Did you change the oil filter yourself and did you coat the rubber ring at the top of the filter with oil first? Besides the "put a couple of quarts in the torque converter" we have talked about in the past couple of weeks, the "oil the top of the new filter" is a garage trick that always needs to be done.
There is also the paper gasket between the oil filter housing and the block that can leak.
And X2 on the BOP 1 piece steel reinforced pan gasket. My new 455 had a lot of crankcase pressure until the rings seated and it blew the rear piece of the OEM style 4 section pan gasket out. The new BOP gasket took care of that (and the miles to get the rings seated).
