When the engines cold, the oil is at a steady 40 psi and slowly decreases as the engine warms up. When its it at normal temps and idling, it sits around 10 and gets real low sometimes.

If i go wot it'll never exceed 40..

the truck only has 35k on it.

anyone have any ideas??

 

Yikes! Is this a NBS or NNBS? Has the oil pan ever been removed?

Is it still under warranty?

 

damn! take it back!

 

failing oil pump? bad cam bearing? hard to say. tell us more about the truck.
