An oil pan is a dark-colored part that seals the bottom part of the crankcase and contains the engine oil before and after it has circulated through the engine. An oil pan is essentially responsible for lubricating various parts of the engine.
Lubricating the engine parts reduces friction and increases their efficiency and longevity. The oil pan also prevents the engine oil from leaking (to other parts), keeping it within the lubricating system. A gasket covers the oil pan to keep the oil contained. When the engine is functional, the oil pump sucks oil from the pan and circulates it through various parts of the engine. Once all components are lubricated, the used oil returns to the pan. The size of the oil pan determines the amount of oil an engine can hold.
An engine will only hold the amount of oil the pan can store without dipping the crankshaft. A dipped crankshaft will ventilate the oil, making it difficult to circulate into the engine.
