Hi guys, after posting up my vid on here and seeking advise from elsewhere, figured that the clicking sound from engine that increased with rpm was down to leak from exhaust manifold, so changed the gasket and studs but noise is still there.
So now I've been told it could be a crack in the manifold. This may sound stupid but for this do I just need to replace the exhaust manifold or are any other parts required?
Also I've seen a 6 branch manifold locally, what are the advantages of this over the standard 280zx exhaust manifold?
