Identify Where Your Car is Leaking Oil
Identifying the source of your car’s oil leaks is essential for the necessary repairs. And luckily, half of the time you can DIY this at home.
Start by parking your car on a clean and dry surface and look underneath the vehicle for visible oil stains.
Majorly, you can check the areas around the engine, transmission, and differential. If there are a lot of oil leaks, it may drip or run down the specific components of your vehicle.
Note: Always use a flashlight for a thorough inspection of oil under the car when parked.
However, if you’re still unsure about the source of an oil leak, it’s recommended to consult a professional mechanic with the required tools and expertise to diagnose the problem and recommend the appropriate repairs.
Here are a few reasons why the oil leaks when the car is parked.
- Oil spills during the filter replacement usually cause the drips and should stop as the leftover oil dissipates
- Look for a faulty seal or gasket in the engine and monitor your oil levels
Common Causes of Leak Oil
Oil leaks are one of the most common automotive problems among many car owners. Many factors contribute to oil leaks when parked.
Faulty Gaskets or Seals
Faulty gaskets or worn and damaged gaskets allow the oil in your engine to seep out.
- If you have a faulty valve cover gasket, the oil leaks onto the engine’s exterior.
- If you have a damaged crankshaft seal, the oil leaks from the front of the engine.
- A compromised camshaft seal allows your engine oil to leak from the back of the engine and a faulty rear main seal leaks the oil at the rear of the engine.
Therefore, inspect the source of the oil leaks properly and consult your mechanic when needed.
Damaged Oil Filler Cap
If the oil filler cap is damaged or improperly fitted, it can contribute to oil leaks in your vehicle.
A loosely fitted cap creates a gap to allow oil to escape. This is especially possible when the engine is running and the oil pressure is high. Also, the damaged threads in your oil filler cap prevent the cap from sealing properly, ultimately leading to an oil leak when parked.
It’s always recommended to inspect the cap and check for any visible damage to the threads or consult a mechanic to inspect the filler neck and cap to determine the exact cause of the issue.
Damaged Oil Pan or Oil Filter
If your oil pan is cracked or punctured due to corrosion, impacts, or excessive heat, chances are your oil leaks are coming from your oil pan or oil filter.
Inspect your oil filter for damages and cracks and consult your mechanic for replacement as soon as possible to avoid serious engine issues.
Camshaft and Crankshaft Seals
Camshaft and crankshaft seals are important components to prevent oil leaks in your vehicle. Therefore, if they become damaged or worn out, the oil may leak.
Camshaft seals are located at the ends of the camshaft to prevent oil from escaping between the camshaft and the engine block. Over time, they become cracked due to heat, vibration, and exposure to engine fluids, allowing your oil to leak.
Similarly, crankshaft seals are located at the front and rear of the engine to prevent oil leaks. However, when they become damaged, they fail to prevent oil leaks, leading to more serious engine problems, if left unaddressed.
Bad Rear Main Seal
Over time, the rear main seal becomes damaged or worn out due to many reasons, such as heat, vibration, and constant oil pressure. As a result, gaps or cracks develop, allowing your oil to leak.
A bad rear main seal leaks the oil from the rear of the engine, leading to a loss of oil pressure, which can further damage the engine if not diagnosed and repaired.
How To Fix an Oil Leak
Fixing an oil leak is not something you should DIY at home. It requires the expertise and knowledge of a professional mechanic.
However, you can easily fix some minor leaks with DIY methods, such as tightening a loose oil drain plug or replacing a worn gasket. Mostly, there are more serious issues, resulting in cars leaks oil only when running or parked that require professional assistance.
Here’s what a professional mechanic would usually suggest to fix your car oil leaks.
Replacing the Gaskets or Seal
Your professional mechanic may ask you to replace the damaged gasket or seal and install a new one compatible with your vehicle
Replacing/Repairing Damaged Components
If the oil leaks are due to a damaged component. For example, an oil pan or crankshaft, replacing or repairing the damaged components is the only way to fix the issue.
Additionally, if the oil leaks are severe and other repairs are impossible, your technician or mechanic may suggest replacing the complete engine.

The Cost of Ignoring Oil Leaks
The cost of ignoring oil leaks is often irreparable. That’s because if your engine is leaking oil, you’re going to face oil-level issues, which may lead to several serious problems.
Without lubrication, the components of your engine can wear down and fail, resulting in complete engine damage, which may cost you expensive repairs or even engine replacement.
Additionally, reduced oil levels may also affect your engine performance adversely, leading to decreased power and fuel economy. Also, engine damage may lead to increased emissions, harmful to the environment, contributing to air pollution.
Therefore, it’s crucial to address the oil leaks promptly and consult a professional mechanic to avoid these costly and potentially dangerous consequences.
Tips to Minimize Oil Leaks in Your Vehicle
Oil leaks are frustrating and expensive problems that may add to your future expenses. Here are a few tips to help minimize oil leaks in your vehicle.
Do Not Overfill Your Oil
Maintaining proper oil levels is crucial to prevent oil leaks. That’s because overfilling the tank may put excessive pressure on the seals and gaskets, allowing them to fail abruptly.
Therefore, always check the oil levels using a dipstick and avoid overfilling your tank.
Use The Right Type Of Oil
Your vehicle comes with a user manual for a reason. Using the incorrect or inferior quality oil type can lead to premature wear and tear on engine components, resulting in oil leaks.
Always refer to your user manual for the right type of oil and viscosity.
Conduct Routine Inspections
Regular maintenance and routine inspections are important for diagnosing oil leaks promptly.
Always check for the signs of potential oil stains on the parking ground, under the vehicle, or on the engine.
In case of any leaks, inspect your vehicle properly and consult a professional mechanic to diagnose the issue.
