I have a 85 500SEC that has a rocker arm that rattles. I was told it's a good idea to replace the lifter at the same time.

I've read the post and it seems pretty easy, but no one has mentioned how to remove the lifter. It has a nut shape to it so I'm guessing it just unscrews, but want to be sure. Are there any spacers or other parts to look for during removal? I have a valve spring compressor too.

Any help is appreciated.
