I just went through this about 3 months ago, but my crack was much worse. I think the PO managed to hit a parking barrier and the crack finally let go. I was at work so I took it to my nearby inde to figure out where the oil was comming from and once up on the lift we found the crack. I got a ride home to pick up the truck to drive and just had him replace it that day. I came to about $600 if I remember correctly - not an easy remove and replace. Aluminum welding is not real easy and I would never do it around flamable stuff. You oil is flamable at those temps and emptying the oil pan without inerting it might make it worse. You might try JBWeld- you never know, but I think you would have to empty the oil and let it sit for a day. I think it would be hard for it to adhere to the metal without getting all of the oil film off - easier said than done with the pan in place and a small crack full of oil.
