The aluminum head on my Alpine was repaired at some point in the past with a
helicoil insert. I am in the midst of replacing the intake manifold and the
coil threads seem to have been damaged (I believe the end of the coil is bent)
so I need to remove the old one and insert a new one. I really do not want
to have to remove the head and am hoping I can just do with with the head
still installed. I have never worked with helicoils before, but the process
seems simple enough. However, there is not much online on removing them.
Does anyone here have any suggestions or advice? I see that there is a
removal tool out there, but that seems like overkill for one coil. Can I use
a screw extractor? Bend the end of the coil more and unscrew it with a needle
nose pliers? Any recommendations or suggestions will be appreciated.
Thanks.
