The crank case gas a 2" X crack. Is crank made from steel or Al? I was thinking of having it professionally welded if less than $60.
Or using a Mg sparkler ;
I was watching youtube about using JB Weld?

AL alloy...excuse me for chuckling about JB! 8^)
The crankCASE is aluminum alloy. The crankSHAFT is steel

I know guys who have used JB Weld on crankcases. The repair has often
started leaking oil within a year or there-abouts. You NEED to get it
CLEAN before patching to stand even half a chance.
