Does lifter noise go away?
Lifter tick can happen due to dirt in your engine oil, low engine oil levels, improper lifter spacing, or overall faulty lifters. You can get rid of the lifter ticking sound by changing the engine oil, clean the lifter with oil additives, adjust the lifter spacing, and in rare cases replace the entire lifter.
Why does my GM Truck make a noise when I start it up?

Why does my Vortec engine make a ticking noise when first started?
Keep in mind that heavier oils are slower to lubricate when the motor is first started, particularly on a cold start, which can lead to additional wear and tear on the engine. Running engine cleaner through the engine can help remove carbon deposits that can contribute to ticking at start-up.

What causes a loud cold start knock noise?
I don’t think there is anything (maybe a rebuild) that will fix the piston slap. The lifter noise is usually dirt and, or wear, that lets the lifter “bleed down”. Sometimes as @ Conlan Rose suggested, it might be a slow to build oil pressure issue, that is caused by a dirty oil filter, sometimes it’s clogged oil passages.
