How big of a crack is it?

JB Weld will hold. I have a friend that snapped a U Joint while we were camping/4x4ing in the trucks. He actually used JB Weld to hold half of the U Joint together. Let it dry for the next 2 days, he is still running that U Joint on his drive shaft. That was 1.5 years ago.

Yeah I have seen several people repair cracked blocks with JB Weld. If its done correctly it will hold fine and last as long as the rest of the bike. Make sure its VERY CLEAN and mix the to parts correctly and give it plenty of dry time.

Since it's a crack, I would drill a small hole in each end of the crack to keep the crack from getting bigger. Like they said, if you clean all the oil and grease off of it good and let it dry for the specified amount of time, it will hold. I've fixed some big holes in blocks, before, with JB Weld.

I would use Acetone to remove all the oil and grease. Acetone is good at dissolving oils and grease and it dries quick, without leaving any kind of residue behind.

Glad you got it fixed. That JB Weld is some good stuff.
