For an engine to operate smoothly, it relies on lubricants that flow through an oil pump. This pump’s essential role is to circulate engine oil throughout the engine, ensuring that moving components are properly lubricated. By doing so, it mitigates heat and prevents corrosion.

Where is the Oil Pump Located ?

The oil pump is usually situated behind the timing chain cover, positioned toward the lower section of the engine or beneath the oil pan.

Can You Drive the Car With Bad Oil Pump ?

It’s highly advisable not to drive the vehicle if you’ve identified a faulty oil pump. Operating the car with a bad oil pump can result in catastrophic engine damage.

Symptoms of Faulty Oil Pump:

Here are the symptoms of a Bad Oil Pump in a car:

1. Low Oil Pressure Warning Light:

The low oil pressure warning light on the dashboard acts as a crucial indicator, signaling potential issues within the oil lubrication system.

However, it’s essential to note that this warning light might illuminate due to factors beyond just a failing oil pump, such as a clogged oil filter, faulty pressure sensors, or insufficient oil levels.

Inspect for signs of a faulty oil pressure sensor to understand the underlying cause triggering the warning light.

2. Over Heating:

Increased engine temperature due to inadequate lubrication from the failing oil pump. Engine components may overheat, leading to the check engine light alerting about elevated temperatures on the dashboard gauge.

3. Noise From The Valve Train:

Unusual noise from the valve train system, caused by insufficient lubrication due to low oil pressure from a bad oil pump. This can result in rough operation, strange sounds, and potential failure of engine components.

4. No Start Condition:

No start condition in some newer models that prevent engine ignition if low oil pressure is detected. This is a safety feature to avoid further engine damage. Checking and maintaining proper engine oil levels can prevent symptoms similar to those of a bad oil pump.

5. Engine Noise:

Engine noise resulting from inadequate lubrication causing metal-on-metal contact between moving parts.

What Causes Oil Pump Failure?

The primary cause of a bad oil pump can be attributed to various factors:

1. Clogged Oil Pickup Screen:

Contaminants like sludge, metallic particles, dirt, or debris present in the oil can clog the oil pickup screen. This obstruction restricts the flow of engine oil to the pump, leading to insufficient lubrication. Increased friction in the oil pump due to the lack of proper lubrication can cause overheating and premature pump failure.

Regularly inspecting and cleaning or replacing the oil pickup screen during oil changes helps prevent damage to the engine.

2. Leakage:

Another common reason for oil pump failure could be the development of leaks. This could be caused by issues such as a faulty oil pump gasket, a bad oil pump seal, or damaged oil pump O-rings. If there’s a leak, it can lead to a decrease in oil level, resulting in the deterioration of the oil pump’s functionality and ultimately causing it to fail.

Regularly check the oil level using the dipstick and add more oil if needed.

3. Clogged Oil Filter:

A clogged oil filter can block oil flow, leading to increased strain on the oil pump and potential pump failure.

Regularly changing the oil filter during scheduled oil changes can prevent blockages and ensure proper oil flow, reducing strain on the oil pump and helping prevent potential pump failure.

3. Overused Oil :

Frequent oil changes are crucial to prevent the accumulation of sludge at the bottom of the oil pan. It’s important to adhere to the scheduled oil change intervals recommended for your vehicle.
