Brake clean, blow out cracks with air, wire brush, brake clean, blow out with air, propane torch until sweat is gone, weld.
Make sure to keep the pan fastened to something rigid... preferably a spare block. Aluminum moves a lot when welding.

You know of course that this is going to bring out all of the stories about brake clean, tig welding and death.

Yep. Believe it or not some people still don’t know about the dangers. Until it’s to late.

Some break cleaner doesn't have clorine

No brake clean, unless you're the type to play with loaded guns too.

Acetone or a dedicated aluminum cleaner from the weld supply shop. A clean, stainless brush. Aluminum, especially cast, will absorb whatever fluid it's in contact with to some degree. You may find that you have to get it wet with the torch and clean off the poop and crap that comes up out of the metal multiple times before you can get a bead to run. Using the propane torch also helps.

If it's cracked through a bead or a thick piece, V'ing the crack will help.

If the results don't match the theory, change the theory.

All metals will absorb oil. Wash with water based degreaser and bake in over at 400* for 5 hours. After cooldown, acetone wash, grind, acetone wad and weld. Makes the welding easier.

Argon at high temps is the issue. I don’t want anyone to be harmed using only part of my advice. Read my entire instructions and there is no issue.
Better yet... just ignore me.

Most people use green, pure tungsten. I use blue, 2% lanthanted for everything, steel or aluminum.
