The 2018 Ram 2500 is a powerful and reliable truck that is known for its durability and performance. One important component of this truck is the crankcase filter, which plays a crucial role in maintaining the engine’s health and efficiency. In this article, we will discuss everything you need to know about the 2018 Ram 2500 crankcase filter and its importance.

What is a Crankcase Filter?

A crankcase filter, also known as a breather filter or PCV filter, is a component that filters the air entering the crankcase of an engine. It helps prevent contaminants, such as dirt, debris, and oil vapors, from entering the engine’s ventilation system. This ensures that only clean air is circulated within the engine, promoting optimal performance and longevity.

The Role of the Crankcase Filter

The crankcase filter serves several important functions in your 2018 Ram 2500. Firstly, it helps prevent harmful contaminants from entering the engine, which can cause damage to internal components and reduce overall performance. Secondly, it helps maintain the proper balance of air pressure within the crankcase, preventing excessive pressure buildup that can lead to oil leaks and other issues. Lastly, it helps reduce emissions by capturing and filtering out oil vapors before they are released into the atmosphere.

Signs of a Failing Crankcase Filter

Like any other component in your vehicle, the crankcase filter may eventually wear out and require replacement. Here are some common signs that indicate a failing crankcase filter:

1. Reduced Engine Performance

If you notice a decrease in your 2018 Ram 2500’s overall performance, such as reduced power or acceleration, it could be due to a clogged or dirty crankcase filter. A restricted filter can limit the amount of clean air entering the engine, affecting its efficiency and power output.

2. Increased Oil Consumption

A failing crankcase filter can lead to increased oil consumption as contaminants bypass the filter and mix with the oil. This can result in higher oil consumption and the need for more frequent oil changes. If you notice a significant decrease in oil levels between oil changes, it could be a sign of a failing crankcase filter.

3. Check Engine Light

If the onboard diagnostics system in your 2018 Ram 2500 detects an issue with the crankcase filter, it will trigger the check engine light. If the light comes on, it is essential to have your vehicle inspected by a qualified technician to determine the exact cause and address it promptly.

Maintenance and Replacement

Regular maintenance and timely replacement of the crankcase filter are crucial to ensure the optimal performance and longevity of your 2018 Ram 2500. It is recommended to refer to your vehicle’s owner’s manual for the manufacturer’s recommended maintenance schedule and replacement intervals. However, as a general guideline, it is advisable to inspect the crankcase filter during every oil change and replace it if necessary.

Choosing the Right Crankcase Filter

When it comes to selecting a replacement crankcase filter for your 2018 Ram 2500, it is essential to choose a high-quality filter that meets or exceeds the original equipment specifications. OEM (Original Equipment Manufacturer) filters are specifically designed for your vehicle and ensure proper fitment and filtration efficiency.

Professional Installation

While replacing the crankcase filter may seem like a simple task, it is always recommended to have it done by a qualified technician or mechanic. They have the necessary skills and expertise to perform the replacement correctly and ensure that the new filter is installed securely.


The crankcase filter is a vital component of your 2018 Ram 2500’s engine, and regular maintenance and replacement are essential to keep it functioning properly. By paying attention to the signs of a failing crankcase filter and addressing them promptly, you can ensure optimal engine performance and longevity for your truck.
