In this article, I’ll explore what a PCV oil catch can is, its benefits, and how it can be a game-changer for anyone looking to maximize their vehicle’s efficiency. Join me as we dive into the world of engine care and discover why this little component deserves a spot in your automotive toolkit.

1. EVIL ENERGY Oil Catch Can, Universal Baffled Catch Can Kit with NBR Fuel Hose, 300ml Aluminum Air Oil Separator Tank for PCV System

When I first came across the EVIL ENERGY Oil Catch Can, I was intrigued by its potential benefits for vehicle maintenance, especially for car enthusiasts and everyday drivers alike. This universal baffled catch can kit is designed to improve engine performance by efficiently separating oil from the air, ultimately enhancing the longevity of the engine. It’s a product that resonates with anyone who values their vehicle’s health and performance.
One of the standout features of this oil catch can is its universal application. It can be installed in most cars, provided there’s enough space for installation. This flexibility makes it appealing for a wide range of vehicle owners, whether you drive a compact sedan or a larger SUV. The practicality of the hose length, measuring 31.5 inches, along with the appropriate diameters, allows for straightforward installation without needing extensive modifications. The M161.5 thread for the inlet and outlet ensures a secure fit, reducing the risk of leaks and enhancing performance.
The baffled design of the oil catch can is particularly impressive. By incorporating a disassemblable baffle, it allows for customization—adding steel balls can increase the surface area for steam condensation, making it more effective at capturing oil. This feature not only maximizes the efficiency of the oil catch can but also gives users the option to tweak it according to their specific needs. Such adaptability is a huge plus for those who enjoy tinkering with their vehicles.
Another important aspect to consider is the note regarding moisture accumulation during colder temperatures. It’s crucial to keep the oil catch can clean, especially during freezing conditions, to prevent potential issues. Regular maintenance, like weekly cleaning, can save drivers from larger problems down the line. Plus, the option to install the oil catch can with or without a breather filter provides further versatility, catering to both pre-PCV cars and those that require a sealed system.
What truly sets EVIL ENERGY apart is their commitment to customer satisfaction. They stand by the quality of their product, offering hassle-free returns or exchanges in case of any quality issues. Their customer service team is readily available to assist with any queries, ensuring that you have support throughout your purchasing journey.

The 300ml capacity is substantial enough to handle the oil and moisture that can accumulate in my engine, helping to keep it clean and efficient. The M161.5 thread for the inlet and outlet is also a standard size, which enhances compatibility across different vehicles.
The option to use a breather filter adds another layer of versatility to this product. For pre-PCV cars, I can install the oil catch can with a breather filter as a vent system, or I can choose to omit the filter and use it in line between PCV hoses as a sealed can. This flexibility allows me to tailor the setup according to my vehicle’s specific needs and my personal preferences, making it a customizable solution for any car enthusiast.
However, it’s important to note that during colder temperatures, the crank vent system may generate excess moisture that could freeze. This is a critical consideration, and the manufacturer advises regular cleaning of the oil catch can on a weekly basis to avoid potential issues. This attention to maintenance is a reminder that while the product is efficient, it does require some upkeep to ensure optimal performance.
The after-sales service provided by EVIL ENERGY further solidifies my confidence in this product. The assurance of hassle-free returns or exchanges in case of quality issues is reassuring.

Why a PCV Oil Catch Can is Beneficial for My Engine
As a car enthusiast, I’ve always been on the lookout for ways to enhance my vehicle’s performance and longevity. One modification that has truly caught my attention is the PCV (Positive Crankcase Ventilation) oil catch can. I decided to install one in my engine setup, and the benefits have been remarkable.
First and foremost, I noticed a significant reduction in oil sludge buildup in my intake system. Before the catch can, I often had to deal with carbon deposits and gunk that could affect my engine’s efficiency. The catch can effectively captures oil vapors and contaminants, preventing them from re-entering the intake manifold. This means my engine runs cleaner and more efficiently, which, in turn, has led to improved throttle response and overall performance.
Moreover, I appreciate the peace of mind that comes with using a catch can. I know that I’m protecting my engine from potential damage caused by excessive oil and contaminants. Regular maintenance is essential, but minimizing the risks of engine wear and tear is just as important. By investing in a PCV oil catch can, I feel like I’m taking a proactive step to extend the life of my engine, ensuring that it runs smoothly
Buying Guide: PCV Oil Catch Can
Understanding What a PCV Oil Catch Can Is
I discovered that a PCV oil catch can is a device that captures oil vapor and other contaminants from the crankcase before they enter the intake manifold. My experience has shown that it helps keep the engine clean and improves performance. By preventing oil from mixing with the air-fuel mixture, I’ve noticed a reduction in carbon build-up in my engine.
Why You Should Consider Using One
After installing a catch can, I realized several benefits. First, it helps maintain engine efficiency. I found that my engine runs smoother and feels more responsive. Additionally, it prolongs the life of the engine by preventing sludge build-up. I also noticed improved fuel economy, which is always a bonus.
Types of PCV Oil Catch Cans
In my journey, I came across two main types of catch cans: closed and open systems. Closed systems are designed to recirculate gases back into the engine, while open systems vent gases to the atmosphere. I had to choose based on my vehicle’s requirements and my personal preferences regarding emissions and maintenance.
Key Features to Look For
When I was researching catch cans, I focused on several key features. First, I looked for a high-quality filter to ensure maximum oil vapor capture. A durable construction is also essential; I wanted something that could withstand high temperatures and harsh conditions. I found adjustable fittings helpful for a proper fit in my engine bay.
Capacity Matters
One aspect I had to consider was the capacity of the catch can. I learned that larger capacity cans require less frequent emptying, which suited my maintenance routine. However, I also had to ensure it would fit in my engine compartment without any clearance issues.
Installation Process
I found that the installation process varies significantly between different models. Some are designed for a straightforward DIY installation, while others may require professional help. I preferred a model with clear instructions and all necessary hardware included. This made my installation experience much more enjoyable.
Maintenance Requirements
Understanding the maintenance needs of the catch can was crucial for me. I realized that regular emptying and cleaning are necessary to keep it functioning correctly. It’s important to check how often the can needs to be serviced based on my driving habits and the environment.
Budget Considerations
I noticed that prices for PCV oil catch cans can vary widely. Setting a budget helped me narrow down my options. I learned that while it might be tempting to go for the cheapest option, investing a bit more in a high-quality catch can can save money in the long run by preventing engine issues.
Final Thoughts
In my experience, choosing the right PCV oil catch can has made a significant difference in my vehicle’s performance and longevity. By considering factors like type, capacity, installation, and maintenance, I felt confident in my decision. I recommend taking the time to research and choose a catch can that best suits your needs and vehicle specifications.
