A lubrication system for an internal combustion engine having a pressure regulator to optimize oil flow through an engine to increase engine efficiency. The lubrication system includes an engine driven oil pump connected to supply pressurized oil through a main oil feed to a main bearing gallery, a cam gallery and a hydraulically actuated device such as a cam phaser or switching valve lifters. A pressure regulator connected between the main oil feed and the galleries selectively restricts oil flow to the galleries to raise oil pressure supplied to the hydraulically actuated device.
