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.
Oil pressure alone is not a good indicator. Tuning your ECM is required to turn off AFM/DOD.
The hydraulic lifter in a car's engine uses oil pressure to adjust a plunger and take up all the clearance in the valve train. This helps to ensure less engine noise and longer reliability, due to less wear and tear.
Hydraulic lifters can begin to fail through normal use of a vehicle. After several years of running the engine of your vehicle, the hydraulic lifters within the valves can become laden with sludge, and other contaminants in the valve, that they start to wear out. New hydraulic lifters can make a tremendous difference in the way that a vehicle runs as well as how the engine sounds. The head gasket is the key component of the engine. It is compressed between the engine block and the cylinder head.The head gasket seals in the internal combustion process to make sure maximum compression is achieved and also keeps coolant and oil from mixing together as the two fluids travel from the engine block to the cylinder head. Therefore the cylinder head gasket, and lifters are an important part of your engine. They should always be in perfect condition and should be maintained properly.
