Hi, hope that I am allowed to ask this again, in this forum. I am having trouble determining which side the pcv valve is located. If you are standing in front of the car, and looking toward the passenger side(the left side), is the pcv valve located there? If pcv valve is on the passenger side, what is the part on the right side with a tube attached to it and the underside of the filter housing called? Oh yes and this item is also attached to the valve cover and the hole is about 1" diameter with a grommet attached also. Thanks for any responses.
