Did mine yesterday, gasket was rock hard.

All in all I didn't find it that difficult. Once I got the alternator out I removed the one torx head holding the oil lines onto the housing and removed them. From there it was pretty easy to get to the three e-torx. I did not do anything with the power steering pump, this resulted in the socket going on to the one bolt at a slight angle but I still managed to get it loose. I replace all three e-torx bolts with socket head cap screws and then reinstalled with a ball headed hex socket. Much easier that way.
