A couple things contribute to this. One is the crancase ventalation back into the intake track of the driovers side of the valev cover. The other is the EGR system (Exhaust Gas Recirculation) Which takes dirty exhaust gas and recirculated it under certain conditions. Such as idle and steady cruising throttle. It's done to improve emissions, but what it achgieves that matters to me is it gunks up the TB andintake manifold with the residue you are describing. When I have install my ported/polished intake manifold I will cap off the EGR system ( I already run two K&N breathers to keep gunk/hot air out of the intake track) so I don't dirty the manifold.
