Types of Oil Filter Failures and How to Prevent Them

Maintaining your vehicle's engine is crucial for ensuring its longevity and performance. One essential component that plays a pivotal role in engine health is the oil filter, as it removes contaminants from engine oil, ensuring only clean fluid circulates through the machine. However, oil filter failures can lead to many problems, including engine damage, making it critical to understand how they occur. In this blog, we will explore various types of oil filter failures, providing brief insight into how to prevent them.

Gasket and/or Seal Failure

One common type of oil filter failure occurs when the gaskets and seals within the oil filter deteriorate. The gaskets and seals inside a filter are essential for preventing oil leaks and ensuring everything remains intact, especially when exposed to high temperatures and constant cycling. Consequently, oil can leak from the filter, causing inadequate lubrication and, in severe cases, engine damage. To prevent this, regularly inspect your oil filter for any signs of leakage or seepage, and make sure to replace the oil filter during your routine oil change service while adhering to manufacturer recommendations.

Clogging Due to Contaminants

Another common issue that can lead to oil filter failure is clogging, as the oil filter accumulates dirt, debris, and contaminants from the engine oil over time. When the filter becomes excessively clogged, it restricts oil flow, causing inadequate lubrication and increased engine wear. This can manifest itself as a decrease in engine performance and fuel efficiency.

To avoid this, opt for high-quality oil filters with superior filtration capabilities, as clogging risk is reduced when filters with a high micron rating capture finer contaminants. Regularly check your oil pressure gauge as well to monitor oil flow, and replace the filter if you notice a pressure drop.

Pressure Gauge Abnormalities

The oil pressure gauge is a crucial instrument for monitoring the health of your engine's lubrication system and abnormalities in oil pressure, which can indicate a problem with the oil filter. A sudden drop in oil pressure may result from a clogged filter, bypass valve failure, or other issues with the filter element. On the other hand, excessively high oil pressure can damage the filter and cause oil leaks.

In order to prevent such abnormalities, routinely check the oil pressure gauge to ensure it registers within the normal range specified in the vehicle's owner's manual. If you notice any fluctuations or unusual readings, have your oil filter and lubrication system inspected by a qualified mechanic.

Bypass Valve Failure

It is typical for oil filters to have a bypass valve that serves as a safety feature. When the filter becomes clogged and oil flow is severely restricted, the bypass valve opens so that unfiltered oil can reach critical engine components. While this can prevent engine damage in the short term, it is not a long-term solution. Bypass valve failure can lead to unfiltered oil reaching your engine, potentially causing wear and damage.

As a result of various damage risks, it is essential to regularly inspect your oil filter to ensure the bypass valve functions correctly. If you suspect the valve is frequently open due to clogging, address the root cause using a more efficient oil filter.

Triple R (Reuse, Recycle, Replace)

To prevent oil filter failures and maintain optimal engine health, consider the “Triple R” approach: Reuse, Recycle, and Replace.

• Reuse: Some high-quality oil filters offer options for cleaning and reusing the filter element, but one must follow the manufacturer's recommendations and guidelines before reusing.

• Recycle: Properly dispose of used oil filters at recycling centers or in accordance with local regulations to prevent environmental pollution.

• Replace: Follow your vehicle manufacturer's recommendations for oil filter replacement intervals. Regular replacements with high-quality filters can significantly reduce the risk of filter failures.

Conclusion

Regular maintenance of your vehicle's oil filter is essential to prevent various oil filter failures. By addressing issues related to gaskets and seals, clogging, pressure gauge abnormalities, bypass valve failure, and adopting the “Triple R” approach, you can ensure that your engine receives clean and adequate lubrication, extending its lifespan and maintaining peak performance.
