In the process of replacing a broken rocker arm and leaky (oil only) HG on my stock 1987 325is with ~240k mi.
Question #1:
My valve stem seals are ancient and hard as a rock (and leaking tons of oil). How do I remove them? They're so hard and brittle my needlenose pliers just break them into pieces:

Question #2:
I have some light scratches on one of my cam journals and head. I can catch them with my nail, but they don't seem to be that significant. I've seen others with more scratched cams that need them replaced or polished, but I feel like this probably isn't that bad. What do you think?


Thanks!
