If noise is with a cold engine and goes away hot, maybe infamous piston slap.

I am not sure what piston slap is but yesterday when it started the oil psi went over 80psi for a few mins then went to 40 when i put it into gear it went back to over 80 it fluxuated back and forth a couple of time and then staied at 40 at the time the lifter of valve noise was louder that normal i didnt use the truck this morning I called a repair shop to drop it off tonight when I started it to night outside temp was 70 it still had valve noise but nothing like yesterday i thought yesterday it was going to blow
