If you check MOT history of your vehicle, you'll find that an excessive oil oil leak was the cause of failure or that a tiny oil leak was an 'advisory' that needed to be corrected. An oil leak in your car's engine should not be ignored since it might be disastrous.

You should not ignore an oil leak in your car's engine since it might be dangerous. Aside from engine failure,What 5 causes an oil leak to happen? Articles oil leaks can cause a fire in your engine bay or danger for other drivers on the road if there is enough oil spilled.

Fixing oil leaks should be a top priority and taking care of your vehicle is necessary. It doesn't always take a qualified mechanic to find out the best answer, there are some things you can do on your own to stop engine oil leaks. Before you can do that, you need to figure out what's causing the leak and where it's coming from.

5 causes of an oil leak

The following are 5 causes of an oil leak:

1. Time

Due to multiple heat cycles and oxidation, your oil might lose viscosity while you drive your car. Your gaskets, hoses, and other rubber components that keep oil and other fluids in their proper reservoirs and chambers can also deteriorate over time.

2. Incorrect installation

There are times when one of your car's gaskets or parts is placed incorrectly. That suggests either the oil pan or valve cover is overtightened, or the tightness isn't spread evenly. It might also be the oil filter's faulty installation, which, if loose, could cause a leak in your automobile. You might potentially have a poor seal around your oil pump or an incorrectly fitting hose clamp on an oil line. Check MOT status of your vehicle and have this issue repaired by your car mechanic.

3. Accidents or physical damage

Road debris can damage your car's oil pans and gaskets. As a result of the rough roads, a hole might form, causing an oil pan leak. Your oil pans and gaskets may be damaged by stone chips, boulders, and other road mishaps. If your MOT status is still valid, have this problem looked at and fixed by your car mechanic before your next MOT test.

4. Heat

While engines and oil have an ideal working temperature, excessive heat may cause your engine oil to thin out prematurely and seep out of your oil seals. Too much heat, on the other hand, may prematurely age your car's gaskets, oil seals, and hoses.

5. Too much engine oil

There's such a thing as too much of a good thing can be bad, and in the case of oil, too much can lead to an overflow. There may be too much oil in your car's engine, and it's leaking out of the top reaches of the engine, such as valves and various breather hoses. Check MOT expiry date for your vehicle and get your mechanic to rectify the correct amount of engine oil in your car.

Common oil leak areas

After going through the many causes of oil leaks, you may already be aware of the usual locations or regions where oil leaks occur. The damaged or worn-out gaskets, as well as the rings or valve seals, are as follows:

• Gaskets and seals

• Oil pan

• Oil lines

• Oil filter

• Oil drain bolt

How do you find an oil leak?

After you've gone over the essentials, you'll need to figure out if your car is actually leaking oil before you can figure out how to fix it. It's also worth noting that the oil on your car is most likely the product of road filth and other cars' fluid, not necessarily yours.

Step 1 - Check the leak to see if it's indeed an oil leak - You must first view your car for yourself before concluding that it is oozing with oil. Examine the drips under your car and try to capture some of the fluid by laying down newspaper or a white plastic plate. Try blotting oil on a surface with paper towels to examine the colour and properties of the seeping fluid. A sluggish leak will seep out, but a rapid leak will drip.

Step 2 - Check your fluid levels - It's critical to check your fluid levels on a frequent basis. The dipstick may be used to check the oil level. If your oil level is low, it's likely that you haven't changed it in a while or that there is a leak. If your oil level is low, it's time for an oil change; however, if you've just had an oil change and are still running low, there might be a leak.

Step 3 - Find the source of the leak - You may hire a mechanic to handle this, or if you're ready to do some dirty work, you can play detective and find the source of the leak yourself.

Step 4 - Consult an expert - If you don't want to perform the dirty work yourself, you may hire a car mechanic or technician to do it for you.
