timecert question, helicoil uncoiling Options

[VaccaRabite]

The skinny:
Spark plug helicoil is going bad - uncoiling out of the socket. I know that I want to timesert it to fix the problem.

BUT

Since the socket has a helicoil in it (that needs to come out) what size timecert do I need to get?

ALSO

How do I get the bad helicoil out of the head without doing further damage to the head? The head is off the engine, so I am not worried about bits of coil falling into the cylinder.

This site has MANY sert options, but I don't know which one I need. HELP?!

Sweet jesus!
$150 for the install tooling, $8 for the insert.

At least for the first place I called.

Hey Root, you got the stuff to install a timesert in your shop? If not, I think I'll farm this job out. If I had to do more then 1 I could justify the cost of the tooling, but for just one job, its probably cheaper to farm it - especially since it seems like I only need 1/2 of the tooling to do the job.

What size tool do you need?
If you can let me know the size or tool # I can prolly get one you can borrow from my machinist buddy. (IMG:style_emoticons/default/aktion035.gif)

Honestly, I don't know. I can give you the part numbers for the install tooling, but I don't know what that includes. I bet Crusty or Len knows, though.

Here is what the website says (part number is 4412):
4412 NOTES:

M14x1.25 spark plug repair short tooling:
Normally used on vehicles that the spark plug is clearly visible,
or heads that have the spark plug near the surface.
Other examples would be motorcycles, lawn mowers and many
out board motors. These applications would not require long reach tools.
The 4412 kit is used for washer seat as well as tapered seat applications.
The installation is exactly the same for taper seat or washer seat you only
need the appropriate length/style of insert.
