I was helping one of my friends install headers on his 99 F-250. It was going extremely wel until 2 of the studs on one side reused to come out. We have to remove the studs and replace them with bolts, because you can't fit the headers in place with the studs there. How can we get those 2 studs out? Once we get them out, it shouldn't take more than an hour or so to finsish everything up. Thanks for any help you can give.

 

I think if you look in the Official Ford Service Manual, they'll tell you to pull the engine and lay it on it's side.

Attach a vise to the stud the grab the vise with a chain hoist and elevate the engine..suspended by the vis grabbing the bolt.

Then wiggle the egine back and forth (using a certified maechanic to hold the vise) until the stud loosens up.

The rest is elementry.

The GM Manual will probably advise the use of a penetrating oil or the use of heat..and vise grips

 

Smart***. Use vise grips and if you can tap on the end of the stud with a hammer, sometimes this loosens the rust and helps out.

 

Try PB Blaster. It puts WD-40 and Liquid Wrench to shame. Spray the stud down, let it soak in for a couple hours, heat it up with an oxy-acetylene torch and respray while still hot. A couple cycles of this has never failed me. When complete, light your smoke with the torch in celebration and continue with the header install.

 

lol. Thanks for the laugh.

I don't have access to a torch, but I'll try out some of the other methods. Hopefully we'll get it taken care of soon.

 

They make a tool just for this. It goes on the end of your ratchet. They use to sell them at autoparts stores for $10.00 It is called a STUD PULLER. It has a round hole with some teeth in it to hold on to the stud. But before you do that put 2 nuts on the stud tighten then to each outher spray it with some pennatrating oil, tap it with a hammer to losen it up,drink 2 beers, then use your socket set not a wrench(wrenches don't pull even and you bend it or break it off) to take it off.
