What are the causes of oil leaks in cars?

Oil leaks in automobiles can occur for a variety of reasons. You may have a faulty seal or a damaged gasket. Or perhaps your vehicle has been damaged. The following factors may contribute to an oil leak, depending on the seriousness of the spill.

  • Bad oil filter
  • Worn-out valve cover gasket
  • Loose drain plug
  • Damage oil pan

Bad oil filter

An oil filter does exactly what it says on the tin: it filters impurities out of the engine oil. This keeps the oil clean and prevents clogs and wear in the engine. At the same time, if the oil is not changed, an oil filter can become blocked. The oil filter may rupture as the pressure develops, causing oil leaks.

A carelessly installed oil filter is another cause of oil leaks. Because the oil in an engine moves at a specific pressure, even a little gap might produce a leak. Keep an eye out for this following an oil change, as the mechanic may not have installed the filter correctly.  If the wrong oil filter is used, oil leaks from the oil filter can occur. The oil filter may not seal correctly in this instance, resulting in low oil pressure and leaks.

Worn-out valve cover gasket

A valve cover gasket is a rubber seal that connects the valve cover to the cylinder head’s upper part. Due to heat and pressure, a gasket hardens over time and develops cracks. If the oil pressure rises, this creates unexpected and sudden leaks. Alternatively, drive slowly as you do every day in your automobile.

Your car may have one or many gaskets, depending on the type of engine. You’ll have two valve covers if you drive a V-6 or V-8. You only have one cylinder in a straight-4 or 6-cylinder engine. A valve cover gasket typically lasts 20,000 to 50,000 miles. The heat created by oil leaks might cause smoke or fire if they are not replaced. Alternatively, due to wear and tear, the constantly diminishing oil can cause your engine to fail.

Loose drain plug

Drain plugs are plugs that allow engine oil to drain. It is attached to the oil pan and is located under the car. It’s difficult to miss if you’re in the car. A loose drain plug can cause oil leaks because all of the engine oil collects in the oil pan. Oil streaks would be present around and beneath a leaky drain stopper. If you’ve recently had your oil changed, you have even more reason to check your drain plug.

Damage oil pan

An oil pan is a storage container for oil that collects all of the oil while it is not in use. When you’re not driving or your engine is turned off, that is. It’s also where the air traveling over the surface of the oil pan cools the oil.

Oil leaks from oil pans are uncommon because they are firmly fitting. However, any damage or a loose-fitting pan can result in an oil leak. An oil leak can also occur if the oil pan gasket, like the worn-out valve cover gasket, wears out. These are the most common causes of oil leaks. But how can we tell if there’s an oil leak? What are the signs and symptoms to watch for?

How to know if there is an oil leak in my car?

Oil leaks in vehicles appear in a number of ways. Symptoms can be found by looking around, and they include:

  • Oil spills
  • Check engine oil light is on
  • Smoke from the engine
  • Engine Overheating
  • Burning oil smell

Oil spills

The most visible symptom of an oil leak is an oil spill. If your vehicle is leaking, it will cause a spill or splatter underneath it. You might observe a few droplets or a small puddle depending on the extent of the leak. Whatever the case may be, an oil spill just beneath your vehicle indicates that your engine oil is leaking. And you should have it checked out right now.

Check engine oil light is on

Another symptom of an oil leak is if your dashboard’s check engine oil light is illuminated. It is the ideal indication for oil leaks because it only lights up when the oil level is too low. If the light comes on while you’re driving, you should pull over to the side of the road and inspect your car. Look for oil spills if it lights up when you start your automobile. Check the oil level in any situation where the check engine oil light turns on.

Smoke from the engine

Smoke coming from the engine might be produced by a faulty cooling system, wiring issues, or fluid leaks, among other reasons. When transmission fluid, brake fluid, or engine oil seeps onto a hot engine component, it can cause smoke.

If you notice your engine is smoking, pull over to a safe location. Turn off the engine and wait for it to cool down. Then, pop the hood to see what’s wrong. Also, only use the fire extinguisher if flames are visible. Otherwise, the fire extinguisher will cause more harm than good.

Engine Overheating

Engine oil serves as both a lubricant and a filter, as well as a coolant. It circulates through the various components of the engine, cooling it down. In the event of an oil leak, the oil level drops as the cooling effect reduces. The engine may overheat as a result of this.

Burning oil smell

Oil leaking from the valve cover has the potential to contaminate other engine components. Furthermore, because they are piping hot while driving, they emit a burning oil odor. It’s definitely burning oil under your hood if you smell something unpleasant.

How can I find an oil leak from my car?

While there are a variety of causes for oil leaks, determining the source is very simple. You may quickly find the source of the oil leak by inspecting a few spots. Begin by:

Examining the signs and symptoms:

Begin by searching for any signs or symptoms. Find out where the oil spill is coming from and how severe it is. Is there smoke or a burning odor if there aren’t any oil spills? Both of these things can happen as a result of an oil leak in the engine bay. Keep in mind that severe oil leaks or a low engine oil level might cause engine overheating.

Take a look beneath your vehicle:

Check beneath the vehicle if there is an oil spill. Check for leaks in your oil pan or drain plug. Cleaning the oil and checking in again after some time is an easy way to validate this. If you see additional oil, it’s most likely due to a problem with your oil pan or drain stopper.

