MCX/Viper/7000 w/oil separator drain relocation (stock separator tank location)
Typical separator drain relocation modifcation view
Shown in this view, is a Viper with the MCX air/oil separator tank drain relocation mod. In this case the separator drain was moved from the stock aluminum tube (Green arrow) to the engine side cover at the Red arrow. If your Viper or M/XF7000 has this modification, then the ROV valve is installed on the rear port of the separator tank as shown in the pictures contained in this photo album.
