Default Can I weld a bung to the oil pan?

While my motor is out, I would like to have a temp sender bung welded onto the side of the pan.

Thinking opposite the oil drain plug.

Can the pan be welded?

It's aluminum just be sure it's done correctly and it should be fine.

Might have a hard time finding an aluminum bung
that's ready-made and going to stay in shape
through welding. I'd go with about a 3/8" wafer
cut from 1" round stock, drill a 3/4" pan work hole,
bung-to-be on the outside of the pan, weld from
the inside and put a bead around the outside too,
then drill & pipe-tap. Probably a half-hour job as
a welding shop carry-in, esp. if you do the hand-
tool stuff yourself.

You might also be able to find a compression fitting that would mount through a hole drilled in your pan. I'm not a welder but I might be a little worried about having the pan warp.
