Oil leaks in cars can be a frustrating and sometimes alarming problem. Identifying the root cause is essential to prevent further damage to your vehicle and ensure it runs smoothly.
Worn Out Gaskets and Seals
Over time, the gaskets and seals in your engine can wear out, causing lubricant to seep through the cracks. These components are responsible for keeping lubricant inside the engine, and when they fail, lubricant can leak out. The most common culprits include:
- Valve cover gaskets
- Oil pan gaskets
- Rear main seal
If you notice petroleum pooling under your car, it’s important to have these parts inspected and replaced if necessary.
Loose or Damaged Oil Filter
The oil filter plays a crucial role in keeping your engine’s lubricant clean. However, if the filter is loose or damaged, fluid can leak from it. After an fluid change, the filter might not be secured tightly, or it could have been damaged during installation.
To prevent lubricant leaks, make sure the lubricant filter is properly installed during fluid changes and consider replacing it if it’s old or worn.
Worn-Out Drain Plug or Washer
The drain plug is located at the bottom of the lubricant pan and is used to drain old petroleum during a lubricant change. If the plug or its washer becomes damaged or worn out, it can result in an petroleum leak. The washer is particularly susceptible to wear and tear over time.
During your next lubricant change, have the drain plug and washer checked and replaced if necessary to stop the petroleum from leaking.
Cracks in the Oil Pan
The petroleum pan holds the petroleum that lubricates your engine. Over time, the petroleum pan can become damaged due to impacts from debris or rough roads. Cracks or punctures in the fluid pan will allow fluid to leak out.
In the event of a cracked petroleum pan, you may need to replace it to stop the leak. In some cases, a temporary fix like a sealant may help until a more permanent repair can be done.
Overfilled or Incorrect Oil Levels
Putting too much petroleum in your car can cause pressure to build up in the engine, which can force petroleum out through seals and gaskets. Similarly, using the wrong type of oil can lead to leaks.
Always check your vehicle’s owner manual for the recommended fluid type and capacity, and ensure that your oil levels are within the correct range after an oil change.
