An internal breather for removing oil from blow-by in an internal combustion engine is disclosed. The breather includes a breather cover having a breather cover drainback hole. The breather further includes a breather cover seal in sealed engagement with the breather cover, and the breather cover seal includes a breather cover seal drainback hole that is aligned with the breather cover drainback hole to create a drainback passage. A breather chamber is bounded on at least one end by the breather cover and the breather seal. A breather media is positioned within the breather chamber, the breather media for removing an amount of oil from the blow-by. The amount of oil removed from the blow-by can, during operation of the engine, be drawn through the drainback passage so as to exit the breather chamber, at least partially due to gravity, and at least partially using a gearing mechanism that is in operative association with a camshaft of the engine. Advantageously, the gearing mechanism, for example a helical gear, can be strategically positioned in-line with the drainback passage.
