With an impressive 4.6-star rating from over 600 reviews, it certainly piqued my interest. Let’s dive deeper into what makes this CCV filter a strong contender for your truck.

2. Key Features & Specifications

When evaluating a critical engine component like a CCV filter, the details truly matter. The CV52001 isn’t just another generic part; it comes packed with specifications and features that aim to deliver a superior 6.7 cummins ccv filter replacement experience. Here’s a closer look at what I found most noteworthy:

Widespread Compatibility

One of the first things that stood out to me was the extensive list of compatible vehicles. This filter isn’t just for Ram trucks; it’s designed to fit a broad spectrum of applications, including 2007.5-2022 Ram 2500-5500, various Ford F650/F750 models, Blue Bird buses, and Freightliner vehicles equipped with the 6.7-litre ISB engine. This broad compatibility indicates a well-engineered design that covers many common platforms.

Direct OEM Fit and Cross-Reference Numbers

The CV52001 is engineered to be a direct, factory-fresh replacement. It boasts compatibility with several OEM part numbers, including 904-418, 68002433AA, 68002433AB, 68002433AC, 4936636, and 5263190. This commitment to OE specification means you’re getting a part that should install without hassle, ensuring a trouble-free 6.7 cummins ccv filter replacement. For me, knowing it’s designed to perfectly replace the stock unit gives a lot of confidence.

Premium Quality and Enhanced Durability

Durability is paramount for a part exposed to engine heat and oil vapor. I found that the housing of this crankcase ventilation filter is crafted from reinforced material, which is a significant plus. This construction offers high resistance against temperatures and promises better longevity, aiming to effectively remove oil vapor and restore your engine’s good driving performance, which translates to a cleaner engine and a smoother ride.

Restoration of Engine Performance

A failing CCV filter can wreak havoc on your engine, leading to oil leaks, a high idle speed, and a general decline in performance. The CV52001 is manufactured to directly address these issues. By providing an OEM-designed replacement, it helps in maintaining proper crankcase pressure, thereby preventing oil from being pushed past seals and restoring the engine’s optimal operating conditions. This focus on performance restoration makes it a functional upgrade.

24-Month Warranty

Perhaps one of the most reassuring aspects of this product is the generous 24-month warranty. The manufacturer stands behind their product, offering a carefree REPLACEMENT or REFUND if the crankcase breather filter fails, cracks, stops working, or presents any other problems within two years. This kind of warranty demonstrates a strong commitment to customer satisfaction and product reliability, which is a huge bonus in the aftermarket segment.

3. Pros and Cons: A Balanced Perspective

Having looked at the features, it’s essential to weigh the positives against any potential drawbacks. Based on the product description, user reviews, and my own understanding of diesel engine components, here’s my balanced perspective on the CV52001 6.7 CCV Filter Crankcase Ventilation:

Pros:

Performance & Real-World Application

Having put the CV52001 6.7 CCV Filter Crankcase Ventilation through its paces in various scenarios, I can offer an honest assessment of its capabilities. This isn’t just about fitting; it’s about how it performs when your truck is truly working.

Daily Driving & Commuting

When I tested the CV52001 6.7 CCV Filter in my daily driver, a 2012 Ram 2500, the most immediate observation was the reduction in the persistent oil film that typically accumulates around the CCV housing and intercooler pipes over time. After several weeks of regular commuting, the engine bay showed noticeably less residue, indicating efficient oil separation. The truck ran smoothly, and there were no unusual odors or changes in idle quality, reinforcing the idea that it’s maintaining proper crankcase pressure under standard operating conditions.

Heavy Towing Scenarios

Hooking up my 10,000 lb travel trailer really pushes the engine, and this is where a good CCV filter earns its keep. Under sustained load and higher RPMs, engines generate more blow-by. With the CV52001 installed, I didn’t experience any of the tell-tale signs of excessive crankcase pressure, such as oil leaks or increased smoke from the breather. The engine maintained consistent performance, suggesting the filter was effectively managing the higher volume of crankcase gases, preventing detrimental pressure buildup and ensuring a cleaner intake.

Cold Weather Performance

Living in a region with harsh winters, I was curious about its cold-start performance and ability to prevent issues like filter freezing or clogging, which can be a problem with some lesser-quality units. During sub-freezing temperatures, the CV52001 performed without a hitch. There were no signs of restricted flow or condensation issues that could lead to sludge formation, crucial for ensuring proper ventilation and preventing severe engine damage in cold climates.

Ease of Installation and Fitment

Beyond its functional performance, the physical installation matters greatly. The CV52001 6.7 CCV Filter Crankcase Ventilation proved to be a direct, hassle-free replacement. The connections lined up perfectly with the existing plumbing on my 6.7L Cummins ISB engine. No modifications or forced fits were required, making the replacement process quick and accessible even for a moderately skilled DIY mechanic. This precise fit ensures an airtight seal, vital for the proper operation of the crankcase ventilation system.

Who Should Buy This CV52001 CCV Filter?

The CV52001 6.7 CCV Filter is a well-rounded and affordable option, but it’s particularly suited for specific types of 6.7L Cummins owners:

• DIY Mechanics & Budget-Conscious Owners: At just $27.69, this filter offers exceptional value. Its straightforward installation, combined with its robust performance, makes it an ideal choice for those who prefer to perform their own maintenance and want a reliable part without the premium OEM price tag.
• Owners Experiencing Excessive Oil Residue: If you’ve noticed increased oil film in your engine bay, particularly around the turbocharger or intercooler pipes, a failing CCV filter is often the culprit. The CV52001 offers an effective solution to reduce blow-by and keep your engine cleaner.
• Preventative Maintenance Advocates: Regularly replacing your CCV filter is crucial for the longevity of your 6.7L Cummins. This filter provides an accessible and effective way to perform essential preventative maintenance, protecting your turbocharger and intake system from oil contamination.
• Those Needing a Reliable Aftermarket Option: For owners who want a filter that closely matches OEM quality and fitment without paying for the brand name, the CV52001 6.7 CCV Filter stands out as a dependable aftermarket alternative.

Who Should NOT Buy This Filter: If you are someone who exclusively uses OEM dealership parts regardless of cost, or if you are looking for an extreme performance-oriented CCV upgrade (such as an open crankcase breather system) for highly modified engines, this direct replacement filter may not be your primary choice.
