What it does

The oil pump is the heart of the lubrication system: it pulls oil from the pan and forces it through the galleries to the crank and cam bearings, lifters and timing set. A worn pump loses pressure hot, which is how bearings and lifters die. A fresh pump restores full oil pressure at idle and under load.
