part info
cn someone please tell me what the thing is that goes into the valve cover by the oil cap? it has a hose that runs from it to air box its a black circular thing that just plugs into valve cover. in this pic, its the black thing behind oil cap
It is your secondary or High RPM PCV system. At low RPMs vacuumed keeps your crankcase scavenged. At high RPMs your vacuum drops so they need to pick it up from the air box. The breather is the little filter looking thing in the airbox that the black pipe hooks too.
