A method for increasing wear resistance of a turbocharger includes exposing at least a bearing surface of a center housing of the turbocharger to a gas nitrocarburizing process or a plasma nitrocarburizing process, thereby forming a conversion coating impregnated onto the at least the bearing surface.

Turbocharger housing with a conversion coating and methods of making the conversion coating

A crankcase ventilation system is provided. The crankcase ventilation system is fluidly coupled between an engine block assembly and an axially extending air inlet adapter. A crankcase vent nozzle is provided as one aspect of the system and extends into the air inlet adapter. The crankcase vent nozzle has a leading edge portion and a trailing edge portion extending radially into an axially extending flow path in the air inlet adapter. The trailing edge portion extending further into the flow path than the leading edge portion.
