First, nothing you have done has anything to do with valve tappet noise. What is your oil pressure? Have you positively identified the noise as a lifter (tappet), OR COULD IT BE AN ENGINE BERARING OR WRISTPIN? Other than tearing it down and replacing lifters, rockers or pushrods or possibly even the cam, if oil pressure is good, change the oil and put a quart of Marvel oil in there. If that does not clear it up in a few days, you will have to go inside the engine. You likely have over 160k on that engine...consider using a replacement. Get an older tech to listen to it...it takes years to be able to differentiate between different component noises with any accuracy.
Personally, without hearing it myself, I'm betting it's a rod knock.

Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.
