I believe our valve covers are just plain ol' naked aluminum. At least it's
pretty naked nowadays. And I think they originally came unfinished
(possibly a thin layer of some clear finish, but I think not).
Sandblasting would certainly freshen it up, but that's not quite in my
category of "painless". I want to get it back together as soon as I locate
a new Allen-head bolt to replace the stubborn one
By the way, I guess I exaggerated about the timing belt looseness. When I
rechecked, it was nearer to 1/4" deflection--not 1/2". Peter S. says
"should be able to be twisted without too much force, when held between
your thumb and fore finger", so I think it's not far from that.
