Is this rotor housing done?

If you divide the housing vertically, exhaust/intake on one side and the compression/ignition on the other, it looks like a lot of chatter on the exhaust/intake side. Try acetone to clean them up. Pros use it, I've used it; it seems to work well.

So, you think the burning is on top of the chrome plating and not a sign of the plating being worn off?

Off to the store I go.

Wow, that oil residue didn't come off with that much cleaning...
Previous owner using synth oil?

Yeah, the high mileage explains a lot.

What's weird is that if the residue was made by normal, mineral oil, it should've came off with all that washing...

I am the only owner. I've had it for 20 years.

I hit it with the acetone and it took off some of the varnish, but still left the dull finish on the chrome. Pics later.

No, if the chrome plating were to have been worn or scrapped off, you would know it.
Chrome tends to flake and peel off.
You can feel it with your fingers (nails).
If you've ever seen high mileage 12A rotor housings, you'd understand what I mean.

The residue is definitely on top of the chrome surface.
The apex seal chatter has a lot to do with all that residue on the rotor housing...
