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.
