This is the emission smog valve for many different GM vehicles from 1984-1985. This is a brand new, factory OEM, genuine GM part, manufactured by ACDelco, still in the original box. The box is in really rough shape. This part is brand new, although there is a little surface rust on a couple of the threaded connections, which shouldn't affect the functions at all. This is for 2.8L V6 engines and mounts on the right bank.

GM part # 22048268
