Default Best way to repair pin hole leak in new oil pan.

It is coming from the weld. This is a brand new oil pan. What is a good way to seal this up from the outside and still in the car?

As you can see it is running out of the side of the pan.

I had one like that. I drained my oil (mine was on the bottom) the reason for draining.
Scuffed it up with sandpaper cleaned it with carb cleaner and put RTV on it, and let it dry overnght.
I tried JB weld but it still leaked.

Did it ever start leaking again?

unfortunately the only positive way to fix the pan is take it off and tig it up. soft solder will work but the metal needs to be oil free and clean. i doubt any epoxies or silcone type sealers will work unless all oil residue is removed from the inside of the pan.

Looks pretty easy to pull that pan off by the looks of the pics. Why not do that?

Drain oil, let sit overnight with drainplug out...clean area well w/brake kleen & some air pressure....Score the area with a grinding disk, say 36 grit, and apply either "Panel Bond" (3M-8116) or 3M catylized seam sealer (2 part). Both products are designed to adhere too bare steel, aluminum, Wood,....whatever. Gaurantee positive results.....

Looks like burn-through from a divider welded in there. If it leaks now and the impression is as visible as it looks in that one pic, it will tear in the future.

If its new and its on a weld call Milodon . That shit is too expensive to just let go . If its a defect I'm sure they will replace it .

i would call the company you got it from and tell them send a return tag with my new undamaged pan. that cost too much to let go. why would you even consider sealant on a new pan ? or is it new to you but used . if thats the case pull it and weld it that way you wont have to worry later

It is a new Milodon pan that I bought a couple of years ago. I am finally getting the thing ready to drive. I started the engine a couple of times last Saturday to make some adjustments. So last night I noticed oil on my garage floor. I wiped the oil pan down because I couldn't detect exactly where it was coming from. Today after work I saw exactly where it is coming from.

It's a new build with a Procharger that has taken me a while to get going. I really don't want to take this thing out to change the oil pan.

Where can I get those products you guys speak of?

If it is truly a small pinhole. Take a good sharp center punch. Use the punch to distort the metal around the hole. Don't go crazy it only takes a little bit to seal it up. I have done this on hydraulic tanks many times.
