You have to do a little digging but TM 9-2320-289-34, Chapter 2, section 34 has the pressures listed. This is using the STE/ICE diagnostic unit.

idle - 10psi or above
2000rpm - 40psi or above


From the TM 9-2815-237-34 6.2L/6.5L Diesel Engine Repair Manual

Section 2-34, the following is listed

Underload - 40-50psi
Idle - 10psi minimum


Cold will always be higher than hot.

You can alway look in the Chilton or Haynes manuals and find the same information.

If it doesn't turn up, even with a search, chances are its in the TM
