    basically when you drive the truck, and drive it hard (make it whine ;)) when you let off the gas pedal, oil gets sucked up through the PCV system and soaks the intake tract and COATS the intercooler in oil, reducing performance, reducing the effective octane rating of the gas, and basically making your nice truck run worse than it could.

    I run the L&S separator on my truck, and fully recommend it to anyone else

    L&S Automotive Performance - Oil Separator Article

    I would recommend pulling and cleaning out everything above the intercooler (pull the supercharger) to get everything nice and clean when you install a separator.

    I just bypassed my system. Some think it's a great idea others do not. I know I have zero oil now and my truck runs just fine.
