Technical Exhaust Manifold bolt snapped in HEAD

[*welsh.wizard*]

... Hi all,


Just had a new head fiitted on my car after the gasket going on the other one. All fitted into place and the last exhaust manifold bolt to go in wouldn't do so. Checked why and it turns out that the head was sent down with an exhaust manufold bolt already snapped off in there - Yes I should have checked it, but didn't.

Note that this bolt is snapped in the actual head, and NOT in the Exhaust manifold itself. I know sdace is limited, but is there a way to get it out WITHOUT having to take the head off again?

Many thanks.

I had this happened to a car i used to own (had to drill 6 of them out)
I did it in situ, i carefully used an angle drill and a stud extractor,
Get a sharp punch and punch the center of the stud as hard and deep as you can to stop the drill wandering, then Drilled down the center of the stud and hammered a stud extractor in.
I used an air angle drill because the heads are a a lot smaller.
The studs were sprayed with penetrating fluid overnight, that helped.
