Broken stud in head: How to remove?
The stud nearest the firewall on my friends 1990 300D 2.5 turbodiesel is broken off in the head. It appears that there is no exposed thread in the head, in other words it must have broken off flush with the head.
I've drilled into studs like this before and then used an extractor to remove, all with the head installed and the manifold not removed. I've been lucky before in getting them out. It's a huge pain to do this.
First of all is this common with the diesels? My friend just got this car and I'm fixing it up for his mother. New suspension, exhaust system and much more. Trying to make it as nice a possible.
I'm wondering if I should let somelse tackle this stud. Or might there be some new device on the market that I don't know about to get this stud out.

i removed one in a jeep.... real pain when the extractor (aka easy out) breaks..... the star pattern is better than the twirly ones
What you can do a few days before is to soak the bolt w pb blaster, or if you can get your hand on something called kroil.... mail order only.....
what i did what to drill bolt.... and we were lucky as being dead on center.... just a thread or 2 where shaved.... it has been holding for about 1 year
