Weld a wrench or socket to the bolt. The heat will help break the threads
loose and the welded on socket won't slip. You are probably suffering from
galvanic corrosion which is caused by dissimilar metals in contact with each
other.

Subject: [Roadsters] OFF topic manifold question 92 Ford Ranger
Sorry for a Ford Ranger question on the list but with the wealth of
knowledge
in this family maybe someone can offer a suggestion.
My 92 Ford Ranger I use only to plow my dirt road. The exhaust system came
apart at the V6 manifold taking due to rust a chunk of the drivers manifold
with it.
The manifold is bolted (not studs and nuts) with 3" long bolts with tiny 10
MM
heads. Even a 6 point socket starts to round the head of the bolt. I don't
think putting a torch to it will do the aluminum cylinder head any good. The
bolt threads are buried and can't get penetrating oil to. I need to get this
off. (grind it to bits ??????? )
ANY THOUGHTS
Dave
