Whats the recommended dare I go to Vx to get it done or could I do it.
Been on my list of things to do for a while.
Although I am not getting any kind of popping noises I would feel much happier with all the studs in place.
If I can do it can anyone suggest the right tool for the job.
Any responses would be most appreciated
Cheers in advance

Think helicoil's the way to go for sure.
Just need to make sure you drill out the original bolthole nice and straight.

Dare I say it but there's a long thread on this on MIG Web forum.
Although I think MarkDTM has the best solution of using the manifold itself as a drill guide (with a sleeve inside the hole to protect the manifold).
Hang on I'm talking rubbish - you're not trying to remove a broken stud - duhh!

Never heard of HELICOIL before how does this work out of curiosity.

Well basically it's a thread that you insert into a non threaded hole then screw a suitably sized bolt into it.
You'll be able to buy a set from your local tool suppliers. Some places used to do a sale or return service where you could take the kit away and return the ones you didn't use because a full set can be expensive.
Having said that, I just searched www.frost.co.uk and they sell a set for £25!! Bargain!!
See it here (http://www.frost.co.uk/item_Detail.asp?productID=9009&frostProductName=M8%20x%201.25mm%20Helicoil%20Kit)
Y'just need to make sure you get the right size. Look at the variations further down the page.

Just had mine done on a 2.0lt.Was getting the ticking when cold then it progressed to doing it constantly. I started the job myself ,found two sheared studs ,nos 1 and 2 front top and bottom, no thread protruding from head on one so I quickly realised that I would not be able to get into the stud with any drill I have ( very limited space between engine and inner wing)and after being told that one of the studs is VERY close to the water jacket ,I built it back up and gave it to my local (45 miles away ) GM /Opel dealer over here in Ireland.They did them both in a day fitted the modified gasket,correctly welded up the 3 inch crack that was found on the manifold after kindly e mailing me a photo of the unit, flushed out the cooling system and topped up with fresh anti freeze.
Charged me 450 euro which is approx £310.
Interestingly a whirring best described as plastic cogs meshing has disapeared from the engine which was always there since I bought it 12,000 miles ago. It runs turbine smooth now.

I did mine a while back and i needed to remove x3 studs in total, x1 at the top and x2 at the bottom. I used a handheld mains driven mini drill for the top one and used a flexible attachment on the end of the drill for the bottow two.
This method worked a treat and easily prepared a straight hole inside the stud, ready for a 'reverse drill bit' extraction. Although it wasn't a walk in the park, it still needed a bit of thought and elbow grease!
Check out this ebay auction to see what i used...

Cheers for the response Omega2000w,
Funnily enough my dad suggested using one of these.
Cheers for the suggestion will be going the helicoil route and flexi drill.
Come payday thats when I shall give it ago at sorting it.
Was thinking of going to Vx but I remember someone over on the other site had it done and they drilled to far and into an oil pocket or something.
Cheers for all the responses :)
