Crankcase Evacuation System

What Is a Crankcase Evacuation System?

A crankcase evacuation system, sometimes referred to as an exhaust evacuation kit, is an essential component in many high-performance and racing vehicles. It plays a crucial role in maintaining the health and efficiency of your engine. But what exactly is a crankcase evacuation system?

A crankcase evacuation system is designed to remove harmful gases, pressure, and excess moisture from the engine's crankcase. It helps to create a controlled vacuum inside the crankcase, which offers several benefits:

- **Reduced Pressure:** The system reduces the pressure inside the crankcase, preventing oil leaks and gasket failures. Excessive pressure can force oil past seals and into places it shouldn't be, causing engine damage.

- **Improved Piston Ring Seal:** By maintaining a vacuum in the crankcase, a crankcase evacuation system helps improve the seal of the piston rings. This can lead to increased power and efficiency.

- **Reduced Blow-By:** Blow-by is the escape of combustion gases past the piston rings into the crankcase. A crankcase evacuation system helps reduce blow-by, which can contaminate the oil and reduce engine performance.

- **Enhanced Ring and Cylinder Lubrication:** Proper evacuation helps ensure that the oil is distributed effectively to lubricate the piston rings and cylinder walls, preventing friction-related damage.

- **Moisture Removal:** The system removes excess moisture from the crankcase, which can be especially beneficial in humid environments. Moisture can lead to corrosion and other issues.

What Happens When There Is a Vacuum in the Crankcase?

When a vacuum is maintained in the crankcase, several positive effects occur:

- **Improved Piston Ring Seal:** The vacuum helps keep the piston rings seated against the cylinder walls, reducing blow-by and increasing engine efficiency.

- **Reduced Oil Leaks:** Lower crankcase pressure reduces the likelihood of oil leaks and gasket failures, ensuring that oil stays where it belongs.

- **Enhanced Lubrication:** With a controlled vacuum, oil can be more precisely distributed to lubricate critical engine components, minimizing wear and tear.

- **Prevention of Contamination:** The vacuum prevents the entry of contaminants into the crankcase, helping to maintain oil quality and engine cleanliness.

Overall, a crankcase evacuation system plays a vital role in optimizing engine performance, protecting engine components, and extending the life of your vehicle.

How Much Does a Crankcase Evacuation Kit Cost?

The cost of a crankcase evacuation kit can vary depending on several factors:

1. **Kit Components:** Crankcase evacuation kits can include various components, such as hoses, fittings, vacuum pumps, and catch cans. The complexity and completeness of the kit can impact its cost.

2. **Brand and Quality:** Reputable brands with a history of quality and performance may offer higher-priced kits. High-quality components are essential to ensure the system's effectiveness.

3. **Application:** The cost may also vary based on the specific requirements of your vehicle. Some kits are designed for specific engine types or applications, and these factors can influence the price.

As a general guideline, crankcase evacuation kits can range from around $100 to several hundred dollars or more. It's important to choose a kit that matches your engine's needs and performance goals while staying within your budget.
