well i currently have a hole/partially patched hole in my crank case. Long story short, i had a chain snap and put a hole in the case right above the front sprocket. The hole was a little bit bigger than a quarter. New cases can only be purchased in matched sets which would be $1100, and i was quoted about $1000 to tear the bike down and put it back together. So i tried taking it to a welding shop to get it heli-arced and that didn't work out so well. They tried twice and won't touch it again. Is there an epoxy i can put over the small leak now? Will blue glue work to seal this? Should i just try taking it somewhere else to have it rewelded, or am i just screwed?
