Engine case question

I had a thought earlier today, on my ZX what is the engine case made out of? I had a thought of welding it back together and doing the rebuild it needs. if I can figure out what the case is made from I can determine the proper welding method to fix it, and make it ridable.

its either that or replacing a motor, and I dont want to spend that kind of money on a new motor/tranny combo.

I'm thinking magnesium is it. theres one easy way to find out.... I'm gonna get some of the loose chunks and have someone with a metallurgial background tell me.

whatever it is, its surely cast. I dont know if you can cleanly weld cast metals due to its porosity. I may b e wrong though.

ok i did some looking; cast aluminum can be welded but needs to be welded with superalloy 5 only.

If it is magnesium I wouldnt recommend welding it cuz it will catch on fire and burn out of control untill it is all gone. And water makes it burn faster. So good luck!

Oh for the record, there IS a way to weld magnesium, but it requires special equipment and knowledge to do so.

It's Magnesuim. I took mine off to get chromed. I had to pay extra because it's takes a little more work to chrome it.

I had a boat motor fixed like this once. It held up for three more seasons and blew a hole in the other side.
