<VV> Nightmare on Corvair St....

[Rusty Hitt]

After 5 months I got my 65 140 convt. Back from my mechanic.  Driving it
home it launched at sparkplug.  I limped on home and decided to email
this group. I don't want to take it back to the mechanic for another 5
months.  What do I do.  I put the plug back in but it just slides in and
out.  I have heard of heli coils but I am unsure of what they are and
how they work. Is it possible to fix this situation with out pulling the
head off.  Any suggestions would be appreciated.
