My mistake Bo, thought it had snapped off at the base (so to speak). (Read the phooking thread springs to mind. sorry). When faced with this sort of situation don't snap a tool off in the stud, like I did on one of the EM studs! That's a whole new ball game!

Glad you got it sorted!

Forgot to mention... MOLE GRIPS!!! (just ask Stu about my EM studs!)

I get quite a few jobs like this brought in to work, which people have had a go at.
The only fail safe way of removing studs which are broken flush, is to drill them out, but only in a milling machine where the job is clamped to the table, and not with a drill, as this will wander off course. Use an end mill first, then drill out. This is most important with aluminium heads, as the head is a lot softer than the stud.
We also spark erode a lot of studs, due to people using those bl**dy useless easy out things, which almost always break in the hole, unless they are very big.
Another tip, for studs which are flush or thereabouts, is to weld a washer to it, Place a washer over the top of the hole/stud, and carefully weld the washer to it. A couple of dabs a time with the rod, and it will weld the washer on, and more importantly warm the stud, which should then be free in the hole. Use a mole grips then, or you can tack a nut to the washer.
Also use the above on studs with plenty of length protruding. Weld on the nut, and away you go.

Good advice, but we don't all have welding equipment handy. The biggest problem though, is we are ALL too Proud to ask for help until it gets really bad!

Had a stud break on me when checking everything before putting the rocker cover on. I doubled up 2 nuts and locked them. came out easy. Depending on how much you have to play with.
