Hi, My lower oil pan was just replaced at 11,000 miles do to leaking.When I first noticed the leak around the bottom of the bell housing I found all the bolts on the oil pan were loose. I tightened them thinking this would help seal the gasket. 2 weeks later it was still leaking to I took it in to the dealer and was told there is no gasket used on the oil pan only rtv silicone and once it starts leaking GM requires the pan to be replaced. I have about 500 miles on it since the repair so we'll see what happens.
