Thanks for your cover suggestion, PM and photo. I was aware of them but didn't know San Jose BMW still made them.
I've always had mixed feelings about them (minor point as I'm not really sure I like the appearance of the cover). However, I will reconsider getting one and trying it on---it could turn out to be a nice touch since Berlina is kind of Darth Vaderish in a way.
I still need to attend to the throttle body springs that are rusting. I got some CLR gel the other day that I will brush on and let sit for a spell, then rinse off and dry. Hope that removes the corrosion, then I could spray some Niox (antioxidant spray made in Australia that works) on them before installing the cover.
Meanwhile, I got some new Cratex wheels for my Dremel, so I'm going after the lettering on the crank cover on my next day off...
Appreciate the suggestions as always.
