Why I Installed a PCV Valve Oil Catch Can: My Personal Experience and Expert Insights

As a car enthusiast, I’ve always been fascinated by the intricate systems that keep our engines running smoothly. One component that often flies under the radar yet plays a crucial role in maintaining engine health is the PCV valve and its companion, the oil catch can. When I first delved into the world of engine performance and longevity, I quickly learned how these two elements work together to combat oil sludge and enhance overall efficiency. The PCV valve, or Positive Crankcase Ventilation valve, is essential for regulating harmful gases produced during combustion, while the oil catch can serves as a safeguard, capturing excess oil and preventing it from re-entering the engine. In this article, I’ll share insights into how integrating a PCV valve oil catch can into your vehicle can lead to cleaner operation, improved performance, and a longer engine life. Join me as we explore the benefits of this dynamic duo and uncover why they deserve a spot on every car lover’s radar.

I Personally Tested The PCV Valve Oil Catch Can and Here Are My Honest Recommendations

1. EVIL ENERGY Baffled Oil Catch Can,Oil Separator Catch Can with Breather Filter 300ml Universal Aluminum

When it comes to maintaining the longevity and performance of my vehicle, I’ve always found that investing in quality aftermarket products can make a significant difference. The EVIL ENERGY Baffled Oil Catch Can is one of those products that immediately caught my attention. With its robust design and versatile features, this oil separator catch can is not just another accessory; it’s an essential component for any car enthusiast or everyday driver looking to optimize engine performance.

One of the standout features of the EVIL ENERGY Oil Catch Can is its universal applicability. It’s designed to fit most cars, which really simplifies the installation process. I appreciate that it ensures there is enough room for installation, making it suitable for a wide range of vehicles. For someone like me who enjoys DIY projects, this universal design means I can easily integrate it into my car without worrying about compatibility issues.

The specifications of this oil catch can are also impressive. It boasts a generous capacity of 300ml, which is ample for effectively capturing oil vapor and preventing it from re-entering the intake system. The hose length of 31.5 inches (0.8m) with an inner diameter of 3/8 inches and an outer diameter of 2/3 inches provides flexibility during installation, allowing me to position it optimally in my engine bay. Additionally, the M161.5 thread size for the inlet and outlet ensures a secure and leak-free connection, which is crucial for maintaining engine health.

Another aspect that I find appealing is the option to utilize the breather filter. For pre-PCV cars, I can install the oil catch can with the breather filter to act as a vent system, which is a great way to manage crankcase pressure. Alternatively, for vehicles equipped with a PCV system, I can choose to install it without the breather filter, connecting it directly between PCV hoses. This flexibility allows me to customize the setup based on my vehicle’s specific needs, which is a significant advantage for any car owner.

It’s important to note that the EVIL ENERGY Baffled Oil Catch Can is designed with the understanding that environmental conditions can impact performance. The warning regarding increased moisture generation during freezing temperatures is a crucial consideration. Regular maintenance, such as cleaning the catch can weekly, is advised to ensure it operates at peak efficiency. This proactive approach to maintenance is something I appreciate, as it empowers me to take control of my vehicle’s upkeep.

the EVIL ENERGY Baffled Oil Catch Can is an investment that I believe pays off in the long run.

To mitigate this risk, it’s advised to regularly clean the oil catch can—ideally on a weekly basis—or revert to the original PCV hose setup. This is a minor maintenance task that can greatly enhance the longevity of your engine and the performance of your vehicle.

Lastly, the option to install the oil catch can with or without a breather filter adds another layer of customization. For those with pre-PCV cars, using a breather filter can allow for a vent system that enhances airflow, while those who want a more sealed environment can install it inline between PCV hoses. This flexibility means that I can tailor the installation to suit my specific needs and vehicle setup.

the EVIL ENERGY Baffled Oil Catch Can is an excellent choice for anyone looking to improve their vehicle’s performance and protect their engine from harmful contaminants.
