The oil pump cover is another key component of the oiling system. The
pressure relief valve, oil filter by-pass and oil filter inlet and outlet passages are all incorporated in this small but important piece. Replace when excessively worn, when the bypass is damaged or when the housing itself is physically damaged. Please note that over the years the clock position has changed slightly, but are fully compatible with all earlier designs.
Note: May not fit Jeeps with Buick engines (may hit radiator, etc)
