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

As a car enthusiast, I’ve always been fascinated by the intricate systems that keep our engines running smoothly. Among these, the PCV (Positive Crankcase Ventilation) valve plays a crucial role in maintaining engine efficiency and longevity. However, one often overlooked component that can significantly enhance this system is the oil catch can. I remember the first time I learned about the PCV valve oil catch can—it was like uncovering a hidden gem in the world of automotive maintenance. This clever device not only prevents harmful oil vapor from re-entering the intake system but also contributes to cleaner engine performance. In this article, I’ll delve into the importance of PCV valve oil catch cans, exploring how they work, their benefits, and why they should be a staple in any car enthusiast’s toolkit. Whether you’re looking to boost your engine’s performance or simply want to extend its life, understanding the role of an oil catch can is a vital step in your automotive journey.

I Personally Tried the PCV Valve Oil Catch Can and I’m Sharing My Honest Recommendations Below

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

I recently came across the EVIL ENERGY Oil Catch Can, and I must say, I am quite impressed with its features and potential benefits for car enthusiasts and everyday drivers alike. This universal baffled catch can kit is designed to enhance your vehicle’s performance by effectively managing oil vapors and moisture within the engine. It’s a product that not only promises to extend the life of your engine but also maintain optimal performance, making it a worthwhile investment for anyone who values their vehicle.

One of the standout features of this oil catch can is its universal applicability. It can be installed in most cars, which is a significant advantage for those of us who may not own a specific make or model. The installation process is straightforward, provided there’s enough room in your engine bay. This flexibility makes it an attractive option for a wide range of vehicle owners, whether you’re driving a compact car or a larger SUV.

The dimensions of the hose are also thoughtfully designed, with a length of 2.6ft (0.8m) and an inner diameter of 3/8″ and outer diameter of 2/3″. This sizing allows for an easy fit within most engine compartments. Additionally, the catch can has a capacity of 300ml, which is sufficient for daily driving needs without frequent emptying. The M161.5 threads on the inlet and outlet ensure a secure connection, minimizing the risk of leaks and enhancing durability.

Another feature that I find particularly appealing is the option to install the oil catch can with or without a breather filter. For those of us with pre-PCV cars, the breather filter allows for a vent system that can be beneficial in preventing pressure build-up. On the other hand, for vehicles utilizing a closed system, the catch can can be installed in line between the PCV hoses, acting as a seal can. This versatility means that I can tailor the installation to fit my specific vehicle needs, ensuring optimal performance regardless of the setup.

However, it is essential to note the caution regarding moisture accumulation in colder temperatures. The manual advises that when temperatures drop to freezing or below, the crank vent system may generate more moisture, which could lead to freezing risks. This is a critical consideration for those living in colder climates. Regular cleaning of the oil catch can is advised, or one might consider reverting to the original PCV hose during extreme weather conditions to avoid potential issues.

What truly sets EVIL ENERGY apart is their commitment to customer service. They stand behind the quality of their product, offering hassle-free returns or exchanges in case of any quality issues. Additionally, their customer service team is readily available to address any questions or concerns. This level of support provides peace of mind, especially for those who may be new to engine modifications or installations.

In summary, the EVIL ENERGY Oil Catch Can is a fantastic option for anyone looking to enhance their vehicle’s performance while managing oil vapors effectively. Its universal design, flexible installation options, and robust customer service make it a compelling choice. If you’re serious about maintaining your vehicle’s health and performance, I highly recommend considering this oil catch can. It’s an investment that can pay off in the long run, providing you with better engine performance and potentially saving you from costly repairs down the road.

Why a PCV Valve 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 made a noticeable difference for me is installing a PCV valve oil catch can. This relatively simple addition has provided several benefits that I didn’t fully appreciate until I experienced them firsthand.

First and foremost, the catch can effectively reduces oil blow-by, which is a common issue in many engines. I noticed that by capturing excess oil vapors and preventing them from re-entering the intake system, my engine operates more efficiently. This means cleaner air-fuel mixtures and improved combustion, which ultimately translates to better performance and fuel economy. I’ve found that my engine runs smoother, and I’ve even observed a slight increase in power.

Another significant advantage of the oil catch can is that it helps keep my engine internals cleaner. Before I installed it, I was concerned about carbon buildup and sludge forming in the intake manifold and valves. Since adding the catch can, I’ve experienced less gunk accumulation, which has led to reduced maintenance and cleaner engine components. This proactive approach has given me peace of mind, knowing that I’m taking steps to prolong the life of my engine

Buying Guide for PCV Valve Oil Catch Can

Understanding the Purpose

I’ve always been interested in keeping my engine running smoothly, and one of the best ways to do that is by using a PCV valve oil catch can. This device captures the oil vapors that can accumulate in the intake system, preventing them from causing issues like carbon buildup. By installing a catch can, I noticed a significant improvement in my engine’s performance and longevity.

Types of Oil Catch Cans

When I first looked into oil catch cans, I discovered there are two main types: passive and active. Passive cans rely on gravity to collect the oil, while active cans use a filtration system or baffle to separate oil from the air. I found that the type I choose depends on my specific engine setup and personal preference.

Material and Build Quality

I always check the material of the oil catch can before purchasing. Most are made from aluminum or plastic, but I personally prefer aluminum due to its durability and heat resistance. I also pay attention to the welds and fittings; they need to be strong and reliable to withstand the engine’s vibrations.

Size Matters

The size of the catch can is crucial. I’ve learned that a larger capacity means I can go longer between emptying it, but it also needs to fit in my engine bay. I measure the available space before making a decision to ensure it won’t interfere with any other components in my engine compartment.

Ease of Installation

Installation can be a hassle, so I always look for catch cans that come with clear instructions and all necessary fittings. Some models are designed for direct bolt-on installation, while others may require some customization. I prefer options that simplify the process as much as possible.

Drainage Options

I’ve come across catch cans with different drainage methods. Some have a simple manual drain, while others feature a petcock or automatic drain system. I find that an easy drainage option saves me time and effort, especially after extended drives.

Filter Quality

The filter is a crucial part of the catch can system. I always check if the can comes with a high-quality filter that can effectively separate oil from air. A good filter can make a significant difference in the overall performance of the catch can.

Price and Budget

I’ve learned to set a budget before diving into the options available. Prices can vary widely depending on the brand, materials, and features. I weigh the benefits against the cost to make sure I’m getting value for my money without compromising quality.

Customer Reviews and Recommendations

Before making my final decision, I always read customer reviews and seek recommendations from fellow car enthusiasts. Real-world experiences can provide insights that technical specifications might not cover. I take note of recurring themes in the feedback, whether positive or negative.

Choosing the right PCV valve oil catch can has made a noticeable difference in my vehicle’s performance. By considering the factors outlined in this guide, I feel more equipped to make an informed decision that suits my needs. Whether I’m looking for durability, ease of installation, or effective filtration, I know that taking the time to research will pay off in the long run.
