Cat / Cummins oil pressure?
Ive ran a lot of cats and this is my first cummins, When i start the cummins in the cold say 35-40 degrees the oil pressure barely hits 50 at idle now a cat will go to about 80lbs at this temp at idle, is this normal for a 2002-2003 cummins ISX ?

My 2004 ISX runs about 50 psi at idle on a cold day, and around 40 psi when going down the road. When the truck is warm, it will sit at around 35-40 psi at idle.
