06 Chevy 2500 hd oil pressure low on cold mornings
I have a 06 chevy silverado 6.0 on start up the oil pressure is low 8-10 oil pressure and after a few minutes it starts to raise up. What could be causing this. It does this more often on cold days than on warm days. Any help at all would be appreciated.
I use 5w30 oil and the last time i got it changed I used synthetic oil and it didn't change it. I'm tearing it down and putting a oil pump in it. I figured it wouldn't hurt with it having 296000 miles on it.
