Reason Why Your Car Oil Filter is Leaking

Your car spilling oil can be a total nightmare! This can happen due to various reasons – the notorious gasket between the oil pan and the lid being the most common. But wait, there’s more! Check out these other potential culprits:

  • Double gasket
  • Oil filter gasket
  • Over or under-tightening
  • Filter housing (oil filter mounting adapter)
  • Damaged threads
  • Wrong filter
  • Damaged oil filter housing

Double gasket


A double gasket is often the culprit for oil filter leakage. When you install an oil filter, it should come with two gaskets: one to go between the mounting adapter and the engine block, and another to go between the adapter and the filter. If either of these components are missing or not properly aligned, then a double gasket can form, causing oil to leak out of the filter.

Oil filter gasket

The gasket between the oil filter and the mounting adapter is an important component that must be intact for a proper seal.

If it is damaged, curved or warped in any way, then this can lead to leakage around the filter. This type of gasket should be replaced with a new one as soon as possible to avoid further leaking.

Over or under-tightening

If the oil filter is tightened too much, it can cause the gaskets to be crushed and leak oil. On the other hand, if it is not tightened enough, then a weak seal could form, allowing oil to escape from the filter.

It’s important to take the time to properly tighten the filter, as it can make a big difference in preventing this kind of leak.

Filter housing (oil filter mounting adapter)

Your oil filter mounting adapter may also be causing your oil leak. If it is cracked or damaged in any way, then oil will be able to escape from the system.

If you notice any cracks or other signs of damage, it is best to replace the adapter as soon as possible.

Damaged threads

If there is a problem with the threads on either the filter or the mounting adapter, this can result in a leak. This is because oil will be able to escape through these cracks and gaps which should be sealed tightly.

To fix this problem, you can use a thread sealant to restore the threads and ensure that all of the oil is contained within the system.

Wrong filter

Using an incorrect filter for your vehicle can also lead to a leaky oil filter. This is because certain filters are made for specific vehicles and types of engines, and using the wrong one can cause an improper seal.

To avoid this issue, be sure to double check the filter size and type before installation to make sure that it is the correct one for your car.

Damaged oil filter housing

Finally, if your oil filter housing is damaged or cracked, then this can lead to leakage as well. This is because the oil will be able to escape through these cracks and gaps. If you notice any damage to the housing, it is best to replace it as soon as possible.

Knowing the causes of a leaking oil filter can help you take steps to prevent them in the future. Be sure to check all components of your oil filter system regularly and ensure that they are properly installed and functioning correctly.

Also, be sure to use the right filter for your car, as this can make a big difference in avoiding any leakage. With these tips in mind, you’ll be able to maintain a leak-free oil filter system and keep your car running smoothly.

Understand when it is time to replace your car oil filter

It is important to replace your car oil filter on a regular basis in order to prevent further issues with leaks. How often you should replace it depends on the make and model of your vehicle, as well as the type of oil being used.

Generally speaking, most cars require an oil change every 6 months or 5,000 miles (8,047 kilometers). At each oil change, you should also replace the filter. However, if you notice any signs of a leak or any other issue with your filter system, it is best to consult a professional mechanic who can inspect your vehicle and determine if a replacement is necessary.

Learn about the different types of car oil filters that are available on the market

When it comes to choosing an oil filter for your car, there are many different types to choose from. The most popular type is a paper element filter, which uses pleated layers of paper to act as a barrier between the engine and any dirt or debris that may be present in the oil.

Other types of filters include full-flow filters, bypass filters and spin-on filters. It’s important to research the different types of filters available and select one that meets your car’s specific needs.

How to effectively and safely change an oil filter without causing more damage

Now that you’ve chosen the right filter for your car, it’s time to change it. This is a relatively simple task, but there are certain safety measures and precautions that you should take in order to avoid further damage to your engine or filter system.

First off: make sure that you have all of the necessary tools and supplies on hand before you begin. This includes a drain pan, ratchet and socket set, oil filter wrench, screwdriver and new oil filter. You will also want to have some rags or paper towels handy in case of any spills.

Next: locate the filter in your engine bay and use the oil filter wrench to loosen it. Once it is loose enough, remove the filter and dispose of it properly. Be sure to inspect the old filter for any damage or signs of wear before disposing of it.

Then: coat the new oil filter with a thin layer of fresh oil before installing it in its place. Make sure that you tighten it to the manufacturer’s specifications in order to prevent any leaks. Replace the drain pan and fill the engine with fresh oil. Finally, start up your car and check for any leaks or other issues.

By following these steps, you can effectively and safely change your car oil filter without causing any further damage. This will help to ensure that your engine is running optimally and that your filter system is free from leakage.
