Causes And Preventions Of Engine Oil Leaks In Cars

Your car's engine oil is crucial to its lifespan, so an oil leak in your car is among the last things you want to happen. Oil leaks in your car might result in low oil pressure in addition to putting unneeded strain on your engine. There are various things to think about when a car leaks oil. Do not delay in fixing the problem if you observe typical indicators of an oil leak, such as dark puddles under your car or an illuminated oil light on the dashboard. You will get to know all the probable causes of engine oil leaks here. Our aim is to address all your top queries related to engine oil leaks in this article. We go over the most frequent causes of oil leaks in your car that should not be ignored. This post will explain the most common causes of engine oil leaks and how to fix them.

1. Rusty or Damaged Oil Pan

The oil pan can rust through since it is generally made of metal. It can potentially suffer damage from collisions with roadside objects and stones. There may be surface holes where oil can leak if the oil pan is broken or damaged. The seal around the drain plug can also get broken by the damaged oil pan.

2. Worn-out Gasket

Gaskets serve as seals between various auto parts, so it's not surprising that they provide a wealth of potential engine oil leak spots. There are numerous gaskets in your engine, and many of them might eventually wear out and cause an oil leak. Valve cover gasket, Cylinder head gasket, Timing cover gasket and oil pan gasket may be to blame if you believe your car is dripping oil, either internally or externally:

It might be challenging to locate a damaged or worn gasket without the necessary skills and knowledge. Make sure to have a Tyres Plus expert examine the vehicle to determine the problem.

3. Worn-out Seals

Your car has several seals in addition to gaskets that keep the oil inside the engine where it belongs. Crankshaft or camshaft seals may be to blame for any oil leaks you may have seen. 

At both ends of the crankshaft are crankshaft seals. These seals may cause leaks if they become broken, dry out, or break. A major leak can result in oil dripping onto the front or back of your engine, whereas a tiny leak often leaves oil at the bottom of your engine.

4. Stuffy Crankcase Ventilation

A mesh filter is frequently used in the crankcase ventilation system. This filter is more likely to become clogged as it ages with time. A Hoover leak that results from a blockage might cause a lot of performance problems. Additionally, the PCV valve is present, which is susceptible to clogging with time.

As a result, there will be an increase in crankcase pressure, which will lead to oil leaks in various locations. By taking off the oil cover, you may check the pressure within the engine while it's running.

5. Loose Drain Plug

The drain plug is always removed as part of the procedure to remove the old oil from a car's engine. This component can become loose because it is handled so frequently. The gasket or seal is a common feature of drain plugs that eventually wear out. Luckily, it's really simple to fix. You only need to tighten the plug if it was not fully tightened after the last oil change. If this doesn't solve the problem you'll just need to replace it.

6. Leaked Oil Filter

The leaking of oil filters in automobiles is one of the most frequent and obvious reasons for oil leakage.  Every time the oil is changed, it is advised to replace the oil filter as well. If you change your oil yourself, you risk forgetting this important step or installing the new filter incorrectly. Start by checking the oil filter seal if you're unsure where an oil leak is coming from. Check the oil filter for tightness and make sure the gasket or O-ring is not sticking out in an odd area.

7. Malfunctioning of Oil Pressure Sensor

If the oil pressure sensor is damaged or not working properly, the low oil light might illuminate. Additionally, the area surrounding the damaged sensor may begin to leak oil. The oil pressure sensor is essential to maintaining the engine's correct operation. At this time, continuing to drive could harm the engine.

How To Prevent Oil Leaks In Cars??

Early detection of oil leaks depends on routine maintenance and the corresponding inspections. Maintain regular oil changes, remember to change the filter, and drive carefully when off-roading over large boulders or other debris.  

In some situations, certain engine oils are specifically made to assist rejuvenate some types of gaskets and seals, which might be useful if a gasket or seal has recently started leaking from an older, high-mileage engine.  If this applies to you, ask your Tyres Plus salesperson for additional details.


It is intended for engine oil to never leave the motor. The automotive parts of a car are under a lot of strain because this isn't a perfect world. Valuable parts, both tiny and large, can begin to deteriorate over time due to high heat and heavy mileage. As these components break, an oil leak occurs. There are minor and significant oil leaks. Others are invisible, such as when the head gasket fails and an internal leak develops.

Whatever kind of oil leak you have, it's best to fix the issue right away. Running the engine without the appropriate amount of oil only causes severe damage. If you don't stay on top of things, something that might only cost you a small amount of money to fix today could quickly cost you an engine replacement.
