If it is a lifter tick could my current oil pressure cause this?


I know 40psi idle is like the norm for these trucks. My truck on cold start idle has around 45-50psi. When warm idling it has around 35psi. When I am cruising at 1500 rpm warm it has around 45psi. And finally at around 4000rpm it has like 60psi.

Would this be too low? I feel like it’s not but just looking for a second opinion.
