I hit a rock on the COBDR 30 miles outside of Gunnison, CO, which put about a 1/2" area dent and hole in my oil pan, causing a large leak. The aluminum got press in so there is about 1/8" gap in a semi circle in the dented area. Any tips on a repair? Would JB weld work good enough to continue on the trip? How long do I really need to let it cure before driving again? My thought is to clean it up, rough it up, JB weld, add oil. But if there are better ideas I would like some advice.
