That description along with availability of a PCV valve for the LGX, part number 12666420, seems to imply the IM is drawing foul side air from the center of the V that is not readily seen.
Does anyone know where this PCV valve is located? |
that particular "pcv valve" is located at the front of the engine on the clean side area... it connects to the passenger side of the intake on the arm and then to the tops of both cylinder head tops.
the dirty side of the PCV valve is actually coming from the rear with a long clip on style connector and then attaches to the intake tube on the driver side via this rubber grommet gimmick. there's not actual check valve inside the dirty side PCV hose itself, but there is a valve inside the back of the block.
