Important AFM / VLOM Installation Notes — read before install

Fraser Engines has identified that many Active Fuel Management lifter failures are not due to defective lifters, but rather issues with oil pressure or oil control within the AFM system.

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, also known as the VLOM.

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

Installer Responsibility: When replacing AFM components, the installer must replace the OEM VLOM filter located under the oil pressure sender. The VLOM assembly should also be tested for proper operation or replaced as necessary.

Warranty Disclaimer: Any failure resulting from improper VLOM operation, restricted oil passages, or a contaminated or untested VLOM assembly will not be covered under warranty.

About This Product

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.
OBDII Tuner Required: Add a compatible tuner to your OBDII port to complete DOD / AFM delete operation.
Heavy-Duty Ready: Ideal for towing, hauling, high-mileage vehicles, and performance use.

Included Warranty Coverage

3 Years / Unlimited Miles — Parts & Labor

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

Important: A compatible tuner is required for proper DOD / AFM delete operation. The tuner must be installed through the vehicle’s OBDII port to ensure proper engine operation.

Optional No-Fault Warranty available at checkout — see options. Recommended bundles: Break-In Fluid and Installation Kit.

Tech Updates • Why Choose Fraser Advantage

Fraser Engine Tech Updates for the EcoTec3 6.2L (2014–2024)

The EcoTec3 6.2L GM V8 (Gen V; RPO L86/L87) powers premium Chevy, GMC, and Cadillac trucks/SUVs with class-leading torque, direct injection, and active technologies. While robust, these engines have a few well-known pain points. Fraser Engines addresses them through precision remanufacturing and targeted upgrades to improve durability, drivability, and long-term reliability.

AFM/DFM Lifters & Camshaft

Why? AFM (2014–2018) and DFM (2019+) lifters can collapse, damaging the cam and causing misfires.

Update: Fraser installs updated lifters and guides. For customers opting to eliminate cylinder deactivation, we offer a complete AFM/DFM delete: non-AFM lifters, matched camshaft, valley cover update, and tuning recommendations for stable 8-cylinder operation.

High-Pressure Fuel System (DI)

Why? The direct-injection HPFP and injectors are sensitive to wear and contamination; the cam-driven pump follower can show wear.

Update: HPFP and injectors are tested and replaced as required; cam lobe/follower inspected and addressed. Fuel rails/injector bores are ultrasonically cleaned; new Teflon-coated injector seals installed where applicable.

Intake Valve Carbon Control (DI)

Why? DI engines don’t wash intake valves with fuel, leading to carbon build-up and airflow loss.

Update: Heads and intake tracts are professionally cleaned; valve faces/seats are cut to spec. We add PCV/vent routing updates and provide service interval guidance (e.g., periodic induction clean) to help slow re-depositing.

Timing & VVT System

Why? Chain stretch, guide wear, or cam phaser noise can affect timing accuracy and idle quality.

Update: New heavy-duty timing chains, guides, tensioners, and an OE-spec or updated phaser. Cam/crank correlation is verified during build and final QA.

Lubrication Enhancements

Why? Variable-displacement oil pumps and tight DI tolerances demand consistent oil pressure; leaks from gaskets/seals are common with age.

Update: New or updated oil pump, precision-measured bearing clearances, and premium gaskets & seals (front/rear mains, pan, valve covers). Oil passages are hot-washed and brush-cleaned to ensure full flow.

Piston & Ring Package

Why? Wear or stuck oil rings can drive oil consumption and compression loss.

Update: Hypereutectic pistons with modern skirt coatings and upgraded ring packs restore ring seal, reduce blow-by, and stabilize oil usage.

Cylinder Head Reinforcement

Why? Thermal cycling can stress seats/guides and deck flatness.

Update: Heads are pressure-tested, resurfaced, and assembled with new valve guides/seals and precision three-angle seat work. Deck surfaces are finished to MLS-gasket spec.

Cooling System Integrity

Why? Overheating accelerates wear and can compromise head gaskets.

Update: Block and head surfaces are machined for optimal gasket clamp; cooling passages are de-scaled and flushed. We recommend OE-quality thermostats/water pumps at install.

Rotating Assembly Balance

Why? Imbalance increases NVH and bearing wear.

Update: Crank, rods, and pistons are dynamically balanced; run-out checked; final assembly blueprinted to tight tolerances.

PCV / Valley Cover & Vacuum Pump

Why? Oil ingestion via PCV can foul plugs; some engines show vacuum pump seepage.

Update: Revised PCV baffling/valley cover strategy to curb ingestion; vacuum pump inspected and re-sealed or replaced as needed.

Why Choose Fraser Engines for Your EcoTec3 6.2L

Critical fixes implemented

AFM/DFM lifter strategy, timing/phaser integrity, DI carbon control, lubrication and sealing.

Better-than-OEM process

Precision machining, blueprint assembly, and rigorous oil-pressure, compression, and leak-down verification.

Warranty options

Strong coverage with No-Fault add-ons available for maximum peace of mind.

Real support

Pre-install guidance and U.S.-based tech assistance.

Installation Recommendations

ECM Calibration

Required whenever AFM/DFM is deleted; Fraser supplies tuning guidance for correct fueling, spark, and diagnostics.

Engine Oil

Use Dexos-approved full synthetic per OE spec (commonly 0W-20 on L86/L87).

Fuel & Maintenance

Premium fuel recommended for best performance in many trims; follow Fraser’s break-in sheet and keep early oil changes.

Best Practices

Replace plugs/coils as needed, smoke-test for intake leaks, verify coolant system operation, and update belt-drive components as appropriate.
