran out of oxy. (I just have a small hand held brazing torch). Is this a good way to go? Or is there a better way? The pan is in great shape other than where the sludge built up. Thanks for any input. P.S. I don't have a welder yet.
