What is this and what does it take to repair?

Oil leak at an unknown unit ( pressure relief valve) that opens into the oil pan located the bottom left side of the block just forward of the oil filter. Is connected to another unknown unit above by a tube. The lower unit appears to consist of a lower (part of the block?) And upper section. The leak is between these two sections. Is there gasket to be replaced? How?

Lubrication is provided by a gear driven eccentric type pump. Oil from pump goes through a full-flow oil filter to all moving engine components. Oil is then passed through an oil cooler and returned to oil pan.
