Insufficient fluid will be pushed in the pressurized channels when the engine is worn.
What happens when an engine wears out?
Engine has worn out. Since the oil pressure is made as the pump pushes oil through the oil passages and through the small spaces between the wear surfaces in the engine, when the engine becomes worn out, these spaces tend to become larger. The bearing clearance will be increased.
What is a worn out oil pump?
The oil pump is the one that makes sure that the engine oil is pumped into the engine’s oil passages to ensure that the engine is always lubricated.
