Cast iron can be welded, but don't attempt it unless you are an experienced welder as it is very difficult. You can make the problem worse.
Depending on where the crack is, you may be able to fix it with ';JB WELD';. This stuff is very good, however you will have to make sure that the surface is super free of oil before using.
yes or there are other weld-free that you can buy that work real well. I've used them Volvo truck airtanks in the past.
