[FC] Broken Valve Cover Bolt

[Keith Hammett]

I had an exhaust stud break on me where I could not easily drill it out.  I
was able to use a flex shaft and diamond tipped bit with a dremel to eat out
the stud enough that I could then use a pick to get the threads out.  I
managed to save the threads and was able to clean them up with a tap.  It
did take awhile but it was my only option.  Good luck.

I have a valve cover bolt that is broken off just below the surface of the
head.

I have a Helicoil repair insert if I need it, but does anybody have any tips
on getting the old bolt out.

It looks like it would be pretty hard to drill a small enough hole  to get a
screw extractor in there.

Any ideas?

Thanks,
