Cummins 870 oil pressure
I have a couple issues that I’m dealing with on a Cummins 870 , I’m thinking they are possibly related .. first is on start up there’s no oil pressure for a good 5 seconds then it’s good and holds good pressure while driving and at idle , second is ive noticed air bubbles in the oil .. I’ve been a cat guy and first is my first isx I’ve had .. could it be pickup tube has a crack ?? Or oil pump loosing prime possibly ??or so mechanical oil pressure gauges just take a couple seconds to read Any help is appreciated
