I have recently purchased a 2004 LB7 CCFB dually. I'm just curious what the oil pressure is at idle and also what the average engine temperature should be?

Mine is around 20- 25 at idle usually. The pressure jumps alot off idle because there are oil ports spraying up the cylinders cooling the bottom of the pistons once the rpms climb.
There are 2 thermostats in parallel, one at 180F and one at 185F, so somewhere between there and 200F is average depending on outside air temp.
