durafix/ alubraze/ easyweld/ aluminium easymelt easy braze rods

you clean the area with a stainless steel brush, that should only be used for this job, the longer you brush the easier it flows. you want every remnant of aluminium oxide out of the way
you can't do this with brass or normal wire brush has to be new clean stainless brush

you heat the aluminium until it burns off sharpie ink and you feed your rod in like gas welding

used it on cracks in none load bearing sections of motorcycle casings to stop the oil getting out

works

you are basically gas soldering with aluminium ish "Monkey Metal/Pot Metal" rods

need a small tip propane torch 1/4 inch with good control, and you need to be aware that aluminium turns liquid in the middle while holding its external shape and then collapses so be careful with the heat you don't want to go that far.
do it with the drain plug in, less chance of it going WOOF in your face
I'd just fill the sump with mig welding gas and cap everything off. its a heavy gas but will rise when hot

The threads stripped out of the drain plug on my Hamburger oil pan in my 70 Dart race car. I drained the oil out all week, and decided to weld a 1/2-20 nut. I just finished welding, when I guess was a combination of race oil and fuel fumes blew out the drain hole with a bang and coated my welding helmet. Couldn't see out of it , and could not get from under the car fast enough. It did work, but I would not suggest welding in the car

A safe way to pull fumes out thru breathers would work. But vacuum motor might set it off, too. Any evacuation might've helped.
Hopefully no other leaks now.
I no longer remove drain plugs, when I can almost always suck oil out with my Boat Oil Change Pump. You push tube down into dipstick tube until it hits bottom and turn pump on. Then twist hose to get in lowest spot. When oil stops flowing twist again to be sure you got it all.
Some imports, you can remove oil filter & put hose into oilpan thru drain back return hole, a direct shot.

lol, used to that stuff; but I used a hose feeding exhaust from another running car to fill tank with no oxygen. A little flame outside the tank, quit flaming soon after. Today I shudder at what I used to do!

I've welded gas tanks that way. Carefully!

Changed my oil couple days ago and today notice a drop of oil on the floor. And a drop forming right under the drain plug.

It's a 15 year old Milodon pan that has worked great. Until now. Finally deduced it's a small chip out of the weld just below the drain bung. Maybe when I took it out it cracked. Very tiny seepage.

So drained all the oil, have it on jackstands so the front end is tilted pretty high. High enough to empty the back of the pan.

My thoughts were tomorrow, clean the snot out of that area and apply JB Weld.

If anybody has a better idea that's easy, let me know. NOT going to pull the pan and re weld for such a minor seep.

Why pull it? Hit it with a mig and be done with it.
