A little update... I talked to the service technician a bit more about this. There was a large part list needed and BMW estimates 40+ hours of labor. Guess I should've bought the extended warranty, but I'm always hesitant with whether they would follow through.
guess I will just deal with it or trade it in. He was telling me that the N62 engine in the 7 series and 6 series do not have this problem. Those actually have different issues come up. He said he talked to an engineer on the engine and they assume it has to do with the torch on the engine which cause the seal to fail.
