Cast aluminium engine casting hole, brazing rod or spool gun?

jeudi 29 janvier 2015

hey guys thought this would be the best forum to ask this



i recently purchased a dirt motor bike and the chain came off on the old owner punching a small 5x3mm hole in the crankcase, the crankcase is cast aluminium



i have three options



JB weld it (looks dodgy to new buyers if i sell it)



weld it with aluminum brazing rod



or



weld it with my spool gun



pulling the engine apart to repair such a small hole will result in me rebuilding the engine and spending $700-$1000 so its just not economical



what would u do in this case?
