  1. Using metal surface cleaner, clean all the sealing surfaces.
    NOTE
    If the lower intake manifold is not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
