- Just another idea that worked for me once:
-
- 1.
- Use a thread cutting die to make a thread on the stud -- fortunately your '
- problem' stud seems to be long enough to do this.
-
- 2.
- Screw 2 nuts onto the stud and then lock them hard (i.e. turn the bottom
- one anti-clockwise whilst turning the top one clockwise using two spanners
- simultaneously).
-
- 3.
- If you've an arc welder (usual precautions!!), tack the two nuts together.
- (This is an optional step.)
-
- 4.
- Soak the thread in a freeing agent (as per the general advice already
- offered) -- a little hint here that you might like to consider is to get a
- wad of kid's modelling putty (we call it "Plastercene") and make a little
- cup or bath around the stud and which is stuck onto the manifold. You can
- then fill this with your freeing agent to keep it in contact with the stud (
- soaking) -- otherwise, if the manifold is still on the car, the stuff just
- runs off and very little will get where it's ultimately supposed to go. *
- Best to leave it soaking overnight IMO*.
-
- 5.
- Now take your spanner and apply it to the locked nuts, gently working
- the stud backwards and forwards (clock and anti-clockwise). As another
- chap has stressed: Patience and Perseverence.
-
- Main assumption is that you can get hold of a thread-cutting die. If you
- can't, ignore!!
-
- Best of luck,
-
