As the title says...im concerned about my oil pressure in my 2009 avalanche (5.3 AFM). When its hot, 5w-30, I'm at 20-22 ish. Anything above idle...pressure jumps to 30. Anything above 1500rpm and I'm at 38-40. And above 2k, it goes to 45ish. Pressure will go up to 50ish when I get on it.

I removed the oil pressure sensor screen. Truck doesn't burn any oil more than normal. Should I be concerned? Is this just an oil pump swap?

 

That is normal for those engines.

The AFM/DoD system runs a lower oil pressure because there is an oil pressure relief valve in the oil pans filter housing. The max oil pressure you will see is about 60psi but typically 50ish at full throttle and your driving pressures are perfectly fine.

 

Yep^^^

Before I did my heads my oil pressure would drop to 19 or 20 hot idle, after its 31 or 33 hot idle and goes to 60 wot. The valley plate bleeds off oil pressure to feed the dod and amf parts.

 

appreciate the feedback guys...I'll quit worrying about it. It just caught my eye one day and I panicked!
