Aircraft X was base leg for an ILS approach into SNA. He was given a turn onto the localizer and cleared for the ILS approach. Apparently he was confused by the turn on and came back to me asking for the turn again. He now was crossing the localizer and approaching a 3700 feet MVA. I gave him a turn to intercept from the other side but his turn was not steep enough. He ended up in a 3700 feet MVA at 3000 feet. At Tustin [radar sector name] we used to have an area where we could descend below the MVA to the east. Where Aircraft X was a 3000 feet 'dump' area. It would really help out the airspace congestion if we could attack the ILS from both sides with the same MVA; instead if there's a blow through they are immediately in a higher MVA.
SCT TRACON Controller reported that an aircraft went through the localizer and ended up in a higher Minimum Vectoring Altitude then was issued.
