At times like this I have had a local machine shop machine me a stud with say m10 at one end and m8 the other assuming an original m8. Then drill and tap the original hole to m10 and put that side of the stud in. I have more luck with this repair than thread inserts.

After some ****ing about I can't get the other half out. So it seems like head will have to come off for **** sakes.

Ok take your time. Can you post a picture of exactly what's went wrong?

I did this amazing drawing here The black bit is original hole in full length, and red bit is the second half (first half came out) of the thread insert that's stuck in there







I can't get access with the drill (even if I take downpipe off). I tried using bolt extractor without any luck

It's looking dodgy..
I'm thinking a right-angle drill with one of those left-handed drill bits. You'll still need to get a new insert fitted though..

[diesel des]

Yep try an angle drill

Thanks John, didn't think of that 90 degree attachment One will be on order soon and I really hope it works.

I will also visit my local engineering company and see if they can make me M12 to M8 stud as Described suggested, as making thread in the head is best way.

Haven't seen these before I guess this would be best for future as I could use M8 studs

If you could check that would be great mate

Just to check, manifold studs are M8x35? Asking because the ones I've removed are M8x50?

I'd be careful doing it on the car as I'm not sure where the water ways etc are in the head. If you can best bet would be to have head off and have it fixed so an accurate drilling and rethread can be done

Hi Janis, have you got any further with your problem?

[hunker7]

Car has been sitting for couple of weeks and will for another couple of weeks. I've bought the 90 degree drill attachment, but even then I will have to remove the downpipe to fix the thread
