Small Air pipe

Hi, Does anybody know with the K series Rover 216 engine, the small air pipe that comes from the rear of the engine block on the right hand side.

The geeza who I bought mine off snapped that off and i cannot get it to fix back on at all air tight, so I'm thinking of replacing the whole thing as the screw thread is snapped off within the unit it'self.


If anybody can remotely understand what i have just tried to explain, then could you tell me if it is all a part of the rocker cover or if that is a seperate part?


cheers
