Crack in oil pan

[John Cody Forbes]

Cast aluminum is hard. Also old aluminum is work hardened from vibrations. Oil pans on these cars crank easily. 

That said, it's entirely likely that OP could have hit something in the road or the mechanic parked too close to the curb or something along those lines.

On the drive home I noticed a lot of smoke coming from engine bay. I pulled over and checked oil level and I was down 2 quarts after driving about 10 miles. I added oil and got the car home for inspection and noticed oil dripping from a hairline crack totalling about 1 1/2" in the shave of a V near and around the oil drain plug. After much discussion with the mechanic who did the oil change, he flat out denied responsibility for the crack. Can this crack be successfully repaired with JB Weld on the inside and/or outside of oil pan, or TIG welded or do I have to source a new pan to fix the problem. I am just curious if there are any BTDT's that have used JB Weld or similar products to repair cracks in their oil pan. Any input is appreciated.
