i have a 1997-nissan pickup,2.4liter automatic .i can not find the pcv valve.i have look all over the engine.do i need to take the valve cover off.
My son had the same engine in his 240sx and the valve was in the valve cover as is typical…the 2.4 was a truck engine that had a propensity to break up the plastic chain guides and plug EGR valves
What it looks like: http://www.autozone.com/N,16400030/shopping/partTypeResultSet.htm It screws into the intake manifold.
