I would say its got to come off. one tiny bit of swarf left in there and it could stuff the bore.

friend drilled out a sparkplug for me and just loaded the drill with grease,drilled slowiy and cleaned it often,changing drills if they got too hot.We blew it out with compressed air and then fired it up with no plug,still going now with no apparent problems!I suppose it depends on the value and/or age of your motor!

The vast majority of the time it is done with the head in-situ Fuglyduck.
Find someone careful and you have abetter chance of the engnie lasting years and years

As per the feedback from Les 6. But do be aware that a mechanic may refuse or say all care no responsibility re the swarf.

we took a van to a engineer to get 1 replace, it looked like tricky job, but they had all the gear to do it with the head in place, just a warning if the helicoil is not locked in correctly it can came out with the sparkplug when changing them.

have done it in place, used a 1/4inch piece of copper sealed to vacuum cleaner hose and sucked it out

engine reconditioners in cambridge did a heli coil on a ford courier FE motor. it lasted about 5 years until it popped the plug out about 6000rpm. we had it re- helicoiled and goes mint stil. done in 10 mins while still in ute.

Yep, this. And if theres a few shards of alum (is the head alum!) its all going to be gone after a couple of revolutions!
