Review MOROSO Crankcase Evac System Billet Breathers

Moroso 68866 Crankcase Evac Billet Breathers are a high-performance solution for managing crankcase ventilation in race and high-performance applications. These billet breathers are CNC-machined from 6061-T6 aluminum, ensuring a strong and durable construction that can withstand the rigors of motorsport competition.

The Moroso 68866 Crankcase Evac Billet Breathers feature a -8 AN O-Ring threaded inlet and outlet connections, allowing for easy installation and integration with various crankcase ventilation systems. The inlet connection is designed to accept Moroso's Crankcase Evac valves (sold separately), which can be used to control the flow of crankcase gases based on engine vacuum or pressure.

These billet breathers are also equipped with a removable 5-micron filter element, which helps to prevent contaminants and debris from entering the crankcase and potentially damaging engine components. The filter element can be easily removed and cleaned or replaced as needed.

Additionally, the Moroso 68866 Crankcase Evac Billet Breathers feature a baffled design, which helps to reduce crankcase pressure pulsations and improve overall engine performance. The baffles also help to prevent oil mist from escaping, which can help to keep the engine and surrounding areas cleaner.

These breathers are suitable for use in both naturally aspirated and forced-induction engines, making them a versatile option for a wide range of high-performance applications. With their strong construction, easy installation, and effective crankcase management capabilities, the Moroso 68866 Crankcase Evac Billet Breathers are an essential component for any serious racing or high-performance engine build.

Moroso 68866 Crankcase Evac Billet Breathers are aftermarket oil separators designed to improve the performance and appearance of your vehicle's crankcase ventilation system. Here are some pros and cons of buying these billet breathers:

1. Enhanced engine appearance: Moroso billet breathers have a polished finish, which can make your engine bay look more attractive and well-maintained.

2. Improved oil separation: These breathers use a high-flow, high-efficiency oil separator that can help to reduce crankcase pressure and improve oil circulation.

3. Reduced crankcase emissions: By separating oil mist from crankcase gases, the Moroso crankcase breathers can help to reduce crankcase emissions, which can be beneficial for both the environment and the performance of your vehicle.

4. Easy installation: These breathers are designed to be easy to install, and they come with all the necessary hardware and instructions.

1. Higher cost: Moroso billet breathers are more expensive than OEM or aftermarket plastic breathers.

2. Requires periodic maintenance: The oil separator in these breathers needs to be drained and cleaned periodically to maintain optimal performance.

3. Potential for oil leaks: Since these breathers use a billet aluminum construction, there is a risk of oil leaks if not installed properly.

Moroso 68866 Crankcase Evac Billet Breathers offer several advantages, including improved engine appearance, enhanced oil separation, reduced crankcase emissions, and easy installation. However, they also have some disadvantages, such as a higher cost, periodic maintenance requirements, and the potential for oil leaks. Ultimately, whether or not to buy these breathers depends on your budget, maintenance preferences, and desired performance benefits.

If you are looking for a high-performance, attractive crankcase ventilation solution and are willing to pay a higher price and perform periodic maintenance, then Moroso 68866 Crankcase Evac Billet Breathers may be a good choice for you. Alternatively, if you have a limited budget or prefer a lower-maintenance option, then you may want to consider OEM or aftermarket plastic breathers instead.
