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.
75 is up there. It sounds like your pressure relief valve is not working since that could cause some oil leaks at your oil filter. Before you got too deep in the engine though, I'd replace the oil pressure sender.
Lol dually noted. Where is the relief valve? How its it to change?
It's part of the oil pump. Doesn't sound like that's your problem since you have adequate pressure. I would put in a different brand oil filter and replace the sending unit. Ten minutes of work and less then $30.00 for peace of mind.
Cruising home today at normal temp I was running around 50-60psi. Idk lol its running fine. Other than I noticed I think my f'n water pump is starting to seep. Thats just awesome when its in the 30s and 40s here now
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
