In a word, no! They were cheap casts and crack with continual heating and cooling cycles. Either find an uncracked one from a breaker or take it off and get it tig welded.

common fault with a lot of cars :y

Nothing wrong with manifold on mine of 151k miles, nor Father T's of 110k miles.
Like I said on the other thread (sorry not had chance to reply to your PM) But that gasket does not look multi layer. When did a 2.2 HG the exhaust manifold gasket was multi-layer, wonder if its had work done on it, and its not been re-fitted correctly / torqued up?
The cylinder gasket does not need to be multi layer, but advice I had was to re-use the exhaust one....

I can offer no help other than the above, but .. the first thought I had when I read the thread title was "cheese Gromit!" :-X

As Welung says it's a common problem on some 2.2 manifolds. Mine went in the same place, replaced with a new one. Can be difficult to weld, I was told. Got mine off ebay, gen GM manifold complete with muti layer gasket, studs and nuts.

when welding cast, you need to get the whole area [size=12]HOT[/size] otherwise as it all cools down you often end up with a nice new crack along side the weld. As far as TIG welding, I'm not sure :-/ I've always used a MMA/stick set when welding cast

either stick or braze, not tig :y
