Once an engine develops a noise like this, there is no easy fix. Typically, you'll need to dig deep into the engine to either fix the noise by replacing internal engine parts (camshaft or crankshaft) or replacing the complete engine. Once an engine runs low on oil to the point where the engine makes noise, it's usually too late; the damage is done. When you have a low level of oil in your engine, this will cause the components of the valvetrain to cause ticking sounds because the components are not being lubricated enough. The reason for low engine oil could be due to a leak somewhere. Perhaps you have damaged or worn out gaskets or seals. The most common cause of all of these knocking problems is loss of oil pressure from a clogged filter and oil pickup screen causing oil pump failure or just running the engine low on oil from oil loss through oil burning, oil leaks, and lack of maintenance oil and filter changes. If you continue to drive your vehicle even though it has a low level of oil, a knocking sound will be the final symptom. The reason is because there is less oil to lubricate the engine parts. This will cause your engine’s rods to loosen as more friction develops. These rods are responsible for securing the pistons of the vehicle. If you ignore all of the other symptoms of low oil in your car, then you could be headed for the final symptom of low oil which is a knocking sound. According to Auto Haus AZ, the friction that oil is supposed to prevent will eventually cause the rods inside your engine to come loose if the oil level has dropped significantly. An engine ticking noise might seem fairly normal, but it could be an early sign of low oil pressure. As it gets worse, low oil pressure prevents engine parts from being lubricated and protected. It doesn’t take long until it gets much, much worse. Low oil pressure can be caused by a failing oil pump but it’s much more likely it’s due to lack of maintenance.
The first time I ran across the Chevy engine oil pressure problem the customer complained about an oil gauge that read zero and a check engine light.
