Oil Control Orifice is a component designed to regulate the oil flow to the cylinder head. While engine oil is typically directed to the cylinder head, the orifice is utilized in high-speed situations to restrict and optimize the supply of oil, ensuring that the right amount reaches the cylinder block. This controlled oil flow is crucial for providing adequate lubrication between bearings and main/rod journals, thereby preventing potential engine issues. The use of our oil control orifice is particularly recommended for demanding driving conditions, where the engine is subjected to increased stress and heat. When installing, gently tap the orifice into place about 1-2mm behind the mounting surface to avoid interference with the spool valve.
