If the gasket has failed there the blowby gases will produce that colour leakage. Get a length of windscreen washer sized hose and stick one end in your ear while listening for a air leak there at idle with engine both hot and cold. If it is leaking you should also see uneven idle or a delayed reduction in revs when you stop.

Remember to torque the nuts on the manifold up in a circular pattern like a head gasket and don't put the gasket on upside down and back to front (it will fit that way but will block of the injectors spray).
