JB Weld :worthy:

As long as it is not a stressed area you can get by with a JB Weld patch job.

What caused the crack is the important question.

looks like a stress crack near one of the bolts on the top side , after a good ride you notice some oil but not too bad , thanks for the reply

You may have a mis-aligned mount or missing a space washer or something. Need to correct the problem first.
