Why Breathers for Valve Covers are Necessary
As someone who has spent countless hours tinkering with engines, I can confidently say that having breathers for valve covers is essential for optimal engine performance. One of the main reasons I value these components is that they help maintain proper crankcase pressure. When the engine runs, combustion gases can escape into the crankcase, leading to increased pressure. Without breathers, this pressure can build up, causing oil leaks or even damaging seals. I’ve seen firsthand how a simple breathers installation can alleviate these issues, keeping my engine running smoothly.
Another significant benefit I’ve experienced is the reduction of oil contamination. Over time, moisture and blow-by gases can accumulate in the crankcase, leading to sludge buildup. By incorporating breathers, I allow these harmful gases to escape, which helps keep the oil cleaner for longer. This not only enhances the longevity of my engine but also improves its overall efficiency. I’ve noticed that my oil stays fresher between changes, saving me both time and money in the long run.
Finally, I appreciate how breathers can enhance the overall performance of my engine. By promoting better airflow and ventilation, they contribute to a healthier combustion process. This can lead to improved horsepower and torque, which is something
My Buying Guide on Breathers For Valve Covers
When I first started modifying my engine, I quickly realized the importance of choosing the right breather for my valve covers. It may seem like a small detail, but the right breather can significantly affect engine performance and longevity. Here’s my comprehensive guide to help you navigate the options available.
Understanding Valve Cover Breathers
Before diving into the buying process, I found it essential to understand what valve cover breathers do. These components allow for the release of gases and pressure that build up in the engine’s crankcase. Proper ventilation is crucial to prevent oil leaks and maintain optimal performance.
Types of Breathers
- Push-In Breathers
- These are the most common type I encountered. They simply push into the valve cover and are easy to install. They can be a great choice if you’re looking for a straightforward solution.
- Screw-In Breathers
- I found screw-in breathers to be more secure, as they screw directly into the valve cover. This type is ideal if you want to ensure a tight fit and reduce the risk of oil leaks.
- PCV (Positive Crankcase Ventilation) Breathers
- If your engine has a PCV system, I recommend considering a PCV breather. It helps manage crankcase pressure while allowing for the removal of harmful gases.
Material Considerations
When I was searching for breathers, I realized that the material could impact performance and durability. Here are the common materials I came across:
- Aluminum: Lightweight and durable, I found aluminum breathers to be a great choice for performance applications.
- Plastic: Generally more affordable, plastic breathers can be a good option for budget builds, but I noticed they may not last as long under extreme conditions.
Size and Fitment
Getting the right size was crucial for me. I measured the opening on my valve covers to ensure compatibility. Most breathers come in standard sizes, but it’s always a good idea to double-check the specifications.
Performance Features
Some breathers come with advanced features that can enhance performance. When I was browsing, I looked for breathers with:
- Filters: These help keep contaminants out of the engine. I found that a breather with a good filter can improve longevity.
- Baffles: These reduce oil splash and help keep the breather functioning correctly, especially in high-performance engines.
Brand Reputation
I paid attention to brand reputation during my search. Established brands often provide better quality and customer support. I found brands like Moroso, Edelbrock, and Spectre to be reliable choices.
Price Range
Breathers can range from budget-friendly options around $20 to high-performance units that can exceed $100. I set a budget based on my needs and the level of performance I was aiming for.
Installation Process
Most breathers are straightforward to install, but I always appreciated products that came with clear instructions. I looked for breathers that included mounting hardware and were designed for easy installation.
Conclusion
In my experience, choosing the right breather for valve covers can make a noticeable difference in engine performance and reliability. By considering the type, material, size, features, brand reputation, price range, and installation process, I was able to find the perfect breather that suited my engine modifications. I hope this guide helps you in your journey to enhance your engine’s performance!
