Genuine GM Parts 12697806 - Early Gen V LT VLOM

Description

The GM Genuine Parts 12697806 Engine Valve Lifter Oil Manifold is an authentic factory Original Equipment (OE) cast aluminum engine valley cover assembly engineered specifically for General Motors Gen V 5.3L and 6.2L Direct Injection V8 engines (L83, L86, LT1). Positioned in the engine block valley beneath the intake manifold, the VLOM houses the integrated electro-hydraulic solenoids, internal oil passages, and electrical connectors responsible for routing pressurized oil to the collapsing Active Fuel Management (AFM / Displacement on Demand) lifters. Replacing a clogged or failed VLOM assembly is critical to clearing low oil pressure diagnostic trouble codes (such as DTC P0521 or P06DD) and eliminating AFM-related lifter ticking issues.
