I'm sure you're aware of this however for clarity, and to understand where my question comes from, the one used on NA engines (ford pn#E3TZ-6A665-A or IH pn# 1805319C1) has a fitting/ pipe tip for inserting into the valley pan as well as a hole where it presses against the intake manifold. The CDR used on turbo engines sits on the driver side valve cover and has a pipe tip at both locations. One fits into the valve cover while the other has a hose attached connecting to the air filter assy. I assumed since the parts appear different, they have different pn#'s. The one I received with this (used) turbo seems to be leaking and I was hoping to purchase a new one. I'm not opposed to a RDT and maybe we can discuss this when I visit you on Thursday?
