Firstly, take the Manifold off and change all of the stud's so there are no problem's in the future.

Secondly, oxi & ceterlin(sp) if the stud is pertrooding(sp)

or if they are'nt pertrooding then you'll have to drill them out mate.

Good luck

if u got a welder , grind old bolt shank down to a point and weld it on to broken one then when cool , undo easyer than drilling right out

this is a head off job really as the only room to drill out in situ is the one at the top right at the front!

Kack job!

Sounds like a Tech Help query to me.

Please post in the appropriate forums.

If you can get hold of a right angled drill and use a left handed drill bit, "I'm not takin the p**s Snap-On do them" that way as you drill it the force is undoing the stud not tightening it, if that fails try the weld a bolt head on as the heat transfer also helps to loosen the stud.

Got this problem myself, gonna try the weld method first.

But just a thought, instead of welding a washer etc to the broken stud to remove it, ( is this always 100% effective ) could you weld a smalled threaded stud on and just use that to bolt the manifold on??

How much are studs torqued up?

I had two snapped at the front and two at the back, so I had to sort it out really. I took the car with no manifold on!!!!!! down to the local agricultral engineers who fix all our tractors, the guy got two out with Oxy Acetelene and a nut as they were protruding. The other two he got out by drilling and then using the torch and a stud extractor, the rear one he couldn't drill straight so he drilled it a size bigger (M10?? or was it M8) and put a larger stud in and drilled my manifold to suit. Cost Ԛ£50 in total I think, bargin.

Take the greatest care not to shear any more when you remove the manifold. Split or grind the nuts off if neccessary.
When you reassemble, copper grease is your friend.
