Why does my Silverado lifter burn so much oil?
Why does my Silverado lifter burn so much oil?
Engines with AFM use a high-volume oil pump. When you eliminate the AFM system, the extra oil is no longer needed. Excess oil will be pushed out of the pressure relief valve into the oil pan. This will spray oil on the bottom of the cylinder walls which can cause oil burning, especially in high-rpm engines.
Where is the injection pump on a 6.5L diesel?
There is a large round 15-way connector near the back of the intake manifold which joins the injection harness (which contains all the wires to the injection pump) to the main engine harness.

How can I tell if my car solenoid is working?
Unplug the solenoid and connect a test light across the two wires in the connector coming from the vehicle (NOT the side coming from the solenoid). Have someone crank the engine. If the test light lights proceed to the next step. If it does not light, then you will need to obtain a wiring diagram and trace the circuit.
What causes a Cummins lift pump to stop working?
Some customers will notice the truck “falling on its face” or flat lining with power as the pump simply cannot supply any more fuel. After time, the pump will just stop working due to being over stressed and constantly running at maximum output. And this is exactly what we will be testing for next, the health of the lift pump.
What causes a valve lifter to malfunction?
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. The VLOM consists of 4 electronically operated solenoids and is bolted to the top of the engine block beneath the intake manifold assembly.
Which is the best aftermarket lift pump for Cummins?
Our preferred brands of aftermarket lift pumps are FASS and AirDog, simply because they have options for stock to fully modified engines, offer filtration that is far superior to stock for increased protection, and come standard with a lifetime warranty.
