Seized upper control arm cam bolts

Yeah, this happens sometimes. I've only ever seen it on my parts cars, fortunately. Unfortunately, the only solution is an oxy-acytlene torch to heat both the head and opposite end red hot, then let it cool a while. It should break loose. If it's really bad, you'll have to cut through the bolt and bushing all at once. Either way, the rust likely has compromised the cam bolts. You'll need replacements.
