twocoltbob Posted December 16, 2015 Report Share Posted December 16, 2015 I now have 114,000 MILES ON MY 2005 ESCALADE and it is still running great. I would like to change the PCV valve but do not know where it is located. Can anyone give me some help or post a photo? Thank you in advance.

Bruce Nunnally Posted December 17, 2015 Report Share Posted December 17, 2015 I believe it is in driver's side valve cover. However, a 2005 should use a fixed orifice pcv which does not require maintenance replacement.
