Was it mounted in the manifold or the up-pipe?

What you need to do is to get an adapter fitting that is bigger than the threads on your fitting as it is right now. It will have threads on both the inside and the outside.
Drill out, tap the manifold for the outer threads for your adapter fitting and install.
Reinstall the probe in the new socket and be done.
Unless the threads are barked up on the probe, then you also have to buy a new probe.

It is VERY helpful in this instance to also buy a new drill bit and thread cutter for this job.
Cast iron ( what the manifold is made of ) is very easy to work with if you have sharp tools. Very difficult and brittle if you do not. Use cutting oil on all the bits and it will work in your hands like hard clay. Very easy.

I think Kwik got your answer.

Yes and no.
The engine will run ok, but with reduced power because of loss of drive pressure for the turbo to build boost.
The no part is that hole is shooting out hot exhaust gasses onto who knows what?

You'll just have an exhaust leak but I don;t think it'll hurt anything.

Update:
Re-drilled and tapped the EGT probe with a 1/4" x 1/8" brass bushing, worked like a charm. Thanks for the help guys!!
