Aero Engines Inc has identified that many Active Fuel Management (AFM) lifter failures are not due to defective parts, but rather issues with oil pressure or oil control within the system. Our testing has shown that a majority of returned AFM lifters function properly when evaluated under correct operating conditions.

The AFM system operates within a normal oil pressure range of 27 PSI to 66 PSI. Activation and deactivation of AFM lifters are controlled by the Valve Lifter Oil Manifold (VLOM), which directs pressurized oil to the AFM lifters when cylinder deactivation is commanded and stops that flow to reactivate the cylinders.

In several warranty cases, AFM lifters have been found stuck in a compressed position. This condition is often caused by the VLOM commanding activation or deactivation at the wrong point in the camshaft rotation, such as during the ramp or at the lobe peak, rather than a fault within the lifter itself.

Core Policy: This unit requires a returnable core. Free pickup is arranged by Aero Engines Inc.

Aero Engines Inc has identified that many Active Fuel Management (AFM) lifter failures are not caused by defective lifters, but rather improper oil pressure or incorrect oil control within the system.

The AFM system operates between 27 PSI and 66 PSI and is controlled by the Valve Lifter Oil Manifold (VLOM), which directs oil pressure to activate or deactivate lifters.

Failures often occur when the VLOM commands activation at the wrong camshaft position, causing lifters to become stuck, this is not a defect in the lifter itself.

A 6.2L DOD Delete Engine is a modified version of the original 6.2L GM engine where the Displacement on Demand system, also known as Active Fuel Management, has been removed. This improves long-term durability by eliminating the frequent cylinder activation and deactivation that can contribute to premature lifter, camshaft, and valvetrain wear.

• Improved Durability: Eliminates common DOD-related lifter and camshaft failures.
• Consistent Performance: All cylinders remain active for smoother full-time V8 power.
• Custom Tuning Required: ECM must be programmed to remove DOD settings for proper operation.
• Heavy-Duty Ready: Ideal for towing, hauling, high-mileage vehicles, and performance use.
