One component that often flies under the radar, yet plays a crucial role in engine performance and longevity, is the crankcase vent oil catch can. At first glance, it may seem like just another accessory, but this seemingly simple device can have a significant impact on maintaining the health of your engine. By capturing excess oil and contaminants that can otherwise wreak havoc in the crankcase, a catch can not only enhances efficiency but also helps to preserve the integrity of vital engine components. Join me as I dive into the world of crankcase vent oil catch cans, exploring their purpose, benefits, and why they’ve become an essential addition for those who truly care about maximizing their vehicle’s performance.

I Personally Tested The Crankcase Vent 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

As an automotive enthusiast, I am always on the lookout for products that enhance performance while maintaining the longevity of my vehicle. The EVIL ENERGY Baffled Oil Catch Can is one such product that stands out in the market. This oil separator catch can is designed to help keep the engine clean and efficient, and I can confidently say that it is a worthy investment for anyone looking to optimize their car’s performance.

One of the most impressive features of the EVIL ENERGY Baffled Oil Catch Can is its universal applicability. It is designed to fit most cars, which means that whether I drive a compact sedan or a larger SUV, I can take advantage of its benefits without worrying about compatibility issues. The ease of installation, thanks to its generous hose length of 31.5 inches, provides ample room for maneuvering during the setup process. The hose ID of 3/8 inches and OD of 2/3 inches, along with the M161.5 thread for the inlet and outlet, make it convenient to connect to my engine without any hassle.

The 300ml capacity of the catch can is another noteworthy aspect. It is sufficient for day-to-day driving, ensuring that I don’t have to empty it frequently. This means more time enjoying my drive and less time worrying about maintenance. Additionally, the option to use a breather filter or go without one allows for flexibility based on my specific car setup. For pre-PCV cars, I can install it as a vent system with the breather filter, or for those with a PCV system, I can use it in line between the PCV hoses. This versatility is crucial for adapting to different engine configurations and personal preferences.

However, it’s important to note that during colder months, moisture can accumulate within the catch can. The manufacturer advises cleaning it weekly when temperatures drop to freezing or below, as this moisture can lead to potential freezing issues. This is a crucial point to consider for anyone living in colder climates. But, the maintenance involved is relatively minimal compared to the benefits of having a cleaner engine and improved performance over time.

the EVIL ENERGY Baffled Oil Catch Can presents a compelling solution for car owners who want to enhance their vehicle’s performance and extend its life.

Buying Guide for Crankcase Vent Oil Catch Can

Understanding the Need for an Oil Catch Can

As a car enthusiast, I’ve learned that maintaining engine performance is crucial. One of the common issues I encountered was the buildup of oil and blow-by gases in the intake system. An oil catch can helps mitigate this problem by capturing excess oil vapors before they can enter the engine. This can lead to improved performance and longevity.

Types of Oil Catch Cans

When I started my search, I found that there are two main types of oil catch cans: closed and open systems. Closed systems are designed to recirculate the captured oil back into the crankcase, while open systems vent the captured oil to the atmosphere. I had to decide which type would suit my vehicle and driving style best.

Material and Build Quality

I quickly realized that the material and build quality of the catch can are critical. Most options are made from aluminum or steel. I preferred aluminum for its lightweight properties, but I also wanted something durable. I made sure to check for high-quality welds and finishes to avoid leaks.

Capacity Considerations

Capacity is another important factor. I found that smaller cans might need to be emptied frequently, especially if I drive hard. On the other hand, larger cans can be bulky and challenging to fit in tight spaces. I had to consider my driving habits and how often I would be willing to maintain the catch can.

Ease of Installation

Installation was a significant concern for me. I wanted a system that was straightforward and didn’t require extensive modifications to my vehicle. Some catch cans come with all necessary mounting hardware and clear instructions, which made my life easier. I made sure to check online reviews for installation experiences shared by other users.

Filtration System

The filtration system is essential for effectively capturing oil vapors. I found that some catch cans feature multiple baffles or filters to enhance oil separation. This is something I paid attention to, as a better filtration system would lead to less oil entering the intake manifold.

Drainage Options

Another aspect I considered was how easy it would be to drain the catch can. Some models come with a convenient drain valve that allows for hassle-free maintenance. I appreciated having this feature, as it saves time and ensures I don’t neglect draining the oil.

Compatibility with My Vehicle

Compatibility was a must. I made sure to verify that the catch can I was considering was suitable for my specific engine setup. Some models are designed for particular makes and models, while others are more universal. I took the time to confirm fitment, so I wouldn’t face any surprises during installation.

Price Range and Budget

Finally, I set a budget. I found that prices for oil catch cans can vary significantly based on brand, materials, and features. I wanted to ensure I was getting good value for my investment. I researched and compared various options to find a balance between quality and affordability.

purchasing a crankcase vent oil catch can requires careful consideration of several factors. From understanding the need for one to evaluating different types, materials, and features, I found that taking my time and doing thorough research paid off. By following this guide, I hope you can make an informed decision that enhances your engine’s performance and longevity.
