Could be a gasket, but if they said the manifold had to be replaced I suspect the manifold is cracked. Sometimes they are hard to see because of where the crack is located. You may have use a mirror to look between the manifold and the engine if nothing is apparent. Replaced one a couple of weeks ago on the driver's side. You could hear the leak but couldn't see anything. Initially thought it was a gasket. Once the manifold was off you could see the crack.
