Has anyone come across rounded valve nuts on the rocker arm, and how have you fixed it? I guess the only thing I can do is use a bolt extractor but the space is tiny and I don't want to drop metal pieces into the head. I searched the archives and one guy broke his engine by cracking the rocker arms. I don't want to do that.
Cyl #4 intake valve nut is completed rounded, its clearance also way out and it clacks loudly, so this must have been damaged a while ago and kept getting skipped.
I adjusted the valves on all others and it's much smoother now and quieter. But there's a slight shake and you can easily hear that one rocker arm banging away. Wondering what I can do to fix it without taking the head off, or if I should just leave it alone because it's working.

If it's just the nut that's rounded, take a vice grips to it. It's only a 6MM bolt, shouldn't take much to get it off. And being where it is there shouldn't be any rust in
there.

I did try the vicegrips I have, but they were too big and the space (right underneath the throttle) is very limited. Just ended up making it worse so I stopped, plus everything covered in oil doesn't help.
I have some OEM BMW nuts and washers on the way, and I'll look at buying smaller vicegrips first, or whatever else they can recommend.
