What make are they? OEM? What turbo you have on it? Are the nuts torqued properly?

Have you tried making the holes in the manifold wider to take the strain away?

I noticed when mine cracked in the middle that the two centre bolts were hard against the holes in the manifold.

So far so good on the new manifold worth a try?

age of the manifold and nothing more

snapped engine mounts wont cause it as the downpipe is bolted to the gearbox so its solid and also the reason for rubber exhaust mounts

Wrong they will, excess engine move movement will crack a manifold, as I found out, the skyline exhaust is a CRAP design with no flexi join in the downpipe.

Best way to stop a manifold cracking is keeping it cool, take the heat shield off and like the other say elongate the bolt holes, it'll help loads and make sure its pan flat also that no engine or gearbox mounts are gone.
