Removing Broken Head Studs

Perry,

If you don't have an "easy out" you can try drilling a small indent in the remaining stud surface off center but away from the threads. Insert the point of a punch in that hole and tap with a hammer. The punch should be angled so that the force of each tap tries to cause the remaining stud to back out of its threaded socket. Once they break free, they've been fairly easy to remove when I've tried this in the past. Be cautious about getting too close to the threads. Letting it soak in light oil should help.

I just got finished removing one from my TR3 that left me enough stub to get a small pipe wrench on the remaining stud. At first I thought it twisted off flush with the head.

On the negative side, last year I twisted off an "easy out" in an exhaust manifold stud. I ended up taking the manifold to a machinist to remove the hardened "easy out" and the stud. He was able to put a threaded insert in the hole after he removed all the junk. I'm still using that manifold. The point being, if it gets worse you still may have options other than a new head.
