I have a 2000 F150 4x4, with the 4.6. I have a manifold leak, and the sound is very anoying. I have been doing some looking into it, and it seems like it is going to be a headache, Cause the hardest part is going to be removing them. A few people have told me that they are pretty sure I will break one of the bolts and have to tap the block. I live in canada and drive on salty roads during the winter.

What did your manifold replacement go. Would you think a couple of guys could do it in their garage, or should have a dealer do something like that.
