Installing Heilicoil in cast iron - advice wanted.

[7HC]

Evidently they cover that too: http://www.timesert.com/html/sparkplug.html

Never had to use the timeserts, have used heli-coils. Timeserts might be the best tool for frequent maintenance items. Drain plugs take a beating. Even car dealerships hire ham fisted flesh eaters with visegrips for eating utensils. Motorcycles have a long history of stripped aluminum drain plugs, even though factory torque specs are very low.

Helicoils are fine for those who install them properly and respect fastener torque. Use them first (less expensive?) fix- Timesert has a fix for stripped heli-coils.

Thanks for the link, having a tapered collar is the only way it could work.
Next time I need to make a complete thread repair I'll try a Time-Sert, looks like they're readily available.

In regard to the collar at the top of the Time-Sert, while that may work to seal a plug that uses a flat compressible washer for sealing, how do you deal with a plug that uses a taper to seal to the head?

The inserts are - in this case - application-specific and come with the appropriate taper seat.
