Title: broken stud .... No its not me, well.......
Post by: ZekeD on August 31, 2014, 11:23:50 PM

Actually it is in the exhaust flange at the bottom of the manifold. I soaked it in everything I could find for three weeks, put vice grips on the stub, tapped on the stud for hours, finally drilled the center and put an ez-out into it only to break the tap handle in three places.

Now I have rounded the hole and don't know if I can drill all the way thru into the exhaust chamber after/under the flapper.

a) Can I drill into the chamber, and if so do I worry about the chips falling into the manifold?

b) Can heli-coil or Tyme Certs be used in cast Iron?

c) Do I have to replace the entire manifold, or does the plate that has four bolts on it come off?

I just wish to avoid any more damage.

You have two choices. First drill and set a Time-sert, and install a new stud. Do not drill into the chamber. The four bolts hold the intake manifold to the exhaust manifold. Replace the gasket between them when reassembling.
