Oil Pump

The Oil Pump (in an internal combustion engine) circulates the engine oil through pressure into bearings, pistons and the Camshaft. It also assists in engine cooling.


Oil Filter:
The Oil Filter comes after the oil sump. So when the oil leaves the sump, it goes into the oil filter to get filtered before it gets fed to parts in the engine.


How it works:
The oil first comes in through the oil filter to make sure it's clean, after that it goes through to the sump (where the oil is stored). From there, it now goes into the oil pump. The oil pump then pushes oil into the pressure filter which then sends it the crankshaft, pistons etc.
