Oil pump failure: The oil pump is responsible for circulating oil throughout the engine. If the oil pump fails, it will not be able to provide enough oil pressure to the engine.
Oil leak: An oil leak can cause the engine to lose oil, which can lead to a drop in oil pressure.
Low oil level: If the oil level is low, the engine will not have enough oil to circulate and provide adequate oil pressure.
Worn piston rings: Worn piston rings can allow oil to leak into the combustion chamber, reducing the amount of oil available to circulate through the engine. This can lead to a drop in oil pressure.
Oil cooler leaks: Oil cooler leaks can cause the engine to lose oil, leading to a drop in oil pressure.
