Common Reasons for Oil Leaks After an Oil Change

Incorrectly Installed Oil Filter

The oil filter is an essential component of your car’s engine. If it’s not installed correctly during an oil change, it can cause oil to leak. This is often due to the oil filter being too loose or too tight.

Damaged Oil Pan

The oil pan is located at the bottom of the engine and holds the oil. If it’s damaged, it can cause an oil leak. This damage can occur due to rough driving conditions or if it’s accidentally hit during an oil change.

Poor Quality Oil Filter or Oil

Using a poor-quality oil filter or oil can also lead to oil leaks. These products may not be able to withstand the pressure and temperature of the engine, leading to failures and leaks.

Overfilling the Engine Oil

If too much oil is added during an oil change, it can cause an oil leak. Overfilling the engine oil can cause excess pressure in the system, leading to leaks.

Signs of an Oil Leak After an Oil Change

Smoke from the Engine 

If oil is leaking onto hot parts of the engine, it can cause smoke. If you notice smoke coming from your engine after an oil change, it could be due to an oil leak.

Burning Oil Smell

A burning oil smell is another sign of an oil leak. This smell is often noticeable when the car is running and is a sign that oil is leaking onto hot parts of the engine.

Decrease in Oil Levels 

If you notice that your car’s oil level is decreasing faster than usual, it could be a sign of an oil leak. It’s important to check your oil levels regularly to ensure that your engine is properly lubricated.

First, check the oil level in your car. If it’s too high, it could be causing an oil leak. In this case, you’ll need to drain some of the oil to bring it to the correct level.

Inspect the Oil Filter

Next, inspect the oil filter. If it’s too loose or too tight, it could be causing an oil leak. Adjust the oil filter as necessary, or consider replacing it if it’s damaged or of poor quality.

Look for Damage to the Oil Pan

Inspect the oil pan for any signs of damage. If you notice any cracks or holes, you’ll need to have the oil pan repaired or replaced to prevent further leaks.

Consult a Professional

If you’re unable to identify or fix the source of the leak yourself, it’s best to consult a professional. You can consult a mechanic online to help you figure out what the cause of the issue is and walk you through how to fix it step by step. Or speak to a local mechanic, as they can perform a thorough inspection and repair any issues that are causing the oil leak.
