Found a tiny pin hole size oil pan leak right next to the drain plug on my 283. I don't want to try to weld it because that would damage that flat machined surface needed by the plug gasket. Could I use body lead or solder from the inside? (the pan is off) Any other suggestions? Would JB Weld hold up to oil and heat?

Hello;
My Experience with JB Weld are many! Usually sucess is achieved if you use the regular JB (not quick set) Just make sure that the pan is very clean before applying and lightly "rough" the surface to be treated.
My 2 cents worth!

weld it and file the outer plug surface flat with a file.

Weld and file - 3x. JB has it's place - but not protecting an engine where failure can be catastrophic.

A pin hole leak might suggest rust on the inside.
I have seen this on a fuel tank, the diesel (or oil) will float on top of the water, even a small amount right down by the drain plug maybe.
If it isn't rusted I don't see why lead or solder wouldn't work, there's no pressure and they solder copper water pipe all the time.

Give this a thought.
JB Weld isn't going to stick where it's needed - on the oily crack or hole.
Likewise for welding - the oily flaw is going to contaminate your weld. But at least you have a chance to burn through it or around it, or cut the flaw out then weld.

You can flush out any oil in the hole with brake clean, but be sure to flush out the brake clean with water as the residue and vapors are very flammable. I'd weld it as well sice you have the pan off. Easy enough to file flat again.

Agree with Rick.
Weld, solder, JB Weld -- whatever you do, you have to bond to a super clean surface to expect it to last.
If the pan is off, i would clean it very well and then pre-bake it to boil off residue.
Then i would solder the hole.

Thanks all for the replies. I'm sure it was rust issue from the inside plus it looks like someone had pushed the bottom of the pan back out at some point, leaving a few small dings. Think I'll try going with the solder idea.

Beware of Chinese replacement stock oil pans!!!! Generally, they are nothing but more trouble than they are worth and will leak like a sieve. It's always best to try to repair your original if at all possible, or buy another original, USA made pan. JMO.

DO NOT DO THIS!!!!!!!!!!!!!
Brake clean is highly toxic and when you weld behind it the gases could KILL you!

That was why I said to flush it out afterwards. Nothing should remain of the brake cleaner if it is flushed out.

A good cleaning before trying to repair is the trick. I have brazed a few original pans with good success. I wouldnt try to weld one, metal is thin (especially if there is a rusted thru area), but brazing flows better and wont warp the surrounding area.

I would find an american made new one or a good quality used one.
