We put six years of experience into a design to achieve the ultimate in performance and longevity for your 6.7 Cummins. You must invest in durable, high-quality components to maximize performance and longevity.
The billet valve cover has been one of the staple upgrades now for all Cummins enthusiasts alike. But adding a sleek, customized look to your engine bay is just part of the appeal, as it provides superior protection and durability when compared to stock covers.
This article will outline the benefits of an upgrade to a billet valve cover 6.7 Cummins, the main issues to be considered by the owner when making such a purchase, and installation steps one can follow in case one prefers to do it themselves.
What is the Role of the Valve Cover?
The valve cover acts to prevent contaminants from entering the valve train components of an engine and keeps them well-lubricated.
In a 6.7 Cummins engine, however, it normally comes with a factory plastic valve cover. This might get brittle over time and lose its sealing properties until it gives way to oil leakage and other debris. It’s on these counts that upgrading to a billet aluminum valve cover will provide a more reliable and durable solution.
Why Upgrade to a Billet Valve Cover?
Billet valve covers are made from solid blocks of aluminum, hence stronger and more durable than the traditional sealed metal or plastic covers. Here is why they vastly upgrade your 6.7 Cummins:
1. Improved strength and protection
The construction of the billet valve cover is heavy-duty for great durability, especially when you use your Cummins in harsh conditions, such as towing or off-road. Unlike plastic covers that may warp or crack over time, bullet covers resist the extreme temperatures and pressures an engine requires without compromising its structure.
2. Better aesthetic appeal
A billet valve cover makes your engine look sleek and shiny. Whether for performance or customizing your truck, a bullet cover just exudes class—insinuating that you are proud of your vehicle.
3. Improved Oil Control
Some billet valve covers feature integrated baffles and oil separators, offering better control of oil vapor. This feature is especially useful if you are running a high-performance build, as it helps to prevent excessive oil blow that can affect engine performance.
Choosing the Right Billet Valve Cover for Your 6.7 Cummins
When selecting a billet valve cover for your 6.7 Cummins intake manifold, consider the following factors:
1. Compatibility with Engine Modifications
If your engine has modifications like larger injectors, upgraded turbochargers, or high-performance fuel systems, choose a billet cover designed to accommodate these changes. Some covers offer additional clearance or fittings to support such modifications.
2. Ventilation and Oil Management
Many billet valve covers feature enhanced ventilation systems that help reduce crankcase pressure. Look for covers with built-in oil separators or PCV (Positive Crankcase Ventilation) ports to manage oil vapor and reduce emissions.
3. Aesthetic Preferences
Billet valve covers come in various finishes and designs, from raw aluminum to powder-coated colors. Consider a finish that complements your truck’s color scheme and your style. A cover with custom engravings or logos can also add a unique touch.
Key Benefits of Upgrading to a Billet Valve Cover
The billet valve cover changes the game regarding engine health and performance. Discussed herein are some advantages that make this an upgrade worth its price on your 6.7 Cummins.
Longer Engine Life
Because the billet valve cover itself is made from solid aluminum, it is designed to hold up under extreme conditions much better than its conventional valve cover counterpart. It acts as a great shield and resists thermal degradation; hence, it helps in increasing the life of an engine.
Reduced Oil Blow-by and Pressure Build-up
A frequent issue with ordinary valve covers is the problem of blow-by: when the gases from the combustion process leak by the piston ring into the crankcase, it results in contamination of oil and a pressure increase. Billet valve covers have superior ventilation designed into them, enabling better control of these pressures.
Noise Reduction
Due to their more robust construction, billet covers have the potential to reduce the noise related to the engine’s vibration. This brings out a quieter drive, especially for people who travel considerable distances or even tow heavier loads often.
How to Choose the Right Billet Valve Cover
When selecting a billet valve cover, consider the following aspects to ensure compatibility and the best performance:
1. Material Quality and Finish
Opt for covers made from high-grade aluminum to ensure long-lasting durability. Additionally, look for corrosion-resistant finishes like anodized coatings to prevent oxidation and maintain a sleek appearance.
2. Compatibility with Aftermarket Upgrades
If you’re planning future upgrades to your engine’s intake or exhaust system, ensure the valve cover allows for modifications. Some billet valve covers are built to accommodate additional breather ports, making it easier to integrate with custom setups.
3. Design Features
Consider models that come with pre-installed breather filters or baffling systems to reduce oil consumption and enhance crankcase ventilation. These features are beneficial for those pushing their Cummins engines to high-performance limits.
Step-by-Step Guide to Installing a Billet Valve Cover
Tools and Materials Needed
Before beginning, ensure you have the following tools and materials:
- Ratchet and socket set
- Screwdriver
- Torque wrench
- Gasket and sealant (if required)
Step-by-Step Installation
Remove the Factory Valve Cover
- Disconnect any components attached to the stock cover, such as the breather hoses or PCV valves. Use a ratchet to unbolt the stock cover from the cylinder head carefully.
Prepare the Surface for Installation
- Clean the gasket surface on the cylinder head to ensure a proper seal. Removing old gasket material is crucial to avoid leaks.
Install the New Billet Valve Cover
- Position the new billet cover over the cylinder head, aligning it with the bolt holes. Carefully tighten the bolts using a torque wrench, following the manufacturer’s specifications.
Conclusion: Is a Billet Valve Cover Worth the Investment?
