I need to change my PCV valve on the Gen 2 4.0L. I have located the valve on the back of the driver side valve cover. It's like the guy from Where's Waldo planned on where to put that thing. Hose and plug simple enough. Question is the new valve looks to have a tooth on each side that would keep you from just spinning the old valve out. Any experience here in changing it? Will it just spin out or is there something more devious going on here?
