5 Causes of Engine Oil Leaks and What to Do About Them

Monday, January 4, 2021



During the long winter months ahead, ensuring safety when you are on the road is crucial. One of the most common causes of damage to a car is an engine oil leak. If your car is leaking oil, the engine can rapidly deteriorate and stop working altogether. Engine oil leaks can even result in you losing control of your vehicle while on the road, which could lead to a crash.

That is why understanding the main car leaking oil causes and knowing exactly what to do about them is crucial. Read on to find out why your car might be leaking oil, and what you can do about it right now.

1. A Worn-Out Oil Filter

One of the most common causes of an oil leak under a car is a broken or degraded oil filter. A car oil filter is responsible for filtering contaminants out of the oil before they can cause any damage to your engine. Most work as planned, but after a few thousand miles on the road, they will start to degrade from overuse.

When the filter stops working, the oil will start to leak. In addition, pressure from inside the engine might cause the oil filter to become loose or otherwise displaced. Either way, correcting or replacing an oil filter is a straightforward task that can be done at home.

2. A Loose or Broken Filler Cap

Another very common cause of car engine oil leaks is when the filler cap for the oil tank becomes loose or breaks. It is usually easy to tell when this has happened, as telltale oil puddles will quickly form underneath your car or pool around the engine itself.

When it comes to engine oil leak repair, fixing this can take just a few seconds. First, readjust the filler cap to make sure it is not loose. If it will not stay-in-place, then you can simply buy a new filler cap and attach this yourself.

3. A Broken Gasket

The gaskets are an essential component of any car engine. They are responsible for the transfer of fluids such as oil, coolant, and gas throughout the car. However, gaskets will typically degrade over time, which will cause the seals that they create to weaken.

This usually happens after a long period of time, usually after 100,000 miles. If this is the cause of your oil leak, you will need to call a professional how will know exactly how to fix an oil leak in a car of this nature.

4. Too Much Oil

Often, what you think is an oil leak might just be the result of a simple error, and is no need to worry. If you are noticing oil puddles under your car but the dashboard engine oil light is not flashing, then you might have simply poured too much oil into the engine, causing an overflow.

It is also possible that you simply spilled some oil when filling it up. If this is the case, simply use a rag to clear up spilled oil on the engine. Also, use a dipstick tube to extract excess oil and the problem should be solved.
