    Also,

    Make sure you remove the orfice barb and do the drill mod. All 2013's have the larger holes now from the factory.

    Mistercoffee2: I would be interested in knowing how you removed the tube. I like to keep my car original so I made a half-hearted attempt at it but I was afraid of breaking something so I gave up. Did you use a heat gun or something & did you damage the tube?

    I removed the hose along with the PCV valve from the valve cover and the fitting from the intake, took it in the house, and yes, heat gunned it. The hose was very hard from years of heat and, as you can see in the photo, one end broke.

    I put the new hose on the PVC Valve and the intake fitting which is a better looking install but functions no better then cutting the hose..

    I Did not know that! I assume you refer to the orifice pictured here. Problem is the Service Manual does not say where it is located. Where is MOD documented?

    It is in the rear of the passenger side valve cover where the line from the top of the intake manifold snapped on. Grab it with a plyers at the base, twist and pull up and it pops right out. Then drill to 7/64" both the single top and 2 bottom holes, clean debris and seat back in fully and your good to go.
