Spacer equipped to spray oil for valvetrain in an engine system

A spacer for a valvetrain in an engine system, the spacer comprising:

• a spacer body including:
• a first axial end,
• a second axial end,
• a cylindrical outer surface,
• a cylindrical inner surface defining a through-bore extending from the first axial end to the second axial end along a spacer axis, and
• an oil feed inlet defined in the inner surface;
• an orientation element extending outwardly from the outer surface along an orientation axis which is transverse to the spacer axis, the orientation element including an inner orientation surface and an outer orientation surface;
• and
• an oil application structure extending outwardly from the outer surface along a structure axis which is transverse to the spacer axis and the orientation axis, the oil application structure including a plurality of oil spray channels each terminating at a respective oil spray outlet fluidly connected to the oil feed inlet.
