The CCV system connects to the factory intake or intake manifold, in the case of diesels – the intake air horn. The factory intake air horn draws a vacuum across the CCV system by way of BERNOULLIS PRINCIPAL to pull crankcase gases out of the engine and reburn them in the motor. The problem is often as a diesel wears out they endup with a lot of blow by and oil injection into the inlet of the turbo. The truck consumes this oil as part of emissions standards and best practices of crank case evacuation.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: How does the CCV upgrade system work once installed?\u003cbr\u003e\u003c\/strong\u003eA2: The CCV upgrade system, once installed, allows for more efficient removal of oil from the CCV supply line using two integrated differential drop devices in the CCV block. This method, commonly used in marine and high-output diesel applications, is passive and has no moving parts. It helps maintain a clean intake track and prevents hot air and oil from entering the system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Why is the factory CCV system problematic?\u003cbr\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003eA3: The factory CCV system tends to fail over time, and when it does, it allows boost pressure from the CCV to enter the intake track through the intake air horn. Additionally, it is not serviceable, and replacing it requires removing the entire driver's side valve cover, including injectors and fuel lines, which is time-consuming and costly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What is the advantage of removing the factory CCV component?\u003cbr\u003e\u003c\/strong\u003eA4: Removing the factory CCV component eliminates a potential failure point and provides a more convenient and safe oil fill location at the front of the motor.
