5 Benefits of Getting a Replacement for the Valve Cover of Your Cummins Engine

Tameless Performance 2006 to present 5.9 6.7 Cummins Valve Cover Raw

The smaller additions usually provide the most value when it comes to upgrading a Cummins Diesel engine. The valve cover is one of such components. It protects the valvetrain and is involved in sealing, noise abatement, and oil control.

While there are many ways to enhance your engine, getting a Tameless Performance Aluminum Valve cover will surely do the trick. This article lists the five best reasons to consider upgrading.

  1. Better Protection For The Engine

Trying to keep unwanted and oil out is the basic function of the stock valve cover. But, with time the factory Cover breaks down, or becomes brittle due to warping or cracking creating a leak. This will affect the performance of the engine in performance as well efficiency overall.

With the Tameless Performance Valve Cover, you won't have to worry about performance. Made out of aluminum, the cover provides long lasting protection and superior seals. And on top of that, it protects the engine from harmful debris and other contaminants.

  1. Improved Heat Dissipation

Heavy duty diesel engines generate a considerable amount of heat. Acting more effectively than OEM plastic or composite options, Aluminum allows the valve cover to dissipate heat more effectively due to its thermal conduction characteristics.

This not only helps in stabilizing engine temperatures under load but, helps improve performance, engine life, and engine health, particularly when towing or driving long distances.

  1. Reduced Engine Noise and Vibration

Stock valve covers tend to worsen noise and vibration issues as they age or the vehicle is subjected to excessive use. Aluminum valve covers trim excess engine and top-end vibration noise and dampening vibration of the engine head, allowing a quiet drive.

This permits reduced component wear due to improved harmonics and increased rigid body, enhanced engine efficiency for diesel owners who regularly tow, or everyday drivers means a quieter cabin and reduced fatigue during prolonged journeys.

  1. Better Aesthetics and Customization

For truck lovers, the aesthetics of the engine bay is just as crucial as the performance. The Tameless Performance valve cover offers a clean extravagant look that instantly elevates the visual appeal under hood which improves overall aesthetics.

Impressing onlookers at a truck show or simply taking pride in an intricately constructed engine bay, a billet-aluminum valve cover is another addition to the list of components that enhance your Cummins’ beauty as well as its ferocity. On top of that, its non-equilibrium finish ensures it will look as pristine in years to come as it does now.

  1. Long Term Reliability and Maintenance Made Easy

Tameless valve covers are easier to remove for periodic engine maintenance, and as for the stubborn valve cover gaskets, it's highly unlikely they will fail. All of this is in addition to being able to endure a great amount of stress. The cover is designed to withstand cracking, heat warping, and even the inevitable wear that factory options succumb to.

For the long-haul owners of Cummins, this is an upgrade that means further mitigated repairs down the line, cleaner internals, and less anxieties about oil slipping out or foreign fluids seeping in.

Why Changing the CCV Filter is Important

Most Cummins engines have a stock valve cover that integrates the Crankcase Ventilation (CCV) system, which controls oil mist and gas emissions by routing them back to the intake. Unfortunately, this system poses a number of problems for modified, performance-oriented vehicles.

Reasons to Remove It:

  • Increased Reduction of Dirty gases
  • Reduced Carbon contraction in Valves
  • Prevention of Unburned Hydro-carbon Secondary Combustion
  • Increased Airflow on Tuned Engines
  • Elimination of Oil Mist Recontamination

Tameless Performance produce valve covers that do not have an integrated CCV filter, letting the owner use external oil/air separators and catch cans, leading to a simpler and more effective system.

Supporting Mods/BP

Below are some guidelines if you plan to upgrade the valve cover while removing the CCV system concurrently.

🔧 Add an Oil Catch Can or Separator

The proper routing of vapor and oil mist through a quality catch-can system leads to improved performance without reaching the intake.

Upgrade Seals and Fasteners

Make sure to use good quality gaskets and meet proper torque specs with the right bolts (bolts are included with the Tameless Performance Valve Cover) to achieve a reliable seal.

Routine Maintenance

Even after the CCV has been removed, it is best practice to check and clean the intake system from time to time to get rid of any remaining buildup.

Be Aware of Emissions Regulations

Removing the stock CCV system may or may not be legal in all jurisdictions. Make sure to confirm your local emissions regulations prior to doing this modification.

FAQ

Q1: Does performance improve by removing the CCV filter?

In a word, yes—better airflow, higher intake charge temperatures, and reduced carbon buildup are to be expected.

Q2: Is there a need to tune the truck after removing the CCV?

That is directly correlated to your overall build. Some configurations do gain from ECU tuning and produce more power.

Q3: Will this impact the life of the engine?

This is true for the opposite—actually cleaner internals and lower contamination would prolong the lifespan of the engine.

Q4: What other components must I buy while deleting CCV filter?

A Tameless Performance valve cover and a well-engineered oil/air separator are essential.

Q5: Is removal of CCV suitable for all Cummins trucks?

All depends on use case and local laws. For high-performance or emissions-sensitive builds, it’s best to consult an expert.

Conclusion

Installing a Tameless Performance aluminum Cummins valve cover is a smart choice for any serious Cummins enthusiast. This cover provides improved sealing, enhanced heat dissipation, reduced operational noise, increased airflow, and dependable performance. It is a smart investment when coupled with removing the stock CCV filter and adding an appropriate separator system.

This upgrade allows for improved airflow, temperature control, and long-term protection, whether you drive daily, tow, or have a performance build.
