I've just confirmed the reason for the blowing exhaust manifold on my 2.2 

Both upper and lower front studs have sheared. The others seem intact but didn't put too much weight on them in case they went and put me off the road.

I dont fancy nor have the time for a head-off job so now looking for a decent local engineers to do the job.

Never mind.

why dont you just get a stud extractor, all you need to do is take of the manifold off, pull the exhaust rubbers off, push exhaust down, then drill the centers of the studs and extract the studs with the extrator remove the studs, there is just enuf space to drill the holes. my take awile but easy to do.

Cheers.

Yep, I'm more than happy to do this but can't see that there's enough room to get a drill in. Would save £££££s if I could. Do you know of a suitable drill or attachment that might work?

Thanks Rob/Rusty.

I had in fact looked at the attachment from Machine mart on Sunday. I guess there will be enough room to get this in if I remove the dipstick tube.

I'll measure up carefully and give it a go.

Has anyone used this technique before with any success?

As a matter of interest regarding the studs that remain intact (if any): Should I leave them be and reuse them or take them out and replace with new ones?

Cheers.

I've done them with a right angle attachment, studs towards the rear are tight but this can be overcome quite easily. I jacked the front passenger corner up, took out the bolts from the passenger side engine mount, put an axle stand with a chunk of wood under the sump and lowered the car down bit by bit until there was room to get the drill in

What you want to be really careful and methodical about is getting a good centrepunch mark right in the centre of the broken off stud.  A good square hit with your hammer on the punch once you're sure it's central will hopefully ensure that your drill goes right down the middle. The impact may also loosen the corrosion that is holding it tight.

If you go off-centre with your drilling, which is very easy to do, you'll have little chance of success with an easy-out.

Excellent point! My punch is only about an inch long, my mate turned it down on his lathe for just this job

the way we use to drill snapped studs was small drill then go up drill size usuallay before you got to the correct size the old stud normally had come out and then just run a tap up to clean up (m8) loads o grease then fit new studs with loads copperslip.

Thanks for all the advice, all most welcome.

I don't know what the final score on the studs is yet, only the two front are gone so far but I'll find out sure enough when I start undoing them.

I'll pass on the anatomical modifications thanks!
