Abstract: A spacer for a valvetrain in an engine system includes a spacer body defining a spacer axis and including a through-bore extending from a first axial end to a second axial end, an outer arcuate surface, and an inner arcuate surface having an oil feed inlet. The spacer further includes an orientation element extending from the spacer body and defining an orientation axis transverse to the spacer axis, and including an inner orientation surface and an outer orientation surface. The spacer further includes an oil application structure defining a structure axis oriented transverse to both the spacer axis and the orientation axis, and including a plurality of oil spray channels, each respective one of the plurality of oil spray channels including an oil outlet at a termination point and being fluidly connected to the oil feed inlet.
