Aluminum CAN be welded, but you'll need to remove the pan. That may require partially removing the engine. Pull the pan and have it welded. Suggest it might be cheaper to replace it. A shade-tree type solution is to use a metal-reinforced epoxy (like J-B Weld), but the area to be repaired must be free of contaminants & have the surface roughed up to provide "teeth" for adhesion. My teenage son took my '97 4-wheeling & put three cracks in the pan. I drained the oil, let it set for a few days to allow as much as possible to seep out, Vee'd the cracks with a tapered stone on a dremel tool, cleaned the areas with lacquer thinner, and slathered on the epoxy. Two years now & no problems so far!

Crack
The freeze plugs are designed to blow before the engine cracks on a 1997 Aurora. The process is not foolproof, and the block could still possibly crack.
drain it, chip out around crack repair it with a cement sealer.

Straightening an aluminum alloy wheel is NOT recommended. Aluminum wheels are both lightweight and strong and are capable of carrying the vehicle adequately... But DON'T try to straighten them. You can repair most aluminum sheet metal and some extrusions. It is recommended to use heat between 300 and 450 degrees Fahrenheit as aluminum tends to crack when straightened cold. If you heat the aluminum over 575 degrees Fahrenheit you could damage the aluminum alloy properties beyond repair. Measuring bare aluminum with a non-contact thermometer is not accurate because of its shiny surface. Spray a thin coat of gray or black primer on the area to be measured. With aluminum castings and aluminum wheels you can only repair cosmetic scratches. If they are bent or cracked, you should always consider replacement. If you try to straighten a bent aluminum wheel it can have cracks you can't necessarily see and could break out causing a blowout and possibly kill. If this wheel belongs to someone else, you need to realize that no auto maker recommends repairing bent aluminum wheels. I strongly suggest you get another wheel.
Are you talking about a crack in the engine block? Sorry, it's not repairable.
No, rims are very tough. It takes a very hard hit to crack a rim. Installing a wheel weight will not cause a crack.
Eventually a floor repair kit will appear at the store. Buy it and put it on a floor crack. You will need to buy three repair kits (one for each crack). Then put some one on the crack and they will fix it. If they walk away and the crack is still there, put them on the crack again.
I think it is aluminum sheet
