You’ll be fine in the reuse of the valley pan. Just don’t bend it up or kink it good.

On the newer design engines the intake manifold incorporates the valley pan, the part that seals the top of the block and heads. If the tunnel ram intake does not have the casting that seals the block and heads to keep oil in and debris out, then yes you need one.

A Valley pan or valley gasket is traditionally used to seal the lower intake manifold to the cylinder heads and engine. This gasket was vital because many of those engines have their coolant crossover built into the lower intake manifold and so the valley gasket was very much like a head gasket in design and function.

The purpose of a valley pan is to completely seal the lifter valley if you’re using an intake that has openings.

The LS6 engine valley cover is an excellent upgrade over the factory LS1 PCV system. This cover eliminates the two rear valve cover PCV hose connections as well as the PCV hose and PCV valve itself. The built-in, no-maintenance restrictor eliminates the need for a PCV valve.

Leave the knock sensors. No reason to delete them. It protects your motor from bad gas. AIR, EGR can go away, but leave the knocks sensors, like everyone else said, there is no performance loss and they will save your engine if you every get crap gas.

$895.00. We offer the INSTALLATION of Texas Speed & Performance AFM / DOD Delete Kit and the required Non AFM / DOD camshaft. – New Timing Chain Gasket, Water Pump Gasket, Etc. This is a very labor intensive upgrade.

AFM/DOD is General Motor’s technology that disables half the cylinders on a V8 engine during certain driving conditions to help improve fuel economy. The system is tuned to a specific camshaft — that is, the lobe profiles between AFM and non-AFM cylinders are different due to a different lash requirement.

We have found that most lifter faults are caused by oil pressure issues, or control issues. The AFM activation and deactivation is controlled by the Valve Lifter Oil Manifold or VLOM. Hydraulic lifters can collapse, with no oil cushion to dampen the pounding from the tappet or push rod.

Displacement on Demand

Ballpark $1600 labor seems common for DOD delete depending on how much “Extra” work they do while they’re at it.

Yes, you need to tune the truck to finish the AFM delete or the ECM will keep trying to engage AFM even though the mechanical aspect of the delete has been done.

You MUST turn off the AFM system using a Computer Programmer – OR – custom tuning. It is also recommended that you: Plug the pressure relief valve in the oil pan, and. Switch to a Standard-Volume Oil Pump.

Based on certain conditions and models, the MPG variation can be high or low. But to eliminate that possibility completely, disabling the AFM is indeed a better option for you. It’s an undeniable fact that the AFM is an appreciating tech to push fuel efficiency to a finer level.

Carmakers such as Cadillac, Mercedes-Benz and Lamborghini have toyed with cylinder deactivation on large engines. The concept is simple: use fewer cylinders under light loads to improve fuel economy.
