I appreciate the tip. At this point, though, if I can manage to get them out of the engine, I'm just going to replace them with stainless. I can buy the stainless metric bolts just down the street, and I have to believe that if the OEM bolts rusted this bad in the first 24,000 miles they'll probably do the same or worse in the next 24,000.
