Could someone help me ? I decided to check my spark plugs yesterday, when it was time to put the 10mm coil pack bolts back in I seemed to have ripped the thread out of the hole the bolt goes in does anyone have any ideas how to resolve this ? thanks

Helicoil

It's still head off to helicoil. I'd be looking for another head.

Head off to helicoil a pencil coil bolt hole?
I'd be able to sort that no problem

its not head off i dont think just the cam cover? machine shop/ engneering company should be able to do it in situ.
if not its cam belt off cover off and give it to them

When they drill & put the rough tap in to create the thread that hold the helicoil there will be swarf in the bore. Personally I wouldn't rely on vacuum & compressed air to get it out.

Again
Why will there be swarf in the bore?
You don't even need to remove the plug

If you don't remove the plug how you gonna get the helicoil in between the plug & the head. I had to do it on 1 of my old 2 stroke bikes & there was quite a bit of swarf when I drilled the plug hole out in order to make the hole bigger so that the helicoil would fit

 

[Lemon]

no its for the 10mm that holds the coil in lee no the plug hole

Aah all is clear now. I've got with the programme. I was thinking it was the plug thread.
Anyway just incase the op doesn't know how to use a helicoil kit I found a how to.

Helicoil as said, i've done quite a few. Thread is way stronger after helicoiling, far better than the original (as it should be).

You can get the helicoil kit you need for around £15 from ebay and its a 5 minute job. Really not difficult.

Cool I took it down to a local garage where my friend works and he re tapped it a size bigger, i think 7mm so all is good. thanks for all your support
