Where is the PCV valve located on a 2002 Chevy Suburban with a 5.3 liter engine?

All GEN III GM egines (5.3L,6.0L,8.1L and LS1)have an internal PCV You do NOT change them....... well like most truck they are locted on top or back beside the maifold it will have a hose that goes to it one the passinger side at the top of the motor I am not positive, but I do not think it has a PCV valve. The Positive Crankcase Ventilation (PCV) valve on the 2002 Chevy Suburban with the 5.3 liter engine is located at the rear of the left valve cover-pull it out and check for vacuum with you finger.
