There are many reasons for low oil pressure. Insufficient engine oil pressure can cause engine failure. It is therefore essential to be vigilant. Let’s look at the causes of low oil pressure and what can be done about it.
Insufficient engine oil pressure: how to detect it?
An oil can represent the specific red light on the dashboard indicating a drop in engine oil pressure. The driver is alerted when this light comes on.
Good to know: as soon as the oil pressure warning light comes on, it is best to stop the engine because insufficient oil pressure no longer allows for proper lubrication of this essential organ. This can lead to a breakdown.
Causes of low engine oil pressure
Insufficient engine oil pressure can be the result of a malfunctioning part.
Oil pressure sensor failure
A properly functioning oil pressure sensor ensures lubrication of the engine and all internal components. In addition, the sensor helps cool parts that are subject to thermal shocks, such as connecting rods, cylinders, bearings and pistons.
A malfunctioning sensor can cause oil leakage, which leads to an increase in oil temperature and therefore wears on specific engine components. A malfunctioning sensor most often results in a leak in the compression chamber, damaging all sensor components.
Oil pump wear
The oil pump’s job is to circulate engine oil to lubricate the engine components. This prevents premature wear of the parts and reduces their friction. The pump draws oil from the bottom of the crankcase and then pumps it into the engine block and cylinder head.
A drop in the engine oil level can therefore lead to an oil pump failure.
Good to know: a malfunction of these engine parts can affect the safety of passengers. It is therefore essential to contact a mechanic as soon as possible if you notice low oil pressure.
How do I test the engine oil pressure?
A pressure tester is used to test the engine oil pressure. It comes in the form of a kit that includes:
– an oil pressure indicator graduated from 0 to 10 bars called a manometer;
– a flexible hose with a connector;
You must connect the pressure gauge to the pressure switch on the oil filter support to determine the oil pressure. Depending on the engine speed, the pressure value is about 3 bars when the engine runs at 1,000 rpm, and 4 bars when it runs at 4,000 rpm.
Good to know: you can use the pressure meter on all gasoline or diesel engines.
What should I do if I have insufficient engine oil pressure?
Insufficient engine oil pressure requires action. This often involves replacing the oil pump or the oil pressure sensor.
The defective parts must be removed and replaced. Not everyone can do this. It is therefore recommended that you visit a garage as soon as possible.
Good to know: If you want to do the repair work yourself, be sure to look for the right part for your vehicle type and model.
Price of replacement parts
The price of parts varies depending on the type and model of the vehicle with low engine oil pressure.
The price of an oil pressure sensor is generally between $10 and $30. As for the oil pump, it costs between $100 and $300.
An oil pressure gauge is generally sold between $30 and $50.
Good to know: the cost of labour is quite important for this type of intervention. It will help if you plan on a budget of $200 to $300, depending on the work to be done and the time spent. This fee is charged in addition to the cost of replacement parts.
