Motor mount
I have a broken motor mount on the driver side of my '92 F150 4.9L M5OD.
I am having a very hard time getting the motor mount off. The nuts will not budge. Can anybody out there give me some direction here or should I let a shop handle this one?
Thanks for any help you can give me.

Take a propane torch and some WD-40. Heat the nuts with the torch and get 'em nice and warm, about 350-400 degrees (no, we aren't trying to make them glow). Then douse them with the WD-40. Try not to use P.B. B'laster (my normal fave) because the high solvent content (what helps it penetrate when cold) causes the bulk of it to vaporize. When using heat, use WD-40. Spray them liberally with the WD untill they stop smoking. Then try it. This works most of the time. Once you get them budged, switch to P.B. B'laster to keep them lubed. I think that you will have success. Of course, since we are talking about using open flame, keep a container of water and a dry chem fire extinguisher handy. If a fire starts, douse it with water. If it keeps burning, then hit it with the dyy chem, but now you have a mess. Chances are, though, you won't have a fire if you clean the area before starting.
