[FWDLK] Broken bolt

["dirt rider" <drt-rdr@xxxxxxxxxxxxxxxx>]

Hello again all, here is where I stand with the 56 Savoy 6 cyl. One bolt
broke for the thermostat housing. I drilled a hole all the way through the
bolt, put in an easy out and guess what, the easy out broke in the bolt. I
think they pretty much suck since I didn't really put much pressure on it
before it snapped. I snapped it with one hand on the little t-handle wrench.
Eventually after drilling and pounding, I got the broken piece of the easy
out through the bottom of the bolt. I then drilled the hole bigger. I now
have a hole drilled the size of the original bolt, but there are no
salvageable threads. I tried to start a tap, but couldn't. Should I be able
to tapp this type of metal, or should I drill the hole bigger and try and
put in some kind of heli coil. The only thing I've ever heli coiled was a
spark plug hole in an aluminum head. At this point, I'm unsure what to do
and I'm stuck with a hole in the head. At last resort if I can't tap a hole
could be to epoxy some kind of stud into the the hole and then put the
housing over the stud and secure it with a nut. But I'd rather do it the
right way. Any input would be greatly appreciated.

Thanks,
Nick
