5.3 Tick/Knock?

[JPVortex]

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.

Your oil pressure numbers are fine. General rule of thumb is 10psi for every 1000 rpm. We of course get much more than that at idle. Lack of oil changes (dirty oil) can cause crap buildup in your oil passages and in your lifter bodies which can cause them to stick. That crap in your oil will also eventually end up embedded into your cam, rod and main bearings if the problem is severe enough.
