Genuine GM Parts 12709315 - LV3 4.3L V6 Valve Lifter Oil Manifold (VLOM)

Description

The GM Genuine Parts 12709315 Valve Lifter Oil Manifold (VLOM) is an authentic factory Original Equipment (OE) aluminum valley cover and electro-hydraulic solenoid assembly engineered specifically for GM Gen V 4.3L EcoTec3 V6 engines (LV3) equipped with Active Fuel Management (AFM / Displacement on Demand). Mounted in the engine valley beneath the intake manifold, the VLOM houses the internal oil control solenoids that direct high-pressure oil to the collapsing AFM lifters to activate and deactivate cylinders. Replacing a failed or clogged VLOM assembly is critical to resolving AFM system hydraulic pressure faults, lifter ticking, or low-pressure oil delivery issues.
