On initial climb out [at] about 5;000 feet we received a LVL 3 alert (number 2 manifold failure).  We retarded number 2 throttle to idle; referenced the QRH; and complied with land at nearest suitable airport.  We told Departure we had to return to [departure airport]. They gave us vectors to [the] runway and we landed uneventfully. Captain was pilot monitoring and First Officer (FO) was pilot flying.  We had very good crew coordination and FO flew a nice approach and landing with all QRH and appropriate checklists completed.Number 2 air system manifold failureThese things happen (this airplane is [over 40] years old). You just have to learn to deal with them and do the required procedures in the event of a problem.
