The oil sump contains the engine oil required for lubrication.
The oil is extracted from it by an oil pump and conveyed into the engine block’s oil ducts via the oil filter. The oil then flows back into the oil sump from the lubrication points.
The sump is generally bolted on at the lowest point of the engine, below the crank mechanism on the crankcase.
It features an oil drain plug, the opening of which in the sump allows the oil to drain out when changed.
However, the oil sump is not merely a storage container. It performs one additional function, cooling the heated oil which flows back into the sump. The car sump is generally made of deep-drawn sheet metal.
The sump’s cooling effect can be improved through the addition of fins on the housing. Oil pan in passenger cars must be made of more sturdy aluminum or steel, partly due to their strength.
Fascinating that this little tray can be so important to a running car.
The oil pan is normally very robust and durable. Nonetheless, it can be damaged by hitting the ground while driving or due to age-related defects in the seals.
If it is damaged, it is important to seek out a workshop immediately to prevent oil from leaking.
Continuous oil loss will cause the engine to no longer to get sufficient lubrication.
This can result in the risk of engine damage, which will incur significant repair costs. When topping up oil, it is absolutely imperative not to fill the oil tray above its maximum limit.
There is a danger of the crankshaft being dipped in the oil while the engine is running and consequently causing small air bubbles to spread through the oil. Such air bubbles can cause lubrication to be less effective.
