I have a 2012 X5 N55 and I had to replace the lower oil pan gasket in 2020 at around 103k miles. I would recommend buying a Lemforder front suspension arms kit and replace them , bushings will be worn and have a lot of play. I replaced the lower arms and tie rods and had an alignment done after. Also I replaced the motor mounts. Also did front diff oil change and seals. ($840 labor and $1,700 in parts)

Also FYI I did valve cover gasket myself a few months before this.

Right now, no drips of oil and I am at 110k miles now. My indy mechanic keeps checking the oil filter housing gasket but so far no leaks from that , knock on wood.
