This kit include the valley pan gaskets for engines with Active Fuel Management (AFM.) system, and without Active Fuel Management (AFM). However the plastic AFM valley pan gasket in this set only use to replace the perimeter seal only. This kit DOES NOT INCLUDE the complete valley pan gasket that use to service Displacement-On-Demand solenoids. Engines with AFM use a special camshaft, a high-volume oil pump, and a pressure relief valve in the oil pan. AFM lifters fail when feed oil to the lifter is low or mistimed. GM has released an updated VLOM (Valve Lifter Oil Manifold) # 12571609 to help address this problem. Install new VLOM is highly recommended. Anything that affects oil pressure to the AFM lifters will cause AFM lifter failures: includes failed oil pump, restricted oil pickup, leaking cam retainer plate or anything that reduces oil flow to the VLOM. Oil pressure alone is not a good indicator. Tuning your ECM is required to turn off AFM/DOD.
