Engine head cover assembly having an integrated oil separator and a removable cover
A head cover assembly for covering a crankcase of an internal combustion engine includes a head cover, a removable cover, a guide, and an integral oil separator. The oil separator includes a labyrinth that defines a flow path that separates oil from crankcase gases passing therethrough. The guide includes a tubular body presenting a passage for which manifold vacuum may draw crankcase gas from the oil separator. The cover includes an aperture. The tubular body is disposed through the aperture such that the outer tube surface is spaced apart from the inner edge of the aperture to define a gap in which separated oil may drain back into the engine for recycling.
