Hi, I am new to posting. I have a slight problem. Last Night my clio 172 blew a spark plug out (although I am not sure as I have not had a look at them yet) I have read a lot about helicoils but am Not sure if it is something I should attempt or should get a mechanic to do it if it has stripped the threads. Opionions welcome.

ideally, the head wants to come off to fit a helicoil. it'll drop swarf down into the chamber otherwise. i wouldnt send it to a mechanic, i'd get the head off and take it to an engineering place. a decent helicoil set isnt particularly cheap either
where in devon are you? i know someone in exeter who should easily sort it for you

Thankyou for the Welcome. I am hoping I can just go out to it take it apart and that it has not stripped the thread but if it has it will need a helicoil. I do have a friend who is a mechanic who does all my car stuff I just didn't want to bother him as he is really busy and thought I may be able to do it myself but if the head needs to come off there is not chance of me doing it. 
The last thing I want to do is drop anything into the head. Did think It might be an easy job but sounds like I will have to get the car towed back to my work and pester him to fix it for me. Thanks for your help.
Does anybody know the size of helicoil that fits the Clio 172?
Thankyou
Just a quick thankyou to the guys that replied to my last post about my sparkplug blowout. For once I was lucky and it did not do any damage to the threads, just smashed the HT lead apart. New set of spark plugs and New HT and she is good to go

Whichever has fuel
Fit a new set of genuine plugs, torque them up (65nm iirc) and go from there.
I wouldn't be taking the head off. I've had two done at a local engine place in the past, threadserts, and both are still going strong.
Danny at 519 automotive talked me through it and recommended it.

As above, Timeserts are the best way for plugs. I have a place in bridgwater do mine.
Cheers for the reply, Went out to look at the car last night and although it seems to have blown the sparkplug out and destroyed the HT Lead, The thread seems to be fine, Only time will tell when I put it all back together later. On another note I have a loud banging when the car wheel spins, I have read this is due to a worn engine or gearbox mount, anyone have any Ideas on that?

I've read elsewhere on here that 25-30Nm is more than enough? 65Nm sounds like quite a lot for plugs going into an ali head :S
