I think it would be worth doing a 'how to' on the maintenance guide!!

I will investigate my manifold this week but from what everyone describes I will expect the worst!!

At least you don't have to remove the head though, not just from the cost and time aspect but when your engine is in perfect condition and low mileage (28k), seems sacrilege to remove the head!!

Apparently, after speaking to my local Vauxhall dealer, this is a very common problem and affects other models as well (mainly Vectras).

TD  - you will have to keep us informed of progress!!

Mine isnt on 28k....yours might be  :-/ ....mines done 92k now

Oh and should have added.....this is the 2nd time ive had exhaust manifold probs on my omega.

Both Veccies i have......one has done nearly 200k...other has done 90k....and no exhaust manifold probs with them....so dont think your vx dealer is telling you correctly!

Yes - sorry bit confusing mine has only done 28k!!

Completely pointless fitting a new gasket mate, until you've got the existing two snapped studs sorted out

It would be a waste of time and a gasket

Unfortunately, if you've got 2 snapped studs, you need to address that before you can fit a new gasket

Else it'll always be blowing.

Sorry

Apparently the two snapped studs appear to have been glued in (well at least one of them! the other has disapeared) And have been glued in for quite a while. I have been told a new gasket might hold for a few 10k miles before it goes again.

Ive seen this before, I bought a 2.0 which came with a brand new exhaust and receipt from quick fit which included a charge for replacing the exhaust manifold gasket, a few weeks later there was a broken stud and nut on the drive, it had been stuck in with body filler.

Interesting.....

When I once asked quick fit to do a manifold (needless to say years ago) - they wouldn't touch it - they will only do downpipe backwards, for fear of breaking the head and not having the skills to fix it!

By far the easiet way of locating the centre of the stud is to have a machine shop , or a friend who is a machinist, make up or turn a metal dowl / pin that fits snuggly into the bolt hole in the manifold !
Have a 2 or 3mm hole machined down the centre of this dowl/pin .

Leave manifold in situ, place dowl/pin in manfold bolt hole ( obviously over the broken stud/studs) and drill down centre of pin/dowl with pilot drill.

When all broken studs are piloted remove manifold and hey presto broken studs with exact centred pilot holes  

As already WARNED , dint drill too deeply or you may strike oil  
Measure a new stud to estimate the depth of the broken stud in head ! You can then mark the drill being used with tipex or similar with the stud depth !

Sorry i havent been round lately on this board, Omega is running like a dream, NOTHING going wrong for ages now

The manifold - downpipe had some of the bolt holes through-drilled and nuts fitted, I guess the original bolts sheared off so they tried removing the manifold to drill out the bolts only to have the manifold-head studs shear so the job was getting bigger and bigger. When I came to repair it I couldnt stop the nuts spinning so had to remove manifold and downpipe as one piece, the manifold was cracked which was causing the blowing noise.
