Cracked exhaust manifold, options?
Not having the greatest time of at the moment! I've currently got the engine in bits due to a stripped cam belt. Got the head back today and stuck it on the dining room table (mrs was very chuffed) ready to start putting stuff back on, only to find a crack on the flange that sits against the turbo. Closer inspection shows it is also cracked on the inside where the two chambers come together just before it exits. So far the cracks haven't made it to the outside, it looks like when I have unbolted it tension has been released and the flange has twisted slightly causing the crack. It looks like when it's bolted back down it would pull the crack back together.
Obviously it's much easier to sort this now rather than gamble only to have to swap it with the head on so what are the options. Is this one of the cases where a performance upgrade is cheaper than standard or should I start scouring the scrapyards?
