My truck is leaking oil, it is a slow leak that collects around the drain plug. When you look at it, it looks like it leaking from around the oil pain gasket. I took it to the dealership and they changed the oil pain gasket, 700 miles later it started leaking again. I took it back to the dealership and they changed the rear seal. It has been about 300 miles and it starting to leak again. The block and the front of the oil pan is clean. What do you think?

There is a cover that the rear main seal goes into that attaches to the rear of the engine and there is a gasket there that leaks.
