Review OFFENHAUSER Valve Cover Engine Breather

The Offenhauser 4039 Valve Cover Engine Breather is a high-performance component designed to improve the overall effectiveness of your engine's breathability and emission control systems. This valve cover breather is specifically engineered for Offenhauser V8 and Alcohol Drag Racing engines.

This valve cover breather is constructed mostly with billet aluminum for enhanced durability and heat resistance. The billet aluminum material allows it to withstand the extreme temperatures and pressures generated during racing. It features a generous size of 4 inches by 3.75 inches, which allows for optimal airflow and oil separation, reducing the risk of cratering and oil foaming.

Its design includes two oil reclaim ports that direct clean oil back into the crankcase, ensuring optimal oil reutilization. The pleated debt separator element helps to minimize the amount of foam and condensation that enters the crankcase, enhancing the engine's overall performance and efficiency.

Additionally, the Offenhauser 4039 Valve Cover Engine Breather boasts an adjustable pressure relief valve, which helps to maintain the crankcase pressure within acceptable limits. It features a 10 psi spring, but it can easily be swapped out for other spring strengths to better cater to the engine's unique requirements.

Installation of the Offenhauser 4039 Valve Cover Engine Breather is made simple with the inclusion of mounting hardware fitting various Offenhauser V8 engines. The product also comes with a breather hose and an additional 1/8 NPT breather fitting, providing versatility for different installation scenarios.

For elite racing enthusiasts, the Offenhauser 4039 Valve Cover Engine Breather underscores their commitment to pushing boundaries and seeking the best possible performance from their engines. Its high-performance features, durability, and adaptability make it a must-have accessory for those chasing championships on the track.

Offenhauser 4039 valve covers are aftermarket parts commonly used in hot rods and racing engines to improve breathability and reduce crankcase pressure. Here are some potential pros and cons of buying an Offenhauser 4039 valve cover:

1. Improved Breathability: By providing an outlet for crankcase gases, these valve covers can help reduce crankcase pressure and improve filling of the intake manifold, leading to better engine performance.

2. Enhanced Appearance: Offenhauser valve covers have a classic, streamlined design that is highly sought after in the hot rod and racing communities, making them an attractive upgrade for many engine enthusiasts.

3. Durability: Offenhauser valve covers are often made from high-quality materials such as aluminum or magnesium, which can provide superior strength and longevity compared to stock valve covers.

4. Customization: These valve covers allow for various customization options, including the addition of oil filler caps, breather tubes, and other performance-enhancing features.

1. Cost: Offenhauser valve covers can be quite expensive compared to stock valve covers, making them a significant investment for many car or engine owners.

2. Complexity: Installing aftermarket valve covers can be a complex process, requiring specialized tools and knowledge. In some cases, professional installation may be necessary.

3. Clearance Issues: Depending on the specific engine and application, clearance issues may arise when using aftermarket valve covers. Careful measurement and potential modifications may be required to ensure a proper fit.

In summary, buying an Offenhauser 4039 valve cover can offer significant performance benefits, such as increased breathability and improved engine performance, as well as aesthetic appeal. However, it's essential to consider the potential costs, complexity of installation, and potential clearance issues before making a decision. If you have the necessary resources and are looking for a high-performance upgrade for your engine, an Offenhauser valve cover could be an excellent investment. Otherwise, it may be more cost-effective to stick with stock valve covers. Ultimately, the decision depends on your budget, flexibility, and goals for your engine or vehicle.
