Spark plug Helicoil/Time sert

[SimpleJoee]

Right, after yesterdays mishap with a random misfire and Clio based suicide, I've diagnosed the problem. The spark plug in cylinder 2 has popped out of the head, I just barely pulled and it came right out. The plug itself is fine, as is the thread (along with the other 3, all lovely) but when trying to re screw it back in, it feels as though it's jumping a few threads, and then biting near the bottom if that's understandable. Tried swapping plugs with each other, same result. So I'm guessing this has torn the thread, and I'll need Helicoiling/Time serting? Obviously I won't be doing this, as it's a head off job if I'm correct. What sort of costs is this probably going to set me back? I appreciate every garage is different etc, but generally going on an hourly rate, how much work would be needed?
Cheers.

You don't need to remove the head to do that repair work mate! That can be done in situ. Labour wise no more than 2hrs + parts cost for the helicoil or timesert. Timesert is the better of the 2, but also costs more.

Any garage or engineering shop should be able to do that. You need an airline blower to get rid of the swarf out the cylinder afterwards.

Yep you can do it in-situ, make sure the garage know what they're doing first tho and aren't just 'having a try'

It cost me about £40 ish if I remember right but it was through a mechanic mate so it shouldn't be too expensive

Lovely, cheers lads nice to have a bit of good news! The coilpack leads are possibly faulty as well, so another thing to check. First priority is getting the car up my drive, not just parked on the road down my hill, I'll be rescued by a tractor later!

I have had this done on a megane aswell. No problems at all, i used an engine rebuild place as i didnt fancy tackling it myself!

@NorthloopCup I know that timeserts are better as you state above but given the other issues my flamers engine has I'm happy to gamble on a helicoil kit, do you know what size I should be getting? Cheers

I think they're m14x1.25 mate, but I can't say 100%. @bloke will confirm.

Cheers, I had a bit of a look and thought it was M14 too so if 3 of us think that then its gotta be right!
