Oil press. ???
Ok so im gonna ask this as stupid as it may be. When i first start my 5.2 at a dead cold start, my oil pressure is around 70psi or so. Today it was near freezing outside and when it first ran at idle the gauge fluctuated back and forth a bit from 20psi-75psi then leveled out at 65psi after about 3 mins. On any typical day it will idle cold at 70psi then as it warms up it will drop to midway when driving on interstate and at a redlight its reading about 30psi or so. Normal? I know some oil pressure is better than none lol.

Both of the 5.2s and the 5.9 run at about ~45 to ~60psi at operating temp with engine speed above idle and with engine cold at idle, oil pressure is never less than ~30psi at operating temp., idling... Know what you mean, hurts even more when you bust a knuckle when your hands are cold... But, at least the pain is only momentary, for me anyway...

Yup I've got around 30psi at idle. Guess everything is fine. Will use a wix filter next time for sure. Ive got 206k on the ol girl now. Having trans rebuilt and bulletproofed next month and also need need a new.control arm kit too. Looking at the IRO arms. Im running 4.5" suspension now. But plan to add some 2" bb to it. Motor seems strong. After I replace the water pump I'm hoping all my leaks subside
