I have a 96 4runner that recently needed the PCV valve changed. The new grommet was so tight and the space to get your hand on the valve so small that I could not get the valve into the valve cover. I whipped up this "thingy" the help insert the PCV valve and allow you to get enough leverage the easily push it into the valve cover without breaking the new valve.I i rounded the top to make it easier on your hand and the inside is stepped to fit the PCV valve for the Toyota 5VZE 3.4 motor.
