And if the JB Weld breaks off the cam what other damage will happen.

I am working on a friends car. It is a '97 that they only had for 1 week. They brought the car to me with a horrible oil leak (engine was 3 quarts low on oil) and a 110K mile engine without any history. I put a new timing belt, water pump and seals in the car and then scrapped/washed all the old oil up. After putting the car back together I find that the intake camshaft has a bad gouge in it (well, more like someone took a dremel or something and cut a flat spot in it). Of course I didn't see this when I had everything apart! <G>. Anyway, I was fixing to order a used camshaft and started thinking that maybe I could try to repair it with some JB Weld and then sand it smooth. My thoughts are that it won't hurt to at least try to fill in the hole AND the camshaft is already worn with the lifters where another camshaft might not. What do you guys think? Do you normally replace the lifters as well? I am pretty sure the owner does not want to get too much invested in the repair (i.e. new camshaft and new lifters).