Examine under the hood:

Your engine is another area to look at. Look under the hood to see if there are any oil streaks. If you can’t find it, look around your valve cover or the oil filter. If there is oil directly beneath the filter, there is an issue.

Can I drive a car with an engine oil leak?

While a few drops of leaking engine oil may appear little, they could be a signal of something more serious. Check the engine oil level after observing spilled oil. Before starting the engine, apply oil if necessary. Drive to an auto repair shop if the level is acceptable. If there is a significant amount of oil spilled, you should have your automobile towed to a technician.

How can I fix an oil leak in my car?

It’s time to roll up your sleeves and learn how to remedy an oil leak after you’ve completed your inspection. You don’t need to read a whole book to figure out how to repair that leak. While some oil leaks require costly repairs, the majority of them may be repaired quite inexpensively in your garage or driveway.

Only a car jack, jack stands, torque wrench, and some special additives or replacement parts are required (something like a new oil pan). Here are the two most common methods for repairing an oil leak.

  • Using additives to stop the leak
  • Fixing the leakage with tools


Using additives to stop the leak

Using a stop leak additive or a high mileage oil blend is one of the simplest ways to remedy the leak yourself. Such chemicals can soften and condition your car’s rubber seals, thereby stopping and preventing further leaks.

It could take many hundred miles of driving to completely seal the leak. After that, you’ll discover how to cope with an oil pan leak and other types of oil leaks. Before employing a stop leak, you should first try to fix the leak by replacing components.

Fixing the leakage with tools

Don’t be concerned. It’s not as difficult as you would think to fix an oil pan leak or other problems with tools. Hand tools, a torque wrench, a car jack, and stands or ramps are all you’ll need.

First, jack up the automobile so you can get to the oil pan safely. Check the oil pan for any loose bolts now. These bolts might loosen over time, and loose bolts leak. Proceed to the timing belt cover and valve covers after tightening all of the bolts on the oil pan. Keep in mind that certain car models require tightening nuts in a specific pattern to a specific tolerance level. For further information, consult a service manual or repair guide.

Test running if the leaks stop

It’s time to put everything to the test once you think you’ve solved the problem. Fill up your oil tank with around a quart of oil. After that, you’ll want to start the car with the hood up. While the automobile is running, inspect the top of the engine. You may discover that oil is seeping from the gasket or the oil cap, and the engine may begin to smoke as a result of the oil burning. It’s critical to understand what causes oil leaks in all areas of your car.

After a few minutes of driving, park the automobile about 5 feet away from where it was previously parked. Examine the driveway for any oil leaks that have developed. If you still see an oil puddle, double-check that your bolts are properly tightened.

How often should I change my car oil?

All of this raises the question of how often you should replace your car’s oil. There’s no way to tell if your oil needs to be changed by looking at it because pure black oil becomes brown and “dirty” almost shortly after it’s placed into your automobile.

To avoid a big oil leak, the simple approach is to change your oil as often as the manufacturer suggests. The manufacturer’s advice is designed to keep your automobile running for as long as possible; you can find out what it is by consulting your owner’s manual, checking the manufacturer’s website, or calling the service desk at your local dealership.

Fortunately, there is no risk in having your oil changed too regularly, although it can be expensive. There’s no need to change the oil more frequently than the manufacturer suggests.

How many miles should it be for the oil changing?

It’s worth noting that your manufacturer’s advice will include mileage, which is a more solid indicator than a timetable. Some vehicle owners just get their oil changed every five to six months, but this does not account for seasons when the vehicles are driven more or less than usual.

In terms of particular mileage, each car is unique. Older automobiles could only get 3,500 miles out of a single oil change, whereas current cars can get 7,000 to 10,000 miles out of a single oil change. Again, the most important thing is to follow your manufacturer’s recommendations and get your oil changed as soon as possible, ideally before your light turns on or you see oil leaks in your driveway.


When my car is parked, why does it leak oil?

If you see a puddle of greasy-looking liquid on the ground after your car has been parked for a long, you may have an oil pan leak, which is caused by holes in the oil pan or gaskets. Take your car to a mechanic right away.

What is the cost of repairing an oil leak?

The cost will vary depending on whether the leak is severe or minor, as different treatments are available. It also relies on the vehicle’s make, model, and engine, as well as the leak’s location.

If my car leaks oil, do I need an oil change?

The leak will not be fixed by simply changing the oil. You must first determine the source of the leak, make the required repairs, and then either top up or replace the oil, depending on how much has been lost.

Is it safe to drive if I have an oil leak?

It’s usually best not to drive if your vehicle has an oil leak, although short distance drives (less than 10 miles) are less unsafe when it comes to dangerously low oil levels.

Is an oil spill a serious problem?

The severity of an oil leak in a vehicle is determined by various factors, including the leak’s location and size. Obviously, a big oil leak will cause your oil levels to drop faster, resulting in other, more serious issues. A leak from the front crank seal or timing cover can limit the life of the timing belt or engine drive belts, whereas a valve cover gasket leak will get oil on the hot exhaust manifold, potentially producing smoke or even fire.

How do I put an end to an oil leak?

Although there are various DIY leak-stopping devices on the market, sending your car to a shop is the best option because accurately identifying the underlying reason is critical.
