Why an SBC Valve Cover Breather is Necessary
As someone who has spent countless hours working on my small block Chevy (SBC) engine, I’ve come to appreciate the importance of a valve cover breather. At first, I didn’t think much of it, but I quickly learned that this seemingly simple component plays a crucial role in engine performance and longevity.
One of the primary reasons I find a valve cover breather indispensable is its role in managing crankcase pressure. When the engine runs, combustion gases can escape into the crankcase, leading to increased pressure. Without a proper breather, this pressure can cause oil leaks and even damage seals. By allowing these gases to escape, the breather helps maintain optimal pressure levels, which ultimately protects the engine and prolongs its life.
Additionally, I’ve noticed that having a breather improves the overall efficiency of my engine. By ensuring that fresh air can enter the crankcase, it promotes better oil circulation. This not only keeps the engine running cooler but also aids in the lubrication process, reducing wear on vital components. In my experience, an SBC with a functional valve cover breather runs smoother and more reliably than one without.

My Buying Guides on Sbc Valve Cover Breather
When I started diving into the world of SBC (Small Block Chevrolet) engines, one of the components that caught my attention was the valve cover breather. It’s a small but crucial part that plays a significant role in maintaining the performance of my engine. Here’s what I learned along the way, which I hope will help you in your purchasing journey.
Understanding the Function of a Valve Cover Breather
Before I made my purchase, I took the time to understand what a valve cover breather does. Essentially, it allows fresh air to enter the crankcase while enabling the escape of excess gases and pressure. This is vital for keeping the engine running smoothly and preventing oil leaks or build-up.
Types of SBC Valve Cover Breathers
During my research, I discovered that there are several types of SBC valve cover breathers. Here’s a breakdown of the most common ones:
- Push-In Breathable Filters: These are designed to push directly into the valve cover. I found them easy to install and replace, making them a popular choice for many enthusiasts.
- Screw-In Breathable Filters: These are threaded and provide a more secure fit. I appreciated their durability, especially for high-performance applications.
- Breather with PCV Valve: Some breathers come with a Positive Crankcase Ventilation (PCV) valve. This is a great option if you want to control emissions and maintain optimal pressure in the crankcase.
Material Considerations
I learned that the material of the breather can affect its performance and longevity. Here are the common materials I came across:
- Aluminum: Lightweight and corrosion-resistant, aluminum breathers are a favorite among performance enthusiasts.
- Plastic: Generally more affordable, but I noticed they might not withstand high temperatures as well as aluminum.
- Stainless Steel: While they can be pricier, stainless steel breathers offer excellent durability and a sleek look.
Size and Compatibility
Before making my decision, I had to ensure that the breather would fit my specific SBC setup. I measured the diameter of the valve cover openings and checked compatibility with my engine model. Many manufacturers specify the size, so I made sure to verify this before purchasing.
Performance Features
I also looked into various performance features that could enhance my engine’s efficiency. Some breathers come with advanced filtration systems or are designed to reduce oil mist. These features can be beneficial, especially if I’m pushing my SBC to the limits.
Brand Reputation
During my search, I paid attention to brand reputation. I found that trusted brands often provide better quality and support. I read reviews and asked fellow enthusiasts about their experiences with specific brands. This helped me narrow down my options and feel more confident in my choice.
Price Range
Lastly, I considered my budget. SBC valve cover breathers can range from $10 to over $100. I realized that while I wanted to save money, investing a bit more in a quality breather could save me headaches in the long run.
Final Thoughts
After considering all these factors, I finally made my choice for an SBC valve cover breather. It’s a small part, but it significantly contributes to the overall performance of my engine. I hope my experience and insights will help you find the perfect breather for your SBC engine! Happy shopping!
