How To Check For Engine Oil Leak
Highlights
- An engine oil leak is a threat to the vehicle owner and fellow motorists.
- The ideal way to spot an oil leak is by inspecting the underbelly.
- It is better to change the oil and oil filter during regular servicing.
What Causes Oil Leakage and How Can You Prevent It?
Your car, just like other devices or instruments, can be vulnerable to malfunctions. Its components, in particular the engine, brake, battery, and steering. However, one of the most worrying things that can happen is when you see that your car's engine oil is leaking. And what makes this most distressing is when you fail to spot the area where the oil is leaking.
What causes engine oil leaks?
There could be possible signs of oil leakage, and if you see any of these, you must make an appointment with a mechanic before it's too late. Here are some of the reasons for oil leakage:
- Oil Filter
A loosely fitted, shabby or overused oil filter could be one of the primary causes of oil leakage. It must be changed every time you change the engine oil.
- Oil Filler Caps
If the oil filler cap is loosely fitted, the oil can also pour out because of movement during the drive.
- Oil Drain Plug
There is a drain plug located at the base of the oil pan under the car. If it is worn out, loosely fitted or misaligned, it can cause oil leakage.
- Valve gasket
It is a seal that joins two mechanical parts, such as an oil pan and an engine block. If a valve gasket is faulty, worn out, or badly installed, it can cause a leak.
- Damaged oil pan
Sometimes the underbelly of the car scrapes on bumps or speed breakers, causing damage to the oil pan and leading to oil leakage.
How to Detect Engine Oil Leaks
While it may appear to be a simple task to some, it can be a daunting one for others. Starting with the leaked patch on the surface can be the easiest way of investigating the leakage. Generally, the leakage flows downwards and can stream backwards during the drive because of wind.
The most precise way to figure out the exact location is to check the underbelly of the car from the rear. At the place, you would find deposits of dust and sludge all over it. There could be other places where fresh oil is coming out, and the ideal way to detect them is to clean those spots with a cloth. Apply some foot pressure to the area you think is leaking and start the engine to build up the pressure. Once enough pressure is built, remove the foot, and you will see fresh oil coming out of that area.
Takeaway
Unchecked leaks can cause the seals or rubber hoses to corrode prematurely and overheat the engine. Besides being a grave environmental hazard, an oil leak is a dangerous thing that can happen in the engine compartment, leading to catastrophic failure. So, oil leaks should be fixed right away to avert potential damage to your vehicle.
