This bulletin applies to all Kia vehicles equipped with 2.4L Theta I & II engines. The correct OCV (oil control valve) must be matched with the proper cylinder head when servicing and/or replacing the cylinder head or the OCV.
It is possible to receive a superseding cylinder head that may require a different OCV. The technician must visually identify the geometry of the oil port of the new cylinder head and compare it to the old cylinder head. The superseded head has slotted oil ports, while the superseding head has circular oil ports.
If the cylinder head to be installed has circular oil ports, order the latest OCV, P/N 24355-2G500 intake or 24375-2G500 exhaust. If the oil ports are slotted, order the older OCV.
